ABSTRACT:
Stretched elastic strands and a continuous sheet are fed concurrently toward a diaper assembly station on the way to which quick setting adhesive is applied periodically to zones in one and slower setting adhesive is applied alternately periodically zones in the other. Diapers assembled as a continuous web at the station are ultimately severed at which time the quick setting adhesive zones are set already and impart elasticity to the crotch region of the diapers. The zones on the strands that are tentatively adhered to the sheet with slow setting adhesive contract gradually into the diaper along the straight adhesive lines and then they set.
