ABSTRACT:
An apparatus and process for making an elastic composite sheet including a pair of rolls adapted to bond respective surfaces of a inelastic sheet and a elastic sheet and fed together into a nip of the rolls. One of the rolls is formed with ridges while the other roll is formed with grooves and the ridges are engaged with the grooves with spaces left between surfaces of the ridges and the grooves to form the inelastic sheet on its surface with stripe-like crests and flat troughs each defined between each pair of the adjacent crests; and the inelastic sheet is bonded along its troughs to the surface of the elastic sheet.
