Abstract
An apparatus for slitting a web moving along a path comprises a mounting block adapted to be fixed at a location adjacent to the web path. A guard assembly includes a guard plate secured to rod members projecting from the mounting block. A blade guide is mounted on and shiftable along the rod members, and at least one blade is carried by the blade guide. An actuator serves to shift the blade guide along the rod members between an extended position at which the blade projects in a slitting position beyond the guard plate and into the web path, and a retracted position at which the blade is withdrawn from its slitting position and from the web path to a position where it is shielded from exposure by the guard plate.

Apparatus for slitting a web moving along a path, said apparatus comprising:
- a mounting block adapted to be fixed at a location adjacent to said path;
- a guard assembly comprising a guard plate secured to rod members projecting from said mounting block;
- a blade guide mounted on and shiftable along said rod members;
- at least one blade carried by said blade guide;
- and
- actuating means for shifting said blade guide along said rod members between an extended position at which said blade projects in a slitting position beyond said guard plate and into said path, an intermediate position at which said blade remains extended beyond said guard plate yet is withdrawn from the path wherein both the blade guide and the guard plate move together with respect to the mounting block, and a retracted position at which said blade is withdrawn from said intermediate position and from said path and is shielded from exposure by said guard plate wherein the blade guide moves with respect to the guard plate.

- a guard plate secured to rod members projecting from the mounting block;
- a blade guide mounted on and shiftable along the rod members;
- at least one blade carried by the blade guide;
- and
- actuating means for shifting the blade guide along the rod members between an extended stage in which the at least one blade projects in a slitting position beyond the guard plate and into the path,
- an intermediate stage in which both the blade guide and the guard plate move together with respect to the mounting block and in which the blade remains extended beyond the guard plate yet is withdrawn from the path, and
- a retracted stage in which the blade guide and the at least one blade move with respect to the guard plate and the mounting block, and in which the blade guide is withdrawn from the intermediate stage and from the path and is shielded from exposure by the guard plate.
