Abstract
An apparatus for flat seaming together a panti-hose half and a gusset has first and second carriers (16,18). The first carrier is moved from a loading station where a body portion of the panti-hose half is drawn on to the carrier, through an opening station where the body portion is opened along a preselected line extending from the waistband, into a seaming station. The second carrier is moved from the loading station where a gusset is loaded on to the carrier, to the seaming station. Each carrier has respective clamps (24,38), including an array of needles, which serve to grip the body portion and the gusset to their respective carriers. At the seaming station the free edges of the body portion, formed when the latter is opened at the opening station, and the free edge of the gusset are seamed together. Each carrier has a cam (78) which cooperates with a cam surface (80) to align the two carriers relative to one another, and means (74,84) which rotate the two carriers about their central axes to bring successive portions of the free edges of the body portion and gusset together at the seaming station to enable these edges to be sealed together.
