ABSTRACT:
For closing gaps between blocks of a moving edge dam prior to its travelling downstream into the entrance of a moving mold defined between upper and lower revolving casting belts moving downstream from the mold entrance to its exit, the moving edge dam is initially elevated into a crest, as shown in FIGS. 12 and 14. This crest is above a plane generally defined by the lower casting belt travelling downstream. Then, a guide roller positioned above thrusts downwardly upon the moving edge dam bending it convex downwardly as shown at "B" in FIG. 14 for causing its dam blocks to press against each other for sliding them along their high strength endless flexibile carrying member, thereby closing gaps between the blocks entering the mold entrance for sealing the entrance against outward leakage of molten metal between blocks. The downward convex bending also produces desired downward pressure of the moving edge dam against the lower casting belt, thereby enhacing sealing action between moving edge dam and lower belt. The downward thrust of this roller is sensed for indicating the amount of tension in the endless flexible carrying member of the moving edge dam. Back-breaker apparatus in rolling contact with a moving edge dam during its sagging return travel from mold exit to mold entrance has remotely controllable lift means for controllably raising or lowering the sagging edge dam for respectivley increasing or decreasing tension of the endless flexible carrying member.
