PROBLEM TO BE SOLVED: To provide a torchon lace machine which halves impact noises produced on the energizing of a solenoid and can always accurately perform patterning. SOLUTION: This torchon lace machine is characterized by disposing a clutch 9 for connecting a rotor metal 1 to a rotor-driving shaft 6, when upward moved, and separating the rotor metal 1 from the rotor-driving shaft 6, when downward moved, a fork member 12 which holds the clutch and is downward energized with a spring 13a, a slide shaft 14 horizontally slidably penetrating the back plate of the fork member , the first cam 15a which acts on a cam follower 14a disposed on the inner end side of the slide shaft to upward displace the fork member through the slide shaft, a solenoid for pushing the slide shaft to make the cam follower to approach the operation area of the first cam, the second cam 15b for pushing back the cam follower to the outside of the operation area of the first cam, and the third cam 19 for reinforcing the force of the spring for downward energizing the fork member. Patterning can always accurately be carried out by the operation of the third cam 19. COPYRIGHT: (C)2005,JPO&NCIPI
