Abstract

A zipper sealer machine for use with form, fill and seal machines and the method for bonding strips of reclosable fastener material strip fastener material to the film of a form fill and seal machine. The zipper sealer machine is adapted to be mounted within in the form, fill and seal machine and coordinate with the components of the form, fill and seal machine such as its film control mechanism. The zipper sealer machine includes a substantially symmetrically formed rotor having a pair of outer edges. Reclosable fastener material strip fastener material is fed to an outer edge of the rotor and cut to length. The cutting process also fuses the cut ends of the reclosable fastener material strip fastener material . The rotor is rotated 180 degrees, which locates the strip of reclosable fastener material strip fastener material adjacent to the film course at which it is bonded to the film. The reclosable fastener material strip fastener material cutting and fusing device does not utilize a cutting knife and thus requires less service. The zipper sealer machine includes an adjustable film control roll that allows fine tuning of the operation to assure that the reclosable fastener material strip is bonded in the proper relationship to the printout on the film.
