Abstract: Method for separating straps and wrappings of fiber bales. A special diagonal cutting guide on the sides of the bale is proposed.

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: 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: Air guidance between a cellulose opener and a diaper machine, 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.

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: 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.

Abstract: A shaft mixer is disclosed having a number of shaft to which fibers are simulatneously supplied and drawn off again from the individual shafts at differing speeds. The drawn-off fibers are supplied collectively to a connected machine.

Abstract: The profile of a measurement roll is stored in a computer during a calibration revolution. On revolution with fiber mats to be measured, the computer reduces the measured values exactly by the measured values of the corresponding calibration profile. The measurement result obtained does not depend on the production quality of the measurement roll.

Abstract: The presence of extraneous materials such as polypropylene strings or strands in textile fiber material is detected at the bale shaver or plucker in which tufts of the textile fiber are removed from the bale by a rotary plucker head. The plucker head is received in a suction removal hood so that a strand which tends to be wound on the head will impact upon the hood and the frequency of such impact is automatically detected and, if found to be related to the frequency of rotation of the head, automatically causes shut down of the machine to enable clearing of the extraneous fiber or string from the head.

Abstract: A cutting apparatus for cutting a tying member of a bale of raw material by a cutting blade movable at a high speed against the tying member of the bale comprises a cutting blade with a cutting element having a length which is equal to a small fraction of the width of the bound surface of the bale substantially parallel to the length of the cutting blade and a cutter carriage device on which the cutting blade is mounted by which the cutting blade is movable toward the bale with a speed which is at least 3 m/sec on impact on the tying member.

Abstract: The opening device for opening pressed fiber bales, e.g. cotton bales or the like comprises opening rollers containing opening disks or needles to coact with a grate. If the opening device and the fiber bales contact each other in movement, the teeth of the opening disks or the like engage the fiber bales. To this effect, the grate rods (22,39,43) comprise an offset portion (32,40,43) extending transversely to the direction of travel (5) of the opening device (1), at least one opening disk (28;29) being arranged ahead of and/or behind the offset portion. Thus, an equalizing effect is achieved for the removal of flocks from the fiber bales.

Abstract: In the opening device for reducing fiber bales, e.g. cotton and staple fiber bales or the like, the opening rollers are arranged in a housing. The detached fibers or flocks are carried away in direction of the longitudinal axis of the opening rollers by means of a vacuum current in the housing. At the air discharge side of the housing (7) of the opening device, an air-conducting surface (17) projecting into the housing (7) is mounted above the opening rollers (8,9) and beneath the suction piece (12).
