Cutting tool having parallel cutting blades

摘要

A tool having parallel cutting blades for cutting matching seam edges from two pieces of material, such as two pieces of carpet. The tool is comprised of an insulative housing having a pair of rotatable cutting blades disposed on opposite sides thereof in substantially parallel relationship; an adjustable guide mechanism disposed adjacent to each of the cutting blades for holding the material to be cut in proper alignment with the cutting blades; and a base member on which the housing is mounted. An electric motor is disposed inside the housing for rotating the cutting blades via a worm gear mechanism. The guide mechanism preferably includes a spring-mounted shaft, which is adjustable in a vertical direction to provide the proper spacing between upper and lower members of the guide mechanism, in accordance with the thickness of the material to be cut. The spring allows the shaft to move upwardly against the spring tension in the event an area of irregular thickness in the material is encountered to provide smooth continuous cuts in the material.
