ABSTRACT:
An adjustable radius wood laminate bending and gluing fixture for forming curved wood workpieces from laminate stacks by compressing the laminate stacks between two flexible bands which are drawn against adjustably positionable stanchions which define the desired curve by their position in radial slots on a stanchion supporting bed. Tension is applied to bands in order to draw them against the stanchions by cables which pass from the bands over laterally positionable cranes using hydraulic cylinders. Hydraulic cylinders are also used to reposition the cranes in the course of modifying the fixture set-up in order to produce workpieces having a different size or shape. A ruler affixed to the bed center point may be rotated about that center in order quickly and conveniently to establish stanchion position for production of workpieces having a semi-circular form.
