Abstract
The present invention includes apparatus for retaining a tapered flitch, having a generally semi-cylindrical veneer-producing zone, on a staylog for movement past a veneer-slicing knife, wherein the tapered flitch includes an axis of rotation. The apparatus comprisesstationary dogs coupled to the staylog for engaging the flitch and movable dogs for moving the flitch into engagement with the stationary dogs to hold the flitch on the staylog. The flitch is held on the staylog so that the axis of rotation of the veneer-producing zone is in a parallel relation with the veneer-slicing knife in order to minimize the amount of waste veneer taken from the veneer-producing zone.
Claims23
An apparatus for retaining a tapered flitch on a staylog for movement past a veneer-slicing knife, with the flitch providing a generally semi-cylindrical veneer-producing zone having an axis of rotation and the staylog including a staylog mounting surface, the apparatus comprising:
- stationary dog means coupled to the staylog for engaging the flitch, and
- means for moving the flitch into engagement with the stationary dog means to hold the flitch on the staylog with the axis of rotation of the veneer-producing zone in a parallel relation with the veneer-slicing knife so as to minimize the amount of waste veneer taken from the veneer-producing zone.
A method of retaining a flitch on a staylog for slicing veneer from the flitch, the staylog having a plurality of stationary pin dogs, the method comprising the steps of:
- providing a flitch having a first plurality of holes for receiving a plurality of stationary pin dogs,
- positioning the plurality of stationary dogs in the first plurality of holes, and
- moving the flitch into engagement with the dogs to retain the flitch on the staylog.
An apparatus for retaining a flitch on a staylog, the flitch including a plurality of holes formed in a flitch mounting surface, the apparatus comprising:
- a staylog for carrying the flitch,
- a plurality of dogs attached to the staylog and positioned to be received by a first group of the plurality of holes for engaging the flitch, and
- a plurality of pusher pins attached to the staylog and positioned to be received by a second group of the plurality of holes for moving the flitch into engagement with the plurality of dogs to retain the flitch on the staylog.
An apparatus for retaining a flitch for slicing, comprising:
- a staylog having a plurality of predetermined positions, and
- a plurality of knife edges located at the predetermined positions for engaging the flitch to retain the flitch on the staylog,
- wherein the number of knife edges engaging 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 first portion for engaging a staylog, and
- a second portion having a plurality of annular knife edges for engaging the flitch, the knife edges being axially spaced-apart along a longitudinal axis of the dog.
A method of retaining a flitch on a staylog for slicing veneer from the flitch, the staylog having a plurality of dogs, the method comprising the steps of:
- providing a flitch having a plurality of holes for receiving the plurality of dogs, the holes having a depth profile and the dogs having a flitch engaging portion configured to generally conform to the depth profile, the flitch-engaging portion including a plurality of flitch-engaging surfaces,
- positioning the plurality of dogs in the plurality of holes, and
- engaging the flitch with at least one of the plurality of flitch-engaging surfaces on each of the plurality of dogs to retain the flitch on the staylog with a veneer-producing zone maintained in parallel relation to a veneer-slicing knife.
