DECORATIVE PIPING STRIPS Filed Sept. 5, 1952 United States Patent DECORATIVE PIPING STRIPS Theodore J. Boecker, Winchester, Mass., assignor to Boecker-Stuart, Inc., Cambridge, Mass., a corporation of Massachusetts Application September 5, 1952, Serial No. 308,116

Claims. (Cl. 154-536) This invention relates to improvements in decorative piping strips which are suitable for ornamentlng or finishing upholstery and leather and imitation leather products but which have especial utility as decorative piping for moccasin type shoes and slippers. More particularly, the invention provides such piping strips WhlCh may be manufactured with a substantial saving of material as compared with the comparable piping strips produced according to prior procedures.

Decorative piping strips of the variety to WhlCh the mvention relates have a bead strip of leather, woven cord, or other suitable material, exposed at intervals along that edge of the piping strip which is visible in a shoe or other article. The piping strip is wrapped around the bead strip but has spaced openings through WhlCh the bead strip is exposed.

Heretofore, the initial strip of material of which the piping strip is formed has been uniformly perforated with relatively large holes or cut-outs distributed unrformly throughout the length of the strip, and when this perforated strip is wrapped around a bead strip, portions of the latter are exposed where they cross the perforations, to provide a beaded edge having decorative character. However, the stock out out to provide the substantial perforations is entirely wasted.

It is among the objects of the invention to provide decorative piping strips having all of the decorative attributes of the prior comparable strips, but which may be produced more economically without any wastage of material. According to the invention, two similar ramose strips simultaneously are cut or dinked in a manner to utilize all of the material of the initial strip, each ramose strip having uniformly spaced tongues adapted to be wrapped around a bead strip to produce the same decorative eflect attained with the prior perforated strips.

Another object of the invention is to provide an intermediate product in the production of decorative piping strips comprising a ramose strip of flexible sheet material having relatively long uniformly. spaced tongues whose end portions are connected together by a relatively narrow strip of flexible material adhered to one side of the end portions of all of the tongues, whereby the uniform spacing of the tongues is maintained as they are successively wrapped around a bead strip.

further object of the invention is to provide a ramose strip of flexible sheet material having relatively long uniformly spaced tongues projecting from an intact marginal portion of the strip, the tongues being adapted to be wrapped around a bead strip in the manufacture of decorative piping strips, and the ends of all of the tongues being connected by a relatively strong strip adhered to the end portions of all of the tongues and adapted to be adhered to said intact marginal portion of the first mentioned strip when said tongues are wrapped around the bead strip, thereby to constitute a reinforcement through which stitches may pass when the decofative piping strip is being secured in a shoe or other arm e.

It is, moreover, my purpose and object generally to improve decorative piping strips, and the procedures of manufacturing such strips.

In the accompanying drawing:

Fig. 1 is a plan view of a strip of flexible sheet material showing how two of my ramose strips may be cut or dinked therefrom without wastage of any material;

Fig. 2 is a perspective of one of my ramose strips having adhesive material coating the upper surface thereof and having a relatively narrow strip of material adhered to the end portions of all of the tongues of the ramose strip;

Fig. 3 is a view similar to Fig. 2 showing the tongues of the ramose strip, with the narrow strip thereon, turned inward and adhered to the intact marginal portion of the ramose strip, the tongues being wrapped around a bead strip which is omitted excepting at the left hand portion of Fig. 3;

Fig. 4 is a cross-sectional view on line 4-4 of Fig. 3;

Fig. 5 is a view similar to Fig. 2 but showing the narrow strip adhered to the end portions of the tongues at their under sides, whereby this narrow strip may be stripped off after the tongues have been turned over a bead strip and adhered to the intact marginal portion of the ramose strip;

Fig. 6 is a view similar to Fig. 5 but showing the majority of the tongues after being turned inward and adhered, and showing the left hand end portion of the narrow strip in the process of being stripped from the tongues;

Fig. 7 is a cross-sectional view on line 7-7 of Fig. 6;

Fig. 8 is plan view of a fragment of a completed decorative piping strip embodying a cross-sectionally round bead strip;

Fig. 9 is a perspective of a portion of the forepart of a moccasin type shoe having my improved piping strip embodied therein; and

Fig. 10 is a plan view of parable piping strip with its 1y wrapped condition.

Referring to the drawing, the decorative piping strips of the invention are ramose strips 10, of leather or other suitably flexible material, having the relatively long tongues 10 extending in uniformly spaced parallelism, with each space 10 between adjacent tongues complementary to a tongue 10 whereby two of the ramose strips 10 may be cut, as by a dinking die, from a single wider strip 12 (Fig. 1), without any of the material of strip 12 being wasted.

Heretofore, such decorative piping strips have been made, as illustrated in Fig. 10, by cutting or dinking spaced holes 14 in a strip 12*- which usually is 1% or 1%," wide. The stock cut out to form the holes 14 is wasted.

According to the invention, two of 10 are cut or dinked from a strip 12 which may have width as little, or less than 1 /2", and the entire strip 12 is utilized, with substantial saving in material as compared with the 'prior procedures.

The flesh side of each ramose strip 10, assuming the strips to be of leather, is coated with a suitable adhesive which is indicated by the stippling at 16 in Figs. 2-6, adhesive on the prior strip of Fig. 10 also being indicated by stippling at 16*. The adhesive 16 may be rubber cement, or latex or any other suitable adhesive, and it may be coated all over the flesh side of the ramose strips 10, or may be coated only along the edge portion at the base of the tongues 10 and at the tip portions of the tongues, as shown in Fig. 5. In either case, the tongues 10 may be folded inward over a bead element 18 (Figs. 3, 6, 8 and 9) with the in-turned end of each tongue becoming adhered in its in-turned condition, and with the bead element 18 exposed at the regions where it crosses the spaces between tongues 10 Referring more particularly to Figs. 5 and 6, an adhesive strip 20 is shown adhered to the grain or finished side of a ramose strip 10, joining together the end portions of all of the tongues 10 of the strip. The strip 20 may, for example, be a strip of scotch tape, or the like, which readily may be adhered to the tongues as in Fig. 5, thereby to aid in maintaining the spaced relation of the tongues and to facilitate inturning of the tongues to their secured positions of Fig. 6, after which the adhesive strip 20 may be stripped oif. The head element 18, over which the tongues engage in spaced relation may be a strip of leather, as in Figs. 3 and 6, or may be a woven cord, or the like, as shown in Fig. 8. It should be understood that the adhesive strip ,20 of Figs. 5 and 6 may be omitted, if desired, but its presence a fragment of a prior combead strip shown in partialthe ramose strips Patented Mar. 29, 1955 facilitates in-turning of the spaced tongues by conventional or other iii-folding machinery, or by hand.

Figs. 2 and 3 illustrate an adhesive strip 22 adhered across the end portions of the tongues 10 at the flesh side or coated side of the strip and tongues, and this 'strip 22 becomes a permanent part of the ornamental piping strip inasmuch as it becomes engaged between the un-cut edge portion of the strip and the in-turned end portions of the tongues 10*. Here again, the strip 22 serves primarily to facilitate in-turning of the tongues, especially when the in-turning is accomplished by machine. However, the adhesive strip 22 may be a fabric strip of a nature to reinforce and strengthen the securement of the piping strip in a shoe, in that the stitches 'at 24 (Fig. 9) may pass through this reinforcing strip 22. It will be apparent from the foregoing description, in connection with the drawing, that my improved decorative piping strips may be produced with substantial savings as compared with the prior comparable piping strips, and may be incorporated in shoes, and other articles, to serve in the same manner and with the same decorative effects as the prior more expensive piping strips. Also, when a reinforcing fabric strip 22 is employed, as in the Figs. 2 and 3 embodiment, the fabric strip 22 substantially strengthens the stitched secure-' ment of the'piplng strip in a shoe, or other article.

It is intended that the patent shall cover by suitable expression in the appended claims whatever features of patentable novelty exist in the invention disclosed.
