Abstract

Bei der Strickmaschine mit einer Fadenwechseleinrichtung mit Knotvorrichtung, in welcher ein Faden von der Knotvor­ richtung (10) über eine Fadenspeichervorrichtung (30) zu einer Fadenverarbeitungsstelle (16) geführt wird, ist die Fadenlänge zwischen der Knotvorrichtung und der Fadenver­ arbeitungsstelle immer gleich gehalten, so daß der Steuer­ einrichtung (20) zur Auslösung einer Knotenbildung beim Fadenwechsel feste Daten für diese Länge vorliegen. Außer­ dem wird die Antriebsbewegung der Strickmaschine (17) mittels eines Weggebers (22) überwacht, der unabhängig von der Nadelteilung eines Nadelbettes pro Weglängeneinheit eine vorgegebene Impulszahl liefert, die als Taktimpulse in der Steuereinrichtung (20) ausgewertet werden. Durch diese Maßnahmen läßt sich der Aufbau der Steuereinrichtung vereinfachen. In the knitting machine with a thread changing device with knotting device in which a thread from the knot in front direction (10) via a thread storage device (30) a thread processing point (16) is the Thread length between the knotting device and the thread ver Work place always kept the same, so that the tax device (20) for triggering a knot formation in the Thread changes have fixed data for this length. Except the drive movement of the knitting machine (17) monitored by means of a displacement sensor (22) which is independent of the needle pitch of a needle bed per path length unit provides a predetermined number of pulses, which as clock pulses be evaluated in the control device (20). By these measures can be the structure of the control device simplify.
