Abstract
Abstract A veneer peeling machine has a frame in which three rollers are mounted for rotation thereby to rotate a log between them. Two of the rollers are movable towards the third roller as the diameter of the log is reduced by peeling. A knife is movable to engage the log and peel a veneer from it, and the third roller, or preferably a fourth roller mounted close to the third roller in a fluid bearing extending along the length of the fourth roller, engages the log closely ahead of the knife edge to function as a nose bar.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
80 words
A veneer peeling machine comprising a frame, three rollers, means mounting said rollers in said frame for rotation on mutually parallel axes, first and second of the rollers being so mounted and so movable relative to each other and to the third roller as to grip and rotate a log disposed between the three rollers, a knife and means supporting the knife relative to a said log to peel a veneer therefrom as the log is rotated by the rollers.
Claim 2
Dependent Claim
80 words
A veneer peeling machine comprising a frame, three rollers, means mounting said rollers in said frame for rotation on mutually parallel axes, first and second of the rollers being so mounted and so movable relative to each other and to the third roller as to grip and rotate a log disposed between the three rollers, a knife and means supporting the knife relative to a said log to peel a veneer therefrom as the log is rotated by the rollers.
Claim 3
Dependent Claim
94 words
A veneer peeling machine comprising a frame, three rollers, means mounting the rollers for rotation in the frame with their axes disposed parallel to one another and spaced apart to receive a log therebetween, means for rotating first and second of the rollers in the same rotational direction thereby to rotate a log between the rollers, means for urging the first and second rollers toward the third roller to press the log against the third roller, a knife and means for moving the knife to engage and peel a veneer from a said log.
Claim 4
Dependent Claim
94 words
A veneer peeling machine comprising a frame, three rollers, means mounting the rollers for rotation in the frame with their axes disposed parallel to one another and spaced apart to receive a log therebetween, means for rotating first and second of the rollers in the same rotational direction thereby to rotate a log between the rollers, means for urging the first and second rollers toward the third roller to press the log against the third roller, a knife and means for moving the knife to engage and peel a veneer from a said log.
Claim 5
Dependent Claim
112 words
A veneer peeling machine comprising a frame, three rollers, means mounting the rollers for rotation in the frame with their axes disposed parallel to one another, said means enabling the rollers to move relative to each other so as to grip and rotate a log disposed between the three rollers, means for urging first and second of the rollers toward the third roller to press the log against the third roller, a nose bar and a knife having a cutting edge and means mounting said nose bar and knife for movement into a position adjacent the third roller to enable the knife to engage and peel a veneer from a said log.
Claim 6
Dependent Claim
112 words
A veneer peeling machine comprising a frame, three rollers, means mounting the rollers for rotation in the frame with their axes disposed parallel to one another, said means enabling the rollers to move relative to each other so as to grip and rotate a log disposed between the three rollers, means for urging first and second of the rollers toward the third roller to press the log against the third roller, a nose bar and a knife having a cutting edge and means mounting said nose bar and knife for movement into a position adjacent the third roller to enable the knife to engage and peel a veneer from a said log.
Claim 7
Dependent Claim
52 words
A machine according to claim 3 wherein said means mounting said nose bar and knife enable the cutting edge of the knife and said nose bar to move in a plane parallel to the axes of the rollers, the plane containing lines equidistant from the axes of the first and second rollers.
Claim 8
Dependent Claim
22 words
A machine according to claim 4 wherein the nose bar includes a fourth roller which forms the nose of said nose bar.
Claim 9
Dependent Claim
21 words
A machine according to claim 5 including fluid bearing means wherein the fourth roller is mounted along substantially its whole length.
Claim 10
Dependent Claim
26 words
A machine according to claim 3 wherein the means for rotating the rollers comprise a motor connected to the first and second rollers through drive couplings.
Claim 11
Dependent Claim
26 words
A machine according to claim 3 wherein the diameter of the third roller is substantially less than the individual diameters of the first and second rollers.
Claim 12
Dependent Claim
49 words
A machine according to claim 3 wherein the third roller is movable toward the plane containing the cutting edge of the knife and the axis of the log in response to reduction of the diameter of the log and the consequent inward movement of the first and second rollers.
Claim 13
Dependent Claim
28 words
A machine according to claim 8 including fluid bearing means which extend over substantially the whole length of the third roller and wherein the third roller is supported.
