PRIORITY: March 5, 1965 - UK

The invention relates to pattern systems for knitting machines and is only applicable to those knitting machines that use individually operable needles or any other

their suitable knitting organs, which are called "needles" for the sake of simplicity, and are equipped with means by which a selective and individual control can be exercised on these needles by means of separate feet which, depending on the particular sampling requirements, can either be left undisturbed, so that the corresponding needles can be actuated in a desired Yfelse, or can experience such an action ₃ that the respective needles either remain in the resting state or can alternate in action, depending on the type of patterned knitted fabric to be produced.

The term "assigned feet * is used here in general terms and is to be interpreted sufficiently broadly that this not only includes the more common case in which the feet on pushers, slides, voters or similar organs are provided separately from the needles, but also a case in which the feet are provided on the needles themselves

Although the invention mainly applies to Circular knitting machines with multiple feed, for example with a rotating needle cylinder, is determined, consists in this

Relationship is not limited as the invention can also be applied to other types of circular knitting machines, e.g. on machines for tubular goods and semi-tubular goods as well as in certain limited cases on flat stretching machines or Flaehkettelmaschinen, which can be operated with individually Needles are equipped.

For reasons of expediency and simplicity, it is assumed in the following (without, however, restricting the invention to this) that the feet associated with the needles are either left outside so that they are actuated by a cam or are to be pressed in so that the cam moves past in this way that the corresponding needles either knit or not knit.

So far , a knitting machine of the type mentioned has conventionally been equipped with a pattern device either of a completely mechanical or of an electromechanical type comprising rotatable drums provided with hooks in a certain arrangement, or rotatable baths equipped with "bits" or the like slides, Voters, star wheels, etc. are equipped. Such devices are mechanically complex and limited in their sampling area. In an effort to simplify these systems and expand their sampling options, it has already been

However, even in this case, these are the suggested ones Sample devices in their BG and limited in the yield of goods.

The object of the invention is to create a new type of Nustereyßfcems for knitting machines. That electronically controlled and not any of the aforementioned Limitations are subject to <=
