摘要： A method of fabricating reclosable bags comprising: disposing a releasably engaged closure between a first and a second bag film portions, the closure including a loop-engageable fastener strip comprising an array of loop-engageable fastener elements integrally molded with a sheet-form resin substrate, and a loop strip comprising a plurality of loops carried on a sheet-form resin base; and applying energy to bond the resin substrate of the loop-engageable fastener strip to the first bag film portion and to bond the resin base of the loop strip to the second bag film portion; wherein the loop-engageable fastener strip is not bonded to the loop strip when the energy is applied.

摘要： A method and apparatus for producing a fastener product having a multiplicity of fastener elements extending from a sheet-form material. Molten resin is extruded through an extrusion nozzle and gas is introduced into the resin within the extruder to provide an interrupted flow of resin from the nozzle to deposit discrete regions of molten resin onto the sheet-form material. The discrete regions of molten resin are spread apart along a longitudinal direction of the sheet-form material. The molten resin is permanently bonded to the sheet-form material, and a multiplicity of fastener elements are molded from each discrete region of resin.
