Abstract
A system and method for transferring a nonwoven web in a wet papermaking process to a fabric is disclosed. The system includes a vacuum shoe that operates in conjunction with a transfer shoe. The vacuum shoe is contacted against a carrier fabric which is designed to receive the nonwoven web. The transfer shoe, on the other hand, is configured to contact a transfer fabric from which the web is transferred. The transfer shoe includes an air nozzle which contacts the nonwoven web with a pressurized gas as the web is drawn towards the vacuum shoe. The system of the present invention is particularly well suited to processing lower basis weight webs and can be used in rush transfer processes.
