Abstract

A combination blowbox/saveall system (20) and method for use in conjunction with a pick-up roll (22) of a papermachine (18) around which a carrier fabric (26) and running web (28) are moved in concert utilizes a blowbox section (40) for directing air from a source generally away from the surface of the carrier fabric opposite the web to reduce the likelihood of separation of the web from the carrier fabric and a saveall section (60) joined to the blowbox section in a single device. During operation of the system, at least a portion of the air which is directed away from the carrier fabric by the blowbox section for the purpose of preventing separation of the web and fabric downstream of the pick-up roll is used to dislodge water droplets (72) and other contaminants from the surface of the pick-up roll, and these droplets and contaminants are collected within the saveall section for disposal.
