Abstract: A system for winding filamentary material around a cone. The system includes: a drive ring for rotating the cone and a lateral ring for supporting the cone. The lateral ring is rotatable with respect to the drive ring. The angular velocity of the cone is controlled by controlling the rotation of the lateral ring responsive to the tension of the filimentary material and/or responsive to the diameter of the cone.

Above the circular cutting saw there is arranged a shaped element so that on a part of the arc in front of the stationary cutting blade with respect to the rotary direction of the circular knitting machine it covers its teeth. Above said part of the arc of the shaped element in the path of the threads drawn by the needles there is arranged a projection for the purpose of lengthening the thread ends between the needle and the circular cutting saw.

Abstract: Device for controlling the thread guides in a circular knitting machine, particularly for manufacturing hosiery and similar goods. The machine has a grooved needle cylinder, the grooves containing needles and needle jacks. The machine also has a control drum which controls the needle jacks by selectively tipping them by control elements mounted upon the cylindrical surface of a control drum. The thread guides of the knitting machine are controlled by programming elements mounted on an outer end surface of the control drum, the thread guides being selectively driven by programming elements mounted upon the outer end surface of the control drum.

Abstract: The present invention relates to a method of and apparatus for inserting weft yarn in jet looms, in which the weft yarn is inserted by the action of an inserting fluid jet and entraining fluid jets. The weft yarn is projected by the inserting fluid jet into the carrying jet field made up of at least two opposite systems of entraining fluid jets disposed close to and in front of the reed of the loom; the weft yarn is discontinually supported inside the carrying jet field, and the carrying jet field is simultaneously stabilized by withdrawing a part of the fluid from the boundary layer of the jet field.

Abstract: Method of and apparatus for winding conical or tapered bobbins with the use of a rotating transfer element rolling under the surface of the bobbin on a rotating support element which compensate for the differences in the winding and supply speeds of the thread. The part of the thread leading from the distributor of the thread to the supply point of the thread onto the bobbin is lead onto the surface of a rotating transfer element which is in engagement with the surface of the winding on the bobbin and is angularly positioned on the support element in accordance with the direction of said part of the thread.

Abstract: Method of and apparatus for weft thread insertion in a jet loom. Fluid weft thread insertion medium under pressure is fed to the weft thread along the axis of a spiral weft thread reserve, said axis coinciding with the weft thread insertion channel of the loom. The weft thread reserve is constantly rotated at a fixed speed with respect to the main shaft of the loom. The weft thread is discharged from the weft thread reserve in the form of a rotating balloon of an up twister, the weft thread being discharge through a tube disposed along the said axis which loosely confines the weft thread traveling from the apex of the balloon toward the shed of the loom. A nozzle for discharging fluid weft thread inserting medium is disposed within the balloon close to but spaced from the apex end thereof so as to discharge said fluid into the inner end of the weft thread guide where it impinges upon the rotating weft thread in loose spiral formation traveling through said guiding tube.

Abstract: The invention relates to a thread movement sensor comprising an arm with at least one thread guide. The invention solves the problem of sensitivity of the sensor to the vibrations of the machine by making a part of the arm an element of a magnetic circuit of coil, the latter being connected to the control circuit of a knitting machine.

Abstract: The present invention relates to a grooved rotary yarn distributor for winding bobbins of cylindrical shape, the distributor having a reversible, crossing helical groove and a variable radius of the groove bottom. The distributor is intended for winding of cylindrical bobbins with a constant crossing angle of the wound yarn, the bobbin being employed in textile machines.

Abstract: A circular knitting machine for the production of plush goods by means of needles and cooperating sinkers created to form plush and plain loops. The invention improves fabric quality especially when using cotton thread to form plush loops by providing beside the sinker to form plush and plain loops, an auxiliary sinker with a nib to tighten the ready plush loops and with a notch to hold and to pull-down the plush loops from the sinker to form plush and plain loops.
