Embodiment Construction

[0048] figure 1 An opening roller housing 1 for a sliver opening mechanism of an open-end spinning device is shown. An opening roller 2 is mounted rotatably around a rotation axis 22 in the opening roller housing 1 . The opening roller 2 has a so-called opening roller clothing 3 on its outer circumference for carding the feed fiber sliver 4 . The opening roller clothing 3 comprises teeth, the tips of which lie on a cylindrical surface 13 which delimits the opening roller 2 . The opening roller 2 rotates in the direction of arrow 5 during the spinning operation.

[0049] In or at the opening roller housing 1, a fiber strip feeding drum 7 rotatable in the direction of arrow 6 is also installed. It corresponds to the clamping face 10 of the feed plate 11 which is pivotably mounted by means of the feed plate seat 8 . Such as figure 1As shown, the feed fiber sliver 4 that is usually stored in a spinning can, not shown, is sent by the agglomeration device 9 in the direction of ...

Abstract

Fibre band opening device for an open-end spinning device and feed tray for the fibre band opening device are provided. The feed tray (11) has a clamping surface (10), which is designed to transport,in conjunction with a fibre band pull-in cylinder (7), a feed fibre band (4) towards an opening roller (2) having an opening roller clothing (3), the tips (12) of which lie on a circular cylindrical surface, a support surface (14) for fixing a fibre tuft, which is processed by the opening roller (2) by combining, the distance of which support surface from the circular cylindrical surface (13) is tapered in the fibre transport direction to a minimum distance, and a transition area (20) having a convex curvature between the clamping surface (10) and the support surface (14). The support surface(14) has a distance (18) of between 4 and 8 millimetres from the circular cylindrical surface (13) at the beginning of the support surface (14) with respect to the fibre transport direction, and the minimum distance (19) of the support surface (14) from the circular cylindrical surface (13) is less than 1.5 millimetres.

Description

technical field [0001] The invention relates to a sliver opening mechanism for an open-end spinning device, comprising a feed tray, a sliver feeding drum and an opening roller. The sliver feed drum is designed in conjunction with the nip surface of the feed plate to convey the feed sliver to the opening roller. The feed plate has a support surface for holding the fiber bundles which are opened by the opening rollers. The feed plate also has a transition region with a convex curvature between the clamping surface and the support surface. The invention also relates to a feed plate having a clamping surface, a support surface for fixing the fiber bundle and a convex transition region between the clamping surface and the support surface. Background technique [0002] Various embodiments of sliver opening mechanisms for open-end spinning devices are known and explicitly described in a large number of patent documents. [0003] DE 3501842 C2 describes, for example, a sliver ope...
