Abstract: This disclosure relates to a winding machine which has a plurality of equi-rotating rolls, at least two guide elements arranged mirror-wise, between which the sheets to be rolled up pass, with arched distal portions arranged in a mirror-like manner, the two guide elements being connected to a support configured to position in a mutually exclusive manner only one guide element at a time in the rolling space defined between the winding rollers. Moreover, the winding machine is equipped with a motor unit controlled so as to rotate the winding rollers in a direction or in the opposite direction depending on which of the two guide elements has its respective distal portion facing the rolling space.

Abstract: Abstract: The present disclosure provides an automatic cutting device for printed supports which allows to compensate for the space created between the sliding planes, so as to always sustain the support to be cut and allow it to pass from one sliding plane to another and reach the relative unloading rollers avoiding jam at the device outlet. This result is achieved by means of an array of fins supported at the second sliding plane, configured to move from a closed configuration, in which all the fins protrude from the second sliding plane towards the first sliding plane and occupy the transverse cutting zone, to an open configuration in which they leave the transverse cutting area free so as to allow undisturbed movement of the cutting unit. This array of fins in closed configuration sustains the printed support cut in the passage from the first sliding plane to the second sliding plane.

Abstract: The present disclosure provides a process for manufacturing a printed support (S), which can be cut by any automatic cutter capable of reading an optical code (OC), which does not require updating the resident software of the microprocessor unit that controls the printer (or printers). A printing system of a printable support which implements the process is also disclosed.

Abstract: The invention relates to a method for cutting substrates with printed images in an automatic cutting device. The longitudinal cutting marks (LM) are provided with a discontinuity (N) arranged upstream of each transverse cutting mark (TM) with respect to a feeding direction (F) of a substrate (S) and spaced therefrom by a predefined known measure (d). The automatic cutting device has a first optical unit configured to detect the transverse cutting marks (TM) and a second optical unit configured to detect the discontinuities (N) in the longitudinal cutting mark (LM). Since the velocity of the substrate is known, the control system activates the first optical unit when the transverse cutting mark (TM) actually passed underneath it.

Each cutting unit has a pair of parallel blades spaced apart at a distance corresponding to a width of the edges, a backing plane arranged underneath the supporting plane of the cutter, and a connecting arm which extends from a frame of the cutting unit to the backing plane. The connecting arm is parallel to the blades and is arranged between them and a through opening is formed in a portion of the backing plane under the connecting arm.

Abstract: A device is provided for cutting paper and other graphic substrates (10) in roll on two perpendicular axes simultaneously with automatic errors correction, both in the feeding with respect to a direction (F) along the longitudinal axis (Y) of the substrate, and of the deviation of the image with respect to the edge of the substrate itself. For this purpose, a motor (5) is provided at the horizontal cutting unit (4), in addition to a drive motor (6), suitable for shifting the cutting path in order to make it coincide with the correct cutting line (Tx). In the same way, for the longitudinal cutting assembly (14) along the (Y) axis, in addition to a motor (7) for performing the cut, a motor (8) is provided suitable for translating along the (X) axis the whole cutting assembly on the basis of lateral deviations detected by means of an optic cell (9), whose signals are processed by a microprocessor for the drive of the motor (8).

Abstract: A device for trimming and automatically cutting of either multiple or single images, the images produced for example through digital rendering on paper and other graphic and photographic substrates, wound in reel or being in single sheets (10), especially of large size. Problems in using known devices of this type with feeding rollers (2) with a length corresponding to the substrate width have the consequence of a slowing down of the production owing to the excessive care necessary when introducing at the same time parallel sheets of large size. These problems can be overcome by using rollers of reduced length, but only by adding errors in the forward movement of the substrate, errors which are remedied by of optical sensors (4, 4?) for detecting the separation mark (M) between the images (10a, 10b, . . . ) as well as its angle with respect to the cutting line (7), and by a pair of length differential measuring devices (6).
