Production of Single and Double Butted Spokes
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 Amba’ new DD 350-III machine generation, the rotary wire straightener has been re-arranged, and it is now positioned directly ahead of the cutter and located behind the reducing section and the wire feeding unit. With this configuration, Amba avoids that transversal forces can act upon the form-rolled wire during the feeding motion. And thus, the wire retains exactly the high level of straightness with which it leaves the straightener.
