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.
