Abstract
Abstract In a broad-drawing roll for moving webs of paper or the like, including a plurality of individual roll sections defining an arcuate curve to spread the web, the improvement which comprises a plurality of supporting bearings provided between the individual roll sections, said bearings being adjustable selectively and independently of one another and thereby determining the degree of curvature defined by said roll sections. Each roll section is mounted in freely rotatable fashion on its own shaft of substantially the same length as the section. Bearings, comprising two halves meeting along a line diametrically of the shaft, occupy substantially the full small space between adjacent roll sections.
