The central challenge to the bag making machine is the processing of different substrates from reels. In the production process, this can result in a large dynamic infeed error after unwinding and difficult scanning of the guide criterion in stop & go operation.
Erhardt+Leimer can offer convincing solutions for this area. Thus, our winding station control stands out through its high control dynamics, even at high production speeds.
The synchronizable color line sensor reliably detects not just the lateral deviations of the guiding criterion, but, with the appropriate attachment, also detects deviations in the longitudinal register during stop & go operation.
