Abstract: An aerodynamic nonwoven formation, in which the nonwoven formation occurs in the operating range of a milling roller. The nonwoven formation takes place using a fiber opening unit, a moving screening surface with suction and a milling roller. The nonwoven-forming fibers are removed from the fiber opening roller and form a nonwoven after a flight or slide route. The nonwoven formation takes place in an area that is limited by an angle a against the direction of movement of the screen and by an angle ? with the movement of the screen relative to a section from the center of the milling roller to the screening belt.

Abstract: The invention relates to a three-dimensional structured nonwoven, which is formed from staple fibers (F1, F2, F3). In order to be able to produce such a nonwoven using simple means, the invention proposes providing groove channels (R) on at least one of its surfaces (O), which channels are milled into the surface (O) provided with the groove channels.

Abstract: A method and an apparatus for separating sewing threads from pieces of carbon fiber mats or bundles of carbon fibers using rollers covered with card clothing. The mat pieces or fiber agglomerates are broken up and separated using the different mechanical properties of the fibers.

Abstract: In order to produce air-laid non-woven fabrics with an adjustable strength ratio of the production direction and 90° to the production direction, two non-woven laying machines are set at an angle to the production direction.

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: A milling machine for working off several textile bales in a wedge shape includes a pendulum or a sliding bed for moving the bales forward in the cutting zone, wherein the bales are worked off in a wedge shape under at least two different angles. That is, the angle between the direction of the back and forth work off movement and the direction of the forward movement at the lowest work off zone is less than in the centre of the inclined work off path.

Abstract: Housing for a long optical sensor system for the inspection of material taken past the sensor in batches. The sensor is made up of several boards on which the individual photosensitive elements are placed. The boards are adjusted and attached on at least one common support. The support is located in the housing.

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 suction chamber for machines for opening and cleaning textile fibers is subdivided into at least two parts. One part of the chamber is mounted swivelably relative to the other part. Therefore, a drum of the machine and the suction chamber become easily accessible.

Abstract: The fiber opening machine has an opening drum with adjacent trough, which receives fibers from a feeding device with feeding rollers. The fiber opening machine has a suction chamber for generating an air current to remove open fibers from the opening drum. The suction chamber is defined by the output side of the opening drum and an opposing suction chamber wall which is shaped to form a biconcave space through which a current of air is passed to remove the fibers from the opening drum so that fibers are removed from the drum without nep formation at rotational speeds which are higher than those attainable without the biconcave space.
