Embodiment 100

[0039] Embodiment 100 also includes a third roller 12 supported on a further pivot lever 13 . The further pivot lever is formed and arranged as a mirror image of the first pivot lever 5 and is therefore likewise referred to as the “first pivot lever”. The first swivel lever 13 can also be moved via the first swivel axis 14 by means of the swivel drive 15 corresponding to the swivel drive 8, so that the third roller 12 can figure 1 shows the stop position with the Figure 4 Move between the working positions shown in . The angle by which the two first pivot levers are each pivoted to move the second or third roller between its parking position and its working position is approximately 45°.

[0040] The second roller 6 and the third roller 12 can be designed identically, so that after the wear limit of one of the two rollers has been reached, the worn roller can be replaced by a new roller without being out of service for a longer period of time. Alternatively, the second and...

Abstract

In a calender having a frame (1), in which a first roll (2), a second roll (6) and a third roll (12) are mounted, wherein, during operation of the calender, the first roll forms a nip (28) either with the second roll (6) or with the third roll (12), to which end the second and third rolls can be moved between an operating position and a parked position, at least one fourth roll (16) is provided which can be moved between an operating position, in which it forms a nip (28) with the first roll (2), and a parked position without changing the parked positions of the second and third rolls (6, 12).

Description

technical field [0001] The invention relates to a calender, in particular for a textile, nonwoven, plastic or paper product web, having a frame in which a first roller, a second Two rolls and a third roll, wherein the first roll can form a nip (Nip) with either the second roll or the third roll when the calender is running, for which the second roll can The third roller can move between the working position where the roll gap is formed and the first parking position, and the third roller can move between the working position where it forms a roll gap with the first roller and the second parking position. Such a calender is known from DE 100 05 306 C1. The first and second parking positions of the second and third rollers are so remote from the first roller that the respective other rollers can be moved from the working position into the parking position and vice versa. Background technique [0002] In calenders, especially those for processing textile, nonwoven, plastic or...
