coupling/uncoupling bank machine is usually
set on the belt-sanding line, by the seal
test zone of the bank.
Should the operator check any loss of one
or more components during the water test,
he must draw the bank from the test tank,
put it down on the coupling/uncoupling machine,
uncouple automatically (by a foot control
lever) the bank, replace the damaged radiator
and couple the bank again.
The operator could put the bank again in the
water tank for a new test, for safety reasons.
