Abstract
An engraver having an engraving head is provided wherein replaceable components, such as tools, of the engraving head are formed with a cartridge-style construction. For example, in one aspect of the engraving head, a cartridge-type diamond stylus is provided having a trapezoidal cross-section for facilitating positive registration and positioning of the stylus within the engraving head. Other tools, such as a shoe and/or burr cutter may also be provided in a detachable cartridge arrangement to facilitate quick mounting and replacement of an existing shoe or burr cutter, respectively, such that the shoe or burr cutter also becomes aligned and registered on the engraving head.

A shoe assembly for use on an engraving head in an engraving apparatus, said shoe assembly comprising:
- a support situated on said engraving head;
- and
- a shoe means detachably secured to said support such that when said shoe means is secured to said support, said shoe means becomes self-aligned on said engraving head.
A shoe assembly for use in an engraving head of an engraver wherein said shoe assembly is adapted to engage a surface to be engraved to maintain a predetermined spacing between said engraving head and said surface, said shoe assembly comprising:
- a support arm;
- and
- a shoe tool detachably supported on said support arm such that when said shoe tool is secured to said support arm, said shoe tool becomes registered in said engraving head.
A method of positioning an engraving head relative to a surface to be engraved, including the steps of:
- providing a shoe tool that becomes registered when mounted on said engraving head;
- mounting said shoe tool on said engraving head;
- and
- moving said shoe tool into contact with a surface to be engraved whereby said shoe tool is caused to self align with said surface to be engraved.
A burr cutting assembly for use in an engraving apparatus for engraving a cylinder having an axis, said cutting assembly comprising:
- tool means having a cutting edge for cutting and removing burrs on an engraved surface;
- driver means for moving said tool means axially such that the cutting edge is moved into operative relationship with a desired location on a surface of said cylinder;
- and
- a controller operatively connected to said driver means wherein said controller is operable for energizing said driver means to move said cutting edge into said operative relationship.
A burr cutting assembly for use in an engraving apparatus for engraving a cylinder having an axis, said cutting assembly comprising:
- tool means having a cutting edge for engaging and cutting burrs on an engraved surface;
- driver means for moving said tool means axially such that the cutting edge is moved into operative relationship with a desired location on a surface of said cylinder;
- and
- a controller operatively connected to said driver means wherein said controller is operable for energizing said driver means to move said cutting edge into said operative relationship;
- wherein said tool means includes a substantially planar facing surface inclined at an acute angle relative to said axis and said cutting edge is curved and lies in a plane defined by said facing surface.
A burr cutting assembly for use in an engraving head of an engraver for engraving a cylinder having an axis, said cutting assembly comprising:
- a tool having a cutting edge;
- a tool holder for supporting said tool in engagement with the surface of a cylinder;
- a driver for supporting said tool holder, said driver being operable to move said tool holder relative to said cylinder;
- a controller operatively connected to said driver;
- and
- wherein said cutting edge is curved and is inclined at an acute angle relative to said axis and said controller is operable to actuate said driver for automatically positioning said cutting edge into tangential engagement with a desired location on a surface of said cylinder.
A method of removing burrs from a plurality of engraved cylinders, including the steps of:
- providing a tool having a curved cutting edge;
- supporting said cutting edge in contact with the surface of a cylinder at an angle relative to an axis of said cylinder;
- providing a driver for moving said tool to a desired location relative to said cylinder;
- providing a controller operatively connected to said driver for actuating said driver to move said cutting edge to a desired location on said cylinder;
- and
- rotating said cylinder past said tool to thereby remove burrs.
An engraving head for engraving a plurality of cylinders, said engraving head comprising:
- a stylus assembly including a stylus arm having means defining an aperture, a stylus cartridge mounted in said aperture for engraving cells in the surface of a cylinder, and an end wall located at an end of said aperture for engaging an end of said stylus cartridge whereby said stylus cartridge is located in a predetermined location on said stylus arm;
- a shoe assembly including a support arm and a shoe tool supported on said support arm, said shoe tool including at least on non-planar contact surface for engaging said surface of a cylinder;
- and
- a burr cutting assembly including a cutting tool having a cutting edge and a tool holder for supporting said cutting tool in engagement with said surface of a cylinder wherein said cutting edge is curved such that said cutting edge is capable of engaging a plurality of cylinder surfaces in tangential relationship.
An engraver for engraving a cylinder, said engraver comprising:
- an engraving head;
- a sensor mounted on said engraving head for sensing the position of said engraving head relative to a cylinder and for generating a feedback signal corresponding thereto;
