Abstract
A roll former has a plurality of paired die assemblies spaced apart across a midline of the roll former, and a web of material is fed through the roll former along the midline for operations by the die assemblies. The spacing between each pair of die assemblies is uniformly adjustable by way of mounting the die assemblies on collector plates movable toward and away from each other by linear actuators such as jack screws. Smoothness of movement is enhanced by supporting the collector plates only on the linear actuators. Precision of positioning is enhanced by using jack screws as the linear actuators.
