Abstract

A machine for automatically producing a mattress border with handles sewn to the border material. Border material is pre-fed from a selected spool, screened for splice avoidance and measured. Handle material is fed from a selected spool mounted in a multiple handle material spool magazine mounted on rails, fed into a handle folding assembly, and cut to length. Ends of the handle material are folded under by the handle folding assembly and the handle then transferred in a folded condition from the handle folding assembly to a correct position on the border material. A double frame handle press holds each folded end of the handle material in place as each end is maneuvered under a sewing head needle to apply a stitch pattern to secure the folded ends to the border material. The double frame handle press is translated separately from the carriage assembly which travels in the sew pattern, to position the other end of the handle under the sewing needle.
