Abstract
Abstract A contour cutter comprises an endless flexible blade (22) supported by a frame (10) such that the blade extends around an endless path, the blade being exposed at two locations. Two blocks of material (29,30) can be positioned one at each location, supported by a table (23). The frame (10) can be moved relative to the table (23) according to a predetermined pattern (31) so that the blade (22) cuts from each block (29,30) a piece of material having the same contour asthe pattern 31.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A contour cutter comprising an endless flexible,blade (22), first support means (10) to support the blade such that the blade extends around an endless path, and means to drive the blade (22) around the endless path, characterised in that the blade (22) is exposed at at least two separate locations on the path, there are second support means (23) to support a block of material one at each location, and there are means (25, 26) to bring about relative movement between the first (10) and second support means (23) according to a predetermined pattern (31) so that the blade (22) simultaneously cuts at least two blocks of material into a shape having a desired contour.
Claim 2
Dependent Claim
115 words
A contour cutter comprising an endless flexible,blade (22), first support means (10) to support the blade such that the blade extends around an endless path, and means to drive the blade (22) around the endless path, characterised in that the blade (22) is exposed at at least two separate locations on the path, there are second support means (23) to support a block of material one at each location, and there are means (25, 26) to bring about relative movement between the first (10) and second support means (23) according to a predetermined pattern (31) so that the blade (22) simultaneously cuts at least two blocks of material into a shape having a desired contour.
Claim 3
Dependent Claim
20 words
A contour cutter as claimed in Claim 1, in which the blade (22) comprises a wire having an abrasive surface.
Claim 4
Dependent Claim
28 words
A contour cutter as claimed in Claim 1 or Claim 2, in which the blade (22) is exposed at at least two opposite sides of the endless path.
Claim 5
Dependent Claim
49 words
A contour cutter as claimed in Claim 3, in which, where the blade (22) is exposed at one side of the endless path that part of the path is parallel to that part of the path where the blade (22) is exposed at the opposite side of the path.
Claim 6
Dependent Claim
77 words
A contour cutter as claimed in Claim 4, in which the first support means (10) is mounted on a carriage (15) for pivotal movement about an axis (14) which is parallel to the said parallel parts of the path, the carriage (15) being movable in a direction which is perpendicular to the said axis (14) and which lies in a plane which is coincident with or parallel to the plane containing the said parts of the path.
Claim 7
Dependent Claim
26 words
A contour cutter as claimed in Claim 5, in which the said axis (14) is horizontal and the carriage (15) is movable in a horizontal plane.
Claim 8
Dependent Claim
58 words
A contour cutter as claimed in any one of Claims 1 to 4, in which the first support means (10) is mounted on means (32) which enable the blade to be moved upwardly and downwardly with the plane containing the said path remaining horizontal, the second support means (23) being movable to and fro in a horizontal plane.
Claim 9
Dependent Claim
27 words
A contour cutter as claimed in Claim 7, in which the first support means (10) is mounted for vertical movement on one or more guide pillars (32).
