IMPROVED METHOD AND APPARATUS FOR INCREMENTALLY STRETCHING ZERO STRAIN STRETCH LAMINATE WEB IN A NON-UNIFORM MANNER TO IMPART A VARYING DEGREE OF ELASTICITY THERETO

摘要

Improved Method for non uniformly Stretch Fabric laminated to a Zero Voltage to provide a variable level of Elasticity in the direction of stretching,To the point reached by this,Includes the steps of: (a) the Feeding of a Zero Pressure laminated Fabric comprising a First elastomeric Layer without Tensing fixed to a 2nd Layer without stress that comprendeuna Plot contUNI stretchable, but exhibits a Lower Elastic Recovery than the first layer.Between a pair of opposing surfaces pressure Applicators with tri dimensional complement each other in varying degree; and (b) The placement of portions of the laminated FabricZero Voltage between opposite surfaces of tri dimensional mentioned Applicators pressure non-uniform doing Progressive stretching between surfaces encastren ifIn a variable degree along their contact points with the laminated Fabric through which the 2nd Layer Stretch is permanently stretched in a variable level through stretchingProgressive non Uniform so that the laminated Fabric is extensible elasticamentede non uniform in the direction of stretching to the point reached by the sameOnce the forces are withdrawn from the process of laminated fabric of zero voltage.
