CA 2464401

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.

L'invention concerne une machine (20, 110) à enrouler les ressorts de matelas et de rembourrage pour meubles, qui comprend une unité d'alimentation en fils (69) et un guide de fils (52) soutenant des premier et second fils (44, 46) de diamètres différents. Le guide de fils (52) est mobile entre des première et seconde positions, ce qui permet d'aligner les premier et second fils (44, 46), respectivement, avec une machine à enrouler les ressorts (110) adjacente à l'unité d'alimentation en fils (69). Lorsque le guide de fils (52) occupe la première position, la machine à enrouler les ressorts (110) reçoit le premier fil ( 44) de diamètre donné depuis ladite unité d'alimentation ( 69); ensuite, la machine à enrouler les ressorts (110) enroule le premier fil ( 44) en une spire de ressort, selon le diamètre et l'espacement requis, et suivant une première rigidité. Lorsque le guide de fils (52) occupe la seconde position, la machine à enrouler les ressorts (110) reçoit le second fil (46) de diamètre différent depuis l'unité d'alimentation (69); ensuite, la machine à enrouler les ressorts (110) enroule le second fil ( 46) en une spire de ressort, selon le diamètre et l'espacement requis, mais suivant une seconde rigidité.
