  • Patent number: 6185787
    Abstract: In a plant for processing textile fibers, the fine cleaning is effected at a point at which the stream of fiber material already has been subdivided (e.g. for the subsequent carding process), e.g. in the card filling chute. The cleaning device comprises at least one separating element arranged above the transporting roll. The trash eliminating system includes a system for eliminating material separated from the zone of the roll.

  • Patent number: 6145166
    Abstract: In a fiber processing machine with a separating edge in which fibers as well as air are guided in a substantially predetermined transporting direction past the edge, trash particles are selectively removed from the fiber/air stream with the help of the edge. The adjustment of a separating element, in particular, the setting of the angular position of a separating surface and/or the penetration depth upstream from the separating surface is linked with an adaptation of the width of the eliminating gap. Also, at least one measure can be taken for eliminating, as far as possible, a pressure drop and/or air turbulences downstream (in the transporting direction) from the edge. Downstream from the edge, a flow pattern as laminar as possible is generated or maintained, respectively.

  • Patent number: 5224243
    Abstract: The cleaning or blow room line comprises at least one bale opening machine connected by ducts and at least one cleaning machine and a blender with a plurality of cards. The transport of the fiber flocks extracted by the at least one bale opening machine through the cleaning line is achieved by suction ventilators provided for such cleaning line. After at least one cleaning location a pressure sensor is arranged in an associated duct and delivers a signal to a control or regulator which controls or regulates, as the case may be, the size of a false air opening which co-dictates the air flow through the ducts. The false air opening can be constructed as an adjustable element in the form of a hinged flap or a slide element positioned relative to an opening in a duct, whereby the regulator controls the extent to which the flap or slide member is pivoted or slid, thereby adjusting the amount of air that is drawn into the duct.

  • Patent number: 5054166
    Abstract: A carding element (3) on the periphery of a carding or cleaning roller (1) is arranged to be movable in the direction toward or away from the roller (1) and is movable to selectively present different types or sizes of clothing elements (14.1, 14.2, 14.3 and 14.4) in proximity to the roller (1) so as to effect different actions on the fibers as the clothing elements on the carding element function as counter clothing elements for the clothing (12) of the carding or cleaning roller. This facilitates optimization of the cleaning function obtainable through the cooperation between the clothing (12) on the card drum and the clothing elements (14).

  • Patent number: 5048156
    Abstract: The invention relates to a method of treating cotton contaminated or imbued with honeydew. For this purpose, cotton flocks are fed into a microwave oven, in which the cotton flocks are heated by microwave energy, thus reducing the stickiness or tackiness of the honeydew such that there are no processing disadvantages on subsequent machinery. The microwave oven basically comprises a conveyor belt on which the cotton flocks are conveyed through a passage or channel provided with microwave generators. At the exit or outlet of the microwave oven the cotton flocks are transferred to an opening unit which transfers the cotton flocks into a feed chute or shaft.

  • Patent number: 5025533
    Abstract: Individual fiber components are blended in accordance with the properties of a required intermediate product such as a card sliver or an end product such as a yarn. The fiber bales are combined into component groups and the fiber components in the groups are accurately supplied by metering devices to a blender in which the components are uniformly mixed. The product from the blender may be cleaned and thereafter carded into a sliver. The characteristics of the sliver, such as the color, fiber, fineness and quantity, are tested and adjustments made in the blending in dependence upon any deviation from preset values for the characteristics.

  • Patent number: 5003670
    Abstract: The invention relates to an apparatus for reducing the stickiness or tackiness of cotton flocks. For this purpose, cotton flocks delivered by any suitable conveyor structure are received in a flock chute and brought, by rolls or rollers, as a fiber batt between a number of heated rolls or rollers, in order to be heated such that the stickiness or tackiness of the honeydew on the cotton is thus reduced to an extent which no longer has an adverse effect on subsequent machinery. Downstream of the heated rolls or rollers the fiber batt is again opened into cotton flocks by an opening roll or roller and fed to a pneumatic conveyor line through which the cotton flocks are fed to the subsequent machine.
