Abstract: A machine for cutting out flat material comprising a support for the flat material, a carriage guided for displacement along the support by at least one guide rail, the carriage bearing a beam extending above the support and pivotable, in relation to the carriage, about an at least approximately vertical, first pivot axis, this beam having at least two arms interconnected by a joint having a second pivot axis parallel to the first pivot axis and the outer arm of said two arms bearing a cutting mechanism pivotable, in relation to the outer beam arm, about a third pivot axis parallel to the first pivot axis and a foot of the cutting mechanism being in contact with the support during operation. In order to simplify the construction of the beam but still ensure that the cutting mechanism always rests perpendicularly on the support, this cutting mechanism is adapted to swivel, in relation to the support, about a tilt axis parallel to the support and rests with its foot on this support.

Abstract: A precision saw is the subject of the present invention. A framework mounts a planar member and presents a work surface having an opening for receiving a saw blade. A C-member is coupled with the framework and has upper and lower arms extending parallel to and above and below the work surface. The planar member is mounted for pivotal movement by a pivot rod positioned at a point in a horizontal plane located substantially at the center of the bight of the member. A saw blade extends between the upper and lower arms for cutting a work piece and a drive system is provided for moving the C-member in a generally vertical plane about the single pivot point.
