FIELD: technological processes.
SUBSTANCE: invention is intended for increase of strip material rolling efficiency, in particular metal strip, during which strip of one roll is unwound in unwinding reel, is inserted into reversible rolling mill and is rolled, afterwards it is wound in roll on reeler, at that metal strip prior to obtainment of preset thickness is reversibly displaced between unwinding reeler and reeler, and in every stage it is compressed in reversible rolling mill. Higher efficiency of process is provided by the fact that prior to the last pass strip accumulator is activated, end of one roll strip is welded to the beginning of the following roll strip, and the first roll strip is accumulated in strip accumulator for provision of welding realisation. Device (versions) for method realisation has appropriate equipment, in which unwinding reeler during reversible passes is accumulator for strip.
EFFECT: higher efficiency of process.
