    Abstract: In an arrangement for mixing fiber components, for example fiber flocks, especially in spinning preparation, fiber web production or the like, in which the fiber material to be supplied is conveyable into at least two weighing containers and, when weighing is complete, the fiber material is dischargeable from the at least two weighing containers onto a mixing belt, the weighing containers are arranged one after the other—seen in the direction of travel of the belt—above the mixing belt. In order that accurate weighing, troublefree production and increased throughput can be achieved in a simple manner, the position of at least one weighing container can be adjusted transverse to the longitudinal extent of the mixing belt.

    Abstract: An apparatus for advancing a sliver and sensing thickness variations thereof in a fiber processing machine includes a tongue-and-groove roll pair composed of a tongue roll and a groove roll. The groove roll is radially fixedly supported and has a circumferentially extending groove including a groove bottom. The tongue roll projects into the groove and defines, with the groove roll, a nip through which the sliver passes for being compressed and advanced by the tongue-and-groove roll pair. The apparatus further has a sensing device including a biased, movably supported sensor element projecting into the groove of the groove roll and cooperating with the groove bottom upstream of the nip as viewed in a direction of sliver advance for pressing the sliver against the groove bottom and for undergoing excursions in response to thickness variations of the sliver passing between the sensor element and the groove bottom.

    Abstract: A web weight control system and method are disclosed wherein the actual weight of fibers supplied to a carding machine (36) are measured in a weight pan (20) or while moving on a conveyor (22) by a sensor (92). the supply roll (14) is controlled by computer (A) to supply a preset weight of fibers. The weighed fibers are supplied on an apron feed (22) to a pneumatic delivery system (28). The delivery of weighed fibers by apron feeder (22) may be adjusted by adjusting the speed of an apron feed roll (50a). This maintains a prescribed quantity or level of fiber in a fiber storage chute feed (32). Pressure sensed by a pressure gauge (52) is used to indicate quantity of fiber in chute feed (32) and pressure signal (53) is fed to computer (A) for control of delivery roll (50a). Card feed roll (62) which feeds fibers in the form of a batt (35) from chute feed (32) to the carding machine is controlled by computer (A) in synchronization with the speed of the carding machine as sensed by doffer roll (68). A preset web weight signal (48) is compared to an actual weight signal (46) representing the actual weight of fibers supplied. Any difference between is compensated for by adjustment of the operation of card feed roll (62), and adjustment of fiber supply roll (14).

    Abstract: A weighing system whereby the weight of material fed into a weigh pan is detected and an electrical signal continually indicating that weight produced and used to control the feeding and dumping of material into and from the weigh pan. In one embodiment, the signal is produced by applying voltage to a wire which supports the weigh pan directly and which has a resistance which varies with the weight supported. In another embodiment, a probe detects the movement of a member attached to the weigh pan, which moves in response to changes of weight in the pan, from voltages generated in the probe by two single turn coils mounted with opposite flux paths on the member for movement with it. The signals produced are used to control the rate of feeding of the material into the weigh pan and to cut off feeding when a chosen weight is indicated. Control circuitry for weighing and dumping material in a fiber blending system is also disclosed.
