摘要： A pick-up device for picking up a tubular knitted article from a circular knitting machine, comprising an annular pick-up body which supports pick-up elements which can slide relative to the pick-up body along radial directions. The end of each one of the pick-up elements has a seat which can engage a region of the stem of the needle located proximate to the latch of the needle on the opposite side with respect to the head of the needle. The device comprises actuation elements formed by elastic elements which act on the pick-up elements for their sliding toward the axis of the pick-up body and radial pushers which act on the pick-up elements for their sliding away from the axis of the pick-up body in contrast with the action of the elastic elements.

摘要： The machine has a rotatable needle cylinder and a casting-off sinker actuation device including a coaxial sinker ring supporting a cam and an external countercam. The needle cylinder supports a plurality of casting-off sinkers each having a heel which follows a path, extending around the needle cylinder axis, which is partially defined by the cam and the countercam. A pin is connected to the countercam and is engaged by an actuation element associated with the sinker ring and bilaterally engaging the pin. The actuation element is controllably activatable for bilaterally moving the countercam with respect to the needle cylinder along a direction having a radial component, toward or away from the axis of the needle cylinder.

摘要： Wide variations of the knitting program determined by the program drum of a circular knitting machine may be achieved by providing a plurality of rotatable program discs having peripheral seats for removable pins for determining supplementary programs and by providing followers co-operable with the program discs and linked to the means for advancing the program drum to selectively render the advancing means inoperative in dependence on the supplementary program. A driving linkage actuated by a cam track on the program drum is provided to allow relatively large angular advancement of the program drum when desired. Another driving linkage actuated by another cam track on the program drum is provided for reducing the speed of the needle cylinder.

摘要： 1,151,149. Knitting. SCOTT & WILLIAMS, Inc. 9 April, 1968 [11 1 April, 1967], No. 16982/68. Headings DIC and D1K. A method of effecting make-up on bare needles of a superposed cylinder machine comprises locating all of the needles in the lower cylinder of the machine and after opening their latches feeding a yarn so that it is fed into the hooks of the needles, the alternate needles subsequently being raised so that the yarn passes on to their shanks. The alternate needles are then transferred to the upper cylinder whereafter yarn is fed to them only and they are caused to engage the yarn and draw loops which they hold over the next three courses formed by the lower cylinder needles taking yarn and knitting. Subsequently the needles of both beds take and knit yarns the held loops being knitted in with a later course as shown in Fig. 4. Elastic yarn may also be included in the courses. The make-up is achieved by feeding yarn at a single station on a two feeder machine in which the second feeder is initially rendered inoperative but is introduced, for example, at course IX when two feed knitting is commenced. The method is carried out on a two or more feeder machine having a cam set up involving withdrawable cams for deflecting the needles into knitting or non-knitting paths. The sliders have variable length butt arrangements and the upper sliders have an additional butt to allow needle manipulation and transfer to be effected in the required manner. The machine also has adjustable verge bits 80 collectively movable by being mounted in a housing 82 secured to a tube 90 movable up and down under the dictates of a cam controlled mechanism 108 . . . 120. The cams are mounted on a bed 66 secured by a screwed tube 72 and the cam positioning is adjustable during reciprocatary knitting by a control sleeve 68 moving between limits engaged by a stop 70 secured to the sleeve. Pneumatic take down mechanism is provided and in order to deflect the air sream towards the fabric a deflector 132 also is provided pro jecting within the needle circle. Fabric camming fins 78 also assist in the take down of the fabric and the provision of humps 76 in combination with air flow and the fins provide the necessary inwardly and downwardly directed tensions to the fabric as new stitches are being formed. To assist the initial course structure by ensuring that the yarn is received in the needle hooks a latch opener comprising a nozzle which directs a stream of air against the latches to deflect them downwardly into an open position is provided adjacent the needle circle.
