Abstract (en)
[origin: EP1026317A2] The calender assembly has a stack of rollers forming nips between them to process a web. A moving web guide (11) in on at least one side of the stacked rollers (2) which can be fixed in at least one web insertion position. The web guide (11) is fixed in a park position where it does not shroud any of the roller nips (5,25,27). The web guide (11) is attached to a moving platform (12) at one side of the roller stack (2). Position switches are along the movement path (13), at the web insertion positions, linked to a drive control. The web guide has a guide surface structure (15,16) in a variable shape using a flat surface (21) and deflection surfaces (15,16) moving out of it on swing levers (17,18). The deflection surface (15,16) can be on a push unit across the direction of movement. The guide surface structure has at least one tongue which can be pushed as far as the roller stack (2). The web guide (11) has at least one grip head which, in the first movement phase, moves from the roller stack (2) at right angles to it. In the second movement phase, it moves parallel to the rollers and, in a third phase, moves towards the rollers (2) at right angles to them. The grip head has a suction and/or blower unit. The grip head can rotate by 180 degrees round an axis, parallel to the axes of the rollers (3,4). The grip head grasps the web (8) at the side. The rollers are in an angled stack (2).
