Abstract
A machine and a method to carry out workings on a sheet of a sufficiently rigid material is suitable to make containers. The machine includes a transverse working head guided by a first transverse guide member, one or more longitudinal working heads, each selectively positionable in a desired transverse position, guided by at least a second transverse guide member parallel to the first transverse guide member; and positioning mechanism configured to cooperate with each longitudinal working head in order to selectively position it in the desired transverse position.
Claims18
A machine to carry out workings on a sheet of a material suitable to make containers, comprising:
- a fixed frame that defines a support plane for said sheet;
- a feeder configured to feed said sheet in a first longitudinal direction along said support plane;
- at least a first transverse guide member disposed in a transverse direction, substantially perpendicular to said first longitudinal direction;
- a transverse working head, provided with a first cutting tool and/or a first creasing tool and guided by said first transverse guide member, to selectively carry out transverse cuttings and/or creasings on said sheet;
- one or more longitudinal working heads, each provided with a second cutting tool and/or a second creasing tool to selectively carry out longitudinal cuttings and/or creasings on said sheet, and each selectively positionable in a desired transverse position, guided by at least a second transverse guide member parallel to said first transverse guide member, to carry out longitudinal cuttings and/or creasings on said sheet;
- and
- a positioning mechanism, configured to cooperate with each of said longitudinal workings heads in order to position it selectively in said desired transverse position,
- wherein said positioning mechanism comprises a first transverse positioning device and a second transverse positioning device,
- wherein said first transverse positioning device is mounted on said transverse working head,
- wherein said second transverse positioning device is mounted on said fixed frame and movable in the transverse direction to be selectively engagable with any one of the longitudinal working heads,
- wherein each of said first transverse positioning device and said second transverse positioning device is configured to position each of said longitudinal working heads along said transverse direction, and
- wherein each of said longitudinal working heads is disposed between said first transverse guide member and said second transverse guide member and comprises sliding elements configured to cooperate slidingly with both said first transverse guide member and said second transverse guide member.
A method to make workings on a sheet of a material suitable to make containers, comprising the steps of:
- feeding said sheet in a first longitudinal direction;
- carrying out transverse cuts and/or creasings by means of a transverse working head, provided with a first cutting tool and/or a first creasing tool guided by first transverse guide member and mobile in a first transverse direction, substantially perpendicular to said first longitudinal direction;
- carrying out longitudinal cuts and/or creasings by means of longitudinal working heads, each provided with a second cutting tool and/or a second creasing tool and each selectively positionable in a desired position along said first transverse direction and guided by at least a second transverse guide member parallel to said first transverse guide member;
- selectively moving any one of the longitudinal working heads in said desired transverse position by moving a positioning device mounted on said fixed frame in the transverse direction and selectively engaging the positioning device with any one of the longitudinal heads even while said transverse working head is carrying out said transverse cuts and/or said transverse creasings,
- wherein each longitudinal working head is disposed between said first transverse guide member and said second transverse guide member.
