Abstract:
An envelope cutting system for cutting a material having a surface, the system comprising:a cutting unit including a frame having a lower support surface, a blade adjustment assembly coupled to the frame, and a blade assembly operatively connected to the frame, the blade assembly positioned at least partially within the frame such that a longitudinal axis of the blade assembly is substantially perpendicular to the lower support surface of the frame, the blade assembly including a blade retainer and a blade connected to the retainer, the retainer having a rigid collar, and the blade assembly and blade tip rotatable about the longitudinal axis, and a template having first and second substantially flat surfaces, a periphery and at least one edge defining at least one opening forming the shape of an unfolded envelope, the at least one edge including a chamfered surface running substantially between the first and second substantially flat surfaces, the lower support surface of the frame configured for contacting the first surface of the template and, the second surface of the template configured for placement upon the material to be cut, the rigid collar of the retainer configured to operatively engage at least one of the periphery and the edge of the opening of the template, thereby enabling the blade to cut a shape in the material which assimilates the shape of at least a portion of the at least one of the periphery and the edge.
