1,006,962. Sewing machines. MASTER SEW CONTROL CORPORATION. Feb. 14,1964 [March 15,1963], No. 6306/64. Heading D1G. A rectangle of cloth is placed on a conveyer belt, and is then so positioned that an edge thereof extends over an edge of the conveyer belt, the latter feeding the cloth through a hemming machine, the cloth being simultaneously held down upon the conveyer belt, to form a line of duplicater marked stitching parallel to the edge of the belt, and the stitch chain is severed as the hemmed edge leaves the machine. As described, the rectangular piece of cloth is cut from a roll of cloth the two sides of which are initially hemmed, and the other two sides of the piece are hemmed in succession, to form a handkerchief, while the piece travels on the conveyer belt. An endless conveyer belt 15 is arranged with its upper run supported on a table 18. Rectangles of cloth having two opposite sides initially hemmed are laid on belt 15 with the unhemmed edges parallel to the edges of the latter. An edgepositioning means 25 moves a workpiece laterally till its right hand edge overlaps the edge of belt 15 by a predetermined amount. Said edge of the workpiece is then trimmed by cutting means 280, and is next hemmed by a sewing machine 200 while being simultaneously held down by means 175, the stitch chain finally being severed by means 325, and any tail at the end of the hem being removed by cutting means 350. The left hand edge is then similarly hemmed while the workpiece travels on the belt. Edge-positioning means 25, Figs. 1 and 3, comprises a carriage 26 movable on tracks 70 in the direction of belt movement. A pusher bar 27, adapted to move the work transversely, has work-engaging feet 30, and is rigid at its respective ends with rods 28, 29, the upper ends of which carry rollers 127 movable on the ends of levers 31, 32 pivoted at 33, 34 to carriage 26. The other ends of levers 31, 32 are rigid with a bar 37 carrying a collar 40 spring-biased into engagement with a ...
