Verfahren zum Ausloesen fliegender Trennwerkzeuge beim Ablaengen von rohraehnlichen Teilen

The proposal relates to a process for triggering flying cutting tools for the cutting of tubular parts such as rods, pipes, etc. Having a structured surface in the continuous manufacturing process, whereby the parts, after leaving the shaping tools and the tempering section, are cut by flying cutting tools, and the triggering of the synchronous and cutting movement of the cutting tools takes place according to specific features. The process is characterized by the fact that the feature for triggering the synchronous and the cutting movement of the cutting tools is the recognition and detection of the contour of the part (1) to be cut after leaving the tempering section, whereby the recognition and detection of the contour is performed by an arrangement of two sensors (3) linked by logic operations, and the synchronous and cutting movement of the cutting tools is triggered by a single output signal from this sensor arrangement (3).
