Abstract
An automatic positioning device for the control cams of the needle selecting cylinders on a circular knitting machine. According to the invention, the device comprises a portion fixed to the machine frame and a portion movable and rotating with the needle cylinder. The movable portion of the device comprises a cam support movable between extreme positions and cooperating with a retaining means operable by the fixed portion of the device to release, lock the cam and maintain it at predetermined positions between said extreme positions. On the other hand, the fixed portion of the device comprises a release member for said retaining means and cam positioning members, the cam release and positioning members being operated through linkages by a mechanical programming device. In known prior art devices such as U.S. Pat. No. 3,766,753, a control cam is disclosed which has several profiles. The cam is positioned in a vertical direction in order to bring a desired profile into alignment with a cam follower.
