摘要:
In the procedure for ensuring a precisely positioned introduction of a substitute yarn in a knitting machine by means of a substitute yarn (15) which is attached by a knotter (13) to a running yarn (12), the machine is halted at the desired position for the change of yarn before or after formation of the connecting knot (16) and afterwards the length of yarn located between the knotter (13) and the yarn working position is drawn out past the connecting knot (16) and taken up to one side and the machine is only started up again when the yarn feeder (11) is feeding the substitute yarn.

The knitted fabric winding-up device is formed as an auxiliary device which can be located beneath the needle beds (21, 22) on a lower supporting cross member (10), at the front side of a flat knitting machine, from which it is removable, and by means of a winding roller for formation of the fabric package (24) is pivotable from an inner position to an outer position. The winding roller (13) can, even in the outer position, be driven by a motor located in the lower supporting cross member (10) or can be decoupled and turned by hand.

A carriage 14 is reciprocable along a needle bed of a flat knitting machine and carries a needle cam. A pair of stitch cams 12 and 13 are adjustably supported by the carriage 14 and are disposed so as to trail behind the needle cam in alternate strokes of the carriage, respectively. An adjustment mechanism 11 includes a stepping motor 38 (FIG. 3) which adjusts the trailing stitch cam 12 or 13 not only at the beginning of the respective stroke but also during the course of the stroke itself, thereby enabling the stitch density to be varied within each row of the knitted article as well as from row to row.
摘要:
A thread control device for a flat knitting machine having a housing and at least one thread brake arranged on the housing, has a spring acting on the thread brake, a flat spring web supported at one side, and a slider movable in a recess of the housing and having a foot which slides on the spring web so that a free end of the flat spring changes a force of the spring which acts on the thread brake in correspondence with a position of the slider.

Thread-tensioning and guide device provided for fastening to the needle-bed ends of a flat knitting machine has, on a stationary machine part (20), a pivotably mounted supporting arm (10) for each thread to be fed, the device parts influenced by the thread to be fed being distributed to the supporting arm (10) and to the stationary machine part (20), and, in the operating position of the supporting arm (10), parts of the stationary machine part (20) interacting with elements arranged on the supporting arm or being accessible through the supporting arm for setting purposes. This design of the device allows a favorable combination of a thread-tension brake influenced by a thread-tension regulator with a specially designed pick-up tensioner.
摘要:
A front yarn guide element (11) of the yarn stop motion (10) has the shape of a yarn guide eye (12) formed by a wire spiral into which a yarn can be introduced from the side and deflected to all sides without danger of slipping out. The yarn guide eye (12) is provided with a supporting part (17) located so as to be longitudinally movable in the housing (18) of the yarn stop motion (10), so that the spacing of the yarn guide eye (12) from the position (B) at which the yarn stop motion (10) is secured is adjustable.
摘要:
A flat-bed knitting machine has been described which is provided with needle sinkers arranged in a knitting cam system of a cam box carriage featuring several cams adjustable by means of stepping motors and having an electronic control unit, which features a storage device for controlling the stepping motors. In order to make the knitting density variable not only in the longitudinal direction, i.e. uniformly as a whole, row by row, but also in the transverse direction across the knitting with knitting machines of this type, the stepping motors are controlled by the storage device, one motor of which, in each case, is associated with a pair of needle sinkers consisting of preceding and trailing needle sinkers during the stroke of the cam box carriage and in synchronism with the individual needles.
摘要:
In the yarn-delivery device having at least one friction cylinder (11, 12) and at least one pivoting arm (15, 16) for each yarn (20) to be delivered, the pivoting arms having at least one deflecting roller for the yarn are mounted pivotably outside the friction cylinder and are so curved that they are pivotable to behind a friction cylinder (11, 12) and a plurality of pivoting arms (15, 16) for separate yarns (20) can be arranged next to one another. (FIG. 1)
摘要:
The device for monitoring the knitwear (16') of a flatbed knitting machine for falling-off exhibits several support bodies (18) having in each case a feeling lever (17) which rests against the knitwear (16') and which is coupled to a switching arm (25). The switching arm (25) is constructed as a contactless contactor and is moved during an adjusting movement of the feeling lever (17), which is triggered when knitwear (16') has fallen off, through the contact range of an electric switching device, for example a light barrier or an ultrasonic barrier or through a magnetic field area into an ineffective end position so that a control signal can be triggered only during the adjusting movement of the switching arm (25) between its end positions.
