Title:
SEAL JAW MODULES FOR RECLOSE BAG MODIFICATION TO VERTICAL FORM, FILL, AND SEAL PACKAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO2001017857
Kind Code:
B1
Abstract:
A self-aligning zipper seal module adapted for quick change-out in a sealing carriage. The zipper seal module allows for a quick modification of a sealing carriage in order to accommodate different package dimensions. The module is stored and is installed in a closed and aligned position by an alignining handle (576). The module is easily installed or removed with a single tool and is designed to reduce the potential for operator injury by isolation from heat source and by virtue of the aligning handle. The various sealing facings of the module are oriented to equalize pressure on the facings during sealing and increase stripping efficiency. The zipper sealing facings (440, 442) incorporate a novel insert design (798), thereby eliminating the need for stocking different sized facings to accommodate various bag widths. A return module of similar design is used to quickly return the sealing carriage to a standard configuration.
