Abstract: A method and a device for the automated transport of weaving accessories is disclosed. A device is provided which has at least one rail and at least one rail carrier. The at least one rail carrier carries the weight of the at least one rail, on which weaving accessories can be movably disposed in the longitudinal direction of the rail. The method is characterized in that the at least one rail carrier is displaced relative to the at least one rail, in the longitudinal direction thereof, in order to move weaving accessories disposed at the rail along the rail in the longitudinal direction thereof.

Abstract: A method is described of drawing a pre-oriented multifilament yarn (POY yarn). Hereby the multifilament yarn is fed from a delivery godet, around which it is wrapped, at a first velocity into a main drawing zone and removed from the main drawing zone at a second velocity by a drawing-off godet around which it is wrapped. The drawing in the main drawing zone takes place between the delivery godet and the drawing-off godet whereby the drawing-off godet is heated to a temperature of between 160.degree. C. and 240.degree. C. The first and the second velocities are so adjusted with respect to each other that the second velocity is 70% to 180% greater than the first velocity.

Abstract: A dropper separating mechanism comprising droppers each having an asymmetrical mountain position at an upper end thereof and alternatively superimposed in a first direction so that the asymmetrical mountain portions of two adjacent droppers do not overlap each other, a pushing member provided in a rear side of the droppers to push the droppers forward from the rear side, a pair of movable pawls provided so that they are movable in a second direction perpendicular to the first direction, the pair of movable pawls also being oscillated between a first position in which the mountain portion of a foremost dropper of the droppers is limited to move forward and a second position in which the mountain portion of the foremost dropper is separated, and a fixed pawl to limit a forward movement of a lower end of the foremost dropper.

Abstract: A dropper random-separating mechanism comprising a plurality of dropper rows arranged in parallel, a plurality of pairs of separating pawls corresponding in number to the plurality of dropper rows, each pair of separating pawls being adapted for separating a foremost dropper of the corresponding dropper row so that a predetermined dropper separation space is formed between the foremost dropper and the following droppers of the corresponding dropper row, a plurality of cams provided on a common rotational shaft, each cam being adapted for driving the corresponding separating pawl, a plurality of power transmission units provided between the cams and the separating pawls for forming power transmission paths between the cams and the separating pawls, a drive unit for driving the common rotational shaft so that one separating pawl of the plurality of pairs of separating pawls is actuated by the corresponding cam, and a regulating unit for connecting and disconnecting the power transmission paths.

Abstract: The device serves to manipulate the healds or drop wires from their separation from a stack via the drawing-in of the warp threads up to the transfer to supporting members provided for arranging in a weaving machine and it contains holding devices for accepting the separated healds or drop wires and for positively transporting them to a drawing-in station and a transfer station, positioning elements arranged in the area of the drawing-in station, and transfer devices, arranged in the area of the transfer station, for transferring the healds or drop wires having a drawn-in warp thread to the supporting members.Consequently, only a single type of manipulating arrangement is required for manipulating the healds and drop wires from their separation up to the transfer to the supporting members. That results in a substantial reduction in potential sources of error and thus in the susceptibility to trouble.

Abstract: The technical field of the present invention relates to an apparatus for automatically threading a warp through the eye of a heddle. In a conventional automatic warp threading apparatus, a drawing-in needle equipped with a hook is delivered out through the eye and is pulled back after hooking the warp so as to thread the warp through the eye. For this reason, the eye is likely to be damaged and a defect is likely to occur during weaving. The automatic warp threading apparatus of the present invention warp threading apparatus of the present invention clamps the warp (Y) with finger members (18, 18') disposed on a thread feeder (5) and a jet nozzle (20) fitted to the finger members (18, 18') ejects a gas so as to thread the clamped warp (Y) through the eye. Accordingly, the eye is not damaged and weaving can be made advantageously.

Abstract: A heddle magazine comprising a pair of first magazine bars having carried thereon a plurality of heddles which form a first heddle group; a pair of second magazine bars disposed in parallel relationship to the first magazine bars and having carried thereon a plurality of heddles which form a second heddle group; a stationary magazine support having the first and second magazine bars stationarily mounted thereon; and means for removing the heddle one by one selectively from the first and second heddle groups and positioning the removed heddle into a predetermined position.

Abstract: A process for manipulating fallen warp thread detector drop wires and revealing their location includes gripping and rotating a fallen wire, while spreading adjacent wires of the pack apart by a spreader and raising the fallen wire above the pack. Apparatus for gripping, rotating, spreading and lifting is disclosed.

Abstract: In a device for individually separating heddles and to subsequently draw-in warp threads into the heddle eyes using advancing and retracting needles, the heddles require being moved into a precisely defined position of draw-in. Rest means with a serrated profile are provided, which receive the individually separated heddle by means of a pressing finger in such a manner that the heddle rests against one of the ramps of the sawtooth profile. The heddle is so rotated in the process that the aperture of the heddle eye is placed in a precisely defined position and furthermore practically transversely to the path of the draw-in needle. The drawing-in of the warp threads is thereby made substantially simpler and more reliable.

Abstract: Apparatus for detecting absence or misalignment of heddles at the drawing-in position on a warp drawing machine by photoelectric means. The detection of such a condition is employed to stop the operation of the warp drawing machine until the condition is corrected.

Abstract: Process and apparatus for producing and the resulting nonwoven fabric adaptable for use as blankets and the like is characterized by increased production speed resulting in a more economical fabric, as follows. A bottom layer of at least one carded web is deposited with the fibers thereof oriented in the lengthwise direction on a moving conveyor driven at the same speed of travel as the carded web is produced. A reinforcing middle layer is preferably formed of a plurality of yarns cross-lapped onto the bottom layer for orienting the yarns in generally the widthwise direction. A top layer of at least one carded web is deposited onto the middle layer with the fibers thereof oriented in the lengthwise direction.
