Abstract: When bringing pins (2) are engaged with the yarn carrier at the engagement portions (3a, 3b) near the center of the yarn carrier, the yarn carrier, as a normal carrier, feeds the yarn so that the yarn is applied to a knitting needle performing knitting operation by a carriage. When the bringing pins (2) are engaged with the yarn carrier at the engagement points (4a, 4b) near the rear side thereof in the travel direction, the yarn carrier, as an inlay carrier, feeds the yarn in preference to the knitting operation so that the yarn is not applied to the knitting needle performing the knitting operation by the carriage. When the projection portions (6a, 6b) of engagement releasing members (5a, 5b) are pressed by the contact thereof with the stopper, the engagement releasing members (5a, 5b) are moved backward, and slope portions (7a, 8a; 7b, 8b) push up the bringing pins (2) engaged with the yarn carrier at the engagement points (3a, 4a; 3b, 4b) so as to release the engagement.

Abstract: Needle beds are provided with needles, needle jacks and select jacks and selectors, and the selectors are provided with three butts. The front butt is made to contact the reference plane of the carriage to serve as the fulcrum of rocking. The second butt is used to withdraw the selector, and the tail butt is used to advance the selector. Two pressing cams of the carriage press the tail butt to make the selector to be attracted by a permanent magnet. Two raising cams of the carriage advance the selector to the H position and the A position.

Abstract: A knitting yarn feeding apparatus has a base body provided along the longitudinal direction of a front needle bed and a rear needle bed, and plural lace bars movable reciprocally on the base body in the longitudinal direction. Holding blocks are easily attached to and detached from the lace bars. Plural feeder tubes, are detachably fitted to each holding block. From the front end of the feeder tubes, knitting yarn is supplied to the knitting needles of the front needle bed, and the lapping motion is effected by the reciprocal drive of the lace bar in the longitudinal direction. Moreover, the knitting yarn feeding apparatus oscillates and displaces about a swing shaft by an oscillating mechanism provided beneath the front needle bed 11 and rear needle bed, and the front ends of the feeder tubes make a swing motion.

Abstract: A knitted fabric presser unit includes pressers corresponding to respective reciprocal directions and installed in a carriage. A first presser presses a knitted fabric when the carriage is being moved in a first knitting direction, during which a second presser is in a rest position. The first presser moves in conjunction with displacement in one direction of a sliding plate due to a follower engaged with a grooved cam. Similarly, the second presser moves in conjunction with displacement in another direction of the sliding plate due to a follower engaged with a grooved cam. Displacement of the sliding plate is caused by a rack engaged with a pinion fixed at a rotation axis of a motor. Movement traces of the first presser and the second presser are determined so that the two pressers are prevented from interfering with each other on movement thereof between a respective pressing and rest positions.

Abstract: 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.

Abstract: A flat bed knitting machine has two beds supported on either side of a central knitting region. The upper bed is supported on the lower bed by a series of specifically shaped needle plates which extend upward from the a grooved plate bed. The shape of the plates allows the upper bed to slide in separate movement from the lower bed. The shape of the supports also allowing for mounting and removal of the upper needle bed from the lower bed.

Abstract: 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.

Abstract: 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. Accordingly, both plain and rib knitting operations will be carried out with ease.
