Abstract
A machine for folding sheets receives a stream of sheets. A first folding unit is followed by a further unit. The first folding unit has at least one buckle plate and at least two folding rollers to fold the sheets. A monitoring device checks the stream for defects. A control unit activates a removal device for removing waste products when a defect is detected. The monitoring device is disposed at the entry region of the buckle plate and monitors the stream in the buckle plate. The removal device is disposed downstream of the first folding unit and upstream of the further unit. The system, which is suitable for industrial folding machines, reliably detects unusable waste products in the folding process even before production might be affected.
