ABSTRACT:
A process for producing patterned elastic sheetings comprises the steps of providing a pair of press rollers having opposite press surfaces respectively formed with at least one protrusion and one indentation, providing a laminate having at least two elastic sheet layers and one interface, placing the laminate between the rollers and causing the protrusion to press the laminate into the indentation so as to deform the laminate until the interface is deformed, cutting the laminate along a cutting plane that passes between the rollers and that passes through the laminate to divide the laminate into two parts, and causing the laminate to exit from the rollers to return the laminate to a non-deformed state. The interface deforms in a direction transverse to the cutting plane, and a pattern is formed in the laminate on two sides of the cutting plane after the laminate exits.
