ABSTRACT:
Apparatus for severing sheet material by a cutter device that is mounted upon a rail assembly for reciprocating movement. The rail assembly includes a channel member with an outwardly extending guide rail. A separate cutter bar is supported on the guide rail and extends longitudinally above the guide rail. A carriage is mounted on the guide rail for reciprocating movement and includes dual rollers which engage opposite sides of the cutter bar. The carriage is held against the guide rail by a pressure roller which engages the inner side of the guide rail. The pressure roller includes an adjustable mounting arrangement for adjusting the force that clamps the carriage against the guide rail. One of the dual rollers has a dull edge which engages the cutter bar while the other dual roller has a sharp edge to sever the paper or other sheet material as the carriage moves longitudinally of the cutter bar.
