Embodiment Construction

[0032] figure 1 A card according to the prior art is shown in which the fiber bundles are guided through channels to a feed roller 1 , a feed plate 2 , via a plurality of licker-in rollers 3 a , 3 b , 3 c to a cylinder 4 or a cylinder. On the drum 4 , the fibers of the fiber bundle are parallelized and cleaned by means of circumferential carding elements 20 which are fixed and arranged on the revolving flat 17 . The resulting fibrous web is then conveyed via a doffer 5, a stripping roller 6 and a plurality of squeeze rollers 7, 8 to a web guiding element 9, which transforms the fibrous web into a sliver by means of a collective bell mouth 10, so that The fiber sliver is transferred to subsequent processing equipment or cans 15 via detaching rollers 11 , 12 .

[0033] figure 2 A cross-section of the surrounding carding element 20 or flat strip is shown, wherein for reasons of simplification the clothings arranged on the base region 20 c of the flat strip 20 are not shown. acc...

Abstract

The present invention relates to a carding element (20) with a supporting body (20b), it being possible to fasten a fitting to the foot region (20a) of said supporting body, wherein a head region (20e) is arranged in a manner distanced from the foot region (20c) by at least one back part (20a). The invention is characterised in that the head region (20e) has at least one channel (20f) which extends at least partially over the length of the carding element (20), wherein in the channel (20f) a pressure on the head region (20e) of the carding element (20) can be generated. The invention further relates to a card or carding machine.

Description

technical field [0001] The invention relates to a carding element for a cotton card or a carding machine according to the preamble of claim 1 . The invention also relates to a card or carding machine. Background technique [0002] On cards of the current design, flats with flexible clothings (revolving flats) and / or stationary carding elements with all-steel clothings are used as carding elements for the carding process. Here, the actual clothing is accommodated by a high-precision support member. Currently, aluminum extruded profiles are usually used as support members. In addition to the numerous advantages such as low weight and high rigidity, the aluminum extruded profile also has the disadvantage that, in the case of single-sided heating which may occur during the carding process, it deforms towards the heated side. The higher the member, the greater the temperature difference that affects bending. Said deformations lead to a non-constant carding gap, which again le...
