Abstract
For aligning and stretching a travelling web or foil (2), a pair of stretching rollers (21,22) have surfaces formed to give a good frictional contact with the web and shaped to give a stretching effect. The web also passes under a large diameter drum with its surface formed by strips or slats (34), which can be extended outwards to correct the alignment of the web. The stretching rollers can also be adjusted in the opposite direction to the adjustment of the drum slats. In alternative designs, the stretching rollers can be followed by a set of e.g. three aligning rollers of similar diameter to the other rollers. The aligning rollers can be tilted about a vertical axis at right angles to the belt travel and the stretching rollers adjusted longitudinally.
