Abstract

A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs a transverse conversion function, a longitudinal conversion function, and an angled conversion function on the sheet material to create the packaging templates. The converting machine includes a tool head with a converting instrument. The orientation of the converting instrument is adjustable to enable performance of the angled conversion function and at least one of the longitudinal conversion function and the transverse conversion function.

First claim

What is claimed is:

1. A converting machine used to convert sheet material into packaging templates for assembly into boxes or other packaging, the converting machine comprising:
a converting assembly configured to perform a transverse conversion function, a longitudinal conversion function, and an angled conversion function on the sheet material as the sheet material moves through the converting machine in a feed direction, the transverse conversion function, the longitudinal conversion function, and the angled conversion function being selected from the group consisting of creasing, bending, folding, perforating, cutting, and scoring, to create the packaging templates, the converting assembly comprising:
a tool head selectively movable between opposing sides of the converting assembly, the tool head comprising a mounting block, a frame connected to the mounting block, and one or more converting instruments connected to the frame, the two or more converting instruments being configured to perform the angled conversion functions and at least one of the transverse conversion function or the longitudinal conversion function, an orientation of the two or more converting instruments being selectively adjustable about a first axis between a default orientation and an angled orientation, the default orientation being either parallel or perpendicular to the feed direction of the sheet material and the angled orientation being neither parallel nor perpendicular to the feed direction of the sheet material, the first axis being oriented in a first direction, and the mounting block being rotatable about a second axis, the second axis being oriented in a second direction that is different from the first direction, whereby the two or more converting instruments are movable about both the first and second axes.

2. The converting machine of claim 1 , wherein the two or more converting instruments are configured to perform the angled conversion function when the two or more converting instruments are in the angled orientation.

3. The converting machine of claim 1 , wherein the two or more converting instruments are configured to perform the transverse conversion function or the longitudinal conversion function when the two or more converting instruments are in the default orientation.

4. The converting machine of claim 1 , wherein the two or more converting instruments comprise a cutting tool and a creasing tool connected frame, such that adjustment about the first axis changes the orientation of both the cutting tool and the creasing tool.

5. The converting machine of claim 1 , wherein rotation of the mounting block about the second axis causes at least one of the two or more conversion tools to engage with or disengage from the sheet material.

6. The converting machine of claim 5 , wherein the two or more converting instruments comprise a cutting tool, and wherein rotation of the mounting block about the second axis is configured to cause the cutting tool to pass through the sheet material at an angle between opposing major surfaces of the sheet material.

7. The converting machine of claim 1 , further comprising a feed roller that is configured to advance the sheet material through the converting assembly.

8. The converting machine of claim 7 , further comprising a control system that is configured to control the operation of the feed roller and the tool head.

9. The converting machine of claim 8 , wherein the control system synchronizes a speed of the feed roller and movements of the tool head.

10. The converting machine of claim 1 , wherein the two or more converting instruments comprise a cutting wheel or a creasing wheel.

11. The converting machine of claim 1 , wherein, in the default orientation, the two or more converting instruments are generally parallel to the feed direction of the sheet material.

12. The converting machine of claim 1 , wherein, in the default orientation, the two or more converting instruments are generally perpendicular to the feed direction of the sheet material.

13. The converting machine of claim 1 , further comprising a carriage connected to the tool head and a track, the carriage being slidable along the track to move the tool head.

14. The converting machine of claim 1 , wherein the angled conversion function is formed diagonally across the sheet material.

15. The converting machine of claim 1 , wherein angled conversion function is formed at an angle through the sheet material.

16. The converting machine of claim 1 , wherein the angled conversion function comprises curved cuts or creases formed in the sheet material.

17. A converting machine used to convert sheet material into packaging templates for assembly into boxes or other packaging, the converting machine comprising:
a converting assembly configured to perform a transverse conversion function, a longitudinal conversion function, and an angled conversion function on the sheet material as the sheet material moves through the converting machine in a feed direction, the transverse conversion function, the longitudinal conversion function, and the angled conversion function being selected from the group consisting of creasing, bending, folding, perforating, cutting, and scoring, to create the packaging templates, the converting assembly comprising:
a first tool head selectively movable between opposing sides of the converting assembly, the tool head comprising a mounting block, a frame connected to the mounting block, and one or more converting instruments connected to the frame, the one or more converting instruments being configured to perform the angled conversion functions and at least one of the transverse conversion function or the longitudinal conversion function, an orientation of the one or more converting instruments being selectively adjustable about a first axis between a default orientation and an angled orientation, the default orientation being either parallel or perpendicular to the feed direction of the sheet material and the angled orientation is neither parallel nor perpendicular to the feed direction of the sheet material, the first axis being oriented in a first direction, and the mounting block being rotatable about a second axis, the second axis being oriented in a second direction that is different from the first direction; and
a second tool head comprising a mounting block, a frame connected to the mounting block, a cutting tool, and a creasing tool, both the cutting tool and the creasing tool being connected to the frame, the frame being movably connected to the mounting block such that movement of the frame about a first axis simultaneously changes an orientation of both the cutting tool and the creasing tool relative to the feed direction, the cutting tool and the creasing tool being configured to perform the angled conversion functions and at least one of the transverse conversion function or the longitudinal conversion function.

18. The converting machine of claim 17 , wherein an orientation of the cutting tool and the creasing tool is selectively adjustable between a default orientation and an angled orientation, wherein the default orientation of the cutting tool and the creasing tool of the second tool holder is either parallel or perpendicular to the feed direction of the sheet material and the angled orientation is neither parallel nor perpendicular to the feed direction of the sheet material.

19. The converting machine of claim 18 , wherein, in the default orientations, the one or more converting instruments of the long head are generally para
