Verfahren zum fortlaufenden Ablängen von Zuschnitten aus einem kontinuierlich bewegten Endlosmaterial und zugehörige Vorrichtung

摘要

A guideline is established for the speed of advance of the cutting unit (6) (a traveling bridge system) in the synchronous region. Before cut initiation, a control signal is developed, to adjust its speed finely in the region. To this end, spacing between the advancing previous cut line (13) and the cutting unit is measured for use as an actual value. Actual and desired values are compared, raising or lowering cutting unit speed (6) to achieve a match, upon which, cutting to length commences. An Independent claim is included for corresponding equipment. Its camera is mounted on the traveling bridge, held in an advanced location, corresponding to a cut length. Image data registered is evaluated in a controller, the output connected to the bridge drive system, to control its speed.
