Abstract
The externally held, adjustable width spreader for tubular material (1) present in a flat state is provided with two spreading and guiding units (2, 3) which are to be arranged next to one another in the interior of the tubular material. The spreading and guide units are each provided with an endless transporting belt (4) which extends along their outer guide faces and is exposed there. The transporting belts (4) and in releasable operating engagement with feed rollers (8, 9, 10, 11) disposed on the exterior of the tubular material (1) passing through. To be able to unimpededly change the width of the spreader externally during the passage of tubular material (1), each one of the two guide units (2, 3) is held in its position by means of externally engaging support rollers (12-15) whose axes of rotation (16) are perpendicular to the direction of passage of the tubular material (1) and which are in releasable engagement with counterrollers (17-20) which are rotatably mounted in the guide units (2, 3) and are supported thereby. To vary the spreading width of the spreader, the feed and support rollers (8-11, 12-15) associated with the one guide unit (2) are mounted in a carriage (21) so as to be jointly displaceable in the spreading direction (B).
