Abstract
Abstract A continuous rolling mill plant for rod steel and wire having several rolling mill units each consisting of a pair of stands disposed side-by-side with a first stand of each pair being aligned in the direction of rolling, which stands form a finishing train permitting continuous rolling. The second stands of each pair permit repeater rolling. A runout roller table may be arranged below the finishing train in order to discharge the roller material from any stand. Instead of a runout roller, table coiler means may be arranged along and adjacent to the finishing train.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
A continuous rolling mill plant for rod, wire and strip, comprising several rolling mill units each consisting of two rolling mill stands one of which is suitable for finishing rolling, said finishing stands forming at least two aligned, trains, characterized by the following cOmbination of features, viz: a. that all of the rolling mill stands are arranged in sequence for the passage of the material subjected to roll b. that the individual rolling mill stands are driven separately by motors connected to said stands by means of couplings; c. that the finishing stands forming an aligned train consist of stands with horizontal rolls; d. that a repeater transfers the material between the rolling mill stands of the same rolling mill unit; and e. that repeaters transfer material from the aligned train to another train below the rolling mill stands of the aligned train without crossing any couplings.
Claim 2
Dependent Claim

A continuous rolling mill plant for rod, wire and strip, comprising several rolling mill units each consisting of two rolling mill stands one of which is suitable for finishing rolling, said finishing stands forming at least two aligned, trains, characterized by the following cOmbination of features, viz: a. that all of the rolling mill stands are arranged in sequence for the passage of the material subjected to roll b. that the individual rolling mill stands are driven separately by motors connected to said stands by means of couplings; c. that the finishing stands forming an aligned train consist of stands with horizontal rolls; d. that a repeater transfers the material between the rolling mill stands of the same rolling mill unit; and e. that repeaters transfer material from the aligned train to another train below the rolling mill stands of the aligned train without crossing any couplings.
Claim 3
Dependent Claim
171 words
A continuous rolling mill plant for rod, wire and strip, comprising several rolling mill units each consisting of two rolling mill stands, one of which is suitable for finishing rolling, said finishing stands forming at least one aligned train, characterized by the following combination of features, viz,: a. that all of the rolling mill stands are arranged in sequence for the passage of material subjected to rolling; b. that the finishing stands forming an aligned train consist of stands with horizontal rolls; c. that a repeater transfers the material between the rolling mill stands of the same rolling mill unit; d. that repeaters transfer material from the aligned train to another train below the rolling mill stands of the aligned train; and e. that the rolling mill units comprise staggered rolling mill stands separately driven from both ends and that coupling devices connect the two staggered rolling mill stands in such a way that in straight continuous rolling the entire driving power can be transferred to the working rolling mill stands.
