CONVERTIBLE MOULD

摘要

: The present invention relates to a convertible mould for moulding an object having a surface with first principal lines which extend in first parallel planes and second principal lines which extend in second parallel planes intersecting the first planes. The mould is comprised of a frame, a plurality of rows each having a plurality of head holders mounted on the frame, each row extending in one of said first planes and a head supported by each head holder. Primary slats are provided having longitudinal dimensions which are substantially greater than their lateral dimensions and secondary slats interlaced with the primary slats and fixed thereon. Each head includes a unit for supporting the primary slats with the longitudinal dimensions thereof extending along the first principal lines. The support unit is pivotable about an axis parallel to the first principal line to allow support of a principal slat in a twisted condition that accommodates the configuration of an adjacent secondary slat thereby allowing the primary and secondary slats to locally conform to the surface.
