Abstract (en)
[origin: EP0620088A1] The device (4) for cutting semi-rigid sheets (21), particularly of corrugated cardboard, one by one, comprises a cutting tool (16) fixed onto a tool holder plate (10), a pressing cylinder (9) capable of receiving, as bearing surface, a covering made of steel of thickness d1 or a covering made of a resilient material of thickness d2, a first electronically-controlled independent motor (11) with two directions of rotation, driving the tool holder plate (10) in its reciprocating motion, and a second motor driving means (8) for feeding the sheet, means (23) for monitoring the rotation of the pressing cylinder (9), means for displacing the pressing cylinder heightwise and an electronic control circuit (24) equipped with means (25) for inputting operating parameters among which at least the value of the thickness (d1, d2). The electronic circuit (24) is programmed so that it controls the means (30) for displacing the pressing cylinder (9) heightwise depending on the value of the thickness parameter and so that it controls the first and second motors so that the linear speed of the feed means (8) and that of the tool holder plate (10) are equal to the peripheral linear speed of the pressing cylinder (9) at the moment when the cutting tool (16) offers up the sheet (21) under the pressing cylinder (9), and so that the linear speed of the tool holder plate (10) is equal to the peripheral linear speed of the pressing cylinder (9) for as long as the cutting tool (16) is in contact with the said pressing cylinder (9). <IMAGE>
