Abstract
The rotary cutting blade is mounted on a cutting machine which dispenses and cuts sheet material. The cutting machine includes a frame for supporting a cutting table top and a dispenser for supporting a roll of floor covering material. The rotary disk shaped cutting blade is mounted on a support block the frame below the table top for movement along a slot in the cutting table. A cable or chain driven rotary drive drives the block back and forth and at the same time provides the rotary motion to the cutting disk in a direction such that a leading edge of the disk moves upwardly relative to the floor covering material as it cuts. The chain passes over a sprocket on the block which carries a clutch so that the clutch slips when the block reaches one end of the slot and allows the chain to continue driving the rotary blade. A rotary sharpening disk is mounted at one end of the slot and is driven by the chain so as to rotate against the blade in a sharpening action while the block remains stationary.
