<p>A spring mattress is described, comprising a plura- lity of strings interconnected side by side, each string comprising a continuous casing material with a plurality of pockets, said pockets being defined by at least one longitudinal connecting line extending parallel to the longitudinal direction of the string and a plurality of transverse connecting lines extending transversely to the longitudinal direction of the string, and coil springs arranged in the pockets of the string. For at least one of the springs, casing material portions arranged at the ends of the spring are moved towards each other, through the spring, and connected to each other. Moreover "the connecting lines are arranged at the side of the springs and, thus, between neighbouring springs. Preferably, the interconnected casing material portions are thus at the ends of the springs essentially free of other connec- tions . Also a method and a device for manufacturing such a mattress are disclosed.</p> |
