ABSTRACT:
A lock for circular knitting machines. According to the invention, a lock or cam comprises a fixed lock element supporting or carrying cams defining the guide tracks for the knitting needle heels, causing the outgoing and re-entering movements of said needles; such cams are secured to a slider movable between extreme positions within a guide of said fixed lock element. The slider has a threaded portion engaging a first screw thread of a manually operable adjusting element for the slider stroke, which adjusting element is provided with a second screw thread in opposite direction to the former; this second screw thread screwing in a threaded seat of the fixed lock element, so that at a rotation of said adjusting element there would correspond an overall displacement of the cam carrying slider equal to the sum of the displacement of said slider relative to the adjusting element and of that of the latter relative to said fixed element.
