Abstract: Heat is supplied to elements of a web processing system to resist adhesive contamination by buildup. A variety of heat sources can be used on a variety of web handling structures, such as rollers, idlers, conveyors, vacuum belts, or any other place where adhesive accumulation is undesired.

Abstract: Provided are methods and apparatus for transporting either an entire web or discrete components of disposable products. The invention is a means of conveying the web or diaper components down the machine using mechanical forces to grip the nonwoven web and transfer it from one belt or roll to another without or reducing added vacuum. There is a carrier nonwoven web that goes down the length of the machine and other substrates are added on top of this. Methods and apparatus are disclosed to provide sufficient gripping to allow transport of diaper components through the fabrication process. Securing and releasing forces are supplied so that the components can be retained at some points and released at others.

Abstract: A corrosion protected knife and anvil system is disclosed. A source of lubricating fluid is provided to a lubricating fluid distribution mechanism, coupled to both a knife blade and a salt bridge and an associated sacrificial anode. The sacrificial anode is consumed in order to protect corrosion on a rotating knife blade, which intermittently contacts both an associated anvil in order to cut material used in making disposable products, and the source of lubricating fluid. A knife holder holds a knife which is corrosion protected by an impressed current anode.
