DEVICE AT THE ENTRANCE AND EXIT OF SHEET METAL COOLING MACHINES

摘要

The arrangement is provided in order to limit or prevent leakages of cooling liquid which always occur under various circumstances at the ends of the machine. The arrangement is provided at the input and output ends of the machine for cooling metal sheets or the like, which is of the type comprising an upper frame and a lower frame. Each frame comprises two lateral walls interconnected by a case which defines an enclosure in which the cooling liquid circulates. The arrangement resides in the fact that there are provided, at each of said ends, on one hand, a sump for collecting the cooling liquid and carried by the lower frame and extending throughout the width of the machine and, on the other hand, a device carried by the upper frame and adapted to project toward the interior of the machine a jet of fluid which is directed in counter-current fashion against the cooling liquid which tends to issue from the machine.
