摘要:
A method of producing basic starting material for the manufacture of fastener tabs comprises the steps of: stretching a first sheet of elastic material in a first direction; applying a second and a third sheet of material onto respective opposite sides of the first sheet; fastening the three material sheets together in at least two mutually separated zones that extend parallel with each other in one direction perpendicular to the first direction; dividing the first sheet in each region between two zones along a line that lies between the zones, whereby the first sheet in each region between the zones contracts to a non-stretched state, and thereafter fastening the sheets together in each region between the zones.
