Abstract

675,531. Moulding building blocks. VICTORIN, J. G. A., and REINHOLD, K. KLAESSON-. Dec. 1, 1949 [Dec. 1, 1948], No. 30897/49. Class 87(ii) [Also in Group X] A process for moulding concrete building blocks consisting of a number of parallel lamellae (see Group X) is characterized in that cores arranged between the lamellae are drawn out in groups, after moulding, in at least three different directions. The mould, consisting of an open frame 2 resting on a separate bottom 1, has slots 3 in two opposite sides to accomodate cores 4 shown partly withdrawn. When in the moulding position the inner edges of the cores 4 abut the sides of a set of vertically disposed cores 7 which are arranged in staggered positions in the mould as shown in Fig. 2. The cores 7 are supported by the mould sides and by a beam 8. After moulding they are raised vertically into a stationary compressing plunger which is slotted to accomodate them.
