The invention relates to a cold pilger mill for rolling long tubular stock with a stand which moves backwards and forwards, a main drive for the stand, two feed slides, each equipped with a chuck, which are arranged in series in the slide bed in the rolling direction and can be moved in the rolling direction by way of feed spindles that can be connected to the main drive, with at least one gear mechanism for driving the feed spindles and with at least one holding device (mandrel abutment) for the mandrel, which is attached to a mandrel bar. According to the invention, if there are two holding devices (mandrel abutments 11, 12) for the mandrel, at least one can be adjusted in a controlled manner parallel to the rolling direction to compensate for changes in the position in the mandrel relative to the rolling gap. <IMAGE> |
