The foundation for RÖSLE's second field of operation, began back in 1903. The first kitchen equipment was added to the production line and came into the sales programme, beginning as enamel ware. After the death of Karl Theodor Rösle in 1907, his sons Karl and Georg took over the firm as Gebrüder RÖSLE KG, expanding the line of roofing equipment with such great success, that during 1918 and 1919, a larger factory could be built outside the narrow confines of the city centre.
