Abstract
An automated means and method for cutting matte board and other soft materials. A matte board having a front display surface and spaced rear surface is placed on a planar support in facing contact with the display surface. After the matte is fixed into position, at least one cutting blade is caused to initially move simultaneously in both a vertical and horizontal direction to make a bevel cut from the rear surface through to the front surface. Once the cutting blade has passed through the front surface, the blade is caused to move horizontally so as to form a bevel cut along a predetermined length of the matte board.
Claims8
A machine for bevel cutting a planar work piece having a front face and back face, said machine comprising:
- a work surface for supporting said work piece,
- a cutting blade,
- a blade holder for holding said cutting blade at an angle with respect to said work piece back face,
- means for positioning and securing said work piece to said work surface so that said work piece can be quickly and easily positioned with respect to said cutting blade, said means for positioning and securing said work piece to said work surface comprising at least one power-activated clamping means contiguous with said work surface and at least one guide post mounted on said work surface and positioned to guide adjacent edges of a four-sided work piece,
- first means for moving said cutting blade into and out of said work piece at a first speed along said blade holder,
- guide means for constraining said blade holder to move in a direction parallel to the plane of said work piece,
- second means for moving said blade holder at a second speed along said guide means, and
- means for simultaneously operating said first and second moving means, the magnitude of said first speed being related to the magnitude of said second speed so that said cutting blade enters said work piece back face at an entry point, moves through said work piece at an angle to said work piece front face and exits said front face at a point displaced from said entry point in a direction parallel to said guide means.

A machine for bevel cutting a planar work piece having a front face and back face, said machine comprising:
- a work surface means for supporting said work piece in a stationary position with respect to said work surface;
- a cutting blade;
- a blade holder for holding said cutting blade at an angle with respect to said work piece back face, said blade holder comprising a bracket arm;
- a blade support bar;
- a blade extension post having a stop at a first end and passing through said bracket arm so as to be engaged in said blade support bar at a second end;
- a slide bearing engaged in a sliding relationship with said blade support bar;
- a shaft engaged with said blade support bar;
- and power means connected to said shaft whereby said shaft is caused to move said blade support bar along said bearing until said stop at said first end of said blade extension post engages said bracker arm;
- first means for moving said cutting blade into and out of said work piece at a first speed along said blade holder,
- guide means for constraining said blade holder to move in a direction parallel to the plane of said work piece,

- a worktable means for supporting said work piece in a stationary position with respect to said worktable,
- a cutting blade,
- a blade holder for holding said cutting blade at an angle with respect to said work piece back face,
- a first pneumatic cylinder for moving said cutting blade into and out of said work piece along said blade holder,
- first flow regulator means for controlling air pressure applied to said first cylinder so that said cylinder moves said cutting knife along said blade holder,
