The invention relates to a shuttle for a weaving machine, of which the shuttle is designed to be alternately transferred from one side of a weave to the other while machine-side guiding elements are constantly intervening, with a left-hand connecting element and a right-hand connecting element for connecting the shuttle to the corresponding transfer element and to a filling (weft) bobbin. The filling bobbin is embodied to be rotationally positively drivable, with a drive that is designed for at least two impingements upon the filling bobbin, namely for either accelerating or for decelerating the dispensing of filling (weft) thread. The invention further relates to a weaving process in which such a shuttle is used.

A quick change assembly for a tire cord fabric loom utilizes a pattern of warp ends which are threaded through suitable harnesses. The pattern in the harnesses is placed in the loom and the individual warp ends are pulled back to a plurality of creel combs which are secured to the creel and which each receive and guide a group of warp strands from the creel. These warp strands are directed to the loom and are formed into the tire cord fabric having the desired pattern.

A transport device is provided which is driven by an electromotor and on which more than two bobbin supports are mounted and are movable in common such that the respective bobbin to be unwound can be brought into the required association with respect to a stationary thread eye. A thread scanning device is provided adjacent the unwound thread for detecting the thread as it jumps from the bobbin just emptied to the next bobbin. This thread scanning device is connected with the electromotor such that, when the thread scanning device responds, the motor moves the transport device to such an extent that the next bobbin is brought into the required association with respect to the stationary thread eye.

A device for reducing the otherwise minimum unthreading distance between the end of a bobbin and an unthreading guide in a textile yarn unthreading machine. The device comprises a member which defines a formed edge surface, preferably in the form of a circular disc, mounted substantially perpendicular to the axis of the bobbin and concentric with this axis. The disc is positioned between the bobbin and the unthreading guide to define a specially shaped, yarn supporting edge. The positioning of the disc is such that, as the yarn passes over the edge of the disc while being unwound, the angle formed by the straight line which joins the edge of the disc and the facing edge of the bobbin relative to said axis is equal to the half-angle of unthreading. Further the angle formed by the straight line which joins the edge of the disc to the unthreading guide, relative to the said axis, is markedly greater than the half-angle of unthreading.

A creeling device for bobbins, especially for bobbins with conical sleeves, which includes a clamping member with resilient ribs and with a limited spring stroke of the resilient ribs. Preferably the creeling device comprises a central or hub portion surrounded by an annular resilient portion radially spaced from the hub portion and provided with ribs extending in the axial direction of the annular resilient portion which latter has one end resiliently connected to the hub.

This invention relates generally to a shuttle spring for holding a yarn filled bobbin in a loom shuttle wherein the spring has a pair of opposed jaw portions for resiliently holding the bobbin therebetween. A vertical side surface of one of the jaw portions has a greater vertical width than the vertical side surface of the opposing jaw portion to effect rotation of the bobbin, when being ejected from the shuttle by the insertion of a full bobbin, in a direction so as to ensure that an adequate transfer tail of unused yarn separates from the spent bobbin. The transfer tail of yarn trailing from the bobbin is then caught by a stripping machine which completely strips the bobbin of the unused yarn.

The invention relates to a clip device on a shuttle of a loom for retaining the head of weft pirns. The clip device has a clamping jaw at each lateral wall of the shuttle and inserted between each clamping jaw and its associated lateral wall is a resilient material for permitting movement of the clamping jaws towards and away from the lateral wall.

An adjustable support for bobbins comprising a spool holder, a shaft and a plurality of holding devices. The holding devices are of such shape and are so mounted as to permit the support of cylindrical as well as conical bobbin tubes of different diameters.

ESPECIALLY SUITED FOR USE WITH CARPET TURFTING MACHINES WHICH USE A NUMBER OF INDIVIDUAL CONTINUOUS YARNS, BUT ALSO USEFUL FOR OTHER PURPOSES SUCH AS WEAVING AND KNITTING PROCESSES, THE DIRECTION OF THE TAKE OFF POINTS OF THE YARNS ARE ARRANGED ON THE RACK SO THAT THE CONVERGING TRIANGLES FORMED BY THE AXES OF THE YARN CONES ARE NESTED TOGETHER THEREBY CONSERVING A CONSIDERABLE PORTION OF THE LOST TRIANGLE OF SPACE PRESENT IN PREVIOUS CREEL DESIGNS. IN ONE FORM OF THE PRESENT CREEL ARRANGEMENT A RACK IS CONSTRUCTED FROM VERTICAL AND HORIZONTAL ANGLE IRON MEMBERS AND THE BOBBINS ARE REMOVABLY SUPPORTED ON CONE HOLDER BRACKETS BENT IN A SHAPE SIMILAR TO BICYCLE HANDLEBARS WHICH ARE WELDED IN THE MIDDLE TO A POST AND EACH HANDLE PROVIDES A MEMBER ON WHICH A BOBBIN OR YARN PACKAGE IS REMOVABLY SUPPORTED. THE DIRECTION OF THE TAKE OFF POINTS OF THE YARN IS SO ARRANGED ALTERNATIVELY SO THAT THE CONVERGING TRIANGLES FORMED BY THE AXES OF THE YARN CONES ARE NESTED TOGETHER AND IN ONE FORM SPACE IS CONSERVED WITHIN THE RACK BUT MORE AISLES ARE NECESSARY WHICH IS A MOST CONVENIENT CREEL TO SERVICE BECAUSE ALL THE DISTANCES ARE REDUCED AND IT IS EASY TO REACH EVERY POINT IN THE CREEL. ANOTHER FROM SAVES OVER 20% OF FLOOR SPACE COMPARED TO AN OLD STYLE CREEL. THERE IS NO AISLE INSIDE THE RACK AND ALL SERVICING IS PERFORMED FROM THE FLOOR AROUND THE RACK. THE YARN SUPPORT BRACKETS ARE ANGLED WITH RESPECT TO ONE ANOTHER SO THAT THE AXES OF THE YARN PACKAGE SUPPORT MEMBERS ON EACH BRACKET CONVERGE ON OPPOSITE SIDES OF THE SECTION OF THE RACK.
摘要:
A creel for supporting a plurality of spools of filamentary matter comprising a plurality of spool holders extending generally horizontally to receive spools of filamentary matter thereon, the spool holders extending generally horizontally and disposed in an arcuate array about a focal take-off element. Multiple arcuate arrays are disposed in staggered back-to-back relation to develop close packing of the arrays and provide a creel which effects a substantial saving of space while simultaneously exposing each of the spool holders for ready access for loading spools of filamentary matter thereon.
