Abstract: A knife assembly for cutting a substrate during relative motion between the knife and the substrate, the assembly including a knife having a distal knife blade and a proximal knife shaft attached to a holder rotatable about a first axis perpendicular to the substrate to define a cut direction angle. The holder is also configured to rotate the knife blade about a second axis perpendicular to the first axis to form a notch angle relative to the first axis. The notch angle is preferably automatically infinitely adjustable within a range of angles. The holder may also, optionally, be configured to rotate the knife blade about a third axis perpendicular to a plane defined by the knife blade to adjust an angle of attack of the knife blade relative to the substrate.

Abstract: A separator (10) for separating waste (820) from product (810; 2302) in a pre-cut substrate (2600) having one or more cut lines. An inlet feeder feeds the substrate (2600) into the separator (10) along a material path. A separation edge (2500) is disposed in a location downstream of the inlet feeder and defines a line below the plane of the material path. A plurality of punch tools (30; 1800; 1900; 2000) above the plane of the material path, upstream of the separation edge (2500), each has an actuator configured to position the tool in an extended configuration with a contact end of the punch tool (30; 1800; 1900; 2000) disposed below the separation edge (2500), and a retracted configuration with the contact end disposed above the plane of the material path. A controller commands each actuator to position the corresponding punch tool (30; 1800; 1900; 2000) contact end synchronized with the position of the pre-cut substrate (2600) to cause the separation edge (2500) to separate the waste (820) from the product (810; 2302) along the cut lines.
