Abstract (en)
[origin: CN112111814A] 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.
