Card clothings, flat strips with clothing and machines with flat strips

Abstract

The card wire (10) has a base (12), a card wire passing through the base, held in place by the base and protruding on a first side of the base (12) The needle (11) and the electrically conductive layer (13, 15) are arranged on the second side of the base (12) facing away from the first side, so that the layer is in contact with the clothing needle (11) in the Electrical contacts are made on the second side of the base (12). Alternatively the layer (15) is an integral part of the base (12) and the needles (11) pass through the layer in contact with the layer (15). The layer (15) has a textile fabric (15) with electrically conductive threads which are electrically coupled to each other directly or indirectly via the clothing needles (11), which extend along or transversely to the clothing (10), said The card clothing has electrically conductive contact elements (20), so that they are in electrical contact with the layers (13, 15), so that the contact sections are electrically coupled to all wires. The contact element (20) has a connection section (16), which is designed for electrical contact with an external element (50). The flat strips (10, 20, 30) have a clothing carrier (30) comprising a holding section and an electrically conductive clothing-connecting section (20) forming the outer element (50) and in said clothing carrier ( 30) Card clothing (10) held in a fixed position. The spinning preparation machine has such a flat strip (10, 20, 30), a flat strip support (70) for holding the flat strip (10, 20, 30) and a flat strip-contact section (3) , which is designed to be electrically coupled to the clothing-connecting section (20) when the flat strips (10, 20, 30) are mounted on the flat strip 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...

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
