Patent No. 1,816,416 to Baynard Willingham describes a knitting machine producing a continuous fabric by knitting together successive transverse plies of cotton roving. The product of that machine when out into lengths has come into extensive use in pads for the rollers of ironing machines, the product of the Willinghammachine being cut into widths capable of wrapping snugly around the roller. 'It will be understood that when so cut and wound, the plies run cir- It has been the practice, for the purpose of aiding in this wrapping of the rollers, to sew, or knit on one edge of the fabric produced in the machine as formed therein a strip of firm woven fabric, such as canvas, which, when the fabric is cut into lengths, may be first laid around the rollers to aid in anchoring the fabric. This is termed the lead cloth. For best results in uniting the plies, the distance between the knitting needles should be relatively close together, producing longitudinal rows of stitches, distant from each other of say, A", and'this has been the practice. It has been noticed, however, that in such pads they do not lie snugly on the roller. I have discovered that this can be obviated by increasing the distance between the rows of stitches fastening the lead cloth to the knitted fabric and making that distance greater than the distance between the stitches in the rest of the fabric. My invention, therefore, consists of a knitted fabric constituted by successive plies of I'OVil'lg and havin a lead cloth attached thereto, the stitches having the features cited above.

Referring to the accompanying drawings in which corresponding parts are designated by corresponding marks of reference:

V Figure 1 is a section through a roller having my improved pad wound thereon.

Figure 2 is a front view of a pad according to this invention, and

Figure 3 is a rear view thereof, the burlap backing being removed for the purposes of illustrating the nature of the stitch.

Figured is an enlarged view of one edge of a fabric as produced in my improved machine.

Figure 5 is a vertical fore and aft section of the knitting mechanism taken on lines X5-X5 of Figure 6 of such machine, and

Figure 6 is a front elevation of such knitting mechanism.

As shown in Figure l and in Figure 4, the main fabric consists of successive plies of roving a tied together and to a burlap backing b by a plurality of rows of stitches a a extending from one face 3 Claims. (01. 66192) of the plies to the other. A one edge sideis backed with a ribbon of canvas 5 1a, or other firm woven fabric, termed the lead cloth extending beyond the edges of the fabric while the balance of the width is backed only with the burlap, the sewing being accomplished as the successive plies are assembled.

As shown in Figures 2 and 3, the rows of' stitches a which tie the plies together and also fasten the canvas to the main fabric are farther apart than the rows of stitches a fastening merely the burlap to the main fabric. Thus at the edge we have stitches a fastenin the plies together and securing the canvas, and stitches a merely secure the plies together and to the burlap, the rows alternating. The width of the knitted fabric is'that proper, after suitable trimming of its edges, to wrap snugly around the iron ing roller 10 and for this purpose it may be cut into lengths proper for the lengths of the roller to which it is to be applied. The canvas lead cloth serves to make the initial wrap around the roller as shown in Figure 1.

To produce the article or pad such as just described I modify the structure shown in the Willingham patent by omitting the alternate front knitting needles 5 at one side of the machine and by feeding a ribbon of canvas in back of the rovings at such side and restricting the width of the burlap b so that except for a slight overlap with the canvas it covers only the rest of the knitted fabric. This is illustrated in Figures 5 and 6 in which the walls 2 form the ply guide for the plies of roving a'fed thereto. A strip of burlap b is fed down the guide against the rear walls thereof, it being supplied thereto from a roller 53* mounted on the shaft 53. Against the front and rear walls of the guide vertically reciprocate front and rear needles 5 and 6 projecting upwardly from the needle bars 4 and 3 which are alternately raised and lowered. Above the guide are mounted the thread guides IS, the mounting being such that such thread guide swings back and forth and is shifted laterally for each loop formed in the thread in the process of forming the stitches.

All of the above is as described in the said Willingham patent, but in addition to what is there shown I provide a shaft 54 carrying a roll of canvas 54a or other firmly woven fabric which is led down the guide between the burlap and the rear wall, the overlap being that desired.

When such a machine is operated a fabric will be formed consisting of successive plies of roving united together and to the backing structures needles are absent, have merely loops at the=front side of the knitted fabric the threadsthereof not; extending through the lead; cloth. This I find" tends to produce a smooth wrap around the ironing roller.

The machine above describedis shown-in my application filed Nov. 16, 1949, as a division here of, it being Serial No. 127,608.
