A knitting machine includes a take-down assembly that includes a first take-down roller and a second take-down roller. The first take-down roller is configured to rotatably contact and apply tension to a first portion of a knit component. The second take-down roller is configured to rotatably contact and apply tension to a second portion of the knit component. The knitting machine further includes a first actuator that actuates to selectively adjust tension applied by the first take-down roller on the first portion of the knit component. Furthermore, the knitting machine includes a second actuator that actuates to selectively adjust tension applied by the second take-down roller on the second portion of the knit component. Additionally, the knitting machine includes a controller that is operably coupled to the first actuator and the second actuator to selectively and independently control actuation of the first actuator and the second actuator.

A take-off element (10) for the gentle treatment of thread and for simple handling comprises two parts (11, 12), wherein at least one of said parts is arranged so as to be adjustable in longitudinal direction relative to the other. Whereas one of the parts 11 has a longitudinal slit for receiving a thread, the other part is provided with a head (34) extending on one side away from the shaft (35), the head being movable from the outside to the thread-receiving opening (26) in order to close the opening and away therefrom in order to clear the opening. The head (34) has an oblique surface (37) which is disposed to close the thread-receiving opening (26). The new take-off element (10) does not have a hook and thus does not exhibit any problem regarding process reliability. Its part (12) has a robust slider head, thus avoiding potential deformations on the head. Considering process reliability, the take-off element (10) permits a perfect insertion and removal of the comb thread (25) of a knit fabric.

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.

The draw-off mechanism for a flat bar knitting machine having needle beds includes a pair of driven feed rollers arranged axially parallel to each other and located adjacent to the needle beds under a gap between the needle beds; a pair of pivoting levers, each pivoting lever being two-armed and having a feed roller mounted at one end thereof and an adjustable stop device for setting a minimum spacing between the feed rollers located at another end of each pivoting lever remote from the feed rollers; and a device for adjusting an initial tension on at least one of the pivoting levers to urge the pivoting levers closer together, so that the driven feed rollers can cooperate with each other and act on a workpiece running between them.

The device comprises drums, which are coaxial and supported by an axle, located below needle beds subjected to a constant torque acting with springs being provided inside the drums as a mechanical connection between them and the axle.Two pressure rollers for each drum are fitted to a number of arms mounted on a bar and holded in contact with the related drum, while electromagnets are provided to rotate one of the rollers by a predetermined amount in order to cause the related drum to be rotated in in synchrony with the formation of a corresponding portion of the last row of the fabric, that runs between the row of drums and related pairs of pressure rollers.

A fabric draw-off arrangement for flat knitting machines has a driven fabric draw-off member consisting of a plurality of roller elements and pressure rollers of a fabric pressure member associated with the roller elements which are mounted on a common rocker shaft and are adjustably and resiliently pressable against the respective roller element. In order during knitting to achieve automatically adjustable reproducibly uniform knitting draw-off, the pressure rollers are together pivotable by motor means into variable end positions and are pivotable from these positions and the pressure force of each pressure roller is individually adjustable by motor means.

A device for controlling the tension of the knitted fabric includes two parallel rows of rollers, which are supported by two plane surfaces mounting two needle beds upon which a carriage is able to move longitudinally and alternately.The rows of rollers are located beneath the needle beds with the rollers of the first row, able to turn in a single direction, being in contact with the corresponding rollers of the second row, thus creating a series of independent pairs of rollers between which the knitted fabric is inserted.Each pair of rollers is moved by a rod, mounted on the second plane surface, featuring a heel upon which moving cams act determining the consequent rotation of the corresponding pair of rollers, while fixed cams, acting upon the heels, return the rods to their initial position.

This describes a fabric take-down device (11) for flat knitting machines which is provided with a driving motor (12) and an associated adjusting device (13) to set the torque of the driving motor (12) which determines the take-down pull through the motor current.In order to provide in a fabric take-down arrangement (11) of this character for a substantial starting and controlled pull, and in particular to cater for a finely-sensitized regulation even in the area of small torque values, provision is made for the adjusting device (11) to be constituted by a motor-current regulating system (26) which is provided with inputs (27, 28, 33, 34, 39) for setting the target figures and for at least one actual value taken from the driving motor (12), and the regulating system (26) further has an input (32) for an augmenting shift pulse for a short-term increase in the torque of the driving motor (12) where there is a small target tongue (FIG. 1).
