In a needle bed in which plural rows of needle plate grooves are provided in a lower needle bed base, lower needle plates are inserted into the needle plate grooves, and a lower needle groove is formed between the lower needle plates, wherein a part of the lower needle plates is extended upwardly, the extended portion serves as an upper needle bed supporting member, a fixing member for stopping an upper needle bed base is provided on the upper needle bed supporting member, and an upper needle bed base is supported above the lower needle bed by the upper needle bed supporting member.

Upper needle bed support for V-bed knitting machine

The invention hereby provides a novel flat knitting machine which is furnished with a pair of needle beds in the front and rear positions each having a plurality of knitting needles aligned in parallel in such a condition in which respective knitting needles face each other, where a loop expanding member is provided on a lateral surface of each knitting needle. When transferring a loop from a delivery-side knitting needle engaged with this loop to an opposite receiving-side knitting needle, the receiving-side knitting needle is carried forward before the loop engaged with the delivery-side knitting needle is expandably opened by the loop expanding member, and then, the receiving-side knitting needle receives the loop in order that the loop engaged with the delivery-side knitting needle can properly be transferred to the loop expanding member from a hook of the delivery-side knitting needle. Next, the loop expanding member expandably opens the loop engaged with the delivery-side knitting needle. Next, the hook at the tip end of the delivery-side knitting needle penetrates a clearance between the loop expanding member and a lateral surface of the delivery-side knitting needle to engage the expanded loop with the hook. When transferring loops, the apparatus securely guides stitch/loop to the delivery position without incurring load to the stitch while closing the hook of the delivery-side knitting needle or by way of retracting the delivery-side knitting needle on the way of closing the hook.

Method of transferring loops integrated with a flat knitting machine

The present invention relates to a flat knitting machine provided with swing sinkers and presser bars which can move into and out from a space provided between two needle beds in relative relationship so that they effectively urge the loops or stitches of yarn.
