Feed device for open-end spinning assembly

Feeding apparatus for a spinning assembly comprising:

• a transport arrangement for delivering sliver to an opener device and which forms a nip for the sliver presented to the opener device,
• a housing surrounding said transport arrangement,
• and a sliver funnel disposed upstream of said transport arrangement, said sliver funnel having an outlet opening which leads to the transport arrangement,
• wherein the sliver funnel is pivotally mounted on a shaft that is disposed crosswise with reference to the direction of travel of sliver through said sliver funnel so as to be swingably movable about said shaft between an operating position with said outlet opening in the vicinity of the transport arrangement and a servicing position with said outlet opening exposed to the outside of said housing for accommodating visual inspection of the position of the sliver inserted in the sliver funnel without requiring opening of said housing, whereby sliver can be laid correctly in said sliver funnel without requiring opening of said housing for the transport arrangement.

• a housing surrounding said transport arrangement,
• a sliver funnel disposed upstream of said transport arrangement, said sliver funnel having an outlet opening which leads to the transport arrangement, and
• a stationary sliver feed tube disposed upstream of the sliver funnel, wherein said sliver funnel is movable from its operating position into a servicing position where it lies as an extension of the stationary feed tube with said outlet opening exposed for accommodating visual inspection of the sliver inserted in the sliver funnel, whereby sliver can be laid correctly in said sliver funnel without requiring opening of said housing for the transport arrangement.

• a housing surrounding said transport arrangement,
• and a sliver funnel disposed upstream of said transport arrangement, said sliver funnel having an outlet opening which leads to the transport arrangement,
• wherein the housing has an opening through which the sliver funnel is accessible from the outside,
• wherein the sliver funnel is movable out of the housing through the opening into a predetermined servicing position and particularly for accommodating the threading of the sliver, and
• wherein the opening of the housing is at a side of the sliver funnel which can be moved out of the housing, crosswise with reference to the sliver funnel's guide passage to a position where said outlet opening is exposed for accommodating visual inspection of the position of the sliver inserted in the sliver funnel, whereby sliver can be laid correctly in said sliver funnel without requiring opening of said housing for the transport arrangement.

• a housing surrounding said transport arrangement,
• and a sliver funnel disposed upstream of said transport arrangement, said sliver funnel having an outlet opening which leads to the transport arrangement,
• wherein the transport arrangement includes a feed table and a feed roll, and
• wherein the sliver funnel and the feed table and feed roll constitute a structural unit that is movable out of the housing by way of a slide rod which holds them, said structural unit being movable between an operating position and a servicing position with said outlet opening exposed to the outside of said housing for accommodating visual inspection of the position of the sliver inserted in the sliver funnel, whereby sliver can be laid correctly in said sliver funnel without requiring opening of said housing for the transport arrangement.

• a housing surrounding said transport arrangement,
• and a sliver funnel disposed upstream of said transport arrangement, said sliver funnel having an outlet opening which leads to the transport arrangement,
• wherein said transport arrangement includes a feed roll and a feed table that is urged by spring elements against the feed roll, on which feed table the sliver funnel is applied in its operating position,
• wherein the sliver funnel bears on the feed table in such a way that the latter can be moved away from the feed roll by supplementary loading of the sliver funnel, and
• wherein the sliver funnel is movable crosswise with reference to the direction of travel of the sliver, said sliver funnel presenting an elongated guide rib that is applied to the feed table even in the servicing position of the sliver funnel.
