Arrangement for pressing two parallel-axis, mutually drawable rollers in a device for producing and/or treating a web of material

摘要

A parallel double-roller (14, 16) assembly spreads a coating of liquid or paste to a web (10) of paper or carton. The assembly has a jack (26) which applies a converging force to the rollers and a sensor (36) determining the force. The sensor (36) is esp. positioned in the compression force transmission system between the jack and rollers. The system has two or more compression transmission paths each incorporating a pressure sensor. The compression applied by each jack is individually variable. One of the rollers is fixed but rotates within a machine frame. The second roller rotates within the frame but moves in response to pressure from the jack (26) applied through a lever.
