ABSTRACT:
This invention relates to a novel apparatus for cutting mats of compressible insulation materials arranged in stacks into small intricately shaped pieces which comprises an elevatable platform which raises the stack and compresses same against the undersurface of a rigid pattern supported in spaced relation beneath an overhead framework on uprights which are rotatable and include an offset portion sized and positioned to receive that part of the fabric cutter overhanging the axis of upright rotation regardless of the position of the cutter adjacent the edge of the pattern. The invention also encompasses the novel method of cutting stacks of compressible sheet insulating materials which comprises the steps of elevating the stack into compressed relation beneath one or more patterns supported on rigid rotatable uprights having offset portions, cutting around each pattern with a fabric cutter while rotating the upright supporting same so that the offset therein accommodates that portion of said cutter overhanging the axis of the upright of rotation to free the shaped pieces from the stack, and releasing the stack thus cut.
