Abstract
A single capstan drum is used to pull alternatingly e.g. tubing through dies and coiling it on the periphery of the drum. The tubing to be drawn is taken from different stores, and while the tubing from one store is drawn, the other die and tubing of another store is prepared and inserted into that die, so that upon change-over the drum has to be halted merely briefly to fasten the end of the prepared tubing to the drum's periphery. The drawn tubing which was coiled dropped off the drum as soon as its end had left the respective die.
