ABSTRACT:
Fibres in a web are redistributed by ultrasonic vibration between two rigid members, for example to unite two webs together or to create a pattern of fibre orientation and fibre density; and preferably one of the members is a forwarding roll which forwards the web into a zone of increasing vibration in which fibres are bonded after redistribution.
