Method and apparatus for adjusting and maintaining a position of a cutting surface of a perforating apparatus

A method for perforating a substrate, the method comprising:

• providing a frame;
• a housing rotatably supported by the frame, the housing adapted to rotate about a first axis;
• and a support member comprising a first end portion and an opposing second end portion, the first end portion rotatably supported by the housing, the support member adapted to rotate about a second axis, the second axis being offset from the first axis, the support member comprising a first cutting surface;
• providing a roll positioned adjacent the support member, the roll adapted rotate about a third axis, the roll comprising a second cutting surface adapted to intermittently contact the first cutting surface as the roll rotates about the third axis;
• providing a holding device selectively operable in a first configuration and a second configuration, the first configuration permitting rotation of the housing about the first axis and the second configuration preventing rotation of the housing about the first axis;
• placing the holding device in the first configuration and selectively moving the first cutting surface toward or away from the roll by rotating the housing about the first axis;
• placing the holding device in the second configuration;
• rotating the roll and second cutting surface about the third axis;
• advancing a substrate between the first cutting surface and the rotating roll with the holding device in the second configuration;
• and
• perforating the substrate to form a line of weakness.

A cutting apparatus comprising:

• a frame;
• a housing rotatably supported by the frame, the housing adapted to rotate about a first axis;
• a support member rotatably supported by the housing, the support member adapted to rotate about a second axis, the second axis being offset from the first axis, the support member comprising a cutting surface comprising a distal edge;
• a clamp connected with the frame, the clamp selectively operable in a first configuration and a second configuration;
• wherein in the first configuration, the clamp is disengaged from the housing such that the distal edge of the cutting surface is selectively movable toward or away from the first axis by rotating the housing about the first axis;
• and
• wherein in the second configuration, the clamp is engaged with the housing to fixedly connect the housing with the frame to maintain a fixed distance between the distal edge of the cutting surface and the first axis.
