摘要:
A method for winding up a yarn reserve on a winding tube for a bobbin. The method comprises the steps of: continuously sucking the spun yarn, causing it to move through a circular yarn guide-positioning element, removably arranged coaxially with a yarn suction orifice; removing yarn positioning element from the suction orifice while the yarn being supplied and continuously passing therethrough; positioning said element above a yarn adherence zone of tube; breaking the yarn passing through the positioning element allowing the supplied yarn end to fall down on the tube adherence zone and into guide device, with yarn end facing externally of the tube end, and forming yarn reserve turns before winding the yarn bobbin.

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.
