<p>An apparatus (20, 110) for making mattress and upholstery spring coils. The apparatus (20, 110) has a wire feeding device (69) and a wire guide (52) adapted to support first and second wires (44,46) of different diameters. The wire guide (52) is movable to first and second positions to align the first and second wires (44,46), respectively, with a spring coiling machine (110)positioned adjacent the wire feeding device (69). When the wire guide (52) is in the first position, the spring coiling machine (110) receives the first wire ( 44) of one diameter from the wire feeding device ( 69); and the spring coiling machine ( 110) bends the first wire ( 44) into a spring coil of a desired diameter and pitch and having a first stiffness. When the wire guide (52) is in the second position, the spring coiling machine (110) receives the second wire (46) of another diameter from the wire feeding device (69); and the spring coiling machine (110) bends the second wire ( 46) into a spring coil of the desired diameter and pitch but having a second stiffness.</p> |
