FIELD: pull-tab for non-woven elastic fastener and elastic film attached to each first side of fastener member. ^ SUBSTANCE: pull-tab of non-woven elastic laminate consists of first and second adjoining members of non-woven fastener and elastic film produced by coextrusion process and fixed to first side of fastener member. First face side of each fastener member consists of first portion coated with pressure-sensitive adhesive, and second portion adjoining said first portion. Coextruded elastic film has two first zones, each comprising at least one non-elastic section, and second zone provided between two first zones and comprising at least one elastic section. Two first opposite zones are fixed at two portions coated with adhesive glued upon pressing of two members together correspondingly so that second portions of two adjoining fastener members, free of adhesive, contact with their face sides with at least part of second zone of coextruded elastic film. Thickness of all the layers is such that total non-uniformity of thickness throughout the entire area of pull-tab of fastener is less than 50%. ^ EFFECT: simplified manufacture of article and provision for avoiding contacting with adhesive during winding of material into roll. ^ 10 cl, 5 dwg, 1 tbl, 2 ex |
