ABSTRACT:
The cutting mechanism includes a cutter block mounting a knife blade arranged for movement along a slot in a cutting table. The cutter block is driven by a cable and a first drive pulley. The cable extends under and around the first drive pulley and a second pulley, with the first end of the cable fixed to a second end of the cutter block, and the second end of the cable fixed to a first end of the cutter block. The cable and the first and second pulleys are arranged such that when the cutter block lies between the first end of the slot in the table and a center of first drive pulley the first and second ends of the cable are drawn taut thereby stopping movement of the cutter block along the slot towards the first end, and such that when the cutter block lies between the second end of the slot in the table and a center of the second pulley the first and second ends of the cable are likewise drawn taut stopping movement of the cutter block along the slot towards the second end. The cutting mechanism also includes a slot and receptacle arranged to mount the knife blade on the cutter block such that the knife blade can easily be arranged within, and removed from the slot and the receptacle. The cutter block also includes a knife blade securing means positionable between a first position which secures the knife blade in the slot, and a second position allowing for removal of the knife blade. Notches are provided at the top end of the slot which allow for easy grasping of the knife blade when removing the knife blade from the slot and allow for easy insertion of the knife blade into the slot. The notches are sized such that the finger and thumb of a person can easily grasp the second end of the knife blade.
