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.

Sliver discharge device

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.

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.

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.

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.

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.

A fiber processing method includes the steps of removing fiber tufts from a series of fiber bales; pneumatically conveying the fiber tufts in a duct; forming images of the conveyed material as it passes through a first location of the duct; determining the degree of lightness or the color of the fiber tufts by an image processing device; determining the degree of lightness of foreign substances, conveyed with the fiber tufts, by the image processing device; comparing the measuring values obtained by the image processing device with a settable limit value; and initiating a switching operation when the limit value is exceeded for branching off to a waste receiver the fiber tufts from the duct at a second location thereof.

A method of measuring fiber while being processed by a fiber processing machine, includes the following steps: measuring the length of fiber at an inlet of the fiber processing machine; measuring the length of fiber at an outlet of the fiber processing machine; and forming a difference between the values measured at the inlet and the values measured at the outlet for determining an extent of shortening to which the fiber is subjected as the fiber passes through the fiber processing machine.

A method of processing fiber includes the following steps: removing fiber tufts from a series of fiber bales by a tuft removing device of a bale opener traveling along the bale series; pneumatically conveying the removed fiber tufts in a duct in a direction of conveyance; detecting foreign substances by forming images of the conveyed material by an optical sensor device as the material passes through a location of the duct downstream of the bale opener as viewed in the direction of conveyance; determining the location of each fiber bale in the bale series; determining the degree of lightness, the degree of contamination or the color of the fiber tufts by an image processing device analyzing the generated images; and associating the degree of lightness, the degree of contamination or the color of the fiber tufts with the fiber bale from which the material passing through the duct location originates.
