20100236025 | CARD FLAT BAR FOR A CARDING MACHINE, FOR COTTON, SYNTHETIC FIBRES OR THE LIKE, HAVING A CARD FLAT CLOTHING - In a card flat bar having a card flat clothing, the card flat clothing is magnetically attached to the card flat bar body and, in use, lies opposite a clothed roller. In order to hold the clothing element against the card flat bar in a structurally simple way in the event of an increase in force on the clothing, especially to prevent the card flat clothing from making contact with the cylinder clothing, and to allow quick replacement of the card flat clothing strip, on the fibre material inlet side of the card flat clothing—seen in the direction of rotation of the roller—there is associated with the card flat bar a counter-bearing, stop or the like with which a base of the clothing co-operates in the direction towards the cylinder. | 09-23-2010 |
20090293232 | APPARATUS ON A FLAT CARD OR ROLLER CARD HAVING A CYLINDER AND AT LEAST ONE DOFFER - In an apparatus on a carding machine having a cylinder and at least one doffer, in which the cylinder and the doffer each have an all-steel clothing having saw teeth, the clothing on the cylinder and the clothing on the doffer each have a point density per square inch (ppsi). For achieving increased production rate with the same quality or improved quality with the same production rate, the clothing on the doffer has a point density of at least 400 ppsi, and the ratio between the point density of the clothing of the cylinder and the point density of the clothing of the doffer influences the proportion of the fibre mass that is transferred from the cylinder to the doffer per revolution of the cylinder in the sense of a higher production rate or higher quality of the card. | 12-03-2009 |
20090158558 | SAW-TOOTH CLOTHING FOR ROLLERS AND/OR CYLINDERS OF FLAT CARDS OR ROLLER CARDS - A saw-tooth clothing for rollers and/or cylinders of flat cards or roller cards has a foot region and an adjoining tooth region (blade) in which teeth have been formed by cutting, with a tooth front a tooth back and two side flanks, wherein between the tooth back and the tooth front of two adjacent teeth there is a gullet and the teeth consist of at least two portions, with a first portion, forming a technologically effective region. In order to provide a clothing that retains a high level of aggressiveness over its lifetime, the first portion of the tooth front is convex or approximately convex in the direction of movement of the clothing. | 06-25-2009 |
20090024245 | Apparatus for monitoring and securing danger zones on power-driven textile machines - In an apparatus for monitoring and securing danger zones on power-driven textile machines, in particular spinning room preparatory machines, having movable machine parts, an optical monitoring device monitors a movable danger zone to form a movable protection zone, such that a person and/or an object intruding into the danger zone triggers a switching operation. To produce an apparatus that allows guarding of danger zones in a simple and reliable manner, stationary monitoring device is present, which is selectively activatable and forms a dynamically movable protection zone around the movable danger zone. | 01-22-2009 |
20090000076 | Apparatus for the fibre-sorting or fibre-selection of fibre bundle comprising textile fibres, especially for combing - In an apparatus for the fibre-sorting or fibre-selection of fibre material which is supplied by means of a supply device to a fibre-sorting device, and a mechanical device is present which generates a combing action to remove non-clamped constituents such as short fibres, a clamping element is present. Downstream of the supply device there are arranged at least two rotatably mounted rollers with clamping devices for the fibre bundles, and the device for generating a combing action is associated with a said roller, wherein for the suction of the supplied fibre bundles, at least one suction device is associated with the clamping devices in the region of the transfer of the fibre bundle from the supply device to the first roller and/or in the region of the transfer of the fibre material from the first roller to the second roller. | 01-01-2009 |
20090000075 | APPARATUS FOR THE FIBRE-SORTING OR FIBRE-SELECTION OF A FIBRE BUNDLE COMPRISING TEXTILE FIBRES, ESPECIALLY FOR COMBING - In an apparatus for the fibre-sorting or fibre-selection of a fibre bundle comprising textile fibres, especially for combing, which is supplied by a supply device to a fibre-sorting device, especially a combing device, having clamping devices, which clamp the fibre bundle at a distance from its free end, for combing to remove non-clamped constituents, at least one take-off device | 01-01-2009 |
20090000071 | APPARATUS FOR THE FIBRE-SORTING OR FIBRE-SELECTION OF A FIBRE BUNDLE COMPRISING TEXTILE FIBRES, ESPECIALLY FOR COMBING - In an apparatus for the fibre-sorting or fibre-selection of a fibre bundle which is supplied by means of a supply device to a fibre-sorting device, mechanical means are present which generate a combing action in order to loosen and remove non-clamped constituents from the fibre bundle, and a take-off device is present to remove the combed fibre 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 fibre 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 fibre material and/or provide optimum positioning of the fibre material for transfer and take-up from the first roller to the second roller. | 01-01-2009 |
20090000068 | APPARATUS FOR THE FIBRE-SORTING OR FIBRE-SELECTION OF A FIBRE BUNDLE COMPRISING TEXTILE FIBRES, ESPECIALLY FOR COMBING - In an apparatus for the fibre-sorting or fibre-selection of a fibre bundle comprising textile fibres, especially for combing, fibre is supplied by a supply device to a fibre-sorting device, especially a combing device. Clamping devices clamp the fibre 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 fibres, 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 fibres or machine settings are connected to a control and regulation device, which is arranged to effect actions in dependence on the measured values. | 01-01-2009 |
20080263831 | Device on a spinning preparation machine, for example a draw frame, carding machine, combing machine or the like, having a drafting system - In a device on a spinning preparation machine, having a drafting system for drawing at least one fibre sliver with drafting system rollers, forming drafting roller pairs, having power transmission means for driving the drafting system rollers and having a drive motor, the drive of the drafting system rollers is effected from different sides. In order to reduce the number of drive elements and to effect a substantial improvement in efficiency, the drive motor has two rotating drive elements, the drive of at least one roller pair being effected from one side by the first drive element and the drive of at least one other roller pair being effected from the other side by the second drive element. | 10-30-2008 |
20080244871 | Apparatus on a spinning room machine, especially a spinning preparation machine, for depositing fibre sliver - In an apparatus on a spinning room machine for depositing fibre sliver, a stationary delivery device for delivering fibre sliver and a substantially flat receiving support surface for receiving and collecting the fibre sliver as a can-less fibre sliver package are present. The receiving support surface, which is substantially unenclosed, is movable during the depositing process back and forth in the horizontal direction by a drive arrangement. In order to improve the production of the can-less fibre sliver package, the speed of the receiving support surface with the sliver package is alterable substantially on a reversal path such that a gradual braking to speed value zero to the speed of the back and forth movement are effected. | 10-09-2008 |
