Method for controlling the rotation of a lower cylinder (2) and a upper coaxial counter part (3) of a circular knitting machine, method comprising the steps of:
- driving with a first electric motor (M 1 )the rotation of the lower cylinder (2),
- driving with a second electric motor (M 2 ) the rotation of the upper counterpart (3),
- detecting the angular position (Õ 1 ) of the lower cylinder (3),
- detecting the angular position (Õ 1 ) of the upper counter part,
- controlling electronically the rotation of the first (M 1 ) and second (M 2 ) motors by determining of a first set-point S 1 for the first motor and a second set-point S 2 for the second motor according to:
- the main set-point S provided by the knitting program,
- the difference between the detected position Õ 1 of the lower cylinder and the detected position Õ 2 of the upper counter part,
- and eventually the desired phase shift ¾ between the lower cylinder and the upper counter part provided by the knitting program. Knitting machine implementing such method. |
