Abstract
Methods and apparatus for using a veneer type lathe of compact design for the pellitizing of a log portion directly from the log without intermediate steps. A log saddle with slide guides for the axles of the incisor rolls enables a significant reduction in the complexity of a peripheral drive veneer lathe and permits the use of a single press to clamp, incise and separate the pellets from the log.
Claims12
A pellitizer of the veneer lathe type comprising,
- a press having a frame including a first compression exerting member and compression resisting members and a space between said members for receiving a log portion for compressing and peeling therein;
- a log saddle including a veneer knife assembly and a nose bar mounted thereto, said log saddle being in said space between said members, said log saddle including an elongated frame portion having end plates, said end plates having a pair of symmetrical slide glides therein;
- a plurality of incisor rolls, each said roll having an axle, each said roll having sharp edges in its surface for incising the periphery of a said log portion, each said axle of each said roll being mounted in a pair of said end plate guide slides, said axles being parallel to one another;
- and
- in operation, said first compression exerting member of said press being connectable to said log saddle, for providing force to each said axle of said rolls when a log is in contact position with said nose bar and said rolls, wherein said rolls are automatically forced to become positioned equally spaced about the periphery of a log portion by the action of said symmetrical guide slides responsive to the force provided by said first compression exerting member.

A pellitizer lathe comprising:
- a plurality of parallel rolls, each said roll having an axle, said plurality of rolls including at least two incissor rolls, each said incissor roll having sharp edges at its surface for incising the periphery of a workpiece placed between said rolls;
- press means for pinching said plurality of rolls to clamp a workpiece therebetween, said press means for pinching comprising a press having a frame including a first compression exerting member and compression resistance members and futher including means to couple said compression exerting member to said axles;
- a knife means, said knife means including an elogated edge parallel to said axles;
- means for rotating a said workpiece at the same time it is being pinched;
- and
- means for making a veneer type cut in said workpiece with said knife means.

A pellitizer lathe comprising:
- a plurality of parallel rolls, each said roll having an axle, said plurality of rolls including at least two incissor rolls, each said incissor roll having sharp edges at its surface for making an incision in the periphery of a workpiece placed between said rolls;
- means for pinching said rolls including axle guide means;
- a knife means, said knife means including an elogated edge parallel to said axles;
- means for rotating a said workpiece at the same time it is being pinched to incise the workpiece periphery;
- and
- means for making a veneer type cut in said workpiece with said knife means to a depth less than the depth of said incision made by said incissor rolls.
