ABSTRACT:
A presser controller device of a carriage in a flat knitting machine in which the carriage comprises: cams that project from the carriage for urging selector jacks of corresponding knitting needles which are parallelly arranged on a needle bed of the traverse knitting machine; cam lift-down plates arranged in parallel therein for actuating their respective cams for upward and downward movement; holding means for holding selected ones of the cam lift-down plates in a given location; springs coupled to their respective cam lift-down plates for constantly urging them in one direction; and actuating means for pressing the cam lift-down plates for displacement while resisting the yielding force of the springs. The actuating means comprise a step motor, a sliding plate for pressing the cam lift-down plates, and a link operating means for transmitting an action of the step motor to the sliding plate so that the cam lift-down plates are moved leftward and rightward while resisting against the yielding force of and together wit the springs respectively by the action of the step motor transmitted via the link operating means and the sliding plate and thus, the cams linked with the cam lift-down plates can project outward from the carriage under control.
