CARD CLOTHING FOUNDATION Filed June 8, 1928 I firberz" Mfiiey @y am:
Patented Aug. 26, 1930 PATENT OFFICE HERBERT IDGLEY, 01' WORCESTER, MASSACHUSETTS CARD-CLOTHING I'OUNDATIdN This invention relates to card clothing as used in carding engines and other textile machines. Such card clothing was formerly made most largely on a leather foundation. At the present time the use of fabric foundations is quite general, due in part to the increasing cost of leather.
An essential characteristic of a satisfactory card clothing foundation is its ability to maintain its length substantially unchanged, and to resist stretching while in use. If the foundation stretches, the card clothing becomes loose on the carding rolls, and it is necessary to remove the rolls from the machine and to rewind .the card clothing on the roll. This is a troublesome and expensive operation and also involves loss of production on the machine.
Another essential characteristic of a satisfactory card clothing foundation is its ability to firmly support and retain the card wires inserted therein.
It is the general object of my invention to provide an improved construction of card clothing'foundation so devised that it will effectively resist longitudinal stretching, and that it will firmly support and retain the inserted card wires.
A further object is to provide a reinforcing layer of fabric of improved construction in a card clothing foundation.
' Further features of my invention will be hereinafter described and more particularly ble foundation.
In the drawings, I have shown the foundation as comprising a front facing member 10, a back facing member 11, a stiffening layer Application and June a, 1928. Serial no. asapaa.
12, and a reinforcing layer 14. The front and back facing layers may be of any suitable woven fabric, such as is commonly used in the manufacture of fabric card clothing foundations. The stiffening layer 12 is also of the usual construction, and is preferably formed of woolen threads interwoven with stuffer warps to form a relatively thick fabric, giving body to the foundation. This stiffening layer is'preferably thoroughly impregnated as usual with some cementitious material, by which its stiffness is increased.
The reinforced layer 14 is of an improved and much more satisfactory construction than that found in fabric card clothing foundations as previously manufactured. The layer 14 is formed from a special woven fabric, having the threads 20 which extend crosswise of the fabric of relatively small size, and having the threads 22 which extend lengthwise of the foundation of relatively large size, and preferably inserted in pairs in the fabric as indicated in Fig. 1.
The light threads 20 commonly form the weft threads and the heavier threads 22 commonly form the warp threads. The warp threads 22 are not only much heavier than the weft threads 20, but they are also formed of high-grade, long-staple cotton, such as Sea-Island cotton, which contributes very great tensile strength to the fabric.
The card wires 30 are formed as the usual U-shaped staples and are driven through the foundation as indicated in the drawings.
In fabric foundations as previously used, the portion corresponding to the layer 14 has commonly been formed of a series of linen cords, extending lengthwise of the fabric and secured side-by-side merely by cementing the cords together, there ein no cross-weaving of this portion of the fabric.
My improved foundation has been found in actual test to possess very important advantages over the type of foundation previously used. It is found that my improved foundation may be used twice as long or even longer before stretching thereof will necessitate rewinding, and it is also found that the cross weavin of the reinforcing layer 14 affords additional support to the card wires 30 over that obtained from the longitudinal cores previously used, so that the wires do not become loosened as easily.
The several layers of my improved foundation may be secured together in any usual manner, as by cementing or stitching.
Having described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is A card clothing foundation formed of a. plurality of woven fabric layers secured toether and comprising front and back faclng fabrics, a. relatively thick intermediate woven body layer impregnated with cementitious material, and a reinforcing layer of woven fabric affording longitudinal strength for said foundation, said reinforcing fabric comprising relatively light weft threads ex tending crosswise of the foundation, and relatively strong and heavy warp threads extending lengthwise of the foundation, and said warp threads being inserted in pairs in said reinforcing fabric.
In testmony whereof I have hereunto affixed my signature.
