APPARATUS FOR HEAT-TREATING A CONTINUOUSLY MOVING METAL WIRE

摘要

The device for heat-treating the wire (18), which is looped with several windings around a drum (6) in the heat treatment zone, has at least one tensioning roller (10) which is associated with the drum (6) and is looped by each wire winding in series with the drum and whose axis is displaceable in parallel and/or pivotable with respect to the axis of the drum (6) against the action of a limited tensioning force applied by a tension device (14, 15, 16, 17), whereby breaking of the wire in the case of an operational interruption and stopping of the drum are avoided and, in the case of the tensioning roller axis being pivotable, tight contact of the windings on the drum and on the tensioning roller is additionally ensured (Figure 1). ……
