Abstract

Abstract A border panel manufacturing machine having 1st and 2nd sewing heads mounted for contemporaneous transverse right and left movement over cross traverses, each of which is horizontally planar, straight and relatively adjustable in size. In one case, the 1st head sews along a conventional square cut zigzag path extending completely across a 1st strip-like border panel component assembly of full width while the 2nd head sews along a similar square cut path extending completely across a 2nd completely separate border component panel assembly, the full width of which is the same as or different from the full width of the 1st panel assembly. In another case, both heads sew along similar square cut zigzag paths respectively extending completely across the width of separate ''''left'''' and ''''right'''' halves of one border panel component assembly while both heads cooperate with each other to sew, to said separate left and right halves, the left and right borders or flanges of a zipper strip arranged between them. This procedure integrates said panel assemblies into one single border panel having a centrally disposed zipper. Naturally, either head of the machine can also be used to sew a single border panel assembly while the other head remains idle. Provision is also made: to clamp the work or unclamp it contemporaneously on both front and rear sides of the sewing zone and to clamp it only on the front side when desired; and to adjust the size and the position of each sewing head reciprocation independently of the other.
