* Very rarely there is film which can not be image processed.
Also, control is not possible if there is a printed pattern over a transparent film seal and the image contrast is not clear.
The double cut system described below eliminates burrs on the in-line corner cut unit. It is a measure against product liability and significantly improves the value of the merchandise.
A high precision CCD camera directly over the cutter observes the shape of the corner cut and the image is analyzed by computer. (It handles corner cuts of any shape.) Even if the location of the corner cut punched hole is altered by a change in printing pitch, the software controls the shear cutter so the cut is in the center of the punched hole (for single cut). An AC servo motor drives the

Single cut enables notching to be positioned just inside of cutting, thus tearing during transportation and injury by the notch edge is avoided.
Double cut enables previously impossible single side notching.
