instead of the pin drum of the long-known mechanically operating pattern devices assigned to each user selection point of the machine stationary electromagnetic actuators are provided which, if necessary, are electrically controlled. Included multi-system dog knitting machines in the meleten cases Each knitting stone is assigned an election point separate electromagnetic actuators are assigned to each knitting system for the electrical pattern devices mentioned, so that a large number of such electromagnetic actuators is required. This one The disadvantage, however, is offset by the advantage that it is associated with such electrical coughing devices with an adapted Iuater program carrier sample reports can be produced with practically unlimited cough width.

The invention is based on the still widespread multi-system dog knitting machines with purely mechanical pattern devices, which have a pin drum at each pattern selection point, which at the same time has a pattern program carrier and a switching element form. With these purely mechanically working sample facilities, a sample change is very time consuming, because when changing a pattern on the machine, all pin drums of the machine have to be provided with a new pin arrangement. The invention lies in the special task is based on eliminating this disadvantage and creating a sample device for a multi-system round

knitting machine to create in which all pin drums can be omitted and replaced by an equivalent electrical sample device, which is not a larger one Makes manufacturing effort required and at which above all a pattern change can be carried out very quickly.

The task is solved according to the invention by that the pattern device only has a single Sate of electromagnetic Has actuators, which in a all stationary and each forming a Selektierapparat Sample slide sets shared preselection device synchronized with the nadol carriers and with all of the selection devices influencing common control member rotates. The common pre-selection device shows the pattern slide oines individual selection apparatus according to the number and mutual arrangement corresponding preselector slides, which Powells can be switched into one of two stable ones via an adjusting slide using an assigned reversing solenoid End cleats are adjustable.

In place of the numerous pen drums that came with

Pattern swings in time-consuming work new with pens must be occupied, so occurs in the inventively designed pattern device a single circumferential Set of electromagnetic cleats, their number of number of different levels of the cough feet of the sample plates of the Ha = - aahine and thus, as with the known mechanical

The electric one The program carrier is known per se or already proposed designed so that sloh

Γ with him a cough from one in a very short time can accomplish feasible replacement of one of its parts. For this purpose, pattern program carriers in the form of pinboards are particularly suitable, in which a desired pattern can be checked with the eye by means of a Can store plug. In this case, these plugs can be held in a joint holding »in the manner already proposed. Foil attached to the pegboard, pressed in together and later removed again together Be pulled out. As a cough program carrier but can serve caretaker cards or ttuster cartridges, which only have to be exchanged when changing coughs

According to the invention, each selection apparatus of the pattern device has a common latch which influences all of its pattern slides, and the latches of all selection apparatuses are controlled by means of the control member rotating together with the needle carriers and the preselection apparatus adjustable. This control element can be designed as a cam

A pattern device according to the invention thus forms an equivalent replacement for the pin drums of the known mechanical pattern devices with the gate part, that with her pattern changes can be carried out very quickly. The sample device according to the invention can be produced very inexpensively »

Details about the invention emerge from the following description in connection with the drawing, on which an embodiment of a sample device according to the invention is shown more or less echenatically.
