    摘要： Fiber slivers must be condensed during the course of a spinning process or their mass must be determined. For this purpose there are employed so-called grooved pairs of rollers, that is to say, profiled rolls which define a sliver throughput groove which is limited or confined at both sides. The sliver is guided through a feed or delivery funnel up to the throughput groove. The danger thus exists that individual fibers can jam between the side surfaces or faces of the rollers which form the lateral boundaries of the groove. This danger is eliminated with the invention in that the fiber outlet opening of the feed funnel is located within the region of a wedge-shaped gap which is bounded by an overlapping zone of the side surfaces or faces of the rollers.

    摘要翻译： 纤维条必须在纺丝过程中冷凝或者必须确定其质量。 为此目的，采用了所谓的成对的一对辊，也就是说，形成限定或限制在两侧的纱条通过槽的成型辊。 条子被引导通过进料或输送漏斗直到通过槽。 因此存在各种纤维可能阻塞在形成槽的横向边界的辊的侧表面或面之间的危险。 本发明消除了这种危险，因为进料漏斗的纤维出口开口位于由辊的侧表面或面的重叠区限定的楔形间隙的区域内。

    摘要： In a flyer frame, winding of rovings is performed by utilizing the difference in rotation rate between a flyer and a bobbin. Therefore, it is necessary to reduce the rotation rate differences with increase of the bobbin diameter. The bobbin is driven through one of a pair of cone drums around which a belt is stretched, and the rotation rate of the bobbin can be adjusted by changing the belt position along the length of the cone. A device for compensating changes in roving winding tension comprises a link mechanism having at least two elements and disposed to connect a belt shift for moving a belt with a moving member capable of intermittent movement at a constant pitch. The link mechanism is moved by the moving member along a fixed guide member having a cam surface while part thereof is engaging the cam surface of the fixed guide member. By the cooperative action of the cam surface and link mechanism, the constant-pitch intermittent movement of the moving member is converted to a desired movement of the belt, thus compensating the changes of the roving tension.
