摘要： An equipment (111) for high speed transversal perforations of variable lengths on continuous forms (32) in movement comprising a blade support (34) with at least a perforating blade (39a) and a blade contrast (112) having at least one projecting profile (41a) of contrast for the perforating blade (39a) and blade and contrast servomechanisms (43, 128) for rotating the support blade and the blade contrast to carry the perforating blade against the projecting profile in synchronism with the form. The blade contrast (112) comprises a hollow cylinder (113) of low rotational inertia, defining the projecting profile (41a) as sectors with axial extensions different in dependence on their angular positions. The contrast servomechanism (128) is settable for selecting an angular phase of the hollow cylinder (113), such to positioning, for the contrast with the blade, a sector of the projecting profile (41a) having axial extension equal to the requested length of the perforation (P) and in which the hollow cylinder (113) is rotatable around a support shaft (114), without any mechanical contact, as a radial air bearing of pneumostatic type.

摘要： Perforating equipment (111) for high speed transversal perforations of variable lengths on a continuous form (32) in movement is disclosed. The perforations are carried out by means of a perforating blade (39a) against a projecting profile (41a) of a blade contrast (39a) and blade and contrast servomechanisms (43, 128) for rotating a support for the blade and the blade contrast. The projecting profile (41a) has sectors with axial extensions different in dependence on their angular positions. The contrast servomechanism (128) is settable for selecting an angular phase of the blade contrast (39a), such to positioning, for the contrast with the blade, a sector of the projecting profile (41a) having axial extension equal to the requested length of the perforation (P). The blade contrast can be constituted by a hollow cylinder (113) rotatable around a support shaft (114) as a radial air bearing of pneumostatic type.
