Abstract
An apparatus and method for cutting and sealing belt loop ends includes sealing and cutting members disposed on opposite sides of a length of fabric belt loop material formed wholly or partly of a heat sealable material. The sealing and cutting members are urged together in a scissor-like fashion to cut the strip across its width. The members are also configured to compress regions of the strip adjacent the cut ends. At least one of the sealing and cutting members is heated and the heat is transferred from the members to the compressed region adjacent the ends to melt or soften at least a portion of the meltable material. The melted or softened material merges or intermingles with the threads of the fabric in the compressed regions and upon cooling hardens to effect a seal of the belt loop at the cut ends. The seal substantially prevents the fabric from unraveling during subsequent laundering and wear. The invention may be used with a belt loop folding and feeding mechanism located adjacent a sewing station to prepare individual belt loops having sealed ends for being folded and then fed to the sewing station.
