Abstract (en)
[origin: WO9325756A1] In the manufacture of switch-point sleeper blocks of varying lengths and having a varying number of rail attachment devices provided in varying positions therealong, there is used a number of matrices (1) which are placed in a long form bed. The matrices (1) include holes in the region of promontories (10a) and the matrix dishes (3) are inserted in the holes and fastened to the matrices (1). When concrete is poured into the form bed and allowed to harden, concrete sleeper blocks which exhibit promontories (10a) of the said kind are obtained. The invention relates to a matrix provided with a matrix dish (3) and to a matrix array which includes a number of such matrices of varying lengths and with different positions for the matrix dishes (3).
