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.

Dependent claims

In a coiler arrangement for coiling hot metal rolling stock comprising a coiler mandrel rotatably mounted within a housing having a peripheral opening through which rolling stock is guided for coiling around said mandrel,

said arrangement also including a roller table cooperatively disposed relative to said housing and formed of a plurality of table rollers defining a roller way upon which said rolling stock is transported to said coiler via said opening in said housing and guided to said mandrel by means of a pivot flap cooperatively associated with said roller table,
said pivot flap extending from said roller table to the vicinity of said mandrel,
said pivot flap being provided with means for actuating said flap into a position for guiding said rolling stock to said mandrel,
the improvement which comprises:
a pivot flap assembly pivotably mounted on said housing by axle means located adjacent the peripheral opening thereof,
said pivot flap assembly extending across said peripheral opening and having a first flap portion with its free end extending forwardly of said axle means and a second flap portion extending rearwardly thereof,
said flap portions cooperating one with the other for closing off said opening and providing sufficient space to allow for passage of said rolling stock to said mandrel,
and pivot drive means cooperatively associated with said housing for actuating said pivot flap assembly from an open to a closed position and vice versa.
