ABSTRACT:
A multi-layer circular wooden frame of the type used as a steering wheel or hand rail for a chair is provided using a machine which includes a cylindrical forming shell rotatably mounted to a support, a plurality of pressing rolls disposed around the forming shell and movable toward and away from the shell, first and second feeding rollers and a reed which are also movable toward and away from the cylindrical shell. An elongate feeder is pivotally mounted so that one end is disposed for movement toward and away from the cylindrical shell and for delivering one end of a flat strip of wooden board into a passageway to be provided between the feeding rollers, pressing rolls, reed and the cylindrical shell. One end of a flat strip of wooden board is delivered between the first feeding roller and the cylindrical shell, the feeding rollers and pressing rolls are moved to a position closely adjacent the cylindrical shell and then the cylindrical shell and pressing rolls are rotated to wrap the flat strip of wooden board around the exterior surface of the cylindrical shell. A second layered strip of wooden board having adhesive applied thereto is then wrapped by the machine components around the outer surface of the first wrapped board.
