Abstract: In the case of a thread braking device (B), which is intended to be used especially on the supply side of a thread feeder (F) and which comprises a thread brake (3) having a fixed passage axis (f) and having arranged thereon a shield surface (A) provided with a thread opening (22) and arranged transversely to the direction (R) in which the thread (Y) is supplied, there are provided direction adjustment means (M) for the shield surface (A), with the aid of which the transverse position of said shield surface (A) can be adjusted to supply directions (R1, R2) of the thread (Y) deviating from the passage axis (f). Even in the case of a shield surface (A) for general thread-guiding tasks, which is arranged in a stationary holding means and oriented transversely to the supply direction (R) of the thread (Y), such position adjustment means are provided so that the transverse position of the shield surface (A) can be adjusted to the respective supply direction (R1, R2) of the thread (Y).

Abstract: A manual unreeling device for a spool of wire is adapted to be pulled over the surface of the ground in a first position in which the rims of the spool act as wheels for rolling support of the device and an inverted second position where a pair of integral skids supports the device for sliding movement over the ground and holds the spool above and out of contact with the ground surface. The first position allows better control of the payout of the wire from the spool and the second inverted position is utilized when skidding of the rims on the ground because of the increasing differential between rim diameter and remaining wire coil diameter inhibits effective operation.

Abstract: A winding apparatus winds wire into a coil in an annular groove of a cylindrical body. The apparatus includes a positioning section at which the cylindrical body is set at a predetermined relative rotary position, a winding section that includes a coil wire supply nozzle to be circulated along the annular groove and a roller for pressing the wire against the surface of the cylindrical body defining the bottom of the annular groove at a position behind the supply nozzle, a tension device capable of selectively applying various states of tension to the wire in accordance with the particular process being carried out at the winding section, and an inspection device for judging whether the coil produced is in an acceptable state.

Abstract: A method for fastening a yarn end (2) on a bobbin (1), comprises placing the bobbin (1) horizontally on two spaced supports which support the bobbin along two lines parallel to the axis of the bobbin. A partial vacuum is created in a space located near the bobbin (1), the partial vacuum being sufficient to suck the non-fastened yarn end (2) into that space. The bobbin is caused to rotate in order to wind the non-fastened yarn end (2) on the bobbin. The yarn end (2) is fastened on the bobbin (1). While step (b) is being performed, the bobbin (1) is rotated at the same time in order to unwind the non-fastened yarn end (2) so that this end can engage by suction to a sufficient extent within the space located near the bobbin (1).

Abstract: A winding spool for ribbonlike or filamentary winding material includes a cylindrical mandrel which is provided at each axial end with a disk-like rim. Arranged concentrically inside the mandrel is a tubular inner hub which is connected in one piece with the mandrel at one axial end thereof. The other axial end of the mandrel is closed by a cover which is provided with a central bore for attachment of a mandrel drive shaft of a winding machine. An inner tubular member with smooth inside surface is fixedly secured to the cover in elongation of the central bore and to the inner hub for improving integrity of the winding spool when being subjected to extreme loads during winding or unwinding of the material.

Abstract: In order to form parallel windings in the longitudinal end region of the empty tube, a drive roller, which is driven at a peripheral speed adapted to the constant thread withdrawal speed provided for the subsequent formation of the crosswinding, is placed onto the peripheral surface of the empty tube, which has been lifted from the winding cylinder, and the thread, which is delivered at a constant speed, is passed to the then driven empty tube. After formation of the reserve winding, the empty tube is lowered onto the winding cylinder. The thread is displaced towards the middle of the bobbin and, by way of adaptation to the shortening of the thread run occasioned thereby and to a change in diameter possibly then brought into effect, the peripheral speed of the drive roller is altered to maintain a constant thread wind-on tension. The thread is passed to the cross-winding device, and the drive roller is lifted from the empty tube.

Abstract: The invention disclosed here is a wire reel that is designed to be used in connection with an automated wire handling system. The reel has a generally planar stiffback, and a circular flange that is releasably connected to the stiffback. The stiffback and flange together define a circular winding space for coiling a wire onto the reel. The stiffback also carries two, spaced-apart clamps which are positioned outwardly with respect to the outer perimeter of the flange. These clamps hold the opposite ends of the coiled wire. The stiffback is shaped so that it is suitable for gripping and handling by a robotic arm or the like.

Abstract: A ball tension device for producing generally uniform tension in a traveling textile yarn, particularly in combination with a yarn storage and supply apparatus of the rotating drum type. A base portion has a yarn passageway with an upwardly facing annular ball seat. A ball freely rotatably rests on the seat to apply a force to a yarn passing over the seat and through the passageway. A ball retaining portion extends over the ball at an upward spacing sufficient to allow upward movement of the ball but insufficient to allow removal of the ball. These base and ball retaining portions project transversely from a mounting portion to provide a substantial open space to permit entry of a downwardly inclined traveling yarn. The ball retaining portion is imperforate to provide a cover for the ball and seat to shield the ball and seat from accumulation of lint. Similarly, the substantial open space around the ball and seat tends to minimize lint accumulation.

Abstract: A thread winder includes a revolver on which two radially spaced mandrels are disposed for supporting thread-receiving tubes. Thread is wound onto one of the tubes located in a winding position and, when that tube is filled, the thread is transferred to the other, empty tube without interrupting the thread feed, by rotating the revolver. After the filled package is moved out of the winding position, a deflecting rod is swung to deflect the thread to a position where it can be grabbed by a transferring device. Then, the deflecting rod is swung away from the thread, and the transferring device is swung out to displace the thread toward a thread catcher disposed on the empty tube (or its mandrel), whereupon the thread is severed. A thread diverter is also swung out from the transferring device to shield the empty tube from the trailing end of the severed thread extending from the filled package.

Abstract: A transfer tail holding device is provided to hold a transfer tail formed between one weft package and an other spare weft package. The holding device comprises a holding member having at least one notch for receiving the transfer tail. Therefore, it is possible to position the transfer tail for pick-up by another mechanism.

Abstract: A thread clamping device for a textile machine includes a clamping pad which is pressed against a clamping rib by a compression spring. The spring force can be adjusted, independent of other like devices associated with the machine, by an adjusting mechanism including a slider with an inclined surface supporting one end of the spring, wherein movement of the slider alters the precompression of the spring. The clamp is normally held open by a cam which overrides the spring, but when thread tension falls below an adjustable threshold, a tension monitor automatically activates the clamp.

Abstract: A thread storage and delivery device with overhead withdrawal of thread windings deposited on a storage drum having a frustoconical outer surface.

The ring is provided with means for changing the direction of alignment of the bristles on the outer surface of the drum.
