Abstract
Apparatus is disclosed for selectively notching an edge of a material such as photographic film or cutting through the material using the same blade. The material is guided by a path, and the blade is mounted for variable penetration into the path. One or more solenoids are responsive to a first control command for driving the blade a first distance into the path to notch an edge of the material therein, and responsive to a second control command for driving the blade a second distance into the path to cut entirely through the material. The apparatus has particular application as a cutter/notcher for a film recorder.
Claims19
Apparatus for selectively notching a portion of a material or severing said material by cutting entirely through it comprising:
- means for guiding a material along a path;
- a blade mounted for variable penetration into said path;
- and
- automated drive means interconnected with said blade for driving said blade into said path;
- wherein said drive means:
- are selectively actuable to move said blade to a first position to notch a portion of said material and to a second position to sever said material;
- and
- include a first solenoid drivingly engageable with said blade for moving said blade from a rest position outside of said path to said second position, said blade passing through said first position as it travels to said second position.
Apparatus for selectively notching an edge of a photographic film or cutting through said film using the same blade comprising:
- a film path;
- a blade mounted for variable penetration into said path;
- and
- drive means responsive to a first electrical control command for driving said blade a first distance into said path to notch an edge of film in said film path and responsive to a second electrical control command for driving said blade a second distance into said path to cut through film in the film path.
Apparatus for selectively notching a portion of a material or severing said material by cutting entirely through it comprising:
- means for guiding a material along a path;
- a blade mounted for variable penetration into said path;
- and
- automated drive means interconnected with said blade for driving said blade into said path;
- wherein said drive means;
- are selectively actuable to move said blade to a first position to notch a portion of said material and to a second position to sever said material;
- and
- include a solenoid for introducing a stop into the path of said blade for stopping said blade in said first position.
Apparatus for selectively notching a portion of a material or severing said material by cutting entirely through it comprising:
- means for guiding a material along a path;
- a blade mounted for variable penetration into said path;
- and
- automated drive means including a solenoid interconnected with said blade for driving said blade into said path;
- wherein:
- said drive means are selectively actuable to move said blade to a first position to notch a portion of said material and to a second position to sever said material;
- said blade is pivotally coupled at a first end thereof to a plunger shaft of said solenoid and pivotally connected at a second end thereof to a fixed member;
- said apparatus further comprising spring means for biasing said blade into a rest position outside of said path.
