Abstract
Abstract A movable casting mould for use in a production line for such articles as prefabricated concrete slabs is adapted to run on a track which may comprise parallel rails. The mould is assembled from a plurality of individual movable elements each comprising a panel which forms a side wall of an individual mould, and running gear which preferably includes rotatable ball units in contact with said track to allow movement in direction both parallel and perpendicular to the planes of the panel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
An element for use in a movable multiple casting mould said element comprising a panel for defining a wall of said mould and running gear for movably supporting said panel, said panel being arranged to extend in a generally vertical plane above the running gear when said running gear is in contact with a generally horizontal surface, said running gear being adapted to allow movement of the element in direction both normal and parallel to the plane of said panel, and said element further including at least two support members on which an edge of said panel is mounted, wherein said support members are in the form of bar members which project beyond the planes defined by the vertical faces of the panel and which are arranged at an oblique angle with respect to said planes, and each of said support members being provided with part of said running gear.
Claim 2
Dependent Claim
150 words
An element for use in a movable multiple casting mould said element comprising a panel for defining a wall of said mould and running gear for movably supporting said panel, said panel being arranged to extend in a generally vertical plane above the running gear when said running gear is in contact with a generally horizontal surface, said running gear being adapted to allow movement of the element in direction both normal and parallel to the plane of said panel, and said element further including at least two support members on which an edge of said panel is mounted, wherein said support members are in the form of bar members which project beyond the planes defined by the vertical faces of the panel and which are arranged at an oblique angle with respect to said planes, and each of said support members being provided with part of said running gear.
Claim 3
Dependent Claim
19 words
An element according to claim 1, whereIn the bar members are arranged so that their longitudinal axes are parallel.
Claim 4
Dependent Claim
36 words
An element according to claim 1, wherein at least two bar members are arranged at equal and opposite angles to the normal to said planes so that the produced longitudinal axes of said bar members intersect.
Claim 5
Dependent Claim
16 words
An element according to claim 1, further including rotatable ball running units as said running gear.
Claim 6
Dependent Claim
26 words
An element according to claim 1 wherein the panel is mounted so that it can be tilted about an axis parallel to and adjacent said edge.
Claim 7
Dependent Claim
33 words
A movable multiple casting mould comprising a plurality of elements according to claim 1 releasably assembled by clamping means into a movable unit, the panels of said elements being arranged in parallel relation.
Claim 8
Dependent Claim
58 words
A movable multiple casting mould according to claim 6, further including a framing member interposed between adjacent elements, said framing member being clamped into engagement with adjacent panel faces by said clamping means and being generally U-shaped in cross section so that said member forms a bottom and two minor sides of a unit of said multiple mould.
Claim 9
Dependent Claim
16 words
A movable multiple casting mould according to claim 6 wherein said clamping means is hydraulically operated.
