Embodiment Construction

[0034] figure 1 The opening roller 1 according to the invention is shown in side view. A metal card clothing 3 is arranged on a support ring 2 on its radial outer circumference. The metal card clothing is a plurality of coils with a constant inclination arranged axially on the support ring 2 . The opening roller 1 rotates around an axis 4 at a high rotational speed in accordance with normal operating conditions. According to the radial direction of the opening roller 1, the fibers fed, for example, in the form of a fiber sliver are caught when they reach the dial element of the metal card clothing 3 and are released from the fiber sliver. Due to the high speeds, the dial elements are subject to high mechanical wear during continuous operation.

[0035] figure 2 A section of metal clothing 3 is shown in side view. The metallic card clothing 3 has a stitch area 5 for fastening to the support ring 2 . In particular, the shape of the stitches used should match the shape of ...

Abstract

The invention relates to a spinning machine, in particular to an opening device of a free end spinning machine. The opening device is provided with metallic card clothing (3) or ring clothing (11) used for individually separating the fibers of the fed-in fiber strips. The opening device of the invention is characterized in that the metallic card clothing (3) is pre-bent according to the geometricshape of a supporting ring (2), the ring clothing (11) is provided with the required geometric shape of a processed part, the surface of the corresponding processed part is provided with a structure with at least two layers, wherein an outer layer (13) is a hard material layer which is partially or wholly made of extremely hard material component, and arranged on a base layer (12).

Description

technical field [0001] The invention relates to a spinning machine, in particular to an opening device of an open-end spinning machine. The opening device is equipped with metal clothings or clothing rings for the individual separation of the fibers of the incoming fiber slivers. In addition, the present invention also relates to a manufacturing method of the opening device. Background technique [0002] During the production of yarns, in certain work steps it is required to separate the fibers to be processed from one another, that is to say to loosen the fiber assemblies from one another. In another manufacturing step, for example, it is required to arrange the fibers as parallel as possible to each other. This process is called parallelism. The fibers to be processed are in mechanical contact with the processing device, both during fiber opening and during fiber parallelism. After the mechanical contact, a mechanical wear occurs on the device which is detrimental on t...
