Abstract
Apparatus and method for cutting a low density flexible material and passing through a semi-rigid base material simultaneously by means of a rotary milling cutter and simultaneously applying a compressive force to the flexible material to increase the rigidity of the flexible material while cutting the flexible material, the method includes passing the cutter through a part of the semi-rigid material. The compression force is applied by a partial cylindrical shaped compression head having the rotary milling cutter extending therethrough.
Claims19
A method of cutting a low-density flexible material having the characteristics of FIBERGLAS insulation having fibers comprising the steps of:
- supporting said flexible fiber material on a semi-rigid base;
- compressing said flexible fiber material to substantially a rigid state prior to cutting;
- and,
- cutting said compressed flexible fiber material with a rotary cutter that passes through said compressed flexible fiber material and at least a portion of said semi-rigid base simultaneously.
A machine for cutting sheets of low-density FIBERGLAS material;
- said machine having two laterally spaced tracks;
- said lateral tracks having end means supported on spaced longitudinal tracks;
- a partial spherical conversion head and a rotating milling cutter supported on said axis of said conversion head movably mounted on said lateral tracks and a first moving means connected to said conversion head;
- a second moving means connected to said lateral tracks to move said lateral tracks along said longitudinal tracks;
- and,
- said cutter being adapted to cut said low-density FIBERGLAS material when said cutter is moved relative to said low-density fiberglas material.
