Large batch creasing

[CoupdeTete]

Wondering if anyone has information about how large batch manufacturers crease leather that is not just belt strapping but also curved. This can't all be done by hand, can it? Creasing wheel would only work for straight strap and hand creasing is not efficient for large batch.

Probably with a dedicated press

Any kind of curves or shapes isn't going to work with the traditional rotary die creasing machine, where you are creasing both sides at once, but Angeleri in Italy does make a single edge creasing machine that will do any shape you throw at it. Do a search for model RIG Hot Creasing Machine to find North American distributors. The RIG-B is a flat table machine, while the RIG-C is more like a cylinder arm (more common I think). It's the only production method I'm aware of, other than investing in big custom dies and hydraulic presses. If you're not doing many, hand tool creasing would be the alternative.
