What is the Difference Between a Spreader Roller and an Anti-wrinkle Roller?

The difference between spreader roller and anti-wrinkle roller lies mainly in the application of the roller.

Spreader rollers and other devices are used in the converting process to stretch or widen webs as they flow through a machine. Spreader rollers use lateral, cross machine forces to increase the width of a web. Additionally, slitting machines use spreader rollers to separate slit widths post slitting process. Spreader rollers can include bowed rollers and nip type spreader systems.

Anti-wrinkle rollers and other devices are used in the converting process to remove wrinkles and there by prevent defects in products produced in web form. Anti-wrinkle rollers use lateral, cross machine forces to remove wrinkles. Anti-wrinkle rollers can include expanding surface rollers, bowed rollers, nip type, crowned rollers, concave rollers and grooved rollers.
