Problems solved by technology

This is time consuming and requires new sensors to be prepared each time, which is costly
Moreover, such sensors are required in each component to be monitored, which again raises the cost

[0046] figure 1 An arrangement with a carrier 30 and a card wire 10 is shown, which is constructed according to the first embodiment of the invention.

[0047] The bracket 30 includes an adhesive layer 33 on which a magnetic strip 34 is mounted. On the side of the card clothing 10 facing the carrier 30 there is a backing plate 90 which consists of a magnetizable material, such as steel. The card clothing 10 is mounted or held on the support 30 via said back plate 90 .

[0048] On the side facing away from the carrier 30 , the backplane 90 is attached to the electrically conductive layer 13 by means of the intermediate layer 14 , here designed as an adhesive layer. On the side of the electrically conductive layer 13 facing away from the support 30 , the base 12 of the clothing 10 is now fastened, which base can consist, for example, of a plurality of layers or of fabric layers glued together. Base 12 is typically constructed from five layers of cotton fabric. Since the base...

Abstract

A carding cloth (10) has a backing (12), carding needles (11) passing through this, held in position thereby and projecting on a first side of the backing (12) and an electrically conductive layer (13, 15) arranged on a second side on the backing (12) facing away from the first side such that it is in electrical contact with the needles (11) on the second side of the backing (12). Or the layer (15) is a component of the backing (12), and the needles (11) contact the layer (15) through said backing. The layer (15) can be a textile fabric (15) with electrically conductive threads which are coupled together electrically directly or indirectly via the carding cloth needles (11), which threads can extend longitudinally or transversely to the cloth (10), which has an electrically conductive contact element (20) such that it contacts the layer (13, 15) electrically in such a manner that the contact section is electrically coupled to all the threads. The contact element (20) has a connection section (16) designed to electrically contact an external element (50). A carding bar (10, 20, 30) comprises a cloth holder (30) having a holding section and an electrically conductive cloth connectionsection (20) forming the external element (50) and the cloth (10) held stationary in the cloth holder (30). A spinning preparation machine has a carding bar (10, 20, 30) of this type, a carding bar holder (70) to hold the carding bar (10, 20, 30) and a carding bar contact section (3) designed to be electrically coupled to the cloth connection section (20) when the carding bar (10, 20, 30) is mounted on the carding bar holder (70).

Description

technical field [0001] The invention relates to a card clothing, a clothing carrier provided therefor and a spinning preparation machine, such as a card, equipped with these. Background technique [0002] Such card clothings are known. The clothing mainly comprises a base through which the clothing needles, which are U-shaped in cross-section and groove-shaped, pass through the base. The free ends of the clothing needles protrude from the base from the respective side of the base and interact with a clothing provided eg on a cylinder. Due to the very small distance between the two clothings (for example 0.2 mm), the needles of these clothings come into mechanical contact with each other due to thermal deformations, eg due to operation or ambient temperature. This leads to excessive mechanical loading of the individual clothings and possible damage. [0003] To overcome said problems, different solutions have been developed in order to detect the mutual contact of two inte...
