ABSTRACT:
Apparatus and method for forming hemmed curtains including advancing a continuous length of fabric while simultaneously carrying adhesive filaments across the fabric, then stopping the fabric and performing a series of operations thereon at an operating station, including cutting the fabric along a transverse line adjacent the adhesive filaments, then folding the fabric end pieces with a double folded hem extending over the adhesive filaments and with the cut edge of the fabric contained within the fold so as not to be exposed, then heating the adhesive filaments to melt them and thereby secure the folded hems in place, and finally advancing the fabric again to present another part thereof for similar processing. Preferably, two adhesive filaments are carried across one of the fabric pieces whereby the folded hem thereof will be secured in place along spaced parallel securing lines so as to provide a curtain rod pocket in such hem.
