Abstract
A machine for cutting insulation material into semi-circular blocks. Circular cutting blades are mounted reciprocally on a support shaft. A router functions to cut a groove in the insulation material to provide clearance for the cutting blade support shaft.
Claims8
A circular insulation saw apparatus for cutting blocks of insulation material into pipe insulation members comprising:
- a. a frame with a material feed surface having first and second end portions and being supported by the frame, there being further provided a saw mount opening in the feed surface;
- b. a powered, cylindrical cutting blade movably mounted with respect to the feed surface at the opening;
- c. shaft means spanning the saw mount opening for at least partially providing support for the cutting blade;
- d. a blade carriage positioned near the opening comprising at least one radial strut extending from the shaft to the cutting blade, and the adjustable means comprises a blade support slideable along the radial strut;
- and
- e. adjustable means carried by the blade carriage for supporting the cutting blade in the opening so that the center of the circular blade substantially coincides with the planar surface, the adjustable means being movably supported to slide upon the carriage into a plurality of positions so that the carriage and adjustable means can accommodate cutting blades of varying diameters.
