Abstract
A device for the selection of needles in circular stocking knitting machines, comprising a lower needle (or jack) having radial deflection for each needle on the cylinder of the said machine. Selection actuators are provided for the control of the lower needles. Each lower needle includes two components: an element oscillating between an inoperative position and the operating, vertically movable position in order to control the corresponding needle and to follow the courses of upward and downward movement cams; and a toothed element which is arranged facing the oscillating element, capable of oscillations with same, but prevented from moving vertically. The toothed element always remains at the level of the selection actuators even when the oscillating element moves vertically.
Claims12
A selection device for selecting needles in circular stocking knitting machines with a cylinder, the device comprising:
- a lower needle having radial deflection for each needle on the cylinder of the circular stocking knitting machine;
- selection actuators arranged around the cylinder for control of each said lower needle to control lower needle oscillation between a released inoperative position and a deflected operating position, each said lower needle having selection teeth, said selection actuators having deflection levers for intercepting said selection teeth only when said lower needle has to move into said operating position, each said lower needle having a deflection heel for following a track with upward and downward movement cams and in which an operating selection of corresponding needles corresponds to the upward movement of said lower needle, each said lower needle being formed of:
- an oscillating element which oscillates between said inoperative position and said operating and vertically movable position so as to control the corresponding needle and to follow courses of the upward and downward movement cams;
- and
- a toothed element with said selection teeth, said toothed element being arranged facing said oscillating element and capable of oscillations with same, wherein said selection device includes means for preventing said toothed element from moving vertically, with said toothed element always remaining at a level of said selection actuators even when the said oscillating element moves vertically.
A circular stocking knitting machine selection device for selecting needles, the device comprising:
- upward and downward movement cams;
- a lower needle which is radially deflectable, a lower needle being provided for selection of each needle on the cylinder of the circular stocking knitting machine, each said lower needle including an oscillating element which oscillates between an inoperative position and an operating and vertically movable position so as to control the corresponding needle and to follow courses of said upward and downward movement cams and a toothed element with selection teeth, said toothed element being arranged facing said oscillating element, said toothed element being capable of oscillating with said oscillating element, said selection device including means for preventing said toothed element from moving vertically, each said lower needle having a deflection heel for following a track of said upward and downward movement cams and in which an operating selection of corresponding needles corresponds to the upward movement of said lower needle;
- selection actuators arranged around the cylinder for control of each said lower needle to control lower needle oscillation between said released inoperative position and said deflected operating position, said selection actuators having deflection levers for intercepting said selection teeth only when said lower needle has to move into said operating position, said toothed element always remaining at a level of said selection actuators even when the said oscillating element moves vertically.
