Abstract
A drawhead for drawing equipment having a plurality of fallers or the like disposed parallel to each other along a closed guideway at a predetermined distance from one another. In such a drawhead it is expected to achieve the transfer of large forces parallel to the guideway in a simple manner, while avoiding all sliding friction. This is achieved by equipping each faller with at least two pivot bearing elements of differing diameters placed axially next to each other in such a way that the pivot bearing elements of adjacent fallers are disposed in such a way that two adjacent pivot bearing elements with smaller diameters adjoin each pivot bearing element with a larger diameter and that two pivot bearing elements having larger diameters adjoin each pivot bearing element with a smaller diameter.
