Abstract: Air guidance between a cellulose opener and a diaper machine is characterized in that the air used for removal and conveying to the diaper machine is guided back to the opener and is again used for fiber conveying. Specifically, air guidance achieved by designing the fiber opener in such manner that the exhaust air from the diaper machine which has conveyed the fibers to the diaper machine is guided back to the fiber opener and serves to remove the fibers from the opener roller.

Abstract: An apparatus and method for detecting defects in the cover sheets used to manufacture diapers is disclosed. A linear sensor is used to detect defects in the cover sheet web before it is combined with the absorbent material to form a diaper. When a defect is detected, the manufactured diaper containing the defective cover sheet is ejected from the line after a delay which is dependent on the speed of the process.

Abstract: The invention relates to a process which enables colored foreign bodies to be detected in continuous fibre transport and removed therefrom. A stream of fibres is examined for foreign bodies by color sensors (11). If the color differs, a control system (12) activates compressed air nozzles (13) and removes foreign bodies (17).

Abstract: The invention relates to a process which enables foreign bodies to be rapidly recognized and filtered out of fibre processing lines. A stream of fibres is inspected by color sensors. If foreign bodies are detected in the flow of fibres, they are blown out by compressed air nozzles (13). The inspection and filtering out can be performed with continuous operation, and purposeful filtering out blows only a few foreign bodies out with the fibres.

Abstract: Continuous belt weighing machine for fibre tufts. The fibre tufts are opened by an opening unit and drop onto a transport belt with weighing cells. The speed of the transport belt is constant, the speed of the feed cylinders is varied in accordance with the measurements.

Abstract: Process for the reduction of fiber bales. The fiber bales are set up in several long parallel rows and are reduced by a reducing element travelling along the rows of bales. The reducing element reduces the material in closely adjoining, overlapping paths. The individual offset width may be less than the bale length and several paths can be reduced at the same height level.

Abstract: A bale of fibrous material bundled by metal hoops is pressed against an elongated guide, with at least one sensor disposed at the guide for producing signals in response to the presence of metal, a parting device adapted to sever a hoop being displaceable along the guide, and a control system operatively connected to the parting device and receiving signals from the sensor and in response to analyses of the signals, positioning and triggering the parting device to sever a hoop.

Abstract: A uctting mechanism for an apparatus for cutting and mixing fibers from a plurality of fiber bales arranged in a row includes a grid between the fiber bales and a cutting member having at least one cutter roller mounted at one of its ends, wherein the grid surrounds the cutting member at least up to the height of the axis of each of the cutter rollers provided.

Abstract: A fiber-bale mill comprises a cutting device which is movable over a row of fiber bales. A collector passage is open on top below the cutting device which travels to and fro. An air passage in a cutting device through which the cut fibers are drawn from the vicinity of the cutting mechanism communicates with the passage. A cover strip at least partially covers the top of the collector passage to maintain a reduced pressure therein. Guide rollers for the cover strip are provided on the cutting device, to lift the cover strip from the collector passage at the location, at which the air passage opens into the collector passage and guide the cover strip over the portion of the air passage opening into the collector passage.

Abstract: A feeding device for flocculent fiber material, e.g., cotton, synthetic fibers, etc., to processing machines, such as carding engines, etc., including an inlet which feeds fiber material through an intake roller and an opening roller into an inlet end portion of a duct, the duct having an outlet end portion at which are located take-off rollers for feeding the fiber material from the duct, the opening roller having a width corresponding to the predetermined width of the duct inlet end portion, and a transverse air current blower extending the predetermined width of the duct inlet end portion and the opening roller, the transverse air current blower being positioned above the duct inlet end portion and having an outlet directed downwardly into the duct inlet portion, and the transverse air current blower being operative at low air pressures and high air throughput.

Abstract: This disclosure relates to a control device for opening fiber bales arranged in a row including a carriage movable along a horizontal rail and carrying a slide which is vertically reciprocal with the slide carrying grabbing fingers which can both grab and release a fiber bale, such as a pressed bale of cotton, and a pneumatic control circuit for pneumatically oscillating the carriage, operating the grabbing fingers and moving the slide up and down, the pneumatic control system also including a program wheel carrying a plurality of contact cams which operate a valve to initiate the cycling of the device and a pneumatically operated ratchet for indexing the program for appropriately cycling the control device and moving the fiber bales as desired.
