Abstract:
1. A process for producing patterned elastic sheetings, comprising: providing a pair of press rollers having opposite press surfaces respectively formed with at least one protrusion and at least one indentation opposite to said protrusion; providing a laminate which has at least two elastic sheet layers made of an elastomeric material, and at least one interface between said elastic sheet layers; placing said laminate between said press rollers and causing said protrusion to press said laminate into said indentation so as to deform said laminate until said interface is deformed; cutting said laminate along a cutting plane that passes between said press rollers and that passes through said laminate to divide said laminate into two parts; and causing said laminate to exit from said press rollers to return said laminate to a non-deformed state, wherein said interface deforms in a direction transverse to said cutting plane, and a pattern is formed in said laminate on two sides of said cutting plane after said laminate exits.
