ABSTRACT:
A cutter assembly for cutting sheets of relatively thin material is disclosed. The cutter assembly comprises a base member, a pair of support posts securely attached to the base member, and an elongated guide rail having a first end and a second end supported by the support posts in laterally spaced relation to the base member. A cutting strip is securely retained by the base member for receiving the sheets of material thereon. There is a cutter head slidably mounted on the elongated guide rail, and a cutting wheel operatively retained in rotatable relation by the cutter head. A spring biasing means biases the cutting wheel toward the cutting strip such that the cutting wheel is received in intimately contacting relation against the cutting strip. The cutting wheel moves along the elongated guide rail so as to intimately contact the cutting strip along the length thereof, so as to thereby permit cutting of the sheets of material when they are between the cutting wheel and the cutting strip. A spring member is disposed between upper and lower members of the base member so as to camber the upper member to match the bowing of the elongated guide rail that occurs as the cutting wheel moves along the elongated guide rail and therefore along cutting strip to cut the sheets of material.
