ABSTRACT:
A hem former (16) for folding the margin of a sheet of material in preparation for sewing is mounted to the sewing bed (11) of a sewing machine (10). The hem former has a mounting plate (17), a guide plate (18) having a guide edge (23) and channels (24) extending therethrough, a support plate (22) having a front edge (28) reciprocally mounted upon the guide plate, and a guide cap (36). The guide cap has air nozzles (38) coupled to a supply of compressed air so as to generate an airstream directed beneath the front edge of the support plate and into the channels of the guide plate. The airstream urges the margin of material over the front edge of the support plate and into abutment with the guide edge.
