  • System for making cutouts and angular cuts in stepped siding
    Patent number: 3986418
    Abstract: A system for making cutouts and angular cuts in stepped siding uses a punch to remove, at the desired cut location, a rectangular section including the step and a small portion of both faces adjacent the step. The punch operates in a shearing manner with cutting surfaces progressively contacting the siding as the punch is moved into the die. Final cuts of the siding are made with cutters which do not require support of the stepped portion of the siding.
