Problems solved by technology

This creates the risk when the machine is restarted that a localized point of extreme weakness occurs on the fiber strip, so that the fiber must be removed for further processing in the next process, i.e. in the next plant aisle or corridor. belt, and cause the machine to stop running

Embodiment Construction

[0030] figure 1 The drawing device 1 is shown diagrammatically, on which there is a stretched fiber belt 2, followed by a pair of calender rollers 3 and a rotating disc 4 placed next to a pot-like device 5. The pair of drive rollers 6 leads the fiber strip 2 to the drawing device 1 . A deflection position 7 is installed between the drive roller pair 6 and the traction device. At the deflection point 7, the fiber strip 2 is deflected wave-like toward the lower deflection points 8.1 and 8.2 and the upper deflection points 9.1 and 9.2. The fiber band 2 is clamped by the drive roller pair 6 and the input roller pair 10 of the traction device 1 respectively. Between the pair of input rollers 10 and the pair of intermediate rollers 11 and between the pair of intermediate rollers 11 and the pair of output rollers 12, the fiber ribbon 2 is stretched in a predetermined form. Between the pair of intermediate rollers 11 and the pair of output rollers 12 is installed a pressure bar 13 ...

Abstract

In a method for opening a drafting arrangement (1) with a plurality of pairs of rollers for drawing a sliver (2), the fiber tape (2) between a pair of transport rollers (6) and an at least one input and a pair of output rollers (10, 12), a preferably input, at least one central and a pair of output rollers (10, 11, 12) comprising a drafting unit (1) taut, wherein each roller pair of the drafting unit (1) has at least one upper and one lower roll. Before opening of at least the input and / or middle roller pair (10, 11) of the drafting arrangement (1), the tension of the sliver (2) between the transport roller pair (6) and the drafting unit (1) is reduced, in particular released. In a corresponding drafting arrangement by means of a mechanical or electrical coupling or ; Control prior to the opening of at least the input and / or middle roller pair (10, 11) of the drafting arrangement (1), the tension of the sliver (2) between the transport roller pair (6) and the drafting unit (1) is reduced, in particular released.

Description

technical field [0001] The invention relates to a method of opening a traction device, belonging to the field of machinery, with a plurality of roller pairs for stretching fiber strips. The fiber belt between the driving roller pair and at least one input and output roller pair on the drawing device is to be tensioned, on the drawing device indicated by an input roller pair and at least one intermediate roller pair and output roller pair The fibrous bands, in particular, must be taut. Each roller pair of the pulling device indicates at least one upper roller and one lower roller, as does the pulling device with a plurality of roller pairs that draw the fiber band. Background technique [0002] From DE 10057699 A1 it is known to install a device on the drawing device to handle the fiber strip. On the equipment, the fiber belt between the feeding table and the input roller of the traction device is guided through the floating roller device and the fiber belt with the conveyi...
