CARD CLOTHING Filed Dec. 7, 1961 INVENTOR EUGENE V. CAILLE ATTORNEY United States Patent 3,118,185 CARD CLOTHENG Eugene Victor Caille, 3 Vernon St, South Barre, Mass. Filed Dec. 7, 1961, Ser. No. 157,653 8 Claims. (Cl. 19-114) This invention relates to a completely novel type of card clothing. In general there are two main types of continuous card clothing, fillet and metallic. Each one of these types of card clothing has well known advantages and disadvantages as well as certain definite restrict1ons as to the point population per square inch, and it is the general object of the present invention to provide a card clothing which combines the good features of both fillet and metallic (garnet) while at the same time avoidmg all of the disadvantages of both, and also at the same time providing for a greatly increased point population per square inch. Whereas the densest fillet point population per square inch is in the nature of 860 points per square inch and that of the metallic wire is a maximum of 580 points per square inch, in the present instance it is possible to provide up to 2,000 points per square inch, and of course as is generally recognized the greater number of points, the better the quality of the stock and the greater the production.

The present invention includes the provision of card clothing in the general nature of a metallic base wire somewhat similar to metallic clothing but instead or" integral teeth the new clothing has separate inserted wire points which are somewhat similar to the points in the fillet type of card clothing but are not staples, thus providing for a little give or resilience in the teeth which is impossible with the metallic wire punched teeth, and providing for the maintenance of the sharp points in the new clothing which is impossible in the metallic wire. The new wire is resilient with self-stripping properties not possible in the metallic wire and of course as is well known the punched edges of the metallic points tend to break or cut the fibers which does not occur of course with the round wire teeth.

Furthermore the new wire teeth can be provided with a forward rake which is ordinarily desirable and this rake can be varied to any degree desired. The sides of the base wire on which the separate teeth are mounted are more or less naturally self-locking, contacting each other tightly around the cylinder or roll and being held in position thereby although it is possible with side embossing as a straight-lined knurl or the like to bind and lock the courses of the base wire together.

There are a great many other advantages in the present invention among which is the fact that if there are dents or flat spots on the cylinder or roll, it is of course impossible to grind off the points of garnet wire teeth in order to accommodate the same, but it is possible to do it with the new wire so as to provide a perfectly cylindrical point surface, even though there are dents or flats on the roll, and of course with dents or flats on the roll or cylinder, the fillet clothing does not have a firm support.

The invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly set forth in the appended claims.

Reference is to be had to the accompanying drawings, in which FIG. 1 is a View in side elevation illustrating the new card clothing;

FIG. 2 is a section on line 22 of FIG. 1;

FIG. 3 is a plan View; and

FIG. 4 illustrates the card clothing strip prior to formation.

The basis of the present invention essentially is the fact that the base supporting wire is made of metal like a garnet wire but instead of having punched or cut teeth integral therewith as in the garnet wire, the teeth in the present case are made of round or other shaped wire and are formed separately and of different material should this be desired and are secured to the base wire. By this means it will be seen that it is possible to place the wires in side-by-side contacting relation if this should be desired as completely opposed to any possiblility of this in either fillet or garnet wire points.

A layer or layers of some flexible base material it as paper, tape, plastic, etc. is used to mount the individual wire points 12. This is then applied to an elongated strip of metal which is somewhat tlexible and resilient and this strip is longitudinally bent over upon itself approximately upon lines which are indicated at 14 and 16 (FIG. 4), the folds of course including the wire points 12 as well as the layers in).

This results in a formation similar to that shown in PEG. 2. The metal sheet is indicated generally by the reference numeral at 18 and the folds are appropriately labeled at 14 and 16 to coincide in general with the equivalent lines in FIG. 4. It will be noted that the fold at 16 is relatively broad. The folding over results in an interior end layer or lamination 2t, of the metal sheet 13, connected as by the bend at 14 with an outer sheet or layer 22, and an opposite outer layer 24 connected to that at 22 by the relatively broad told at 16. Or" course the wires 12 are bent in the same way providing internal end portions 26, intermediate bent portions 23 and generally straight portions at 39 which extent outwardly of the metallic sheet fold construction forming the points 32.

The points 32 may be provided with a forward rake if desired, or they may be straight.

It will be seen that this construction provides for very closely spaced wire points 32 or for any spacing needed. The points may be round or oval or have any other section which may be desired, and they are of course securely and permanently locked in position by reason of the interwound construction as exemplified particularly by the terminal portion 26 of the wires 12 in cooperation with the internal central folded-in portion as of the sheet metal material. The degree of pressure applied to the opposite sides of the base metal 18 determines the possible indentation of the metal as shown in FIG. 3, and it will be appreciated that the wire teeth are held ex remely firmly and although they themselves are resilient and have qualities of self-cleaning as explained above, nevertheless they will not move to any appreciable extent within the base wire member 18. The gummed paper ai fords a certain degree of freedom of action which is in some cases desirable.

It will be seen too that the exterior side walls of the base metal '18 can be embossed as for instance by vertical or inclined grooves or ridges or the like, and when this wire is wound on a roll or cylinder, the same will therefore be securely locked in position against any kind of disturbance. However, such embossing is not always necessary and various other locking means might be utilized in order to hold the courses or winds of the base wire member together.

it is believed that it will be seen that all the objects of the invention have been carried out and that the present card clothing has all the advantages of both fillet and garnet wire without any of the disadvantages of either one. The wire members can be placed in actual contacting relation if desired, and by this means many more points per square inch can be provided, whereas in fillet card clothing it is impossible to put the wires so close together as the punched holes in the foundation would cause the foundation to be so weak as to be useless; and of course the conventional punched teeth in garnet wire cannot be punched in any such frequency. The Wire is very easily handled and as will be clear to those skilled in the art it can be ground Whenever desired While still in position on the cylinder or roll, this being impossible with the ordinary garnet Wire.

Havin thus described my invention and the advantages thereof, 1 do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. Card clothing comprising an elongated base in strip form, a series of Wire tooth elements mounted on the strip and extending therefrom generally transversely thereto, and interengaging means on the base and each tooth holding the teeth to the base, the interengaging means including complementary hook-like portions on the base and on each tooth.

2. Card clothing comprising an elongated strip forming a generally flat base and a series of Wire elements mounted thereon, said Wire elements extending laterally from the base at a side edge thereof and presenting a series of points extending therefrom at said side edge, and means securing each tooth to the base.

3. Card clothing comprising an elongated strip of metal forming a base and a series of wire elements mounted thereon and secured thereto, said wire elements extending from the base Wire and presenting a serie of points extending therefrom at an edge thereof, each Wire element having a reversed end portion held in the base, and means in the base receiving, holding, and concealing the reversed ends of the Wire elements.

4. Card clothing comprising a base strip and a series of separate Wide teeth mounted thereon, said teeth having 4 reversely extending terminal portions embraced by reversely arranged terminal edge portions of the base strip.

5. Metallic card clothing comprising a relatively heavy elongated Wire base member longitudinally folded on itself and a series of separate closely spaced relatively light Wire teeth mounted thereon and extending laterally therefrom each tooth having a portion engaged in the fold and held therein and thereby.

6. Metallic card clothing comprising a relatively heavy elongated wire base member and a series of separate closely spaced relatively light Wire teeth mounted thereon and extending laterally therefrom, said teeth having hooklike terminal portions embedded in the base member.

7. Card clothin comprising a relatively heavy elongated base member and a series of separate closely spaced relatively light wire teeth mounted thereon and extending laterally therefrom, said base member being longitudinally folded on itself to form connected spaced layers forming a hook-like passage, and the teeth including terminal portions in the passage and interengaged with the layers of the base member.
