Embodiment Construction

[0024] figure 1 The opening roller housing 1 of the sliver opening device, generally designated 20, of an open-end spinning machine (known and not further shown) is shown. An opening roller 2 is rotatably mounted in the opening roller housing 1, which rotates in the direction of the arrow 5 during spinning operation and has a so-called opening roller clothing 3 on its periphery for carding Feed the fiber bar 4. Furthermore, a fiber sliver feed roller 7 rotatable in the direction of the arrow 6 and an associated feed plate 8 are mounted in or on the opening roller housing 1 . Such as figure 1 As shown, the feed fiber sliver 4 that is usually stored in a spinning barrel not shown is guided via the fiber sliver compactor 9 in the direction of the arrow 15 into the clamping area 10, which is formed by the feeding plate 8 and the fiber sliver Feed to Lola 7 composition. Here, a spring element (not shown) presses the feed plate 8 in the direction of the sliver feed roller 7, whi...

Abstract

The invention relates to a feed plate of a fiber rod opening device of a free end spinning machine. The feed plate a concave clamp region and a concave support surface. The clamp region is for conveying feed fiber rods using fiber rod feed rollers. The support surface is for fixing fiber fringings formed with opening rollers when carding the feed fiber rods. According to the regulations of the invention, the feed plate (8) has a feed plate component (21) which is changeable and fixed on a feed plate support (24). The feed plate component has a slide for the feed fiber rods. The slide seamlessly extends from the clamp region (22) of the feed plate component (21) to a fiber fringing support surface (23). The feed plate component (21) is made through MIM technology and has smooth hard material layers at least in the clamp region (22) and the fiber fringing support surface (23).

Description

technical field [0001] The invention relates to a feed plate for a sliver opening device of an open-end spinning machine according to the preamble of claim 1 . Background technique [0002] Feed plates for sliver opening devices for open-end spinning machines have been known for a long time and are described in some detail in various embodiments in a large number of patent documents. [0003] DE3501842A1 for example discloses a kind of fibrous sliver opening device, and wherein, generally cylindrical, preferably grooved fibrous sliver feeds roller and supporting to the cotton plate and forms the nip area that feeds the fiber sliver usefulness, and wherein, to the cotton plate Part of a pivotably supported feed curtain. Slowly rotating fiber sliver feed rollers feed the feed fiber sliver (which is preferably temporarily stored in the spinning drum) at a constant delivery speed to the opening rollers arranged behind it. The feed sliver on its way to the opening rollers first...
