ABSTRACT:
In a coiler arrangement having a housing and a mandrel penetrating the housing, rolling stock to be wound on and off the mandrel is conveyable from a roller table guiding the rolling stock through an opening of the housing to the mandrel by a pivot flap extending from the roller table to the vicinity of the mandrel and movable by a pivot drive. In order to be able to close the opening of the housing almost entirely during the coiling procedure, the pivot mounting of the pivot flap is realized on the periphery of the housing at a distance from the roller table, i.e., at a distance from the roller way formed by the table rollers. The pivot flap, with its free end, is pivotable into the roller way and, vice versa, is pivotable away from the roller way by closing the housing. At least one flap part is provided to extend the pivot flap in the direction opposite to its free end. The end of the flap part facing away from the pivot axis is pivotable from the region of the mandrel to the housing and vice versa.
