Abstract
Abstract An arrangement for the further treatment of sectional steel stock delivered by a rolling mill includes a coiler unit for coiling the stock emerging from the mill, a cooling conveyor for conveying the coils while cooling them, an uncoiling unit, a section straightening unit for straightening the stock after uncoiling, a cutting unit for cutting the stock into required lengths, a collection station and a collection unit for collecting the straightened, cut lengths of stock at the collection station. Packaging and loading equipment may be used with the collecting devices.

Claim 1
Independent Claim
192 words
An arrangement for processing hot-rolled sectional steel stock delivered by a rolling mill, the arrangement comprising the following units arranged as a continuous processing line, in the order set forth: a Garrett coiler having a rolled stock entry guide for coiling the hot stock into coils as it emerges from the mill, said entry guide comprising inner and outer telescoping members, said outer member being positioned adjacent to said coiler and being retractible therefrom to effect withdrawal from said guide of a straight length of stock extending from the end of said coil, a cooling conveyor for coveying the coils, while cooling them, along the processing line, an uncoiling unit comprising a rotatably mounted uncoiling arbor with means for holding a coil with its coil access horizontal, a section straightening unit for straighening the stock after it has been uncoiled. a parallel cut shear for cutting the stock into required lengths, a device associated with the shear for braking and conveying the cut lengths, a collection station, a collection unit for collecting the straightened, cut lengths of stock at the collection station, and a packaging station located downstream from the collection unit.

Claim 3
Dependent Claim
25 words
The arrangment as claimed in claim 1, wherein there is more than one processing line, and each line is arranged downstream from the Garrett coiler.
Claim 4
Dependent Claim
40 words
The arrangment according to claim 1, wherein a motor is provided to drive the arbor, and the rotational speed of the motor is adapted to be controlled in accordance with the size of the unwound loop of the rolled stock.
Claim 5
Dependent Claim
29 words
The arrangement according to claim 3, further comprising an electrical or optical sensing device for scanning the unwound loop of the rolled stock operatively connected to the uncoiling unit.
Claim 6
Dependent Claim
19 words
The arrangement according to claim 1, wherein an uncoiling arbor is mounted on each side of the uncoiling unit.
Claim 7
Dependent Claim
65 words
The arrangement according to claim 1, wherein the collection unit comprises travelling collecting trolleys adapted to travel in a closed path from the collection station to the packaging station and back to the collection station and wherein the braking device comprises a sloping chute or slat conveyor provided between the conveyor roll table and the collecting trolleys to slow down the flow of rolled stock.
