CARD CLOTHING Filed April 2, 1964 United States Patent O 3,325,866 CARD CLOTHING Eugene V. Caille, South Barre, Mass., assignor t Associated Design & Mfg. Co., Inc., a corporation of Massachusetts Filed Apr. 2, 1964, Ser. No. 356,719 7 Ciaims. (Cl. 19-114) This invention relates to a novel type of card clothing, and the principal object of the invention resides in the provision of a heavy, preferably metallic, base wire in the form of a channel or the like which is easily provided With a filler member upon which are arranged spaced staples, each staple presenting two points.extending out of the open edge of the channel member, to form clothing some- What similar to metallic clothing but having separate inserted wire staples each With two points which are somewhat similar to the points in the filler types of card clothing. This provides for a greatly increased point population par square inch and also providing for a more economically manufactured card clothing which has teeth providing a certain amont of resilience and providing also for easy maintenance of the sharp points heretofore impossible with metallic wire, particularly With punched teeth. The new car-d clothing is easily cleaned and is self-stripping and does not tend to break or out the fibers.

The new wire teeth can be provided with a rake which is ordinarily desirable and this rake can be varied to any degree desired. This is donc merely by providing for the staples to be arranged on the filler at any angularity which is desired With respect thereto, and then the filler and assembled teeth are inserted in the channel, and the channel is squeezed at the sides thereof to hold the staples providing a strong, sturdy and substantially solid card clothing.

Another object of the invention resides in the provision of a novel card clothing construction as above described in which the filler can be formed with tufts so that in turn the card clothing has a desirable brushing action as well as the carding action, and in the present case this is done very economically. The new card clothing is perfectly cylindrical when mounted on the cards on the cylinder or roll even though there are dents or flat spots thereon, the base wire or channel providing for a film support for the points. The Wire can be mounted in spiral relation around the cylinder so that the various runs contact each other tightly and are practically self-locking being held in position, each by the other, as will be clear to those skilled in the art.

Other objects and advantages of the invention will appear hereinafier.

Reference is to be had to the accompanying drawings, in which:

FIG. 1 is a perspective view illustrating a form of the invention;

FIG. 2 =is an exploded view illustrating how the various parts are assembled;

FIG. 3 illustrates a filler having tufts or bristles therein;

FIG. 4 is a perspective view illustrating the base channel member;

FIG. 5 illustrates the filler member With the staples attached thereto at right angles with respect to the edges thereof;

FIG. 6 illustrates the filler with the teeth set at an angle, and

FIG. 7 illustrates a rubber or plastic member having a central core which can be used as a filler if desired.

Referring now to FIG. 1, a form of the finished clothing is illustrated. This consists first of a base wire or ferrule member in the form of a channel, this being illustrated generally by the reference numeral 10. This channel has the side walls 12 and 14 and a bottom wall 16, sec

FIG. 4. Mounted within the channel there are a series of mutually spaced staples. Each staple has a pair of legs 18, 18 and a member 20 connecting the same and closing the U, and it will be seen that these staples in general are in position within the channel 10 With the ends 22 of the staples extending outwardly from and forming the carding elements or points.

The staples are held in their generally parallel mutually spaced relationship in the channel by means of a filler member 24 and when the parts have been assembled, pressure can be applied at the exterior side walls 12 and 14 of the channel member to substantially permanently connect the parts together as shown in FIG. 1.

It is preferred that the channel member 10 be made of some strong material which can be extruded or folded in the form shown. Any other suitable material which can be formed and which when pressure is applied thereto will substantially permanently secure the staples to the filler member 24 can be utilized. The staples will of course -be made of the usual Wire of which card clothing points are made and the filler member 24 can be of metal, rubber, plastic, or any other suitable material. For instance, as shown in FIG. 7, a rubber or plastic tube 26 can be utilized and particularly if it is provided with a strong ocre 28 such as of metal, etc., it is perfectly possible to assemble the staples With respect to this filler and then into the channel as before.

One convenient way of assembling the parts is to first assemble the staples in their spaced relationship shown in FIG. 1 on the filler 24 as illustrated in FIG. 2. That is, the staples are arranged in parallel relation in the filler With the filler between the points in the areas 18 and the port-ions 20 thereof close to the bottom edge of the filler or in contact therewith. Any kind of adhesive can be used for this purpose and as shown in FIGS. 5 and 6 the staples will be retained in this position when being assembled within the channel 10. Once the assembly is done and pressure is applied as described, a substantially endless wire is provided which is strong and sturdy and substantially permanently connected as to the teeth. Thus the objects of the invention have been carried out, i.e., an extremely strong and rigid card clothing is provided in which however the teeth are inserted and can be ground and have all the advantages of wire teeth. Also the teeth can be inclined angularly with respect to the filler member as is indicated at 30 in FIG. 6, the filler member here hein-g indicated by the reference numeral 32. The showing in FIG. 5 is substantially the same as that shown in FIGS. 1 and 2.

As shown in FIG. 3, the filler can itself be formed for instance in the nature of a channel, and in this channel there can be provided a series of bristles or tufts. In this case the channel is indicated at 34 and the bristles or tufts at 36. Pressure can be applied to the sides of the channel 24 to hold the tufts in position and then the staples can be applied to the outside aspects of the filler member 34 just as previously described. In this case however the member 34 does not necessarily have to be in the form of a channel but may be in the form of a plurality -of parallel thin plates or wires assembled together and holding the bristles or tufts therebetween. Otherwise the construction and operation is exactly the same as before.

It will be noted that when it is desired to have angular points as in FIG. 6, it is not necessary to bend them so that there are knees involved, and stronger points are provided the fulcrum of pivot thereof being located in the bottom of the wire at the point 38 indicated in FIG. 6 rather than intermediate the ends thereof as is the usual case With leather foundations.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein 3 disclosed, otherwise than as set forth in the claims, but what I daim is:

1. Card clothing comprising an elongated strip in the general form of a channel having an open side, said channel forming a base, a filter disposed in said channel, a series of separate closely spaced wire staple elements, each wire staple element having a closed end joining a pair of spaced legs, the legs of the staple elements straddling the filler member, the elosed end of each staple element being held between the bottom of the channel and the edge of the filler that is adjacent the bottom of the channel, the legs of the staple elements extending outwardly from the channel at the open side thereof.

2. The card clothing recited in claim 1 wherein the channel closely engages and grasps the staple elements in the area. of the filler and holds the staples to the filler.

3. The card clothing recited in claim 1 Wherein the legs extend generally normal to the filler.

4. The card clothing reeited in claim 1 Wherein the legs extend generally normal to the filler and are parallel.

5. The card clothing recited in claim 1 wherein the legs extend at an incline With respect to the length of the filler in the channel.

6. The card clothing recited in claim 1 wherein the legs extend at an incline With respect to the length of the filter in the channel, said legs being straight and parallel.

7. Card clothing comprising an elongated strip in the shape of a channel forming a base, a filler disposed in said channel and held therein, said filler being closely engaged by the side portions of the channel and being located adjacent the bottom of the channel, a series of flexible tufted members mounted in the filler and extending outwardly from said channel, and a series of wire staples mounted on the filler and likewise extending from the channel t0 a greater degree than said tufts, each staple including spaced legs, the tufts appearing between the legs, and each staple having a closed portion extending generally about the filler and being held between the filler and the bottom of the channel.
