Abstract
An apparatus is provided which makes a border wire having a rectangular cross-section. The apparatus is adapted to receive a roll of wire having a circular cross-section, straighten the wire and change the cross-section of the wire to rectangular. The reconfigured wire is then accumulated, passed through another straightener, cut to size and then bent into a rectangular configuration. Opposed ends of the piece of wire having a rectangular cross-section are welded together to complete the border wire. The apparatus has an ejector which removes the completed border wire from the apparatus.
Claims19
A method of making a border wire for a bedding product, the method comprising:
- providing a source of wire having a circular cross-section;
- passing the wire having a circular cross-section through a metal forming machine to create a wire having a rectangular cross-section;
- accumulating the wire having a rectangular cross-section in an accumulator;
- passing the wire having a rectangular cross-section through a three-axis straightener;
- measuring a predetermined length of wire having a rectangular cross-section;
- cutting the wire having a rectangular cross-section to a predetermined length to obtain a piece of wire having a rectangular cross-section;
- bending the piece of wire having a rectangular cross-section using four bending assemblies into a rectangular configuration;
- butt welding opposed ends of the piece of wire having a rectangular cross-section to create a rectangular border wire.
