Abstract: A shuttle spool and a method for its producing, the spool being for a shuttle in a weaving machine wherein the yarn (thread) is wound onto a pirn which is rotated by rotational devices during the winding. A yarn-trapping device is provided at one end of the pirn, and the pirn with the yarn-trapping device is positioned in the rotational devices. The yarn on the pirn is being wound to form the spool, and after the winding-on of the yarn has been completed, an emerging yarn part is brought into cooperation with the yarn-trapping device for fixing the emerging yarn part.

Abstract: An adjustable knot-disalignment device for use in a loom in which weaving is effected by passing a shuttle containing a cop around which a weft yarn is wound between upper and lower warp yarns. The adjusting device includes a disk-shaped reel provided with a circumferential channel for accommodating a wound thread thereon, a thread holding device projecting outward of the circumferential channel of the reel for holding threads and a hooking device for hooking the threads held by the holding device and rotating the threads, thereby winding the threads onto the circumferential channel of the reel. By controlling the number of times the thread is wound around the disc-shaped reel, the knots which connect the threads from two different cops may be made to be disaligned in the woven fabric.

Abstract: A controlling and supervising system for a loom controlled with a network of computers connected in a network. A host computer provides data files containing dispatching data and production instructions for various units and devices. A data-communication personal computer connected to the network receives data transmitted from the host computer in file and loads the received data into the various units and devices via the network. A plurality of supervisory personal computers are provided for storing the data from the data-communication personal computer and further downloading the data as required, with the addition of operating data, and also supervising predetermined operations and functions of the loom in accordance with signals received from the loom.

Abstract: The weft bobbin changer comprises a bobbin turntable comprising a delivery bobbin and at least one reserve bobbin. A sensor continuously monitors the quantity of yarn on the delivery bobbin. Only when the adjustable minimum quantity of yarn on the delivery bobbin has been reached is a piecing-up operation performed to join the yarn of the deliver bobbin to the yarn of the reserve bobbin. The yarn of the previous delivery bobbin being severed between the delivery bobbin and a yarn joint which has been or will be made is such that the previous reserve bobbin becomes the new delivery bobbin. The minimum yarn quantity for high-quality fabrics can therefore be greater than previously without loss of material and the yarn residues left on the bobbin can be further processed in lower-quality products.

Abstract: The present invention relates to methods of and apparatus for threading the weft thread carriers and may be most effectively used on travelling-wave looms. In this method, the weft thread is introduced into a thread tensioner while the last coil thereof is being wound with gripping before a straight section is formed, after which the thread is shifted by being unwound from a bobbin in the direction of feed, with the carrier admitted into the looming-up zone at this time, this shifting being maintained up to the moment of separation of the straight section from the coils. In an apparatus for realizing this method, there is provided a stationary cam for jaws located in a central angle of a disk within a sector limited by a region of divergence of mechanical trajectories of the disk and a conveyer and a region corresponding to the last turn of the threadguide around its axis which is close to the axis of rotation of the disk and shifted relative to the axis of symmetry of the carrier spool.

Abstract: Winding device for the filling-yarn bobbins of shuttles of a multi-shed loom having a filling station, which device has a yarn guide rotating on a circular path and conducting a filling yarn, as well as first means for the successive movement of the empty bobbins into the plane of the circle defined by the rotation of the yarn guide.

Abstract: A device for supplying a textile or metallic thread to a processing device. The thread issuing from a storage bobbin is wound tangentially on a storage body and is unwound endwise therefrom beneath a resilient brake ring which abuts a conical support surface on the storage body. The brake ring can be adjusted in the axial direction of the storage body relative to the support surface by means of an adjusting means which can be actuated in response to the thread tension.

Abstract: The magazine tip guide of an automatic loom filling winder is subjected to constant pounding by the quill tip support as quills are transferred into the shuttle. Eventually a section is broken out of the magazine tip guide and the replacement of this component and its refitting on the loom winder are costly and time consuming. To avoid the necessity for replacing the entire tip guide, a simple and economical part is installed between the outer side of the tip guide and the rockable quill tip support, and this repair or replacement part has a slot which registers with the slotted portion of the magazine tip guide which has been fractured. The normal operation of the magazine tip guide and quill tip support is not interfered with by the invention.
