Abstract
A method for manufacturing a curable light-conducting body (21) in a casting method, in particular for the manufacture of light-conducting bodies (21) of a curable concrete material (36, 56), wherein a light-conducting mat (1) is embedded in a curable casting material (36, 56), and a casting mold (27) with a recessed mold cavity (18) open at the top is filled with the not-yet-cured casting material (36, 56), wherein, in a first method step, a plurality of molding punches (32) moveably arranged in the mold cavity (18) of the casting mold (27) are moved to at least the plane of the upper edge (43) of the mold cavity (18), 1. in a second method step, the space between the molding punches (32) in the mold cavity (18) is filled with a curable casting material (36), 2. in a fifth method step, the light-conducting mat (1) to be embedded in the casting material (36, 56) is placed on the end sides (61) of the molding punches (32) raised in the mold cavity (18), 3. and that, in a sixth method step, the light-conducting mat (1) is pressed into the casting material (36, 56) wherein, with the pressing movement of the light-conducting mat (1) into the casting material (36, 56), the molding punch…
