Abstract: 715,154. Sewing; sewing - machines. AUTOSEAM, Ltd. Feb. 23, 1953 [March 5, 1952], No. 5753/52. Class 112 [Also in Group VIII] In joining fabrics composed wholly or substantially of synthetic thermoplastic such as nylon, cellulose acetate or polyethylene terephthalate, by sewing, the work is trimmed along the line of stitching and the trimmed edges are heat-sealed during the sewing operation. In lock-stitch sewing, simultaneous trimming and heatsealing is effected by means of a hot wire or like element positioned to engage the work at a predetermined distance from the line of stitching. In overedge sewing the work is trimmed by a cutting device, and the trimmed edges are passed into contact with a hot element. As shown, two layers of fabric 28 are fed beneath the presser foot 24 of a lock-stitch sewing machine and are sewn together by a needle 26 along a line 30. Simultaneously with this operation the work is trimmed by a hot, vertically disposed wire 2 which also heat seals the trimmed edges 29. The wire passes through a hole in the work table 1 offset from the needle hole and is mounted on a support 5 carried by the table. The latter is also provided with a parting blade which extends rearwardly from, and in line with, the wire and which serves to divert the off-cut 31 so that it will not become reunited with the trimmed edges 29. The table is also formed with slots on both sides of the needle hole, the serrated projections of the feed dog passing through these slots to co-operate with the forked' end of the presser foot. Current is supplied to the wire through electrical connections 12, 13 carried by the support 5. The wire is made of a rhodium platinum alloy and is heated to a temperature of from 500‹C to 750‹C by current at a potential of from 1.5 to 2.2 volts.
