Problems solved by technology

A disadvantage of the known construction is that the clamping element produces undesired bending stresses in the protruding journal
Expensive subsequent processing is therefore unavoidable
In addition, continuous shafts lead to higher roller weights

Embodiment Construction

[0010] Fig. 1 represents a carding machine, for example Truetzschler-DK 903 high-efficiency carding machine, it has feed roller 1, curtain type feed table 2, licker-in roller 3a, 3b, 3c, carding cylinder 4, doffer cylinder 5, stripping roller 6 , crushing and cleaning rollers 7, 8, non-woven guide elements 9, condensate guides 10, traction rollers 11, 12, revolving flats 13 with flat rods 14 covering the card clothing, cans 15 and rings Bar device 16. The direction of rotation of the rollers is indicated by curved arrows. Use A to indicate the working direction.

[0011] The drum 4 shown in FIG. 2 has a casing 17 made of sheet steel. The housing 17 is supported at its two ends on a substantially hollow cylindrical sleeve 20 or 21 (sleeve) across the drum bottoms 18 and 19 (disk) respectively. The sleeves 20, 21 are mounted on the drum bottom surfaces 18 and 19 by welding (22, 23). The sleeve 20 is fastened rotationally fixedly on a short cylindrical journal 24 by gluing, a...

Abstract

The invention relates to a roller for spinning preparing machine, such as carding roller of carding machine, doffer roller, etc. The roller has an outer shell, each end thereof supports on a hub fixed on a driving shaft. In order to produce a roller with smaller concentricity error (allowable error) and weight reduced apparently by a simple method, a separate shaft journal (puncheon) is connected to each hub and the shaft journals are glued to the hubs.

Description

technical field [0001] The invention relates to a roller for a spinning preparation machine, such as a card cylinder, a doffer cylinder, etc. for a carding machine, the housing of which is supported at its ends on a sleeve fixed to a drive shaft. Background technique [0002] A known cylinder for carding machines (DE-OS3531850) is provided with a continuous shaft which transmits torque by means of clamping elements. The drum is supported by flanges (sleeves) fixed on an outer steel disc and connected rotationally fixedly to the drive shaft by means of clamping elements. The clamping element can be a spring coil, for example. After the shaft is fixed, the machining (turning) of the journal and the housing surface is carried out in one operation to produce excellent concentricity. A disadvantage of the known construction is that the clamping element generates undesired bending stresses in the protruding journal. Expensive subsequent processing is therefore unavoidably neces...
