Embodiment Construction

[0056] figure 1 Shown is a card, for example a flat card TC from Trützschler, which has a feed roller 1, a feed plate 2, licker-in rollers 3a, 3b, 3c, cylinder 4, doffer 5, stripping Roller 6, nip rollers 7, 8, web guide 9, bar horn 10, delivery rollers 11, 12, rotary carding with card top bar rollers 13a, 13b and card flat 14 Top 13, can 15 and coiler 16. Reference sign M denotes the center point (axis) of the cylinder 4 . The reference numeral 4a designates the card clothing, and the reference numeral 4b designates the 4-rotation direction of the cylinder. Arrow A indicates the working direction. The direction of rotation of the roller is indicated by the curved arrow drawn inside the roller.

[0057] In the pre-carding zone (located between the licker-in roller 3c and the carding top guide roller 13a at the rear), opposite the cylinder 4, a plurality of stationary carding elements 23' according to the invention are arranged; Between the doffer 5 and the carding top cot...

Abstract

The card has a fixed carding element (23'-1) positioned opposite to a cylinder clothing (4a) and comprising end regions that are supported on the card. An elongate carrier element (24) made of aluminum or aluminum alloy extends between the end regions of the fixed carding element, where an inward face of the carrier element is located opposite to the cylinder clothing at a predefined spacing. A stressing element (40) i.e. screw clamp, made of steel or aluminum is associated with the carrier element for axial pre-stressing of the carrier element.

Description

technical field [0001] The invention relates to a device on a flat card or a roller card, wherein at least one working element and / or functional element, such as a stationary carding element or a rotating card top flat, is provided, at least one working element and / or the functional element has between the two end regions an elongated carrier for support on the card, said carrier having an inwardly oriented region (towards the working area of ​​the card), said inwardly oriented The area is opposite to the cylinder wire at a certain distance. Background technique [0002] In existing carding machines of construction mode, in addition to the carding top with elastic clothings, fixed carding elements with all-steel clothings are also used during the carding process, the actual clothings being arranged on high-precision carrier parts, These carrier parts are then mounted on the machine. Currently, extruded aluminum profile parts are often used as load-bearing parts. In addi...
