Abstract:
A process for manufacturing a composite sheet capable of elastic stretch and contract in one direction, said process including the steps of:(a) providing a first web capable of elastic stretch and contraction and having a top surface and a bottom surface; (b) continuously feeding the first web along one direction; (c) extending the first web in the one direction within a range that permits elastic stretch and contraction of the first web; (d) allowing the extending first web to retract by an elastic contraction force of the web; (e) continuously feeding at least one second web along the one direction, said second web comprising a nonwoven fabric formed of fibers which are deposited in a layer without mechanical entanglement; (f) superimposing said at least one second web on at least one of said top surface and said bottom surface of the first web after said first web has been extended and refracted in steps (c) and (d); and (g) joining the first and second webs in an intermittent manner along the one direction.
