Method and machine for the manufacture of metallic frames for inner spring mattresses

摘要

A round wire or flat wire promoted and having been straightened by the feeding straightening mechanism is measured by the length measuring instrument and shaped into a suitable elliptical or circular shape by a rotating arm with a jaw, is then cut to the desired length by a cutter, its ends being suitably shaped by a shaper prior to or following it and are connected by a connective mechanism with a suitable connective plate in a manner that the material of the means of connection penetrates into the suitable incisions formed by the cutter or the shaper. In the sequel, an arm transports the frame for bending into a suitably arranged bending unit where the frame takes its final shape.
