A novel method and apparatus to produce a novel woven fabric with a pattern integral therewith. The pattern is formed in the fabric during weaving by selectively stretching the warp yarn between the fell line and the warp beam so that the stretched warp yarn creates an open area and upon release creates an area of high density fill yarn.

Patterned woven fabric

A process to provide a patterned, laminated fabric in which an inner foam layer is embossed to hold the pattern in the outer decorative layer in position. The process continuously cold embosses the flame laminated fabric to allow continuous formation of the subject fabric at an acceptable rate of speed.

Three dimensional patterning process

An electromagnetic disc type tension control in which a spring-like member is located between the electromagnetic coil and the lower tension disc to urge the lower tension disc upward towards the upper tension disc when the electromagnet is being supplied low voltage in order to encourage rotation of the tension discs to enhance the removal of finish and foreign material accumulated therebetween.

Spring biased electromagnetically controlled 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 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 to lower the resistance to rotation of the discs by the yarn passing therethrough. The direct current circuit includes a source of high voltage and a source of low voltage and the current from the low direct current voltage source is cut off periodically and momentarily.

Continuous A.C. tension control

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.

Disc type yarn tension control

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. The balloon control basically employs a bar member under which the yarn passes as it is delivered to a yarn guide tube. The bar member prevents the yarn from rotating as it is taken off over-end from the yarn package thereby alleviating the possibility of yarn entanglement at the yarn tube.

Bar balloon control
