Abstract: A bending table upon which lengths of plastics material rendered flexible by heating, may be set to determine a desired curvature thereof, particularly for producing arched UPVC window and door frames, the table including an unslotted ferro-magnetic top (1) and a plurality of bobbins (3) each mounted at the end of a radially extending arm (6,7) the arms being mounted upon independently rotatable spindle members (4) such that the angles subtended by each adjacent arms (6,7) is adjustable and wherein the spindles (4) are themselves may be positioned selectively along a locating strip (16) fixed to the table top. Further arms (17) are adjustable along the strip (16) and extend transversely across the table top to support one or more fences (18). The table enables an arched profile (32) having, if required, straight sections, to be produced to any desired shape, and the magnetically attractive bobbins (3) retain the positions of the arms but can be readily adjusted to suit any desired profile.
