A cutting equipment for continuous paper strips having images arranged in sequence along multiple rows comprising a longitudinal cutting mechanism for separating the rows from the strips and a transversal cutting mechanism for separating image sheets from the rows and in which the image sheets have different longitudinal dimensions and possibility of random variations between row and row, The equipment further comprises individual feeding mechanisms for feeding, in an independent way, the rows with respect to the transversal cutting mechanism; a buffer device, of compensation for the different feeds of the rows, and an electronic control unit for actuating the feeding mechanisms and the transversal cutting mechanism so as to present the trailing edges of said image sheets in alignment for a simultaneous cutting by the transversal cutting mechanism and extracting one or more images from the cutting mechanism, after its actuation, as preparation of collecting.

Cutting equipment and method for continuous paper strips with images arranged along multiple rows

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