Abstract
A method for making a paper blank from a corresponding paper sheet includes: loading a paper sheet along a longitudinal orientation, resting on a supporting surface that defines a worktop; moving a carriage in parallel with the worktop; making a primary cut on the paper sheet along a cutting orientation perpendicular to the worktop, using a primary blade which slides relative to a primary anvil; making a secondary cut, sliding a secondary blade and a secondary anvil relative to each other at a secondary cutting unit. The primary cutting unit and the secondary cutting unit are actuated by an actuating assembly.

A method for making a paper blank from a corresponding paper sheet, comprising the following steps:
- providing:
- a frame,
- a carriage movable with respect to the frame between a first position and a second position, and
- a first cutting assembly and a second cutting assembly, each including a primary cutting unit and a secondary cutting unit, the primary cutting unit and the secondary cutting unit being connected to the carriage;
- loading a paper sheet along a longitudinal orientation, resting on a supporting surface that defines a worktop;
- while the carriage is in the first position, using each primary cutting unit to make a corresponding primary shear cut on the paper sheet, each primary cutting unit including a primary blade and a primary anvil sliding relative to one another along a cutting orientation perpendicular to the worktop, so to provide the corresponding primary shear cut;
- moving the carriage parallel to the worktop, from the first position to the second position;
- while the carriage is in the second position, using each secondary cutting unit to make a corresponding secondary shear cut, each secondary cutting unit including a secondary blade and a secondary anvil sliding relative to each other along the cutting orientation to provide the corresponding secondary shear cut,
- wherein each primary cutting unit and secondary cutting unit is actuated through an actuating assembly, and
- wherein each primary shear cut defines a corresponding primary cutting line and each secondary shear cut defines a corresponding secondary cutting line, each secondary cutting line being made on an associated primary cutting line.
A method for making a paper blank from a corresponding paper sheet, comprising the following steps:
- providing:
- a frame,
- a carriage movable with respect to the frame between a first position and a second position,
- a first cutting assembly and a second cutting assembly, each including a primary cutting unit and a secondary cutting unit, the primary cutting unit and the secondary cutting unit being connected to the carriage;
- loading a paper sheet along a longitudinal orientation, so that the paper sheet rests on a supporting surface that defines a worktop, the supporting surface being oriented horizontally, perpendicular to a vertical direction;
- with the carriage located at the first position, using each primary cutting unit to make a corresponding primary shear cut on the paper sheet, so that a primary notch is applied to the paper sheet by shear cutting;
- using a mechanical transmission system to move the carriage parallel to the worktop, from the first position to the second position;
- with the carriage located at the second position, using each secondary cutting unit to make a corresponding secondary shear cut, so that a secondary notch is applied to the paper sheet by shear cutting, and
- wherein each primary shear cut defines a corresponding primary cutting line and each secondary shear cut defines a corresponding secondary cutting line, each secondary cutting line being made on an associated primary cutting line.
