Embodiment Construction

[0028] figure 1 A schematic side view of the card 1 is shown. The fibers are conveyed in the card 1 from left to right. The fiber mat 2 is first conveyed on the feed plate 3 and then enters the feed device 4 . The feed device 4 has a feed trough 5 which cooperates with a feed roller 6 . The fiber mat 2 gripped between the feed trough 5 and the feed roller 6 is then fed to the feed roller 7 .

[0029] From the feed roller 7 the nonwoven fiber proceeds to the cylinder 8 and is further processed between the cylinder 8 and a cover plate 9 which is here shown very schematically. The nonwoven fibers are then removed from the stripping roller 10 and conveyed to a compacting unit 11 where they are compacted into a sliver 12 .

[0030] figure 2 A schematic side view of a feed device 4 according to the invention is shown. The feeding device 4 can be such as figure 1 Shown is part of a card 1 , but it could also be part of a card or cleaner. The feed device 4 has a feed trough 5...

Abstract

The present invention relates to a feed trough (5) for a feeding device (4) for feeding flock fibres into a spinner preparation machine, having a main body (13) and at least one elastic lip (15) whichextends across a working width of the feed trough (5). According to the invention, a supporting strip (16) which extends across the working width is provided on the main body (13), the supporting strip (16) being spaced from the elastic lip (15), and the spacing being such that it can be closed by elastic deformation of the elastic lip (15). The invention also relates to a feeding device (4) forfeeding flock fibres into a spinner preparation machine, having a feed roll (6) and a feed trough (5) according to the description above.

Description

technical field [0001] The invention relates to a feed trough for feeding fiber bundles into a feeding device in a spinning preparation machine, said feed trough comprising a base body and at least one elastic lip extending along the working width of said feed trough, And the invention relates to a feeding device for feeding a fiber bundle into a spinning preparation machine, comprising a feeding roller and a feeding chute. Background technique [0002] A feed trough for a feed device is known from EP 0 926 274 A2. The feed trough has a gap forming elastically deformable element which is fastened to the support element. Preferably, at least relatively large foreign bodies cannot penetrate into the elastic region. Such foreign matter has been caught upstream from the elastic edge region between the gap forming element and the feed roller. The feed trough then rotates as a whole about the axis against the bias of the spring. This fact is detected by sensors in which foreig...
