ABSTRACT:
Method and apparatus for shrinking a travelling web of fibrous material by transferring the web of fibrous material on a porous carrier web to a transfer web travelling at a lower velocity than the carrier web, curving the carrier web to a convex curvature toward the transfer web, at the transfer area, and employing a differential pressure to aid in the transfer of the web of fibrous material to the transfer web. Transversal shrinking is also accomplished by deviating the travel direction of the transfer web in the transfer area laterally at an acute angle from the travel direction of the carrier web. The fibrous material may also be transferred to a second transfer web which may also be at a lateral angle to effect transversal shrinking.
