ABSTRACT:
A collapsing frame for collapsing a moving tube of plastic material from a circular cross section to a flattened form has a pair of frame members positionable on diametrically opposite sides of the tube to converge towards each other in the direction of movement of the tube so as to collapse the tube by engagement of the tube therewith. Each frame member has mounted thereon for engagement by the tube a series of longitudinally spaced roller assemblies mounted for free rotation about axes substantially transverse to the direction of movement of the tube. Each roller assembly comprises at least one rotatable roller having a peripheral surface oriented to tend to move the tube at an outwardly inclined angle to the direction of movement of the tube.
