international projects, beyond the spring industry, and has increased production capacities even in the difficult pandemic years. A second production hall has provided more space for further development and growth. WIM CNC fully automatic lathe coiling machinery for hot or cold coiling is one of Fortuna’s key products, and the company continues to integrate new ideas and solutions into this product line. At wire 2022, Fortuna Federn will present the latest products from its machinery lines, including COM and WIM CNC spring coilers, GRM CNC spring end grinders, BEM CNC wire bending tables, LDT CNC double torsion production machinery, and spring loopers. automation 11 A50 Cold rolling machine maker Fuhr’s portfolio covers equipment from payoffs and rolling stands to in-line measuring systems and take-ups. Its specific strength is customised turnkey machinery built from standardised modules. Fuhr’s cold rolling machines cover a wide range, with cross sections between 0.1 and 1,000mm 2 . Materials are ferrous, non ferrous and precious metals such as low carbon, high-carbon and stainless steels; copper and aluminium, and their alloys; and gold, silver and titanium. One of the company’s specialities is the rolling mill for complex shaped wires. Narrow strips from 2 to 30mm width and 0.1 to 1.5mm thickness are another important field. Traditionally, there are two methods to produce narrow metal strips. In the first method, cold-rolled strip coils in typical widths between 500 and 2,000mm are fed into longitudinal slitting lines. The slitter uses two sets of sharp rotary blades where the width of the blades equals the width of the strips. At the slitting line’s exit, the single strips are wound to tape-style coils, and the length of each coil is identical to the length of the initial wide-strip coil. The precision of slitted strip is good, but the shearing process creates burrs, and trimming processes are required to smooth the edges or create defined edge forms. In the second method, hot-rolled rod or drawn wires are the feedstock for the rolling process.

This approach allows the company to react and adapt its products to customer needs. It takes feedback from customers on where new solutions can be implemented on existing machines, and makes future products more reliable, safe and user friendly. The company also has extended cooperation with major European suppliers of servo technology.

Fortuna Federn says that being a mid size company keeps the internal decision chain short, allowing it to react quickly to clients’ needs. Its team is available to customers for all their issues, with easy, up-to-date communications where pre diagnostics can be made online, directly to the machine through a secure VPN connection. Through internal restructuring in the fields of machinery safety and machine and software design, Fortuna has gained the interest of companies in the automotive industry. With the COM CNC line it delivers custom-made solutions for the mass production of most types of spring used in the industry, using high-tensile silicon chrome OT wire in diameters up to 23mm. With 47 years’ experience in the industry, Fortuna has been involved in many
