Abstract

Claims (17)

1 . A system for scoring a web of a roll of paper material, the system comprising:

a scoring station frame;

a steel plate operatively associated with the scoring station frame and having one or more slot defining a shape representing an outline of a pressware product;

a steel scoring punch including one or more protruding blade corresponding to the one or more slot of the plate;

a platen supporting the steel scoring punch and having a first surface facing the steel scoring punch and a second surface opposite to the first surface;

one or more toggle block coupled to the platen via one or more biasing element configured to bias the one or more toggle block toward the second surface of the platen;

one or more wedge set positioned between the one or more toggle block and the second surface of the platen and operable to shift along the second surface of the platen, the one or more wedge set having a varied thickness so that shifting the one or more wedge set adjusts a distance between the one or more toggle block and the second surface of the platen;

a height adjust actuator configured to shift the one or more wedge set along the second surface of the platen;

a toggle assembly supported by the scoring station frame and coupled to the one or more toggle block, the toggle assembly operable to extend toward the steel plate; and

a scoring station actuator configured to actuate the toggle assembly so that the toggle assembly shifts toward the steel plate, thereby shifting the scoring punch toward the plate.

2 . The system of claim 1 , further comprising a controller configured to receive a signal representative of a first predetermined scoring depth, and direct the height adjust actuator to shift the one or more wedge set so that the one or more blade reaches the first predetermined scoring depth relative to the one or more slot when the scoring station actuator actuates the toggle assembly.

3 . The system of claim 2 , wherein controller is further configured to—

receive a signal representative of a second predetermined scoring depth, and

direct the height adjust actuator to shift the one or more wedge set so that the one or more blade reaches the second predetermined scoring depth relative to the one or more slot when the scoring station actuator actuates the toggle assembly.

4 . The system of claim 3 , wherein the signal representative of the second predetermined scoring depth is associated with a thickness of the web.

5 . The system of claim 1 , wherein the plate comprises a plurality of additional slots, and the scoring punch comprises a plurality of corresponding additional blades, and the one or more slot and the plurality of additional slots extend radially about the shape representing an outline of a pressware product, and the one or more blade and the plurality of additional blades extend radially about and define a corresponding shape complementary to the shape defined by the slots on the plate.

6 . The system of claim 1 , further comprising a pair of indexer assemblies supported on the scoring station frame for pulling the web between the plate and the scoring punch.
