Single revolution die cutter

A rotary die cutter adapted for cutting out images from product sheets, comprising:

• (a) a frame;
• (b) an anvil roll revolvably attached to said frame, said anvil roll having a cylindrical body;
• (c) a die roll revolvably attached to said frame, said die roll having a cylindrical body in operable contact with said cylindrical body of said anvil roll, said die roll being equipped with tooling constructed and arranged to cut out images from said product sheets, each of said product sheets being fed between said anvil roll and said die roll, said die roll being equipped with at least one spring-loaded pin, said at least one pin retracting into said cylindrical body of said die roll, said at least one pin stopping each of said product sheets in a predetermined location with respect to said tooling to register each of said product sheets to be properly cut by said tooling;
• (d) a drive mechanism for revolving said anvil roll and said die roll;
• and
• (e) an engagement mechanism for selectively engaging and disengaging said drive mechanism from driving said anvil roll and said die roll, said engagement mechanism including a single revolution clutch attached to said anvil roll.

A single revolution rotary die cutter, comprising:

• (a) a frame including a pair of opposing anvil bearing blocks attached to a base plate and a pair of opposing die bearing blocks attached to said pair of anvil bearing blocks, said pair of die bearing blocks being constructed and arranged to be quickly detached from and reattached to said pair of anvil bearing blocks;
• (b) an anvil roll extending between said pair of anvil bearing blocks, said anvil roll having a cylindrical body, said anvil roll having a first end and a second end, each of said ends of said anvil roll being revolvably attached to one of said anvil bearing blocks;
• (c) a die roll extending between said pair of die bearing blocks, said die roll having a cylindrical body in operable contact with said cylindrical body of said anvil roll, said die roll having a first end and a second end, each of said ends of said die roll being revolvably attached to one of said die bearing blocks, said die roll being equipped with:
• (i) tooling constructed and arranged to cut product sheets fed between said anvil roll and said die roll;
• and
• (ii) at least one spring-loaded pin, said at least one pin retracting into said body of said die roll when contacting said anvil roll, said at least one pin stopping each of said product sheets in a predetermined location with respect to said tooling to register each of said product sheets to be properly cut by said tooling, said at least one pin being rotatable and eccentric, wherein said predetermined location for stopping each of said product sheets with respect to said tooling is adjustable by rotating said at least one eccentric pin;
• (d) an electric motor for driving said anvil roll and said die roll;
• and
• (e) an engagement mechanism for selectively engaging and disengaging said drive mechanism from driving said anvil roll and said die roll, said engagement mechanism including:
• (i) a single revolution clutch attached to said anvil roll, said clutch having a released state and an engaged state, said drive mechanism driving said anvil roll one revolution when said clutch is in said released state, said clutch having an exterior surface and a tine extending out from said cylindrical surface;
• (ii) a clutch release arm movable between a release position and an engage position, said arm having a notch, wherein said tine is latched with said notch when said arm is in said engage position and said tine is released from said notch of said arm when said arm is in said release position, said arm being biased in said engage position;
• and
• (iii) a solenoid for moving said arm from said engage position to said release position when energized.
