Embodiment Construction

[0025] figure 1 A card according to the prior art is shown in which loose fibers are guided via slides to feed roller 1 , feed table 2 , via a plurality of licker-in rollers 3 a , 3 b , 3 c to drum 4 or cylinder. The fibers of the loose fibers are parallelized and cleaned on the cylinder 4 by means of the stationary carding elements 13 and the endless flat strips 20 arranged on the revolving flat 17 . The resulting fiber fluff is then conveyed via a doffer 5, a take-off roller 6 and a plurality of pressure rollers 7, 8 to a web guiding element 9, which reforms the fiber fluff by means of a bell mouth 10 into a fiber sliver, The fiber strand is passed via take-off rollers 11 , 12 to a downstream processing machine or can 15 .

[0026] figure 2A cross section is shown through the flat strip 20 which is arranged on the revolving flat 17 and runs around. The cover strip 20 can be made of extruded aluminum and comprises a cover back 20a, a carrier 20b and a cover bottom 20c. A...

Abstract

The invention relates to a carding machine with a device for adjusting the carding gap during continuous operation, wherein the carding gap can be adjusted in sections on curved rails (14) at least on a part of the drum circumference, and / or can be The carding gap is adjusted on at least one flat strip (20) across the working width. According to the invention, at least one flat strip is designed to transmit current operating data to a control device ( 27 ) of the carding machine, wherein the position of the flat strip ( 20 ) on the cylinder ( 4 ) can be determined. Furthermore, the invention relates to a covering strip.

Description

technical field [0001] The invention relates to a carding machine with a device for adjusting the carding gap during continuous operation, wherein the carding gap can be adjusted in sections on curved tracks at least on a part of the drum circumference, and / or the carding gap can be adjusted during operation The width is adjusted on at least one cover strip. Furthermore, the invention relates to a covering strip. Background technique [0002] When cleaning or carding fibrous materials, such as cotton or man-made fibres, stationary or endless cleaning or carding elements are usually arranged opposite rotating rolls equipped with card clothings. In order to achieve a good cleaning or carding effect, the elements must be arranged as close as possible to the clothing of the rotating roller. Conditioning is performed cold and with the rolls at rest. The effective distance between the tips of the clothing and the carding elements lying opposite the clothing is referred to as th...
