Abstract
The invention relates to a method for changing sets of top rolls, lateral rolls, and a bottom roll, and mounted in chocks of a welding stand of a continuously operating longitudinal tube welding machine. The inventive method enables the rolls to be changed faster, using less appliances. Said method comprises the following steps: the top rolls are lifted; a dismantling/transport means is placed beneath the top rolls; the top rolls are lowered onto the dismantling/transport means and deposited on the same; and, once the top rolls have been removed, the dismantling/transport means is laterally withdrawn.
