Abstract
A method and apparatus for retaining a flitch on a staylog or slicer for slicing veneer from the flitch, the staylog or slicer having a plurality of expandable wedge-clamp dogs, the method comprising the steps of providing a flitch having a plurality of dados for receiving a plurality of wedge-clamp dogs, positioning the plurality of wedge-clamp dogs within the plurality of dados in the flitch, and expanding the wedge-clamp dogs to retain the flitch on the staylog or slicer.
Claims21
1-18. (canceled)
A dog for retaining a flitch for cutting, comprising:
- a pair of clamp plates for engaging the flitch, each having a T-bolt that is moveably engageable with a staylog;
- and
- means for expanding the pair of clamp plates to engage the flitch to hold the flitch on a staylog.
A method for retaining a flitch on a vertical reciprocating slicer for slicing veneer from the flitch, the slicer having a plurality of expandable wedge-clamp dogs, comprising the steps of
- providing a flitch having a plurality of dados for receiving a plurality of wedge-clamp dogs;
- positioning the plurality of wedge-clamp dogs within the plurality of dados in the flitch;
- and
- expanding the wedge-clamp dogs to retain the flitch on the slicer.
The method of claim 23 wherein the expanding step further includes a hydraulically driven wedge that expands the wedge-clamp dogs to retain the flitch on the slicer.
A method of retaining a flitch on a vertical reciprocating slicer for slicing veneer from the flitch, the slicer having a plurality of wedge-clamp dogs, comprising the steps of
- providing a flitch having a plurality of dados for receiving the plurality of wedge-clamp dogs, the holes having a depth profile and the wedge-clamp dogs having flitch engaging portions configured to generally conform to the depth profile;
- positioning the plurality of wedge-clamp dogs in the plurality of dados;
- and
- engaging the flitch with the wedge-clamp dogs to retain the flitch on the slicer with a veneer producing zone maintained in parallel relation to a veneer slicing knife.
An apparatus for retaining a flitch with a tapered veneer producing face on the mounting surface of a vertical reciprocating slicer for the passing movement of a veneer slicing knife, comprising
- wedge-clamp dogs for extending from the mounting surface of the slicer for engaging the flitch, and
- means for expanding the wedge-clamp dogs when engaged with the flitch to hold the flitch on the slicer with the tapered veneer producing face of the flitch in a parallel relationship with the veneer slicing knife so as to minimize the amount of waste veneer taken from the tapered veneer producing face of the flitch.
An apparatus for retaining a flitch on a vertical reciprocating slicer, the flitch including a plurality of dados formed in the flat underside surface thereof, comprising:
- a slicer for carrying the flitch;
- a plurality of wedge-clamp dogs attached to the slicer and positioned to be received by the plurality of dados formed in the flat underside of the flitch for engaging the flitch, and
- means for expanding the wedge-clamp dogs when engaged with the flitch to hold the flitch on the slicer.
An apparatus for retaining a flitch for slicing, comprising:
- a vertical reciprocating slicer having a mounting surface with a plurality of predetermined positions, and
- a plurality of wedge-clamp dogs located at the predetermined positions for engaging the flitch to retain the flitch on the staylog, wherein the distance between the mounting surface and the flitch at a predetermined position is proportional to the thickness of the flitch at the predetermined position.
A dog for retaining a flitch for cutting, comprising:
- a pair of clamp plates for engaging the flitch, each having a T-bolt that is moveably engageable with a vertical reciprocating slicer;
- and
- means for expanding the pair of clamp plates to engage the flitch to hold the flitch on a slicer.
