Abstract
An improved magnetic pattern control system for circular knitting machines. Each system includes a bar forming a bearing surface. Selector elements of the knitting machine are adapted to be tipped or pivoted about the bar as they pass the bar to move corresponding knitting needles into a knitting or non-knitting position. The bar extends in the direction of travel of the selector elements. A plurality of electromagnets are mounted at each selection station of the circular knitting machine. Each electromagnet has a pair of polar surfaces. The midpoint between all pairs of polar surfaces coincide with respect to each other and these coinciding midpoints are therefore equidistant from the bar forming the bearing surface.
