Problems solved by technology

This partly caused the area around the gear train to be soiled
Noise levels generated by gear transmissions are detrimental to efforts to create low-noise equipment
Also, during operation, the gears are pressed apart by the cotton passing between the calender rolls, as a result, slippage occurs between the teeth, which can also lead to gear wear

Embodiment Construction

[0025] figure 1 A set of calender rolls 1 is shown which consists of four calender rolls W1-W4 arranged one behind the other. The calender rolls are arranged slightly staggered back and forth, and between the calender rolls the cotton WT is conveyed meanderingly to a subsequent roll-forming device 2 . Furthermore, the cotton WT passes through a slope 3 between the two deflection rollers U1 and U2, below which there is a belt loop RS of a belt 5 which is guided by the other deflection rollers U3, U4, U5 and U6. A small roll W is formed within the belt loop RS, in which the cotton WT is wound on a sleeve H. The sleeve H is supported rotatably about the axis 7 by means of transverse supports (not shown in detail). The belt 5 of the roll forming device 2 is tensioned by means of deflection rollers U6 which are arranged to be rotatable in relation to the axis of rotation 9 by means of a double arm lever 8 . The double arm rod 8 receives the force of a cylinder 10 mounted in the ...

Abstract

An assembly compresses and feeds a fleece web to a processing station (2) via three or more calender drums (W1-4) coupled to a drive system (M1, Z6, R). Each drum axle (A1-4) esp. has a pulley wheel (Z1-Z4) with a belt (R) linked to a second pulley wheel (Z6) with drive (M1) motor. The belt (R) follows a snake-like route around the pulley wheels (R1-4) and is adjusted by a tension-setting device (30, 31, 33, RS). The tension setting device is coupled to a tension-correction unit (ST).

Description

technical field [0001] The present invention relates to a device for compacting a sliver and feeding it to a subsequent processing device having at least three calender rolls arranged approximately one behind the other and connected to a gear at least in their working position. Background technique [0002] Such calender rolls are used, for example, in sliver coils for the production of finishing laps. Here, a sliver is guided meandering between successively arranged calender rolls, and the sliver is then wound into small rolls by means of a sliver roll. As the sliver passes between the calender rolls, the calender rolls close, so that the fibrous material guided between the calender rolls is compacted or a compression of the passing cotton occurs. Calendering of the sliver serves to increase the strength of the cotton so that the lap can be unwound again without any problems in a subsequent process, eg in a comber. However, the use of such calender rolls is not limited to...
