<p>The heating unit is constructed from two horizontally reciprocating parts having complementary recesses to define several, vertically stacked, cylindrical heating chambers, each with a central heating core extending from a common rear wall plate. The arrangement is movable in axial direction to receive tube ends positioned in aligned and vertically stacked, horizontal position, in front of the heating chambers. Conveyor and transport facilities move tubes laterally in and out of these positions and cause each of them to be heated, in sequence, in each of the chambers.</p> |
