摘要： A mobile cam device (1) for commanding needles of a needle bed of a knitting machine, the device (1) comprising: at least a body (2) having at least an air inlet (3) destined to be connected to a source of compressed air, at least a first housing seating (4a) for movably housing at least a first actuator (5a) in the body (2), and having at least a first air pathway (6a) defined internally of the body (2) and connecting the at least an air inlet (3) with the first seating (4a) for moving the actuator by means of the compressed air, the device further comprises at least a first command cam (8a) movably mounted and associated to the body (2) and destined to interact with at least a needle of a needle bed of a knitting machine, and at least a first actuator (5a), movably housed at least partially in the first housing seating (4a) in the body (2) and destined to move in a controlled way the first command cam (8a). The device further comprises at least a first solenoid valve (9a) mounted and connected directly to the body (2) of the device and active directly at least on the first air pathway (6a), the first solenoid valve being configured and predisposed to selectively enable or prevent passage of air in the first air pathway (6a) such as to selectively activate the first actuator.

摘要： An air blast is utilized to close the latch of a dial needle carrying a loose loop of yarn on its shank portion. Such latch closing precludes possible snagging of the needle hook on the loose loop as it is cast off. The air blast does not directly impinge the needle or its latch but, rather, is directed away from the hook end of the needle along the longitudinal axis of the needle, wherein a low pressure area is created generally at the hook of the needle, an inrush of air to fill such low pressure area flipping the latch of the needle to a closed position. Such method of latch closing finds particular use in the circular rib knitting of cotton or wool yarn during the transfer of a loose loop from a dial needle to an associated cylinder needle.

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.
