Embodiment Construction

[0025] figure 1 A card 1 according to the invention is shown in , which has a feed side (not shown) for fiber bundles and a discharge side 1 b for loose fibers 20 .

[0026] In the card 1, the fiber bundle is introduced at the infeed side of the device and is introduced into the cylinder 2 via rollers (not shown here) of the front drum, or directly into the cylinder 2, at which rollers in the first stage The fiber bundles are unraveled into individual fibers and aligned. During the transport of the fiber bundle on the cylinder 2 , the stripping rollers and work rolls 3 , 4 fix the fibers on the cylinder 2 so that the first bulk fibers 20 are formed. Loose fibers can be extracted from the cylinder 2 by transfer rollers 5 . In this case, the cylinder 2 rotates in a clockwise direction and its clothing or teeth are likewise inclined in a clockwise direction or in the direction of rotation. The transfer roller 5 rotates counterclockwise, wherein the clothing or teeth of the tra...

Abstract

The invention relates to a carding machine for producing fleece from fiber material, comprising at least one tambour (2), having at least two doffing rollers arranged one after the other in the working direction and having a compressing roller (8), which is operatively connected to all doffing rollers downstream of the tambour (2), wherein the carding machine (1) is designed to transfer at least two layers of card web (20) by means of at least two doffing rollers to a compressing roller (8), wherein each of the at least two layers of card web are compressed separately by means of the compressing roller (8) and are joined on the compressing roller (8) into a single layer of card web (20) and said layer of card web (20) is removed, by means of a transfer roller (9), on an outlet side of thecarding machine for further processing. The invention is characterized in that the compressing roller (8) has a diameter of at least 600 mm.

Description

technical field [0001] The invention relates to a card for producing fiber webs from fibrous material, said card comprising at least one cylinder and comprising two doffers and press rolls arranged next to each other in the working direction, said press rolls being connected to All doffers arranged downstream of the cylinder are in active connection, wherein the card is configured for delivering at least two layers of loose fibers by means of at least two doffers to press rollers, wherein each of the at least two layers of loose fibers is One layer is compressed separately and assembled on press rolls to form a single loose fiber layer and the loose fiber layer is drawn off for further processing on the discharge side of the card by means of transfer rolls. Background technique [0002] Conventional cards have cylinders from which loose fibers are removed at one or more locations. Each layer of loose fibers is individually compressed and then deposited on top of each other ...
