Abstract
A method and apparatus for assembling box springs for use in bedding applications. The apparatus comprises a base for supporting a frame and a spring unit, a framework with a plurality of tools coupled thereto. Each tool has an associated module adjuster coupled thereto. A vertical drive mechanism provides relative movement between the tools and the base where the tools may be disposed between a first vertical position and a second vertical position. A horizontal drive mechanism provides relative horizontal movement between the tools and the base. Each tool is configured to secure a respective module of a row of the spring unit to a corresponding target location on the frame when disposed in the second vertical position and each module adjuster is configured to align a respective module with a corresponding fastening location when the tool is disposed in the second vertical position.
