With this sturdy overseaming machine insoles are sewn to uppers. In relation to the conventional lasting method, the Strobel-method saves quite a lot of material. With this machine leather or textiles up to a thickness of 7 mm can be sewn. Thereby the gathering device helps to sew in fullness of the upper. Optional equipment (different feed and front cups) enables the machine to manufacture children shoes or very delicate material. Even kits for string-lasting (with strings up to 1,7 mm or up to 2,5 mm diameter) or for California-type shoes are offered.
