A position to form a stitch loop hooking portion is biased toward a base portion of a transfer jack from a center of a gap between needle beds. Therefore, the effective width of a tip portion of the transfer jack with respect to a height of a hook portion of a knitting needle is increased when the knitting needle enters into the stitch loop from a direction of the base portion of the transfer jack.

Transfer jack and weft knitting machine having the same, and stitch transfer method using transfer jack

When a loop is transferred from a transfer jack to a knitting needle of a lower needle bed, a needle hook ( ) of the knitting needle ( ) is inserted into the loop ( ) retained on the transfer jack ( ); then the transfer jack is moved forward so that the loop can be pushed to be placed in an advancing and retracting track of the needle hook of the knitting needle; and the slider ( ) is moved forward so that the needle hook can be closed by the slider to capture and keep the loop in the needle hook, whereby possible occurrence of drop stitch is prevented to ensure that the loop is transferred from the transfer jack to the knitting needle.

Weft knitting machine with transfer mechanism and transferring method

There are provided a transfer jack ( ) which is structured so that when a loop retaining portion ( ) is advanced to an advanced position over a needle bed gap ( ) between front and back needle beds ( ), the loop retaining portion can be held in such a manner as to swing between its raised position and its lowered position; transfer jack holding means ( ) for holding the loop retaining portion in its raised position at least as high as a level to avoid interference with knitting members arranged on the needle beds ( ) while the needle bed is racked, when the loop retaining portion ( ) of the transfer jack ( ) retaining a loop ( ) thereon is in the advanced position; and transfer jack controlling means ( ) for controlling the transfer jack holding means to selectively hold the loop retaining portion ( ) of the transfer jack ( ) in its raised position and release it from its held state.

Weft knitting machine with transfer mechanism

A flat knitting machine comprising a transfer jack bed ( ) holding transfer jacks ( ) in such a manner as to freely advance and retract, wherein when a loop is transferred from the transfer jack ( ) to the needle ( ), the loop retaining portion ( ) of the transfer jack ( ) put in its advanced position is moved down to its lowered position, first; then, a back side ( ) of a needle hook of the needle ( ) is made to go into the loop ( ) retained on the loop retaining portion ( ) of the transfer jack ( ); then the loop retaining portion ( ) is raised up to its raised position; and thereafter, a front side ( ) of the needle hook of the needle is made to go into the loop, whereby the transfer of loop can be ensured with a reduced burden on the loop in the transfer of loop through the use of a common track for the needles of the front bed ( ) and for the needles of the back bed ( ).

Weft knitting machine with transferring mechanism and transferring method

A flat knitting machine having a transferring mechanism using transfer jacks wherein the transfer jacks each have (i) at a front end thereof a loop engaging portion; (ii) at a rear end thereof a selected engaging projection extending rearwardly from a rear end of the jack groove when the transfer jack is in its retracted position; and (iii) at an upper edge of a jack body thereof an advance-and-retreat controlling butt which extends from an upper surface of the jack groove and is engageable with the transfer jack operating cam to control the transfer jack to move forward and backward; and

Flat knitting machine having a transfer jack transferring mechanism

A method and apparatus for knitting a cross pattern texture on a flat knitting machine comprising front and rear needle beds, each needle bed having a plurality of needle grooves parallel and equally spaced along a length of the needle beds and each of such grooves having a needle therein, needle cams for selectively advancing and retracting the needles in the needle grooves transverse the needle beds for forming knit stitches on the needles in yarn fed to the needles as such needles are advanced and retracted in the needle grooves, a transfer jack supported above each of the needle beds and each moving transverse of the jack beds in jack grooves in the jack beds, a transfer cam for selectively moving each of the transfer jacks in the jack grooves, a lift cam protruding into a cam groove of the transfer cam and means for moving the lift cam into and out of the cam groove, wherein each of the transfer jacks is retracted in the jack groove or remains forward depending on the lift cam's position in the cam groove of the transfer cam.

Method for knitting a crossing pattern and an apparatus for knitting a

A transferring jack for a flat knitting machine for entering the stitch expanded portion of a stitch to be transferred to allow the distal end of the knitting needle to which the stitch is to be transferred to enter such stitch, such transferring jack having a distal end from a stitch engaging portion, a stitch transferring aperture formed with an elastic plate at the stitch engaging portion and a guide face formed by outwardly bending the elastic outwardly at a bottom edge of the jack transferring aperture for guiding the knitting needle to enter the stitch transferring aperture.

Transferring jack of a flat knitting machine

A flat knitting machine with a transferring mechanism comprising a pair of needle beds arranged facing each other to form an inverted V-shaped form in a side view and to form an aperture between adjoining end portions of the needle beds, knitting needles arranged in needle grooves formed on the needle beds, a yarn feeder arranged above the aperture between the needle beds, each carriage being reciprocally movable on each of the needle beds and having cam surface on a lower surface of the carriage for moving the knitting needles forward and backward, each transferring jack bed is supported by a supporting member above each of the needle beds, a transferring jack having a transfer jack selected member and arranged swingably and movably forward and backward in a jack groove formed on each transferring bed, and a transfer jack selecting unit acting on the transfer jack selected member and arranged at an edge portion of the carriage, which is adjoining to the aperture. The needle bed and the transferring jack bed are relatively movable.
