Abstract
In the process for mounting a slide fastener segment or slide fastener near the opposing edges of two pieces of material, particularly on a slit in a piece of clothing, a slide fastener strip, the slide fastener segment or the slide fastener and the pieces of material are fed to the sewing stations of a two needle sewing machine. The pieces of material in the region between the sewing stations are positioned to form a gap and are curved so that a portion of each hangs substantially vertically from two fold edges or creases in an intervening space between both of the sewing stations. Both slide fastener halves of the open slide fastener segment or the open slide fastener are sewn on from above on the horizontal portion of the pieces of the material along the fold edges. Apparatuses for performing the process according to my invention are also described.
