Abstract: A device is provided on a spinning preparation machine for receiving a sliver from a discharge device of the spinning preparation machine and transporting the sliver to a downstream machine, the spinning preparation machine having a depositing region. The device has a support for receiving the sliver deposited from the discharge device in the depositing region, and a moving device for moving the deposited sliver relative to the discharge device in the depositing region for forming a free standing sliver bundle, and for moving the free standing sliver bundle out of the depositing region for transport to a downstream machine.

Abstract: A can-free system for handling fiber sliver includes a sliver delivery device which deposits fiber sliver in the form of a free-standing sliver pile in a depositing area. A sliver receiving device is disposed in the depositing area to receive and collect the free-standing fiber sliver pile delivered by the delivery device. A packaging apparatus compresses the collected free-standing fiber sliver pile applies one or more straps to the compressed free-standing sliver pile.

Abstract: A carding machine has a number of rollers including a cylinder and having at least one clothed and/or unclothed machine element located opposite the cylinder at a spacing therefrom. The machine may have further elements influencing the carding nip. In order to make possible a carding nip between the cylinder and the clothed and/or unclothed counterpart element that remains constant or virtually constant when heat is generated, the parts influencing the carding nip are so construed that they have thermal expansion characteristics which are such that, when subjected to the heat acting on them in use, the carding nip remains substantially constant.

Abstract: In an apparatus for measuring the mass of fibre material passing through a spinning preparation machine or system or through a nonwoven production device, at least one microwave resonator is provided. In order to improve measurement of the mass of fibre material in a cleaning system, especially between a bale opener and carding machine, and to use that measurement for closed-loop and/or open-loop control, the fibre material is present in the form of fibre flocks and the fibre flocks pass through a measurement pathway having a measuring device having the at least one microwave resonator.

Abstract: A roller for a fibre-processing machine, for example a spinning preparation machine such as a flat card, cleaner or the like, flock feeder, roller card, nonwoven-forming machine or the like, comprises a roller body. In order to make possible, by simple means, economical manufacture and adequate dimensional stability, for example a substantially constant carding nip, the roller body has at least one metal cylinder and at least one circular cylindrical sheath of fibre-reinforced plastics material surrounding the cylinder.

Abstract: In the case of an apparatus for a sliver-forming textile machine, especially a draw frame, flat card or the like, a fiber structure (fiber web) coming from the delivery rollers of a drafting system passes through a web guide and a sliver funnel with take-off rollers, the web guide has an inner wall (deflection and/or guide face), and a frictional resistance offered by the inner wall acts on the fiber structure. In order to allow in a simple manner an improved web guidance and sliver quality, and to permit the web guide to be adapted to different technical parameters, such as fiber material properties, working speed, a parameter relating to contact between fiber structure and inner wall is alterable.

Abstract: In an apparatus on a spinning room machine, especially a spinning preparation machine for depositing fibre sliver, in which there is a delivery device for delivering fibre sliver and a substantially planar receiving support surface for receiving and collecting the fibre sliver in the form of a can-less fibre sliver package, the receiving support surface being substantially unenclosed, the receiving support surface and the delivery device are displaceable relative to one another, the receiving support surface being movable back and forth horizontally. In order to effect simple discharge the fibre sliver package, together with the receiving support surface, is dischargeable from the machine, the fibre sliver package is removable from the receiving support surface and the receiving support surface is displaceable back into the machine.

Abstract: In an apparatus in a spinning mill for transporting a can-less fibre sliver package between a sliver-delivering spinning machine, for example a draw frame, or a storage means and a further processing device or a further storage means, having a support for receiving the can-less fibre sliver package, the support being substantially unenclosed, the support and the can-less fibre sliver package are transportable in common. In order to effect simple transport of the can-less fibre sliver package, there is a transport device for common transport of the support and at least one stably positioned fibre sliver package, the transport device being track-guided or freely movable.

In order to effect simple transport of the can-less fibre sliver package, the support for receiving the at least one fibre sliver package can be brought to the sliver-delivering spinning machine or to the storage means and, after the package has been received, the support, together with the stably positioned fibre sliver package, can be supplied to the further processing device or to the further storage means.

A storage device, for example a belt storage means, is provided for receiving at least one fibre sliver package, in which the at least one fibre sliver package is stably positionable.

Abstract: An apparatus on a spinning machine for depositing fibre sliver. The apparatus comprises a delivery device comprising a coiler plate adapted to deliver fibre sliver in the form of a can-less fibre sliver package. The apparatus also comprises a substantially planar receiving support surface onto which the fibre sliver is deposited, the receiving support surface adapted to move back and forth in a deposition area with respect to the delivery device through a substantially horizontal stroke. The receiving support surface is also adapted to move away from the delivery device in a substantially vertical stroke during delivery of the fibre sliver. The delivery device and the receiving support surface are both adapted to remain in contact with the fibre sliver as it is deposited in the form of a can-less fibre sliver package, such that the fibre sliver package is stabilized during the substantially horizontal stroke and during lowering of the receiving support surface.

Abstract: An apparatus in a spinning room for providing at least one fiber sliver package to a sliver-fed machine having at least one feed position.

The transport arrangement is arranged to supply at least one fiber sliver package to a feed position and the fiber sliver package(s) can be stably positioned at the feed position.
