Problems solved by technology

[0005] However, both of the aforementioned solutions have the disadvantage that a stable positioning of the circular expander in its magnetic mounting can only be achieved by complex adjustment operations
Furthermore, the state of suspension provided in a complex manner and thus the resulting fabric gap is negatively influenced by external influences, for example by passing fabric, and is therefore unstable

Embodiment Construction

[0017] In FIG. 1 a circular expander unit 1 is shown which essentially comprises a vertically arranged circular expander 2 with a variable diameter which is passed through a telescopic central carrier 3 It is supported in the tubular fabric inlet 4 arranged below and in the tubular fabric outlet 5 arranged above. The tubular fabric 12 is supplied to the circular expander via a feed roll 6 arranged centrally below the circular expander unit 1 . The tubular fabric inlet 4 essentially consists of a centrally arranged rotationally symmetrical body 7 , which is rigidly connected to the lower end of the central carrier 3 , and an outer magnetic support 8 separated by a first fabric gap 14 .

[0018] The tubular fabric outlet 5 essentially consists of a roller bearing 9 known per se, consisting of pairs of support rollers and fixed rollers, between which the The circular expander forms a second fabric gap 14.2 through which the tubular fabric is guided. The tubular fabric 12 is spr...

Abstract

The aim of the invention is to provide a circular expander that allows an easy-to-adjust, continuous passage of textiles while not impairing the quality of the passing tubular fabric. For this purpose, a magnetic bearing is provided optionally at the inlet or outlet of the circular expander and a conventional roller bearing is provided at the opposite end of the circular expander.

Description

technical field [0001] The invention relates to a circular expander for processing woven tubular fabrics, which circular expander is integrated in a processing unit and is held suspended in a vertical configuration. [0002] The circular expander comprises: a telescopically movable central carrier on which is hinged an outwardly expandable support, wherein the support is connected to means for longitudinally guiding said tubular fabric a first device configured as a tubular fabric inlet at one end of the central carrier for feeding the tubular fabric; a second device configured as a tubular fabric outlet at the other end of the central carrier for Lifting means for leading out said tubular fabric; optionally acting on said first or second means for adjusting the size of the circular spread; and means operatively connected to said central carrier for Locks the adjusted size of the circular expansion. Background technique [0003] Circular expanders of a similar construction...
