Abstract (en)
A cutting equipment (69) for two continuous paper forms (71, 72) in upper-lower relationship, comprising two dragging devices (97h, 971) for dragging the forms toward a common area of cutting (CA), a cutting device (98) operative on the area of cutting and an electronic control unit (109) for actuating the dragging devices and the cutting device in intermittent way. The equipment (69) further comprises two loop locating structures (103h, 1031) at different heights for delimiting two respective loops (Lph, Lpl) in the paper forms (71, 72), upstream from the dragging devices (97h, 97I) and two introduction devices (106h, 106I) engageable with the entering forms (71, 72) and actuatable for moving the entering forms toward the locating structures (103h, 1031). Two loop sensors (104h, 104I) supply loop signals associated, for instance, to a reference length (Lrh, Lrl) of the loops (Lph, LpI), while the electronic unity (109) controls the introduction devices (106h, 1061) in response to the signals from the loop sensors (104h, 1041) to reduce the variations of velocity of the entering forms (71, 72) jointly with the operation of the cutting device (98).
