Production of Single and Double Butted Spokes

Georg Haas – Amba Aachener Maschinenbau GmbH (Amba)

The third generation of Amba’s All-in-One reducing machines further improves the straightness of single and double-butted spokes—as used, for example, in electric and cargo bikes. The new machines can produce up to 40 spokes per minute.

In the new DD 350-III machine generation, the rotary wire straightener has been re-arranged and is now positioned directly ahead of the cutter, behind the reducing section and the wire feeding unit. In this way, Amba avoids transversal forces and can act on the form-rolled wire during the feeding motion.
