Abstract
Disclosed is a rotary apparatus suitable for processing and working a web or sheet of materials such as plastic films, non-woven substrates, metal foils, paper, diaper cores and the like. Such apparatus includes counter-rotating anvil and tool rolls through which the web or sheet of material to be worked is fed. The tool roll includes at least one processing tool for working the web or sheet of material. The force of the tool on the web or sheet being worked is regulated by a force applied to the processing tool or the anvil surface of the anvil roll by a force-transmitting chamber which includes a fluid. The force applied is adjusted by altering the pressure of the fluid within the force-transmitting chamber.
