Extrusion plant operating method in which the operating speeds of the various drive units are synchronized by use of a common synchronization factor that is changed to change the speeds of the all drives by an appropriate amount

摘要

Method for operating an extrusion plant that has synchronized drive units with the set value for the operating speed of a drive unit equal to the product of its maximum drive speed, a unit dependent normalized ratio value and normalized synchronization factor that is the same for all drive unit. The ratio value relates the relative speeds of the individual drive units in a fixed manner. Changing of the synchronization factor results in synchronous speed changes. An independent claim is made for an extrusion plant with a number of drive units and a programmable control and operating unit.
