ABSTRACT:
In a papermachine coating or size press section a rope system is provided for feeding the web through the machine either initially or after a break. In an abrasive environment continuously running ropes can lead to excessive wear on the ropes. In the present invention a rope system for a papermachine has means independent of a papermachine for driving the ropes which may be stationary when not in use. The driving capacity of the rope system is such that during simultaneous operation of both the rope system and the coating or size press section, the rope system can operate at speeds greater than the section.
