ABSTRACT:
The invention relates to a device on a knitting machine equipped with slider needles for controlling the laying in of a thread (28) into the open needle hooks (5.2). In order to avoid that the thread is not laid into the hooks correctly or that a thread which has already been laid into the hook, jumps out of the hook (5.2) during the closing movement of the slider parts (6) on account of vibrations or the like, the slider parts (6) of the slider needles are provided with inclined faces (6.5) which project when the hooks (5.2) are closed into the thread spaces (32) formed by these hooks and the needle and slider parts (5,6). In this way the thread portions between the thread guide (29) and the slider needles are pressed deeply into the thread spaces (32) during the closing movement of the slider parts (6), so that the thread sections laid into the following slider needles with hooks still open come securely into the respective thread spaces (32) or are retained therein FIG. 3).
