Abstract
A coiler-furnace combination comprises a horizontal coiler, a strip guide which comprises two pressure rollers for forcing the strip against the coil and two part-cylindrical guide segments, one of which precedes the other in the winding sense and adjoins a strip transfer bridge for transferring the strip to and from the coiler, and a strip lifter. To simplify the structure, the two guide segments are secured to arms which pivoted on pivots disposed outside the heat-shielding hood and parallel to the mandrel. The strip lifter is constituted by the delivery edge of that guide segment which succeeds the other in the coiling sense. The strip transfer bridge consists of a roller conveyor and at its end facing the mandrel has a pressure roller for forcing the strip against the coil.
Claims5
In a coiler-furnace combination comprising
- a heat-shielding hood,
- a horizontal coiler mandrel disposed in said hood and rotatable in a predetermined sense to coil strip on said mandrel and in the opposite sense to uncoil said strip from said mandrel,
- strip-guiding means for guiding said strip around said mandrel as it is coiled on and uncoiled from said mandrel, which strip-guiding means comprise pressure rollers for forcing said strip against said mandrel and two part-cylindrical guide segments which are disposed on opposite sides of and movable toward and away from said mandrel, one of said guide segments preceding the other in said predetermined direction, said other guide segment having a delivery edge for delivering said strip as it is coiled up on said mandrel,
- actuating means for urging each of said guide segments toward said mandrel generally in a predetermined direction,
- means for heating strip coiled on said mandrel,
- a strip transfer bridge, which is pivoted below said mandrel and adapted to transfer said strip from and to said mandrel and is adjoined by said one guide segment, and
- a pivoted strip lifter which is disposed above said bridge and adapted to lift the outer end of strip coiled on said mandrel from the remainder of said coiled strip,
- the improvement residing in that
- each of said guide segments is secured to a pivoted arm, which extends transversely to said predetermined direction and is mounted outside said hood on a pivot having an axis that is parallel to the axis of said mandrel,
- said delivery edge constitutes said strip lifter, and
- separate drive means are provided for imparting a pivotal movement to said bridge independently of said actuating means.
