Abstract: An automatic leasing machine for a warp beam on which a warp delivered from the warp beam is grouped into separate warp sheets of different colors, and warps from a warp sheet in turn are subsequently separated from the sheet, passed through a gap between a pair of warp leasing cords which alternate positions once per one warp passing, and fixed by means of bonding tapes. The foregoing operation is repeated cyclically in a fully automatic fashion for all warps in the warp sheet in accordance with a given stripe design of the yarn dyed fancy fabric to be woven.

Abstract: A control circuit for apparatus stretching a web between intake, discharge, and intermediate pulling stations (20-1, 20-2, 20-3). The circuit includes a first signal generator (32) for providing a signal to the intake discharge station (20-1) corresponding to the desired speed of the web at that station. A multiplier (40) alters the first signal in accordance with the amount of overall stretching, or stretch ratio, desired in the apparatus. The multiplier provides a second signal to the discharge station (20-3) corresponding to the speed of the web at the discharge station necessary to obtain the overall stretching. A second signal generator (48-66) subtracts a selected amount of the difference between the first and second signals from the second signal to provide a third signal to the intermediate pulling station (20-2) that distributes the overall stretching in the apparatus between intermediate zones formed by the adjacent pulling stations.

Abstract: An apparatus for the steam conditioning of lengths of textile fabrics includes a frame carrying a fabric spreader for spreading of the fabric in a spreading zone, steam boxes for application of steam to the spread fabric within a steam zone, a cooling zone, and fabric advancing mechanism for advancing the fabric through the steam and cooling zones. A duct system encloses the steam boxes and, in conjunction with one or more blowers, evacuates steam upwardly and downwardly from a region adjacent the steam boxes thereby confining the steam zone to the region between the discharge sections of the steam boxes and preventing the migration of steam to areas upstream and downstream of such steam zone.

Abstract: A portable fastening tool of the type incorporating torque and angle sensors is connected to a data processor which analyzes the torque and angle sensings and generates a shut off signal to terminate tightening. The tool is powered and includes a fluid motor typically energized from a remote source of high pressure air. The data processor is energized by either a battery or an AC source. Termination of tool operation is effected by energizing a solenoid in response to a shut off signal generated by the data processor. In a battery operated embodiment, tool operation is initiated by manual depression of an operating lever while tool termination is effected automatically in response to the shut off signal. This mode of operation reduces the number of required batteries, prolongs battery life and reduces the number and size of electrical components in the tool.

Fluid is supplied to the conduits from a suitable source, and a mechanism is provided for controlling the velocity and direction of travel of a multifilament yarn into and out of the yarn passageway, most desirably in a traversing movement.

Abstract: An apparatus for depositing a moving fiber strand as folded loops into a storage means includes means for taking off a strand arriving at high speed from a delivery means, an intermediate depositing means for decelerating the strand and for releasing the strand in a folded condition so that the strand will deposit by free fall into a storage means. In the intermediate depositing means, the strand is deflected into a zigzag position to form a plurality of folded loops by guide elements provided in the depositing means. These guide elements are arranged so that the size of the loops constantly are increased during the movement of the strand through the depositing means so that unnecessary tension on the strand is reduced or avoided. Additionally, a conveyor drum is provided beneath the intermediate depositing means for further decelerating the fall of the folded loops into the storage means, e.g., a can or like container.

Abstract: In order to pivot lifting forks and press or contact roll arms, there is employed a single cylinder unit acting by means of a piston rod upon a crank arm of a shaft member. Rotation of this shaft member causes, by means of the press roll arms connected rigidly for rotation with such shaft member, pivoting of a press or contact roll. A lever which likewise is rigidly connected for rotation with the shaft member is hingedly connected with a pair of brackets at whose other end there is located a guide roller or roll which travels in a slotted guide of a guide lever carrying one of the lifting or lift forks for the lifting-in and lifting-out of the warp beam. The other lifting fork is carried by a second analogous guide lever. Both of the guide levers are operatively connected with a pivotal shaft.

Abstract: A method of producing surface height patterned materials by application of streams of pressurized, heated fluid into surface areas of a relatively moving material having thermally modifiable surface components. The heated fluid streams are selectively activated and deactivated in accordance with pattern information to strike selected surface areas of the material to thermally shrink and compact the surface areas by a desired amount. Heated fluid stream flow is controlled by use of cooler pressurized fluid which is selectively directed into the heated fluid stream flow to block the same from striking the surface of the moving material. The temperature of selected of the heated fluid streams striking the material is controllably varied by rapidly introducing small amounts of cooler fluid which blend into the heated streams to correspondingly vary the height reduction of the surface of the material.
