Abstract
A continuous loop waist band (10) is placed in edge alignment with a garment body (11), and the garment parts are stretched about spindles (19, 20, 21 and 23). The spindles are moved away from one another so as to stretch the aligned edges of the garment parts. The edges of the garment parts tend to curl when stretched, and an edge decurler (84) removes the curl from the stretched garment parts as the edges approach the sewing machine needle (26). Edge guide (102) maintains the plies of material in overlying contact so as to make sure the curls do not reappear in the garment parts as the parts approach the sewing machine.
