Patented May 10, 1938 UNlTED STATES PATENT QFFlCE MACHINE FOR MAKING DECORATIVE MATERIAL Application December 2, 1936, Serial No. 113,882

This invention relates to automatic mechanism for producing running lengths of decorative material. Such material, in one form thereof, comprises lead or tin foil out in such manner asto provide a fringe pendant from a marginal portion thereof, said marginal portion being provided with a reenforcing binding which, in most cases, includes a flexible cord or strand extending through the bight thereof. The machine is also operative to produce a crinkling or crimping of the individual fringe forming appendages or elements, whereby. in the finished material, the fringe is furnished with a multiplicity of light reflecting facets so that a brilliant scintillating effect is attained by the reflection of light therefrom when the material is employed in use as an ornamental trimming or for other decorative purposes. 7

The invention has for its general object to provide a simple, cfficient and compact machine adapted to automatically and rapidly fabricate the elements making up decorative material of the type above referred to, and to produce the crinkled or crimped fringe structure of said material.

The invention has for an object to provide, in a machine of the kind above referred to, means for automatically and continuously withdrawing from a source of supply the various elements entering into the construction of said decorative material and thereupon bringing said elementstogether in proper assembled relation, and then advancing the assembled structure to and through a novel cutting or shearing mechanism adapted to produce in the lead or tin foil element a pendant fringe structure.

The invention has for a further object to provide, in such machine, means to crimp the fringe forming members whereby the fringe is corrugately crinkled to provide the same with angular light reflecting facets to thus render the fringe of sparkling effect in use.

Other objects of this invention not at this time more particularly enumerated will be understood from the following detailed description of the same.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which:

Fig. 9 is a fragmentary sectional view of a modified form of foil guide rod means.

Similar characters of reference are employed in the above described views, to indicate corresponding parts.

Referring to the drawings, the reference character l0 indicates a bottom frame plate and II a top frame plate, said plates being secured together in vertically spaced relation by intermediate vertical frame bars l2 extending between the respective corner portions thereof.

At its left hand end portion, as viewed in the 20 drawings, the top frame plate H is cut away to provide an opening l3 therethrough. This. opening I3 is bridged over by a bridge plate M which is suitably secured to said top frame plate II by bolts and nuts 15. At its inner lateral marginal portion said bridge plate I4 is cut away to provide a hatchway or passage 16 leading to the space beneath said top frame plate I l.

Afiixed to said bridge plate It is a bearing housing IT in which is mounted a suitable anti-fric- 0 tion bearing l8. Journaled in said bearing I8 is a rotatable upper spindle [9, which is retained in operative relation to the bearing I8 and its housing H by a keeper collar 26 suitably secured to its exteriorly and upwardly projecting free end portion. Threaded to and extending axially through. said spindle I9 is an adjusting member 2!, to the lower end of which is attached a conical hub member 22. Said hub member 22 is disposed beneath the top frame plate ll. Connected with the bottom frame plate In is a bearing housing and bearing 23 similar in kind to the housing I1 and its antifriction bearing I8, and journaled therein is an upstanding rotatable lower spindle 24 which is disposed in vertical or axial alignment with the upper spindle I9. Engaged on and carried by said lower spindle 24, so as to be vertically adjustable thereon, is a foil roll supporting sleeve 25 having at its upper end a conical hub member 26. A supply of lead or tin foil F, in the form of a roll 21 thereof wound upon a hub sleeve 28, is provided to supply this material subject to the operation of the machine. This roll is mounted over the lower porting sleeve 25 engages wedgingly in the lower end of its hub sleeve 28, while the hub member 22 of the upper spindle i9 engages wedgingly in the upper end of said hub sleeve 28, thus rotatably mounting the foil supply roll so that the foil may be drawn from the same. Said supporting sleeve 25 is provided with a manipulatable-thumb-screw 2% whereby the sleeve may be aflixed to the lower spindle 24 in desired adjusted position according to the height of the particular foil supply roll to be used. The hub member 22 of the upper spindle I9 is vertically adjustable so as to dispose the upper marginal portion of the foil material in proper alignment and registry with the operative mechanisms of the machine through which the foil material is to be passed.

Secured to and extending between the bottom and top frame plates H3 and H are one or more foil guide rods 36, at least one of which is disposed to direct the leading end of the foil into the proper path of movement to be traversed by the same when subjected to the action of the operative mechanisms of the machine.

Fixed upon the bridge plate I4 is an upstanding bracket 3! which supports a transversely disposed spindle 32. A supply of binder tape T, in the form of a roll 33 thereof, is rotatably mounted upon said spindle 32, so that said binder tape may be drawn from said roll and supplied subject to the operation of the machine.

Suitably affixed to the top frame plate H, in upstanding relation thereto, is a post 3 having affixed thereto a supporting flange 35 above which projects a vertical spindle 35. A supply of flexible cord or like material C, wound e. g. upon a spool 31, is provided to supply this material subject to the operation of the machine. The spool 3! is rotatably supported by the flange 35 and spindle 3% so that the cord C may be drawn from the spool and fed with the foil F and binder tape T into the machine.

The binder tape T extends from the roll 33 thereof downwardly through the hatchway or passage 5 provided in the bridge plate it, while at the same time cord C extends from spool 3 3' to pass through a guide opening 38 provided in the bridge plate M behind the hatchway or passage !6, so that the cord is fed with and beneath the binder tape T.

Mounted on the underside of the top frame plate H beyond the hatchway or passage IE is a tape folding and applying means adapted to fold the tape along its longitudinal axis so as to both envelop the cord C in the bight of such fold and embrace within the fold of the tape the upper longitudinal marginal portion of the foil, thus assembling these materials together in the desired manner subject to progressive movement through the machine for subsequent fringing and crimping operations.

The tape folding and creasing means comprises a pair of rotatable pressure rolls including a stationary roll 39 and an opposed adjustable roll 46. These rolls rotate about vertical axes adjacent to the underside of said top frame plate I l. The shaft ll of the stationary roll (-29 is journaled in a bearing sleeve 4! fixed in said top frame plate I I, and said shaft 4! is provided at its upper end with a driving sprocket 42. The shaft 43 of the adjustable roll it is journaled in a bearing sleeve 44 fixed in a transversely disposed bearing carrier 45, the latter being slidably disposed between guide pieces d6 upon the upper surface of said top frame plate ll. Said top frame plate H is provided with an opening 5'! to provide adjusting clearance for said bearing sleeve 44 which extends therethrough. The means for adjusting said bearing carrier 55 comprises a stationary bracket 48 which is secured to the top frame plate H. Threaded through the upstanding lug 49 of said bracket 48 is an adjusting screw 50, the shank 5| of which has a swivel connection with the upstanding lug 52 of said bearing carrier 45. Said shaft 43 of the adjustable roll if! is provided at its upper end with a driving sprocket 53. By adjustably moving the bearing carrier 45, the roll 40 may be moved toward or from the stationary roll 39 so as to adjust the nip of the rolls for the proper reception, passage and treatment of the materials passed to and between said rolls. Afiixed to the underside of said top frame plate H, in advance of said pressure rolls 39-9, is a folder member 54, the converging sides of which extend toward and adjacent to the nip of the pressure rolls 39i0, so that as the horizontally entering tape T passes into and through said folder member, accompanied by the underlying cord C and the upper marginal portion of the foil F, the side marginal portions of the tape, oppositely extending from its longitudinal medial line, will be gradually downturned and folded respectively over opposite faces of the upper marginal portion of the foil F, thus forming the tape into a binding which embraces the foil material, while at the same time enclosing the cord C in longitudinal extension through the bight or fold of the binding thus formed. The under surface of the tape is provided with a suitable adhesive which will adhere the fold thereof to the surfaces of the foil F under the pressure applied to the folds by the action of the pressure rolls 39- 40. The pressure rolls 39-40 not only aid in drawing the materials from the respective supplies thereof, but also, while creasing and ironing down the folds of the binder tape into smooth adhering relation to the foil F, also assist in advancing the thus assembled materials onwardly through the machine subject to subsequent operations.

Beyond said pressure rolls 39- l0 is arranged a pair of rotatable feed rolls which extend vertically between the bottom and top feed plates l0l|. Said feed rolls comprise a stationary feed roll 55 and an opposed adjustable feed roll 56. provided with a journal 57 extending upwardly through a bearing sleeve 58 which is fixed in said top frame plate ll. Affixed to the upper free end of said journal 5'? is a driving sprocket 59. Mounted in connection with the bottom frame plate i6 is a journal stud 60 to rotatably support the lower end of said stationary feed roll 55 in connection with a suitable anti-friction bearing M with which said lower end portion of the latter is provided. At its upper end, said adjustable feed roll 56 is provided with a journal 62 extending upwardly through a bearing supported by an adjustable bearing carrier 63, and at its lower end, said adjustable feed roll 56 is rotatably supported by a journal stud and anti-friction bearing, similar to those serving the stationary feed roll 55, and carried by a corresponding adjustable bearing carrier 63. Said bearing carriers 63 are similar in construction to that abovedescribed as supporting the adjustable creasing roll til, being slidable between guide-pieces 64, and being subject to adjusting movement by means of adjusting screws 65 which are threaded through bracket pieces 66 affixed to the frame plates. By adjustably moving the bearing car- At its upper end, the stationary feed roll is I riers 63, the feed roll 56 may be moved toward or from the stationary feed roll 55 so as to adjust the nip of these rolls properly to the assembled materials passing therebetween. A drive sprocket 61 is afiixed to the upper journal 62 of the adjustable feed roll 56. To efiect a positive grip and feed of the materials through and by said feed rolls 5556, the adjustable feed roll 56 provided, adjacent toits upper end, witha plu rality of circumferentially spaced radially pro-- jecting drive pins 68, and the stationary feed roll 55 is provided with a cooperating annular clearance groove or channel 69 toreceive and pass said pins. Said drive pins 68 are sharply pointed, and,

r consequently, as the tape bound margin of the foil F passes between the feed rolls 55-56, said pins will laterally pierce the same, thus positively engaging and propelling forward the material, since these pins enter the material as it approaches the nip of said feed rolls and withdraw therefrom as the material leaves the nip of and rolls.

Beyond said feed rolls 5556 is arranged foil slitting or shearing means whereby the body of the foil material extending below the tape bound marginal portion thereof may be cut to provide a dependant fringe. This slitting or shearing means comprises a rotatable vertically disposed cutter roll 10 having at its upper end a journal H which extends upwardly through a bearing sleeve 12 mounted in the top frame plate ll. Aflixed to the upper free end of said journal TI is a driving sprocket l3. Mounted in connection with the bottom frame plate 10 is a journal stud 14 to rotatably support the lower end of "said cutter roll 10 in connection with a suitable antifriction bearing 15 with which said lower end portion of the cutter roll is provided. At its upper end portion the cutter roll 10 is provided with a plurality of circumferentially spaced radially projecting drive pins 16 to engage and propel the tape bound marginal portion of the foil through the slitting or shearing means of which the cutter roll is a part. The cutter roll is provided,

around its cylindrical surface, with a plurality of radial cutting elements 11, which extend longitudinally of the roll. These cutting elements are somewhat obliquely inclined to the axis of the roll, for purposes presently to be explained. Cooperative with said cutter roll is a rotatable vertically disposed backing roll 18 against the cylindrical surface of which the sharp knife-like edges of the cutting elements impinge, so as to shear through the foil material as the latter is backed or supported by the backing roll when passing between the same and said cutter roll. At its upper end, said backing roll 18 is provided with a journal H! which extends upwardly through a bearing sleeve supported by an adjustable bearing carrier 8|, and, at its lower end, said backing roll is provided with an anti-friction bearing 82 in connection with which it is rotat ably supported by a journal stud 83 carried by a corresponding adjustable bearing carrier 84. The bearing carriers 8| and 84 are respectively slidably mounted upon the top and bottom frame plates for movement between guide-pieces 64, and the adjusting movements of said carriers are controlled by adjusting screws 85 which are threaded through stationary brackets 86 respectively affixed to said top and bottom frame plates. By adjustably moving the bearing carriers 8l-B4, said backing roll 18 may be positioned relative to the cutter roll H1 in such manner as to assure .a proper impingement thereupon of the cutting elements 11. A drive sprocket 81 is affixed to the upper journal 19 of said backing roll. At its upper end portion, thebacking roll 18 is provided with an annular clearance groove or channel 88 to receive and pass the drive pins with which said cutter roll is provided. l

In the operation of the machine, as the foil F is advanced to and passes between said cutter roll 10 and backing roll 18, that portion of the foil body dependant from. its tape bound upper marginal portion is engaged between the knifelike edges of the cutting elements 11 and the surface of the backing roll 18. Owing to the oblique disposition or inclination of the cutting elements 1'! relative to the vertical axis of the backing roll 18, the point of impingement of each cutting element edge shifts longitudinally along the backing roll surface as the rolls rotate. The result of this mode of operation is to cause the cutting elements to progressively cut through the foil material with .a shearing action as distinguished from a chopping cut involving the simultaneous action of the entire length of a cutting edge at the instant of impingement upon the backing roll as would be the case if the cutting elements Tl were arrangedparallel to the axis of the backing roll. Preferably the inclination of the cutting elements 71 is from left to right leading from the upper end of the cutter roll 10,

which, as shown, rotates in a clockwise direction, 3

since by such disposition the cutting elements are caused to shear downwardly through the foil body from. a selected point adjacent to its upper bound marginal portion. The described arrangement of the foil slitting or shearing means assures a clean cut with minimum risk of tearing or undesirably mutilating the foil, and consequently a clean cut fringing of the foil body to a desired depth or extent is easily attained without risk of the fringe elements failing to be released from between the cutting elements or teeth; the width of the fringe elements being determined by the spacing of the cutting elements Tl around the cutter roll circumference.

Beyond the foil slitting or shearing means, the machine is provided with means for crimping the cut fringe, to thereby corrugately crinkle the fringeelements transversely, whereby light reflection from the fringe produces a sparkling or scintillating effect. This crimping means comprises a pair of rotatable vertically disposed crimping rolls. These crimping rolls comprise a stationary female crimping roll 89 and an opposed adjustable male crimping roll 90. The surfaces of said rolls are provided with annular corrugations; those of the male crimping roll 90 mating or dove-tailing with those of the female crimping roll 89. One of the rolls, as e. g. the female crimping roll 89, is provided at its upper end with a journal 9i which extends upwardly through a bearing sleeve 82 mounted in the top frame plate ll. Afiixed to the upper free end of said journal 9! is a driving sprocket 93. Mounted in connection with the bottom frame plate H1 is a journal stud 94 to rotatably support the lower end of said female crimping roll 89 in connection with a suitable anti-friction bearing 95 with which the latter is provided. At the upper end of the other roll, e. g. the male crimping roll 96, is a journal 96 which extends upwardly through a bearing sleeve 8'! supported by an adjustable bearing carrier 98, and, at its lower end, said roll is provided with an anti-friction bearing 99 in connection with which it is rotatably supported by a journal stud I00 carried by a corresponding adjustable bearing carrier IOI. The bearing carriers 38 and IIJI are respectively slidably mounted upon the top and bottom frame plates for movement between guide-pieces 64, and

; the adjusting movements of said carriers are controlled by adjusting screws I02 which are threaded through stationary brackets I03 respectively affixed to said top and bottom frame plates. By adjustably moving the bearing carriers 98 and IBI, the adjustable crimping roll may be moved toward and fromv the stationary crimping roll so as to properly relate the same in spaced opposition to pass the foil fringe therebetween in such manner as to effect the desired crinkling of the individual fringe elements by pressing the latter between the mating male and female annular corrugations with which the crimping rolls are provided. A drive sprocket I04 is affixed to the upper journal 96 of said adjustable crimping roll 90. At its upper end portion said male crimping roll is provided with a plurality of circumferentially spaced radially projecting drive pins I05 to engage and propel the tape bound marginal portion of the foil through the crimpling rolls. The crimping roll 89 is provided at its upper end portion with an annular clearance groove or channel I06 to receive and pass the drive pins I05 of crimping roll 90.

After passing through the fringe crimping means, the decorative material is completed and is passed to any suitable mechanism (not shown) for winding or folding up the same or otherwise arranging it for packaging ready for commercial distribution.

It will'be understood that in cases Where itis desired to furnish the decorative material with straight and smooth or uncrinkled fringe, the crimping rolls may be withdrawn from service position or omitted.

Illustrative of one form of driving means for transmitting operative movement to the several sets of rolls, included in the functional mechanisms of the machine, there is shown a chain drive IB'I which engages the several sprockets with which the various roll devices are provided. A selected journal of one of the roll devices may be utilized as a drive shaft. For example, the upper journal 9i of the crimping roll is provided with a shaft extension I33 to which an electric motor (not shown) may be connected in driving relation thereto, or, in fact, any other means for transmitting operating power to said shaft extension may be employed. "I'he drive chain It'll is driven in a clockwise direction, i. e. in the direction of the arrow :0 appearing in Fig. 2. The chain is run exteriorly around the drive sprocket 93 of the female crimping roll 8Q and then back and exteriorly around the drive sprocket I04 of the male crimping roll; thence the chain runs exteriorly around the sprocket 81 of the backing roll I8 and then back and exteriorly around the sprocket T3 of the cutter roll lil; thence the chain runs exteriorly around the sprocket 59 of feed roll 55 and then back and exteriorly around the drive sprocket Bl of the feed roll 55; thence the chain runs eXteriorly around the sprocket 53 of the pressure roll 40 and then back and exteriorly around the sprocket 42 of the other pressure roll 39; and finally the chain runs around a tensioning sprocket I99, which is mounted in connection with the top frame plate ii, and then to and around an idler sprocket Hi3, also mounted on the top frame plate It, thence returning to sprocket 93 aforesaid. All this will be understood to best advantage from an inspection of Fig.

2 of the drawings. It will be obvious that the cooperating rolls of each set of roll devices will be rotated in opposite directions by the abovedescribed drive chain arrangement, whereby the various roll sets will function to advance the materials operated upon from one roll set to another while subject to the functional effects of the respective roll sets.

While the above described chain and sprocket drive means provides a satisfactory power transmission means for actuating the several roll sets of the machine, it will nevertheless be understood that such form of transmission means is illustrative of but one of many other forms of power transmission which might be employed. For example, instead of the chain and sprocket drive, a system of gearing could be employed, as will be readily understood by the skilled mechanic.

The transmission is located above the top frame plate as will be seen, and it is desirable to g,

guard the same, both to protect it and to safe-- guard the operator of the machine from possible injurious accidental contact therewith. To this end a covering guard plate III may be provided to extend thereover; said guard plate being supported upon carrying posts H2 secured to and upstanding from said top frame plate II.

The functioning of the several roll sets and the operation of the machine as a whole in carrying out its intended purposes will be understood, it 1 is believed, without need for further amplification. It will be obvious, however, that the machine may be used for the intended purposes in connection with various kinds of sheet material in addition to the foil material above mentioned. It will also be understood that, if desired, the incorporation of a reenforcing cord with the bound margin of the finished material may be omitted when its presence in the finished material is not desired.

Referring to Fig. 9, there is shown therein a modified form of foil guide rod which may be employed in place of the solid guide rod 30 which separates the unwinding course of the foil from the supply roll. This modified foil guide rod comprises a hollow or tubular rod II3 provided in its side walls with a series of discharge openings H4. Air under some pressure may be supplied to the interior of said rod H3 for discharge from the openings H4 toward the periphery of the foil roll adjacent to the point of separation of the run of foil being drawn therefrom. Such discharge of air tends to aid the separation of the foil run from the roll so as to assure against impedance of the proper movement of the foil from 1 the supply roll from any cause.

It will be obvious that many changes, in addition to those hereinabove referred to, could be made in the above described construction, and that many apparently widely different embodiments of the invention could be made without departing from the scope of the same as defined by the following claims. It is therefore intended that all matter contained in the above descrip tion or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
