In an apparatus for manufacturing springs, a frame body has guide rails on which a pair of movable bodies are mounted to be movable. Each of the movable bodies has rotatable holding rollers between which a wire which is to be processed is held, and each body also has a shaping roller for bending the end of the wire in a coil. Arranged between the shaping roller and the holding rollers are a guide member for defining the supply passage for the wire, and a pitch rod for determining the pitch of the coil formed. When the holding rollers are rotated, while holding the wire, the movable bodies are moved toward each other by the pulling force exerted to the wire, and the wire is supplied from between the paired holding rollers to the shaping roller through the guide member. The pitch rod is reciprocated as the movable bodies run, and as one turn of the wire coil strikes against the pitch rod, making it possible to form spiral springs at both ends of the wire.

Apparatus for manufacturing spring units

In an apparatus for manufacturing a spring unit, a pair of movable bodies are slidably mounted on a guide rail which is extended on a frame structure. A pair of rollers are provided on the respective movable bodies and a grip mechanism is arranged on the frame. The ends of a single wire are held between the pairs of rollers and the intermediate portion of the wire is gripped by a grip mechanism so that the single wire is stretched between the movable bodies. A swing arm is axially and swingably supported on each of the movable bodies and a forming roller is pivotably fixed to the respective swing arms. A guide is arranged between the forming rollers and the rollers and a pitch rod is arranged between the guide and the forming roller. When the swing arm is swung, the forming roller is abutted against the end of the wire and when the pair of movable bodies approach each other, the wire is extracted from the holding rollers and is abutted against the forming roller, thereby spirally forming the end of the wire with the forming roller.

Apparatus for manufacturing spring unit

A cushion unit with an opening section is placed atop a bed frame. Rails are laid under the bed frame, and a truck reciprocated by a drive mechanism is placed on the rails for traveling. The truck carries movable units on which an elastic pad and a urinal are mounted. Each of the units is provided with guide rollers for vertical movement within guide members extending under the bed frame, facing the opening section. The guide rollers associated with the elastic pad or the urinal engage with the guide members according to the direction of travel of the truck, thus raising either the elastic pad or the urinal from the truck to fit the same into the opening section of the bed cushion unit.
