Procedure and Device for the Regulation of the drilling installations by Electric Spark drilling for paper strips or similar.

摘要

Device for regulating Plant Punch Paper Tape by means of Electric Spark. The Paper Tape (1), a perforated, Pass between two Chambers (14, 15) inside a Light Emitter, a Diaphragm (16) and (17), a Lens (22) and two photoelectric cells (23 and 24).The signal that reaches the Cells into a pre Amplifier (25) and then in another Amplifier, which passes to a driver Circuit that increases or decreases the power of the Electric Spark to the size of the perforations corresponding to the desired. There are different alternatives of realization. application in Drilling Grout of cigarette paper.
