Abstract
A circular knitting machine for knitting hosiery has a program drum which can be advanced through short or longer-pitch movements in dependence on an arrangement of removable pins located in seats around the drum. The presence, absence, and length of the pins is sensed mechanically by a control device associated with an incremental advance mechanism for the drum. The speed of the needle cylinder is also controlled in dependence on the arrangement of pins. By changing the arrangement, articles of different size can be produced on the machine.
