¬ ESPECIFICATIONS
This perforating unit is designed to accept paper with or without line holes. The speed of the unit is controlled by a dancer. The paper then passes through the perforating section where the cross perforations and optionally vertical perforations are added. Each perforation is operated (thrown on or off) independently by reading an optical mark (OMR).
The dual position perforation section is fitted with cylinders sizing from 11” to 17”, enabling position 1 to produce perforations on one side and position 2 to produce perforations on the other side independently.

The horizontal perforating cylinders are either magnetic type for steel plates or conventional type accept perforating blades, which are mounted in quick change holders. Vertical perforations for continuous perforation are being done in a separate position on the input side of the unit and can be fitted with any amount of perf wheels; for selective vertical perfs we recommend to use magnetic plates. Each horizontal perforation is controlled separately by reading marks in on the edge of the paper in a free field, please see the drawing. |
