US 2001/0032359 A1 · Method and machine for the manufacture of metallic frames for inner spring mattresses

Abstract

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.

Method for the manufacture of metallic frames for inner spring mattresses of round wire or flat wire of any cross section and material subject to plastic bending, which consists of the following stages:

straightening, production of an open frame of a length equal to the circumference of the frame under production, cut-off of the round wire or flat wire with the formation of suitable incisions at the ends of the said round wire or flat wire simultaneously with the cut-off or prior or following it, production of suitable elliptical or circle, connection of the two ends with a connective plate or a small tube or by welding or with glue and a suitable connective plate or a small tube and finally bending of the angles of the frame.

Machine for the manufacture of metallic frames made of round wire or flat wire (1) which is characterized by the feeding and straightening (2) mechanism of the round wire or flat wire (), the length measuring instrument (3) of the fed round wire or flat wire (1), the length measuring instrument (3) of the fed round wire or flat wire (1), the cutter (4) which cuts and at the same time shapes the ends of the round wire or flat wire suitably (1), a guide (5) which consists of two parts, one fixed and one moving freely around a pin (17), a rotation mechanism (8) with a jaw (7) for the production of the suitable open elliptical or circular frame, a connective mechanism (6) fed by a connective plate or a small tube (14), an arm (13) for the transportation of the closed frame from the connective mechanism (6) to the suitably arranged bending unit (9), where such bending unit is capable of feeding and bending the closed elliptical or circular frame.
