Expanding surface type anti-wrinkle rolls utilize a roller surface that grows linearly in the cross machine direction. Examples of expanding surface rolls include:
Because most of the spreading action of these anti-wrinkle rolls takes place on the roll face, one excellent application for expanding surface type anti-wrinkle rolls is anywhere in your machine that is very "tight" with other rollers. In other words, spreader rolls like bowed rolls require a long lead-in distance (unsupported web distance) because most of the spreading action bowed rolls deliver takes place in the entry span to the bowed roll, so bowed rolls generally require a lot of space in your machine in order to operate properly. Generally, expanding surface type anti-wrinkle rolls can directly replace existing idler rolls, making mounting extremely easy with little or no modification.
