Embodiment Construction

[0033] exist figure 1 A front view (this means shown in the direction of the material web guided through the calender 100) of a calender 100 configured as a so-called double calender is shown in FIG. The rollers 10a, 10b thereon are used for processing non-woven webs, fabric webs, plastic webs or paper webs and comprise a corresponding tool 20 which is likewise formed as a roller, in particular a lower roller.

[0034] The calender 100 comprises in particular a frame 101 on which a lower roll support 104 for supporting and vertically adjusting the lower roll 20 is arranged and on which a first pivot lever is respectively rotatably mounted pair 110a and a second pair of pivoting rods 110b. especially by Figure 2a and 2b A side view of a partly cut-away calender 100 is shown in , in particular in the axial direction of the calender rolls 10a, 10b, 20 or in a direction perpendicular to the material web 103 being guided through the calender 100 It can be clearly seen that on ...

Abstract

The invention relates to a calender (100) for treating a nonwoven web, a textile web, a plastic web or a paper web, the device comprises a frame (101) and at least two rollers (10a, 10b), the rollerscan each be selectively displaced into a working position (A1) in order to form a processing gap (102) with the corresponding tool (20) and alternatively into a parking position (P) and can each be rotationally driven by means of a respective drive unit (120a, 120b) which is mounted independently of the corresponding roller (10a, 10b). The drive units (120a, 120b) are mounted fixedly on the calender (100) or on at least one common guide (125, 125 ').

Description

technical field [0001] The invention relates to a calender, in particular a so-called double calender, for processing nonwoven, fabric, plastic or paper webs, comprising a frame and at least two rolls, The rollers are each selectively displaceable into a working position to form a processing gap with a corresponding tool and alternatively into a parking position and can each be rotated by means of their own drive unit independently of the respective roller bearing drive. [0002] For the processing of material webs, it is known in calenders that the material web to be processed is transported in the advancing direction and guided over rollers (also called processing rollers) and countertools (such as counterrollers) which are situated in the working position formed processing gap. The treatment roller is usually arranged here as an upper roller and the counter roller as a lower roller, wherein usually only the upper roller, or both the upper roller and the lower roller, are ...
