A capstan that starts marking the wire, a pulley with bright, torn patches, a batch coming off the line with longitudinal scores always in the same place: these are the classic symptoms of galling, a form of damage caused by direct contact...

In wire drawing the wire runs continuously over the mechanical components of the line: capstans, cones, rings, pulleys and wire guide rollers. What happens at that contact point — on a scale of a few micrometres — determines friction, generated...

On a wire drawing line every capstan, pulley or cone works in constant contact with the wire. That contact is continuous and under load, and over time it wears down the surface precisely where stress concentrates: the pulling band, the part of...

In the metal wire drawing industry, there are applications where operating conditions are particularly demanding and require dedicated technical solutions. One of these is the drawing of ribbed wire for reinforced concrete, where the mechanical...
