摘要：Mandrel device which includes a support surface defined by an endless belt 37 which passes around two support drums 36 whose separation can be varied selectively, and a belt guide assembly 38, 39 which preferably deflects the belt 37 so that it follows a path extending towards the inside of the support drums 38, giving rise to a peripheral discontinuity in the support surface of the device. The belt guide assembly may also include a roller 39 for keeping the belt under tension and, optionally, a cutting device. <IMAGE>
