Embodiment Construction

[0087] figure 1 A cross-sectional view of a double-apron drafting mechanism 1 of, for example, a ring spinning machine is shown. The drafting mechanism includes a pair of feeding rollers 2a, 2b, a pair of middle rollers 3a, 3b and a pair of output rollers 4a, 4b. An apron guide is formed around the middle roller pair 3a, 3b. The bottom apron 9 is guided via the bottom roller 3b, the apron tensioner 11 and the deflection bridge 10 . The top apron 8 is guided around the top roller 3 a and the deflection device 5 . The bottom apron 9 is driven by the bottom roller 3b. The top apron 8 and the top roller 3a are driven directly or indirectly via the bottom roller 3b.

[0088] The roving 6 is fed via the feed funnel 7 to the pair of feed rollers 2a, 2b and from there is guided between the pair of intermediate rollers 3a, 3b to the pair of output rollers 4a, 4b via apron guides, from where the but The untwisted fiber sliver 12 is fed directly or via a compression device to the sp...

Abstract

The invention relates to a textile machine with at least one drafting unit (1) forming a main drafting zone and comprising a first pair of drafting rollers (3a, 3b) and a second drafting Roller pairs (4a, 4b), said drafting roller pairs each having an upper roller and a lower roller, wherein the first roller pair (3a, 3b) is assigned an apron guide with The upper apron (8) guided by the upper roller (3a) and the lower apron (9) guided around the lower roller (3b) are used to guide the fiber strands (6) to be drafted, at least one of the aprons (9) A multi-part deflection device (10, 30) is assigned, via which the apron (9) is deflected from a fiber guiding direction into a return direction, and the deflection device (10, 30) comprises A base body (32) and a deflection guide mechanism (31) arranged on the base body (32). The invention is characterized by a special design of the deflection device.

Description

technical field [0001] The invention relates to a textile machine with a drafting mechanism comprising two pairs of main drafting rollers forming a main drafting zone and each having an upper roller and a lower roller, The first pair of main drafting rollers in the direction of fiber flow is assigned an apron guide with an upper apron guided around the upper roller and a lower apron guided around the lower roller for guiding the drafted fiber strands, and at least one of the aprons is assigned a multi-part deflection device, through which the apron is deflected from a fiber guiding direction to a return direction, and the deflection device comprises A base body and a deflection guide mechanism arranged on the base body. [0002] Furthermore, another invention disclosed here but not claimed within the scope of the present application relates to a textile machine with a drafting mechanism comprising two drafting zones, each having a Main drafting roller pairs of upper and lowe...
