Method for Cutting Out Coating Plates for Use in Digital Printing Units

Abstract

Method for cutting out coating plates for use in digital printing units. A method for cutting out coating plates for use in digital printing units, where the cutting of coating plates is effected by means of a digital cutting machine, the cutting machine including a computer control and further including a mother roller, the method including at least the following steps: a file including at least cutting data is transferred to the computer control of the digital cutting machine; a sleeve with coating plate material is mounted on the mother roller of the cutting machine; the coating plate mounted on the sleeve and the mother roller are cut out in the ratio 1:1 whereby is achieved, among others, that a mounting machine is no longer necessary in order to apply coating material on a sleeve, whereby registering accuracy is increased and shrinking effect is avoided.

Claims

A method for cutting out coating plates for use in digital printing units, where the cutting of coating plates is effected by means of a digital cutting machine, the cutting machine including a computer control and further including a mother roller, wherein the method includes at least the following steps: a file at least comprising cutting data is transferred to the computer control of the digital cutting machine; tape is fitted on a sleeve; the coating plate material is mounted on the sleeve; the sleeve with coating plate material is mounted on the mother roller of the cutting machine; the coating plate mounted on the sleeve and the mother roller is cut out in the ratio 1:1.

2. (canceled)

3. A digital cutting machine for cutting out coating plates, the cutting machine being computer controlled, wherein the cutting machine at least includes a mother roller for sleeves that tape is fitted on the sleeve and that the coating plate material is mounted on the sleeve.

4. A digital cutting machine for cutting out coating plates according to claim 3, wherein the cutting machine comprises a first side, a second side, a third side, a fourth side and a top, the first side including a tape cylinder and a sleeve cylinder, and that the second side includes the mother roller.

5. A digital cutting machine for coating plates according to claim 3, wherein the third side of the cutting machine includes a plate storage compartment.

6. A digital cutting machine for coating plates according to claim 3, wherein the cutting machine further includes at least one cutter beam and at least one cutter head, and that the cutting machine further includes means for moving the cutting machine.

7. A digital cutting machine for coating plates according to claim 3, wherein the cutting machine is movable at least along a first axis and a second axis, where the first axis is parallel with the mother roller and substantially horizontal, and where the second axis is perpendicular to the first axis and substantially vertical.

8. A digital cutting machine for coating plates according to claim 3, wherein at least one cutter beam is disposed in the direction of the first axis, and that the at least one cutter head is disposed in the direction of the second axis and is movable in the direction of the first axis along the cutter beam as well as in the direction of the second axis towards/away from the mother roller.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0074] FIG. 1 shows a digital cutting machine 1 for cutting coating plates in perspective view, where the cutting machine 1 is equipped with a computer 2 located in the cutting machine 1, and in the shown example provided with a display 3 with a keyboard 4 and a mouse 5 for use in operating the computer 2 and thereby the cutting machine 1. The cutting machine 1 also includes a mother roller 7 for sleeves.

[0075] The Figure also shows that the cutting machine 1 has a first side 8, a second side 9, a third side 10, a fourth side 11 and a top 12, the first side 8 including a tape cylinder 13 and a sleeve cylinder 14, and wherein the second side includes the mother roller 7, whereas the third side 10 includes a plate storage compartment 15.

[0076] On the Figure is also seen a manual pressing roller 6 for use in mounting plate material, whereby the pressing roller 6 is moved to the sleeve cylinder 14, having the purpose of ensuring that the plate material 25 is correctly placed on the sleeve 23.

[0077] The cutting machine 1 has a cutter beam 16 and a cutter head 17, and the cutting machine 1 furthermore has moving means 18 for moving i.a. cutter beam 16, cutter head 17 and mother roller 7 of the cutting machine.

[0078] In order to understand the moving pattern of the cutting machine, two axes are drawn on the Figure, a first axis 19, a second axis 20 and a direction of rotation 21, all of which being described in more detail in the following.

[0079] The cutting machine 1 is at least movable along the first axis 19 and the second axis 20, wherein the first axis 19 is parallel with the mother roller 7 and substantially horizontal, wherein the second axis 20 is perpendicular to the first axis 19 and substantially vertical.

[0080] As it appears on the Figure, the cutter beam 16 is disposed in direction of the first axis 19, whereas the cutter head 17 is disposed in direction of the second axis 20, wherein the cutter head 17 is movable both in direction of the first axis 19 and along as well as in parallel with the mother roller 7 and in direction of the second axis 20 down against or up from the mother roller 7.

[0081] The direction of rotation 21 indicates the directions of rotation of mother roller 7, tape cylinder 13 and sleeve cylinder 14, which are all substantially parallel.

[0082] FIG. 2 shows an example of a sleeve 23 wherein the sleeve 24 is cut out and stripped and ready for entering into production, wherein the plate 24 now has the shape that enables precise application of coating on a print, without coating being applied on anything else than the print and only on the parts of the print on which coating is desired, and therefore not on parts of the print that possibly are to be glued together.
