ABSTRACT:
A machine for sawing a plurality of spaced L-shaped slots through a stack of paper sheets starting from one edge surface of the stack, which slots are adapted to receive a device for binding the stack of sheets together. The machine includes a plurality of elongated saw blades having cutting teeth all around their peripheries and mounted side by side in spaced parallel relationship. The machine reciprocates the saw blades along their longitudinal axes to afford cutting engagement with the blades by the stack of sheets from any direction normal to the axes of the blades; while moving a planar support surface disposed normal to the axes of the saw blades and to which the stack of sheets is clamped in an L-shaped pattern to engage the stack of sheets with the saw blades and cut the L-shaped slots.
