Title:

MATTRESS BORDER PRODUCTION SYSTEM

Document Type and Number:

WIPO Patent Application WO2002075031

Kind Code:

A3

Abstract:

A machine for automatically producing a mattress border with handles sewn to the border material. Border material 16 is pre-fed and handle material 33 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 36. 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 folded 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 90 is translated separately from the carriage which travels in the sew pattern, to position the handle under the sewing needle.
