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: A feed method of feeding a thread wound on a bobbin to a thread drawing-in apparatus through first and second suction nozzles, comprising the steps of: advancing the thread to a first position between the bobbin and the first suction nozzle, along an axis; gripping the advanced thread at the first position and then drawing the thread at the first position in a predetermined direction substantially perpendicular to the axis of a first predetermined length; gripping the drawn thread at a second position between the bobbin and the first position and also releasing the drawn thread at the first position, and then feeding the drawn thread to the thread drawing-in apparatus; gripping the fede thread at a third position between the second suction nozzle and the thread drawing-in apparatus and also releasing the thread at the first and second positions, and then drawing the thread at the third position in the predetermined direction by a second predetermined length; and cutting the thread that has been drawn by the s

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 warp-drawing apparatus for drawing a warp thread through an eye of a heddle, comprising a compression nozzle which is provided in one side of the heddle and formed with a compression passageway through which the warp thread is drawn and formed with a nozzle passageway through which compression air is injected, a suction nozzle which is provided in the other side of the heddle and formed with a suction passageway through which the warp thread is drawn and formed with a nozzle passageway through which compression air is injected, and suction means for drawing air from an exit of the suction passageway of the suction nozzle in a direction in which the warp thread is drawn through the eye of the heddle.

Abstract: A heddle transferring apparatus comprising: a heddle magazine having upper and lower magazine bars which have a plurality of heddles supported thereon; a heddle bar supporting rack having a plurality of upper and lower heddle bars supported thereon; means for separating one heddle from among the plurality of heddles and maintaining the separated heddle in a first predetermined position; a pair of heddle transferring chucks for transferring to a second predetermined position the heddle maintained in the first predetermined position; a pair of heddle receiving hooks for receiving the heddle transferred to the second predetermined position from the pair of heddle transferring chucks; a pair of heddle retaining bars for retaining the heddle of the second predetermined position in cooperation with the heddle receiving hooks; and a pair of heddle pushing bars for inserting the heddle received on the heddle receiving hooks on predetermined upper and lower heddle bars of the upper and lower heddle bars.

Abstract: A warp transfer apparatus for transferring warp threads to a warp drawing apparatus, comprising a stationary frame structure, a warp carrying frame structure for carrying the warp threads thereon which is movable with respect to the stationary frame structure and which has mounted thereon a rack extending along a direction in which the warp carrying frame structure moves, a pinion support rotatably supported on the stationary frame structure, a pinion rotatably supported on the pinion support and engageable with the rack, means for driving the pinion to rotate about an axis of rotation of the pinion, the warp carrying frame structure being transferred to a predetermined position of the stationary frame structure by rotation of the pinion, means for rotating the pinion support in accordance with upward and downward movements of the rack during movement of the warp carrying frame structure, with the condition the rack is properly engaged by the pinion.

Abstract: An apparatus for passing a thread through a member formed with an opening, comprising; a first member formed with a passageway passing therethrough movable in an axial direction; the first member comprising upper and lower parts which are movable toward and away from each other in a direction substantially perpendicular to the axial direction; a second member formed with a passageway passing therethrough, the second member and the first member being movable toward and away from each in the axial direction; a unit for interposing the member formed with an opening between the first and second members; a unit for transferring the thread to the passageway of the first member; a unit for passing the thread through the passageway of the first member, the opening in the member and the passageway of the second member by vaccum suction; and a unit for taking out the thread passed through the opening of the member from the first member.
