ABSTRACT:
A disclosed embodiment of the invention is a belt-driven printer-cutter machine 10 including a roller-mounted feed/print machine section 14 and a fixed cutting machine section 16. A spline-type separable coupling 30-32 between these machine sections allows the feed/print section to be rolled on a fixed track 18 directly opposite the machine direction to separate the machine sections for maintenance, changing the printing plate 88 and cutting die 108, and to make other adjustments during machine setup. The sections may then be rolled back into engagement at the spline-type coupling to transmit power between the machine sections. The printer-cutter machine includes separate synchronous belts for the drive trains of each machine section. The machine may also include a separate synchronous belt for the fixed and adjustable rolls of each machine section. Specifically, the machine may include a dual auto-tensioned feed/print section belt 154, a fixed feed/print section belt 160, an auto-tensioned cutting section belt 230, and a fixed cutting section belt 244. Automatic belt take-up mechanisms 278, 282 driven by air cylinders 280, 284, automatically tension the synchronous belts 154, 230 driving the adjustable rolls of each machine section. This allows the nip between the upper and lower rolls of each machine section to be adjusted while maintaining constant machine speed and without affecting the proper registration between the machine sections and the leading edge of the paperboard blank.
