Abstract (en)
[origin: EP0225093A1] A molding device includes a multi-sided contractible inner form 1 and outer forms 2 that can be connected detachably to the inner form. The inner form has, at each side, a wedge-shaped spacer formwork board 4, on which are mounted a power means 42 and a linkage mechanism, disposed between and connected detachably to left and right component formwork boards 11c. The wedge-shaped spacer boards 4 in all sides of the inner form 1 can be pulled inward by individual power means 42 through individual linkage mechanisms to leave space for the left and right component formwork boards to approach one another at all sides to contract the entire inner form.
