A method for enabling the cleaning of fibers in a fiber cleaning machine in which a cleaning stream moves tufts around a rotating cleaning cylinder, the tufts being cleaned and opened. The cleaning action can be adapted to fibers of varying origin and to an increasing degree of opening in the course of cleaning. The cleaning stream is, to a large extent, controlled and controllable by decoupling it from the dynamic behavior of the transport streams which transport material to and away from the cleaning process. Compensation for variations in the cleaning stream, and in the material supplied for cleaning, are achieved by control of the cleaning intensity, in order that the tufts emerging from the cleaning process are constant and optimally cleaned and opened. The invention concerns also suitable fiber cleaning apparatus for the realization of the described method. The apparatus includes a cleaning cylinder positioned in a casing and a plurality of cleaning elements extending from the cylinder. The length, shape and density of the elements can change along the length of the cleaning cylinder so that the cleaning intensity varies along the length of the cylinder. Adjustable grid bars can be positioned below the cleaning cylinder.

Adjustable cleaning of fibers in a spiralled air path and apparatus

A method and apparatus for cleaning textile fibers for use in conjunction with an opening roller to which the textile fibers are fed and around which the textile fibers are conveyed, in the form of a fiber bat, in a transport direction. The apparatus includes an arrangement for conveying the textile fibers from an inlet to a clamping point proximate the opening roller; compressing and clamping the textile fibers, in the form of a fiber bat, with a clamping force, the clamping force having a magnitude which is a function of a characteristic of the fiber bat; drawing the fiber bat from the clamping point to a takeover point on a periphery of the opening roller, the fiber bat then being subjected to centrifugal force due to rotation of the opening roller; conveying the fiber bat, under the influence of the centrifugal force, to a separating blade; and separating an area of the fiber bat having contaminants concentrated therein resulting from the centrifugal force and from the drawing of the fiber bat.

Method and apparatus for the fine cleaning of textile fibers

A discharge device for discharging the waste from a fiber cleaning machine having a collecting basin and a blowing or sucking device. The discharge device has a collecting basin which is funnel shaped with a motor driven paddle wheel in the tapered part. The waste removal is controlled on the basis of weight indicating and/or filling level indicating sensors which are assigned to the collecting basin.

Device for the disposal of waste in a fiber cleaning machine

An apparatus and method for use in a cleaning process of textile fibers, and for use in conjunction with an opening roller. The apparatus includes a plurality of separating blades and guide elements which are spaced from the opening roller during the cleaning process. An assembly is provided for adjustably positioning a plurality of the separating blades and the guide elements during the cleaning process. The adjustment of the spacing of the separating blades and the guide elements from the opening roller can be accomplished remotely, either manually or by a motorized drive. A lever unit enables appropriate connection for effecting the various adjustments of the separating blades and the guide elements. The guide elements and the separating blades can be controlled and adjusted to suit the fibers to be processed.

Device and method for the fine cleaning of textile fibers having

A method for the discharge of the waste from a fiber cleaning machine with the retention of the operating pressure difference to the surroundings of the machine. The waste inside the machine is collected to a predetermined filling level and after this filling level has beeen reached only a predetermined part of the waste is removed so that the part of the waste which is not removed can be effective as a sluice layer. A discharge device for discharging the waste from a fiber cleaning machine having a collecting basin and a blowing or sucking device. The discharge device has a collecting basin which is funnel shaped with a motor driven paddle wheel in the tapered part. The waste removal is controlled on the basis of weight indicating and/or filling level indicating sensors which are assigned to the collecting basin.

Method and device for the disposal of waste in a fiber cleaning machine

A machine for cleaning textile fibres including a casing, a horizontal opening roller rotatably mounded in the casing, the roller body having a roller body and beater rods protruding from the peripheral area of the roller body and bar grates arranged below the underside of the opening roller. Textile fibres in the form of flocks are conveyed in a delivery air stream through an inlet which is arranged at a first end of the opening roller. An outlet for egress of the delivery air stream is arranged at the other end of the opening roller. In one arrangement, the radial length of the beater rods decreases from the inlet to the outlet and the diameter of the roller body increases from the inlet to the outlet. This arrangement allows the opening of the fibre flocks to be improved and permits a more complete separation of impurities through the bar grates.
