Abstract
A production method for an elongated semi-finished product. A continuously fed wire is rolled by a rotating roller. Along its circumference, the roller has a first segment with a roller profile that rolls a profile into first sections of the wire, and also has a second segment without a roller profile that is rotated contact-free relative to the wire. During the rolling of the profile, the speed of the roller is adjusted in such a way that the speed of the roller profile is the same as the speed of the wire. During the contact-free rotation, the speed of the roller is adjusted in such a way that a length of the wire corresponding to a prescribed length of the second section passes the roller contact-free. A semi-finished product having the first section and having the second section is cut off of the shaped wire.
