Abstract: A device for changing threads in circular knitting machines, the device having several thread-changing units each of which is assigned to a knitting system of the circular knitting machine. The units have several thread-changing fingers for guiding various threads which can be selectively led to a knitting zone. The thread-changing units have members which include devices for cutting and clamping threads. In accordance with the invention, the thread-changing member of each thread-changing unit is connected with an electrically operated preselector, and is mechanically operated in dependence upon this preselector.

Abstract: Method and apparatus for processing the information content of a pattern drawing in coded form for application to an utilization facility such as a storage device for controlling textile machines. The pattern drawing is scanned line-by-line and point-by-point and the scanned points are projected in enlarged form so that the information content of the scanned points is comprehended by an operator who registers its, by pressing a corresponding information key, first of all in an intermediate storage device of limited capacity, the content of whose stages is made visible in corresponding adjacent fields in an optical indication device. The information of the intermediate storage device is transferred in groups to the storage device as soon as the intermediate storage is filled up.
