ABSTRACT:
An apparatus for feeding individual pieces of timber from a mat of a plurality of interconnected or closely adjacent timber pieces, comprises a feed conveyor for feeding the timber mat through a feed path which, for example, may comprise an inclined plane along which the timber mat moves by gravity. A cam or arm member is oscillated periodically to engage in front of the foremost edge of the foremost piece of the timber mat in order to position it at a location in which it will be engaged by a respective projection member which forms a part of an endless conveyor having a plurality of such projection members which are advantageously formed by pivoting them together. The projection members are shaped in a triangular fashion so that the apex of the triangular part engages directly adjacent the trailing edge of the foremost piece of lumber which is fed along the feed path and it aids in separating this piece from the remaining pieces. In addition, the projection member includes a support surface which is inclined downwardly in the direction of movement of the transfer conveyor and the supporting surface moves below each timber piece in succession and supports it in a downwardly and forwardly inclined position as it is transferred away from the feed conveyor. The transfer conveyor moves through a path such that the foremost edge of each picked-up lumber piece is deposited on a second conveyor which also may be of an endless belt type which travels through a path intersecting the transfer conveyor.
