WINDING MACHINE

摘要

A winding machine for winding webs that may be longitudinally slit, preferably paper webs (PB), has two support rollers (TW1 and TW2) that carry the roll being produced (R; R'; R''; R''') in a winding bed. Both support rollers have elastic casings (M1 and M2) which are however deformable to a different extent. One of the support rollers is partially surrounded by the web during winding. In order to further optimise the winding quality, even in the case of heavy rolls, the support roller subjected to the highest total load, that results both from static and dynamic loads during winding, has the most elastically deformable casing (M1). Such a winding machine is preferably developed so that the space (DR) delimited by both support rollers (TW1 and TW2) and the already partially produced roll (R) is sealed as much as possible at its ends and from below. An overpressure can be generated in the space (DR) for relieving the inherent weight of the roll (R). This combination of measures substantially prevents undesirable inclusion of air.
