Abstract

A shape cutting system for cutting a material having a surface. The shape cutting system includes a cutting unit and at least one template. The cutting unit includes a frame, a blade adjustment assembly and a blade assembly are coupled to the frame. The blade assembly is positioned at least partially within the frame such that a longitudinal axis of the blade assembly is substantially perpendicular to a lower support surface of the frame. The blade assembly includes a blade retainer and a blade connected to the retainer. A rigid collar of the retainer is configured to operatively engage at least one of a periphery and the edge of an opening of the template thereby enabling the blade to cut a shape in the cutting material which assimilates the shape of at least a portion of the at least one of the periphery and the edge.

Dependent claims

A shape 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 coupled 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 rotatable about the longitudinal axis;
and
at least one template having first and second substantially flat surfaces, a periphery and at least one edge defining at least one opening, the lower support surface of the frame configured for contacting at least one of the first surface of the template and the material to be cut, 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 cutting material which assimilates the shape of at least a portion of the at least one of the periphery and the edge.
