摘要:
Disclosed herein is a machine with which it is possible to effect the stitching between the vamp and the upper part of the shoe and thus to create the upper border on "moccasin" type shoes, in particular, those of the "tubular moccasin" type, which utilize a continuous end sealed vamp. An improved ruffling of the vamp prior to attachment to the upper portion is accomplished by synchronized ruffling jaws. The machine operates in a fully automatic fashion and has the capability to vary the length of the stitch and of the ruffle of the vamp in the region of the upper part of the shoe.
摘要:
A machine for sewing together two workpiece parts having edges of equal or unequal length by using a bead seam, especially for joining together the edge of a vamp and the shorter edge of a plug of a true moccasin shoe, so that the length of the plug matches that of the longer edge of the vamp, in only one operation. The bead seam forming device essentially consists of a folding finger acting in front of the needle of the sewing machine and in synchronous driving connection with the needle; several machines are described which are provided with different bead seam forming devices.
