(57) An apparatus for moulding a staircase includes a plurality of tread and riser mould
part assemblies (14) arranged along the apparatus (10), each tread mould part (24)
of each assembly (14) extending downwardly from a connection (26) with the riser mould
part (25) of the assembly (14), which riser mould part (25) also extends downwardly
at an opposite side of the connection (26), the lengths of each of the tread and riser
mould parts (24, 25) from their respective connections (26) being adjustable, and
the apparatus (10) further including a support structure (16, 17) characterised in
that the tread mould part (24) of a first assembly (14) and the riser mould part (25)
of an adjacent second assembly (14) are connected to a first bogie means (40) which
is movable along the support structure (16, 17) of the apparatus (10), and the riser
mould part (25) of the first assembly (14) and the tread mould part (24) of a third
adjacent assembly (14) are connected to a second bogie means (41) which is movable
along the support structure (16, 17) of the apparatus (10), the lengths of the tread
and riser mould parts (24, 25) of the first assembly (14) and of the riser mould part
(25) of the second assembly and of the tread mould part (24) of the third assembly
(14) being adjustable as the first and second bogie means (40, 41) are moved towards
or away from one another.
