Abstract
Abstract Apparatus for cutting and notching layups of sheet material includes a layup support means and a main carriage slidably mounted for movement in a first coordinate direction relative to such support means. First and second cutting heads are movably supported on the carriage for movement therewith in said first coordinate direction and for movement with respect thereto in at least one other coordinate direction. The carriage as well as the first and second cutting heads move in response to positioning signals supplied by a computerized controller. A first movable blade or cutting tool is driven by the first cutting head and is adapted to engage the layup to form a cut thereon as the cutting head is moved in a plane parallel to the layup. A second blade or cutting tool is driven from the second cutting head and is adapted to move in a plunging fashion relative to the layup to form a notch or cut therein.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
An apparatus for cutting sheet material, said apparatus comprising means defining a material supporting surface, a main carriage supported for movement in a first coordinate direction relative to said supporting surface, a first cutting head carried by said main carriage for movement therewith in said first coordinate direction and movable relative thereto in a second coordinate direction, said first cutting head including a linear cutting tool adapted to engage sheet material supported on said supporting surface and to cut it along a line as it is moved in the plane of said supporting surface, and a second cutting head carried by said main carriage for movement therewith in said first coordinate direction and movable relative thereto in said second coordinate direction, said second cutting head including a notch cutting tool adapted to plunge into and out of sheet material supported on said supporting surface to cut a notch therein while said second cutting head is held stationary in the plane of said supporting surface.
Claim 2
Independent Claim
164 words
An apparatus for cutting sheet material, said apparatus comprising means defining a material supporting surface, a main carriage supported for movement in a first coordinate direction relative to said supporting surface, a first cutting head carried by said main carriage for movement therewith in said first coordinate direction and movable relative thereto in a second coordinate direction, said first cutting head including a linear cutting tool adapted to engage sheet material supported on said supporting surface and to cut it along a line as it is moved in the plane of said supporting surface, and a second cutting head carried by said main carriage for movement therewith in said first coordinate direction and movable relative thereto in said second coordinate direction, said second cutting head including a notch cutting tool adapted to plunge into and out of sheet material supported on said supporting surface to cut a notch therein while said second cutting head is held stationary in the plane of said supporting surface.
Claim 3
Dependent Claim
34 words
An apparatus for cutting sheet material as set forth in claim 1 wherein said means defining said material supporting surface comprises a bed of material which is readily penetrated by said notch cutting tool.
Claim 4
Dependent Claim
52 words
An apparatus for cutting sheet material as set forth in claim 1 wherein said notch cutting tool is a blade having a sharp cutting point directed toward said supporting surface and at least one sharp cutting edge intersecting said point and extending therefrom in its direction generally away from said supporting surface.
Claim 5
Dependent Claim
25 words
An apparatus for cutting sheet material as set forth in claim 3 wherein said cutting edge extends throughout substantially the entire length of said blade.
Claim 6
Dependent Claim
25 words
An apparatus for cutting sheet material as set forth in claim 3 wherein said cutting point of said blade is formed by four converging planes.
Claim 7
Dependent Claim
30 words
An apparatus for cutting sheet material as set forth in claim 1 wherein said notch cutting tool is a blade at least partially coated with a low friction plastic material.
Claim 8
Dependent Claim
20 words
An apparatus for cutting sheet material as set forth in claim 6 wherein said blade is made from tungsten carbide.
Claim 9
Dependent Claim
20 words
An apparatus for cutting sheet material as set forth in claim 6 wherein said low friction plastic material is polytetrafluoroethylene.
Claim 10
Dependent Claim
80 words
An apparatus for cutting sheet material as set forth in claim 1 wherein said notch cutting tool comprises a blade having a sharp cutting point directed toward said supporting surface, a first longitudinal cutting edge along a first side thereof, a second longitudinal cutting edge extending from said first edge to said cutting point, and a third longitudinal cutting edge extending along a second diametrically opposite side of said blade, said second and third edges intersecting at said cutting point.
Claim 11
Dependent Claim
58 words
An apparatus for cutting sheet material as set forth in claim 1 further including first and second stripper meaNs mounted on said first and second cutting heads and located respectively adjacent said linear cutting tool and said notch cutting tool so as to be engageable with the top surface of the sheet material received on said supporting surface.
