Abstract
A veneer slicer includes a mandrel for holding multiple flitches. The mandrel has a first axis about which it is rotated. A knife and pressure bar assembly is provided on a first reciprocable carriage. The carriage is reciprocated toward and away from the first axis of rotation as the flitches are carried around the first axis of rotation on the mandrel. The mandrel is reciprocated along the first axis of rotation. Rotation of the mandrel, coupled with reciprocation of the carriage and mandrel respectively toward and away from the first axis of rotation and along the first axis of rotation, causes veneer to be sliced sequentially from the multiple flitches.

In a veneer slicer comprising a mandrel for holding multiple flitches, the mandrel having a first axis of rotation, means for rotating the mandrel, a knife and pressure bar assembly, a carriage and means for reciprocating the carriage toward the first axis of rotation as the flitches are carried around the first axis of rotation on the mandrel for reciprocating the knife and pressure bar assembly toward the first axis of rotation of the mandrel, rotation of the mandrel by the means for rotating the mandrel, coupled with reciprocation of the carriage toward the first axis of rotation as the flitches are carried around the first axis of rotation causing veneer to be sliced sequentially from said multiple flitches, means for movably mounting the knife and pressure bar assembly on the carriage and a linear fluid motor for moving the knife and pressure bar assembly with respect to the carriage, the fluid motor having two ends, the fluid motor fixed at a first of its ends to the carriage and at a second of its ends to the knife and pressure bar assembly.
In a veneer slicer comprising a mandrel for holding a flitch, the mandrel having a first axis of rotation, means for rotating the mandrel, a knife and pressure bar assembly, a carriage, and means for reciprocating the carriage toward and away from the first axis of rotation as the flitch is carried around the first axis of rotation on the mandrel for reciprocating the knife and pressure bar assembly toward and away from the first axis of rotation of the mandrel to provide sheets of veneer having selected different profiles transverse to their lengths, means for movably mounting the knife and pressure bar assembly on the carriage and a linear fluid motor for moving the knife and pressure bar assembly with respect to the carriage, the fluid motor having two ends, the fluid motor fixed at a first of its ends to the carriage and at a second of its ends to the knife and pressure bar assembly.
In a veneer slicer comprising a mandrel for holding multiple flitches, the mandrel having a first axis of rotation, means for rotating the mandrel, a knife and pressure bar assembly, a first reciprocable carriage and first means for reciprocating the carriage toward the first axis of rotation as the flitches are carried around the first axis of rotation on the mandrel for reciprocating the knife and pressure bar assembly toward the first axis of rotation of the mandrel, and at least one linear fluid motor for reciprocating the mandrel along the first axis of rotation of the mandrel, rotation of the mandrel by the means for rotating the mandrel, coupled with reciprocation by the first means for reciprocating the first carriage and the at least one linear fluid motor for reciprocating the mandrel respectively toward the first axis of rotation and along the first axis of rotation as the flitches are carried around the first axis of rotation causing veneer to be sliced sequentially from said multiple flitches.
In a veneer slicer comprising a mandrel for holding a flitch, the mandrel having a first axis of rotation, means for rotating the mandrel, a knife and pressure bar assembly, a first carriage, first means for reciprocating the first carriage toward the first axis of rotation as the flitch is carried around the first axis of rotation on the mandrel for reciprocating the knife and pressure bar assembly toward the first axis of rotation of the mandrel, and at least one linear fluid motor for reciprocating the mandrel along the first axis of rotation of the mandrel.
