  • Patent number: 4864694
    Abstract: An apparatus for controlling the drafting of sliver in a draw frame wherein a control arrangement generates an adjusting signal in response to sliver mass variations to correspondingly vary the sliver draft. A modifying arrangement is provided for selective manual or automatic adjustment according to any given one or more operating parameters which influence the sliver drafting, such as physical characteristics of the sliver and environmental characteristics of the textile machine, to modify the operation of the control arrangement to correct the adjusting signal and thereby to further vary the drafting of the sliver to compensate for the operating parameters.

  • Patent number: 4858276
    Abstract: A carding machine is provided with two doffer units. Each doffer unit comprises a doffer roller and an intermediate roller coordinated thereto, which rollers are shiftable into two different operating positions. In a first operating position, the intermediated roller is out of operation and the doffer roller works in a usual manner in combination with the main cylinder. In the second operating position the doffer roller is out of operational contact with the main cylinder and the intermediate roller, which has the same direction of rotation as the main cylinder, is positioned so as to transfer the fibers from the main cylinder to the doffer roller. The fiber fleeces leaving each of the doffer units may be combined to form a compound fiber fleece.

  • Patent number: 4843685
    Abstract: The invention relates to a card for the production of a nonwoven fabric web. The object is to provide a new card enabling a high production rate and the manufacturing to be interrupted without any breaks in the web itself. The card comprises e.g. three main rolls (12, 17, 20), whereby slower transfer rolls (15, 16; 18, 19) acting as working rolls as well are provided between said main rolls. At least one flatting roll (23) is provided after the last main roll (20), from which roll (23) the fibers are advantageously transferred onto a conveyor wire (29) by means of an aspiration roller (28), said wire passing the fiber material web to further treatment.

  • Patent number: 4843684
    Abstract: A system and method for cleaning and feeding textile fibers is disclosed wherein supply units (A) include a cleaning machine (B) fed by a batt forming machine (C) which includes a reserve chute (42) and a formation chute (44). The reserve chute and formation chute are partitioned whereby a serial flow of fiber laden air may be utilized to deliver fibers to a number of the supply units connected in series. Each supply unit (C) may feed a parallel line (10, 12, 14) of card machines (16). Each card machine (16) is fed by a vertical chute feed (18) to which a fiber delivery air flow is delivered from supply units (60, 62, 64). In this manner, a first fiber batt of uniform density across its width is fed to the cleaning machines. The fibers are more uniformly fed and separated to provide more uniform opening and cleaning of the fibers. The individual and cleaned fibers are fed to a vertical chute feed wherein a second fiber batt is formed for feeding to the textile cards.

  • Patent number: 4831691
    Abstract: A compact carding apparatus is disclosed which includes a pair of upstanding carding cylinders (B) and (C) carried in a self-standing manner on a base frame (260). Cylinder (C) is carried generally atop cylinder (B) by mounting plates (272, 274) which allow radial movement of cylinder (C) to yield to large lumps passing between the cylinders. A chute feed (10) and coiler (192) are uniquely combined with the component arrangement in a minimum of space and in a mobile construction so as to permit movement of either the chute or coiler away for access to the apparatus. The compact upstanding arrangement provides for mounting of a number of carding elements mounted about the two cylinders which include stationary plates (40, 42, 44, 46) on cylinder (B); and revolving flat assembly (E) and stationary carding plates (96, 123) on cylinder (C).

  • Patent number: 4827574
    Abstract: This invention relates to a device for removing short fibers from a mass of ibers. A pair of perforated cylindrical bodies are opposed to each other with a predetermined spacing defined therebetween, and static electricity is applied across the perforated cylindrical bodies. A suction-wise removing device is installed in at least one of the perforated cylindrical bodies. The initial end of a transfer conveyor is located on the surface of one perforated cylindrical body adjacent the opposed region. Short fibers contained in the mass of fibers fed to the opposed region by a feeding device are drawn into the suction-wise removing devices through the through holes in the cylindrical bodies by the action of electrostatic force and suction air currents. The mass of fibers having the short fibers removed therefrom are oriented by electrostatic force and transferred by the conveyor while being maintained in this oriented state.

  • Patent number: 4823440
    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).
