Abstract A method and a mechanism for feeding waned boards to an edger comprising a cross conveyor for the boards, a measuring apparatus, a computer, and centering and side-adjustment means to enable centering and side-adjustment of the boards in dependence of the determined values to optimize the yield in the edger. Adjacent the outlet end of the cross conveyor there are provided slide planes (i.e. movable planar support surfaces on which the boards can slide or be slid) which form a part of a longitudinal infeed conveyor and which are adapted to receive the boards from the cross conveyor and to support the boards during the centering and side-adjustment. The slide planes can be lowered or removed, after the centering and side-adjustment has been carried out, in a manner to place the board on a longitudinal conveyor means of the infeed conveyor to be fed into the edger. Preferably the longitudinal conveyor means are stationary during adjustment and are then accelerated in a controlled manner.
Apparatus for feeding waned boards to an edger, comprising: (a) a cross-conveyor for moving the boards individually in a direction transverse to the length; (b) automatic means for taking measurements of the boards one at a time while on said cross-conveyor; (c) a computer connected to said means to store and process the measurements, and being adapted to be programmed to optimize yield; (d) slide planes disposed adjacent to the discharge end of said cross-conveyor for receiving individual boards therefrom and for supporting each board; (e) means for centering and side-adjusting each board on said slide planes, and being controlled by said computer in response to the measurements of that board; (f) a longitudinal conveyor disposed to received boards from said slide planes and to transfer boards to the edger; (g) means for lowering said slide planes to thereby transfer the board on said slide planes onto said longitudinal conveyor; and (h) means for maintaining the adjusted orientation of each board as it enters the edger.
