摘要:
In an apparatus for fiber-sorting or fiber-selection of a fiber bundle comprising textile fibers, especially for combing, the fiber bundle is supplied to a fiber-sorting device, clamping devices are provided, which clamp the fiber bundle at a distance from its free end, and mechanical device is present, which generates a combing action from the clamping site to the free end of the fiber bundle. To increase productivity in a simple manner and obtain an improved combed sliver downstream of the supply device there are at least two rotatably mounted rollers rotating rapidly without interruption, the combing device are associated with a said roller, and an arrangement for optimum feed and/or positioning of the fiber material to be combed is associated with the combing device.

In an apparatus for the fiber-sorting or fiber-selection of a fiber bundle which is supplied by means of a supply device to a fiber-sorting device, mechanical means are present which generate a combing action in order to loosen and remove non-clamped constituents from the fiber bundle, and a take-off device is present to remove the combed fiber material. To enable an improved combed sliver to be obtained, downstream of the supply device there are arranged at least two rotatably mounted rollers with clamping devices for the fiber bundles, which clamping devices are distributed around the periphery of the rollers, wherein in the region between the rollers, devices are present which provide an optimum feed of the fiber material and/or provide optimum positioning of the fiber material for transfer and take-up from the first roller to the second roller.

In an apparatus for the fiber-sorting or fiber-selection of a fiber bundle comprising textile fibers, especially for combing, fiber is supplied by a supply device to a fiber-sorting device, especially a combing device. Clamping devices clamp the fiber bundle at a distance from its free end, and a mechanical device combs the free end to loosen and remove non-clamped constituents, for example, short fibers, neps, dust and the like. To increase productivity and obtain an improved combed sliver, downstream of the supply device there are at least two rotatably mounted rollers rotating rapidly without interruption, which are provided with the clamping devices, and measured value sensors for detecting values relating to the fibers or machine settings are connected to a control and regulation device, which is arranged to effect actions in dependence on the measured values.

In an apparatus for the fibre-sorting or fibre-selection of a fibre bundle comprising textile fibres, especially for combing, which is supplied to a fibre-sorting device, especially a combing device, having clamping devices which clamp the fibre bundle at a distance from its free end, which is combed to remove non-clamped constituents, the clamping devices each comprise two clamping jaws. To increase productivity and to enable an improved combed sliver to be obtained, downstream of the supply device there are arranged at least two rotatably mounted rollers rotating rapidly without interruption, the clamping devices being spaced apart in the region of the periphery of the rollers, and each clamping device comprising at least one nipper part which is at least partially resilient. The clamping jaws may have a high coefficient of friction in the region of their clamping surfaces.

In an apparatus for the fiber-sorting or fiber-selection of a fiber bundle comprising textile fibers, especially for combing, which is supplied by a supply device to a fiber-sorting device, especially a combing device, having clamping devices, which clamp the fiber bundle at a distance from its free end, for combing to remove non-clamped constituents, at least one take-off device with a sliver-forming element is present, downstream of which is a drafting system. To increase productivity and improve the combed sliver, the fiber-sorting device has at least two rotatably mounted rollers rotating rapidly without interruption, having the clamping devices and between the sliver-forming element and the drafting system the at least one fiber sliver is present in the form of a fiber structure having a width greater than its height, for example, following spreading by a web-spreader.

An apparatus for splicing a leading end of a first sliver deposited in a coiler can and a trailing end of an out-running second sliver fed into a fiber processing machine, includes a device for tapering the leading and trailing ends to obtain gradually tapered length portions thereof; a device for positioning the tapered length portions side by side to obtain a juxtapositioned relationship thereof; a pressure-applying constriction through which the first and second slivers pass for splicing together the leading and trailing ends by pressure; and a device for introducing the first sliver, spliced to the second sliver, into the fiber processing machine.
摘要:
A method and apparatus for piecing lap sheets in a textile machine, such as a comber or ribbon lap machine. The machine is stopped when a lap roll EL is nearly emptied. A pressing member 53 at a rest position C1 is moved to an operating position C2, and a breaking comb 32 is moved from a rest position A1 to an operating position A2 so that the lap sheet LP2 is broken. A full lap FL is then rolled onto a pair of feed rollers 10 and 11. A suction pipe 43 is then moved to an operating position B1, so as to engage with an end S1 of a new lap sheet LP1 from the full lap roll FL. The suction pipe 43 is then moved to a position B3 located at a distance from a nip line N1 longer the length of the lap sheet LP1 from the nip line N1 to its edge, causing the ends of the old and new lap sheets to be superimposed. A reverse rotation of the feed rollers 10 and 11 then occurs, so that the fibers of the new lap sheet LP1 at the superimposed portion are stretched. Finally, a pressing member 53 is again moved to the operating position C2, so that the fibers at the superimposed portion are pressed toward the lap sheet plate 20 to obtain a neatly superimposed condition.
