Abstract

A cutting apparatus for cutting blank profiles comprises a first cutting device located at a first position in the apparatus, a second cutting device located at a second position, the second position being separated from the first position along a first axis of the apparatus, and a third cutting device located at a third position, the third position being separated from the first position along a second axis and along a third axis of the apparatus. A chariot moves along the third axis while a support adapted to hold a blank profile is mounted to the chariot and moves along the first and second axes of the apparatus. A greater number of cutting devices may be used. Cutting devices may be arranged in rows along the third axis.

Claims

1. A cutting apparatus for cutting blank profiles, comprising:

the first plurality of cutting devices forming a first row disposed along the third axis;

the second plurality of cutting devices forming a second row disposed along the third axis and separated from the first plurality of cutting devices along the first axis;

the third plurality of cutting devices forming a third row disposed along the third axis and separated from the first and second pluralities of cutting devices along the second axis;

a chariot configured to move along the third axis of the cutting apparatus; and

a support mounted to the chariot, the support being configured to hold a blank profile and to move along the first axis and along the second axis of the cutting apparatus.

10. The cutting apparatus of claim 1, wherein:

the chariot is further configured to move along the second axis of the cutting apparatus; and

the support is configured to move along the first axis in relation to the chariot.

11. The cutting apparatus of claim 10, comprising:

a first servo motor adapted to move the support along the first axis of the cutting apparatus;

a second servo motor adapted to move the chariot along the second axis of the apparatus; and

a third servo motor adapted to move the chariot along the third axis of the cutting apparatus.

12. The cutting apparatus of claim 10, comprising:

a second chariot configured to move along the second axis and the third axis; and

a second support mounted to the second chariot and configured to move along the first axis in relation to the second chariot.

14. The cutting apparatus of claim 1, comprising:

a central sub-frame containing the chariot; and

a first outer sub-frame and a second outer sub-frame on opposite sides of the central sub-frame and separated along the first axis;

wherein one of the first and second outer sub-frames contains the first and third cutting devices; and

wherein the other one of the first and second outer sub-frames contains the third cutting device.

15. The cutting apparatus of claim 14, wherein:

the first and outer sub-frames are detachable and separable from the central sub-frame; and

each of the first and second outer sub-frames includes a pair of opposite faces, one of the opposite faces including a first set of cutting devices and the other one of the opposite faces including a second set of cutting devices, the first and second sets of cutting devices being positioned so that a rotation by 180 degrees of the outer sub-frames about the second axis and attachment of the outer-frame to the central sub-frame brings one of the first and second sets of cutting devices in a position for cutting the blank profiles.
