Abstract
Abstract During grinding of a chamfer on a continuously transported workpiece, an edge with a burr is formed. The burr moves with the workpiece into eccentric engagement with a cutter which is rotated and continuously severs the burr from the edge.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
105 words
Edge burr removal apparatus comprising, in combination, supporting means including guide means for guiding in one direction a workpiece having intersecting faces forming an edge extending in said direction and having a burr transversely projecting from said edge; and a cutter mounted on said supporting means for rotation about an axis transverse to said edge, and having a peripheral surface of revolution and an end face intersecting at a circular cutting edge concentric with said axis, said supporting means including means for positioning said cutter relative to said guide means so that the cutter end face is crossed by the edge of the said workpiece.
Claim 2
Dependent Claim
105 words
Edge burr removal apparatus comprising, in combination, supporting means including guide means for guiding in one direction a workpiece having intersecting faces forming an edge extending in said direction and having a burr transversely projecting from said edge; and a cutter mounted on said supporting means for rotation about an axis transverse to said edge, and having a peripheral surface of revolution and an end face intersecting at a circular cutting edge concentric with said axis, said supporting means including means for positioning said cutter relative to said guide means so that the cutter end face is crossed by the edge of the said workpiece.
Claim 3
Dependent Claim
47 words
Apparatus as claimed in claim 1 comprising rotary means for making a chamfer on said workpiece during movement of said workpiece in said one direction whereby said edge with said burr thereon is formed on one side of said chamfer directly before said workpiece engages said cutter.
Claim 4
Dependent Claim
54 words
Apparatus as claimed in claim 1 wherein said supporting means include a stationary support, and said positioning means include a carrier means supporting said cutter for rotation about said axis, and being mounted on said support for movement toward and away from said workpiece for moving said cutter to and from a cutting position.
Claim 5
Dependent Claim
38 words
Apparatus as claimed in claim 3 comprising spring means for biassing said carrier means toward said workpiece; and wherein said cutter is biassed by said spring means to abut in said cutting position said edge of said workpiece.
Claim 6
Dependent Claim
32 words
Apparatus as claimed in claim 3 wherein said carrier means includes a lever supporting said cutter at one end thereof, and being mounted on said support for angular movement about an axis.
Claim 7
Dependent Claim
32 words
Apparatus as claimed in claim 5 wherein said support includes means for mounting said lever for angular movement about an axis parallel with said one direction; and wherein said edge is straight.
Claim 8
Dependent Claim
35 words
Apparatus as claimed in claim 5 wherein said support includes means for mounTing said lever for angular movement about an axis defining an acute angle with said one direction; and wherein said edge is straight.
Claim 9
Dependent Claim
42 words
Apparatus as claimed in claim 3 and wherein said support includes adjustable means for holding said carrier means in such a position that said cutting edge in said cutting position projects only slightly beyond the plane of a face of said workpiece.
Claim 10
Dependent Claim
40 words
Apparatus as claimed in claim 1 wherein said cutter has a support portion mounted on said supporting means for rotary movement about said axis, and a cutting portion secured to said support portion, and including a hard, wear resistant material.
Claim 11
Dependent Claim
48 words
Apparatus as claimed in claim 9 wherein said cutting portion is a thin circular disk having a circular peripheral cutting edge; and wherein said support portion of said cutter has said surface of revolution adjacent the periphery of said disk and having the same diameter as the same.
Claim 12
Dependent Claim
18 words
Apparatus as claimed in claim 1 wherein said end face is planar and surrounded by said cutting edge.
Claim 13
Dependent Claim
18 words
Apparatus as claimed in claim 1 wherein said end face is concave and surrounded by said cutting edge.
Claim 14
Dependent Claim
33 words
Apparatus as claimed in claim 1 comprising drive means for rotating said cutter about said axis so that said cutter is rotated independently of the movement of said workpiece in said one direction.
