摘要:
A double-knit fabric having non-run and stretchability characteristics and method and apparatus for knitting the same in which multiple yarns are knit into cylinder needle and dial needle wales, in which two yarns are knit together into stitch loops in each wale, the stitch loops in adjacent wales in each course being knit of one yarn from the stitch loop in the adjacent wale in the same course and a yarn from a stitch loop in the adjacent wale from an adjacent course.
摘要:
An interlock circular knitting machine for knitting a double-knit fabric in which multiple yarns are knit into cylinder needle and dial needle wales, by two types of cylinder needles and two types of dial needles supplied by yarn carriers with multiple yarns, and controlled by a needle selecting cam system through first and second processes which cause the needles to move between high-tucking, holding, clearing and welt positions so that two yarns are knit together into stitch loops in each wale, the stitch loops in adjacent wales in each course being knit of one yarn from the stitch loop in the adjacent wale in the same course and a yarn from a stitch loop in the adjacent wale from an adjacent course.

Apparatus for removing and collecting fiber waste from a creel stand having multiple, juxtaposed creel sections including an air suction/blower blowing a first air stream across the top of the creel sections and creating a second air stream flowing across the bottom of the creel sections. An air deflector reciprocating across the top of the creel sections deflects the first air stream downwardly through the creel sections. A bottom plenum beneath the creel sections receives the air stream from the creel sections and confines and directs the second air stream to the suction/blower. A second blower blows air through the bottom plenum toward the suction/blower to assist the suction/blower in creating the second air stream. A plurality of baffles are included in the bottom plenum to provide laminar air flow therein.

A method of and circular knitting machine for producing a knit fabric having more uniform stitches including yarn feeders feeding a plurality of yarns to stitch forming instrumentalities, the spacing of which affects stitch length and which is subject to change during operation of the knitting machine, a sensor for sensing the tension in the plurality of yarns which changes with changes in the spacing of the stitch forming instrumentalities, and generating a signal indicative of the average tension in the yarns, a comparator for comparing the sensor signal with a pre-set desired tension, a convertor for converting the comparison result into a drive signal, and an adjuster adjusting the spacing of the stitch forming instrumentalities responsive to the drive signal.

A miniature multiple electrical connector consists of a plug connector and a receptacle connector having an insulating block and a metal shell. The metal shell is fixed to the insulating block by fitting anchoring protrusions provided along both sides of the insulating block in anchoring apertures of fixing tongues provided on the metal shell. When the plug connector is being inserted into the receptacle connector, the metal shell of the receptacle connector is likely to be deformed by a metal shell of the plug connector. In order to prevent such a deformation of the metal shell, there is provided means for anchoring the center of the metal shell weakest in mechanical strength to the insulating block or means for preventing application of a force to the center of the metal shell when the plug connector is being inserted into the receptacle connector.
摘要:
Fiber waste generated adjacent the knitting section of the knitting machine and adjacent yarn feeding devices of the machine is blown to a filter adjacent the top of the machine. The lint is removed from the filter by a rotatable filter cleaner and then is transported by suction to a vacuum device outside of the machine. A blower for blowing fiber waste from the yarn feeding devices is mounted upon a support ring and undergoes reciprocal movement about a path of travel defined by such ring. In one embodiment the ring undergoes rotational movement and the blowing means moves with it, while in another embodiment the ring is stationary and the blowing means moves relative to it.

An insulation-piercing connector includes a connector main body made of an insulating support block having inclined bases inclined in the same direction and a reverse direction and contacts embedded therein to expose contact tails. The contact tails are arranged in first, second, third and fourth rows in parallel with and spaced from each other and staggered or shifted from each other. A cover includes inclined bases inclined in reverse directions to those of the mating inclined bases of the connector main body and receiving slots for receiving the contact tails of the connector main body. Inclined surfaces of the inclined bases of the connector main body and the cover are curved surfaces. The first and second rows and the third and fourth rows of the contact tails are arranged in symmetry with respect to tops of the curved surfaces, respectively. The inclined bases of the connector main body and the cover are provided with protrusions for guiding the connection wires.

A contact for a connector, which includes two opposed contact elements for receiving therebetween a male contact of a mating connector. Each the contact element is provided with one or more protrusions on an opposed surface for embracing the male contact. Protrusions of the two opposed contact elements extend to that portions of the opposed contact elements which are devoid of the protrusions so as to overlap each other before the male contact is inserted between the contact elements. With this arrangement, even if the male contact is very thin, pressing force required to securely pressing the male contact by the contact elements is certainly obtained. The contact and the male contact are securely contacted without any torsional force and other forces which would otherwise be caused on these contacts.
