Guillotine Cutter.
The paper to be cut is placed on the table F, touching the back gauge G, which can be brought backwards or forwards by means of the handle H, thus regulating the size of sheet.
The machine is set in motion by means of the lever A, which acts upon a friction-clutch connected with the driving-gear. This causes the knife-bar B and the clamp C to descend. {175} When the latter meets the paper its progress is arrested. The knife D, however, continues to descend, and passes through the sheets of paper. By means of slots placed at the back, the knife is made to take a diagonal course. The pressure of the clamp is maintained upon the paper during the cutting operation by means of a powerful spring contained in the tube E.
