摘要 PCT No. PCT/EP95/03477 Sec. 371 Date Aug. 14, 1997 Sec. 102(e) Date Aug. 14, 1997 PCT Filed Sep. 5, 1995 PCT Pub. No. WO96/07608 PCT Pub. Date Mar. 14, 1996A winding machine for winding up webs, possibly longitudinally divided webs, and preferably paper webs. The winding machine comprises two support rollers which support, in a winding bed, the roll to be produced and of which possibly one or both comprise casings which can be deformed, preferably to different degrees. During the winding process, the web running through the spacer gap between the two support rollers partially wraps around one of the two support rollers. The winding machine further comprises a space delimited by the two support rollers, the partly formed roll, and this space has sealed closures on its ends and a sealed closure below the spacer gap between the two support rollers. Finally, the winding machine generates excess pressure in this space in order to balance the inherent weight of the roll. The sealed closure below the spacer gap comprises a pivotable side wall which extends substantially over the entire maximum web width of the roll to be produced and whose pivot axis extends approximately parallel to the support rollers axes. The side wall can be pivoted sealingly towards the support roller, around which the web is wrapped, while leaving free a web passage gap for the winding process. The side wall can be moved, in particular pivoted, away from the support roller, around which the web is wrapped, for the introduction of the web.
