Abstract
A printing plate bender for forming shaped edges on a substrate. The printing plate bender generally has a frame, and an elongate mandrel rotatably supported on the frame. The mandrel includes a substrate retainer supported thereon for securing the substrate thereto. The plate bender includes a first substrate guide supported on the frame and disposed adjacent to the mandrel. The printing plate bender further includes a heater disposed in longitudinal alignment with the mandrel and operatively connected with the mandrel. The heater is movably mounted to the frame and upon rotation of the mandrel is movable to a position wherein the heater is in close proximity to the substrate secured to the mandrel in order to assist in forming the desired bend on the printing plate.
Claims33
A printing plate bender for forming shaped edges on a substrate comprising:
- a frame;
- an elongate mandrel rotatably supported on the frame, the mandrel having a first substrate retainer supported thereon;
- a first substrate guide supported on the frame and disposed adjacent the mandrel;
- and
- a heater disposed in longitudinal alignment with the mandrel, the heater movably mounted on the frame and being movable between a first position spaced from the mandrel and a second position wherein the heater is in close proximity to a substrate securable to the mandrel, thereby forming the shaped edge on the substrate, the heater being operatively connected to the mandrel such that rotation of the mandrel causes movement of the heater.
A printing plate bender for forming shaped edges on a printing plate comprising:
- a frame;
- an elongate mandrel rotatably supported on the frame, the mandrel having a first longitudinally extending slot thereon sized to receive an edge of the printing plate;
- a drive shaft extending from the mandrel and connected to an eccentric cam;
- a elongate guide roller rotatably supported on the frame and disposed adjacent to the mandrel, the first guide roller being in rolling engagement with the mandrel;
- a second elongate guide roller rotatably supported on the frame and disposed adjacent the mandrel opposite from the first guide roller, the second guide roller being in rolling engagement with the mandrel;
- and
- a heater disposed in longitudinal alignment with the mandrel, the heater movably mounted on the frame and connected to a cam follower, the cam follower being in operative engagement with the cam, wherein rotation of the cam causes the heater to move from a first position spaced from the mandrel to a second position wherein the heater is in close proximity to the printing plate securable to the mandrel, thereby forming the shaped edge on the printing plate.
A printing plate bender for forming shaped edges on a substrate comprising:
- a frame;
- an elongate mandrel rotatably supported on the frame, the mandrel having a substrate retainer supported thereon;
- a first guide supported on the frame and disposed adjacent the mandrel;
- and
- a heater disposed in longitudinal alignment with the mandrel and movably mounted on the frame;
- and
- a linkage means for operatively connecting the mandrel to the heater, whereby rotation of the mandrel moves the heater between a first position spaced from the mandrel and a second position wherein the heater is in close proximity to a substrate securable to the mandrel, thereby forming the shaped edge on the substrate.
A printing plate bender comprising:
- a frame;
- an elongate mandrel rotatably supported on the frame, the mandrel including a printing plate retainer being adapted to releasably secure a printing plate to the mandrel;
- a first guide supported on the frame and disposed adjacent the mandrel;
- a heater disposed adjacent the mandrel and being movably supported on the frame;
- and
- a linkage connecting the mandrel to the heater such that rotation of the mandrel causes the heater to move relative to the mandrel.
A printing plate bender for forming shaped edges on a substrate comprising:
- a frame;
- an elongate mandrel rotatably supported on the frame, the mandrel having a first and second substrate retainer supported thereon;
- a first elongate guide roller rotatably supported on the frame and disposed adjacent the mandrel;
- and
- a heater disposed in longitudinal alignment with the mandrel, the heater movably mounted on the frame and being movable between a first position spaced from the mandrel and a second position wherein the heater is in close proximity to a substrate securable to the mandrel, thereby forming the shaped edge on the substrate, the heater being operatively connected to the mandrel such that rotation of the mandrel causes movement of the heater.
A printing plate bender as defined in claim 30, wherein the first substrate retainer includes a longitudinally extending slot formed in the mandrel adapted to receive the edge of the substrate.
A printing plate bender as defined in claim 32, wherein the second substrate retainer includes a longitudinally extending slot formed in the mandrel adapted to receive the edge of the substrate.
