An electromagnetic disc type tension control in which the yarn guiding post is slotted off-center between the discs so that the yarn being tensioned is received between the discs and exerts a torsional force on the tension discs to cause the tension discs to rotate in order to enhance the dissipation and self-cleaning of the yarn finish accummulated therebetween.

Slotted disc type yarn tension control

Method and apparatus to produce a continuous filament textured yarn with unusually low crimp contractions and intermittent crimp along its length. This is accomplished by the use of an electromagnetic tension device to control the draw in the yarn being supplied to a false twist device driven at a speed to provide low false twist in the yarn being twisted. The apparatus includes a control between the electromagnetic tension control and the yarn supply package to prevent the yarn coming off the package from rotating in a full balloon path and consequently prevent entanglement of the yarn in the yarn guides to a yarn consuming machine.

Balloon control for yarn texturing machine

A direct current electromagnetic disc type tension control which has alternating current superimposed on the direct current circuit to allow the electromagnet to vibrate the tension discs in order to break the contact between the tension discs and between the tension discs and the electromagnet to lower the resistance to rotation of the discs by the yarn passing therethrough. The direct current electromagnetic tension control is an electromagnetic disc type tension control in which the yarn guiding post is slotted off-center between the discs so that the yarn being tensioned is received between the discs and exerts a torsional force on the tension discs to cause the tension discs to rotate in order to enhance the dissipation and self-cleaning of the yarn finish accummulated therebetween.

A.C.-D.C. Slotted type yarn tension control

A yarn package for a creel which employs a creel adaptor to be securely attached in position on the creel. The creel adaptor includes a spring member mounted thereto which engages the end of the yarn package to maintain the yarn package in position on the creel pin of the yarn creel.

Bobbin lock

Apparatus to provide a novel false twisted slub yarn by combining a core yarn and an effect yarn in a fluid tangling zone. The linear velocity of the effect yarn is raised to allow slubs to be produced in the combined yarn in an air jet apparatus. A baffle cage is used to prevent yarn from the air jet from interferring with adjacent air jets when an end comes down.

Air treatment jet for yarn

An improved fiber condenser for a spinning frame which is designed to provide an area for the passage of roving which has an elongated opening therein to allow slubs, etc., to pass through without breaking the roving or stretching it.
