Abstract
An automated process and apparatus for the production of innerspring mattresses having an innerspring situated between top and bottom frame members. A microprocessor controlled apparatus forms the frame members and arranges them for transportation to a clamping table. A first frame member is fed to the clamping table. An innerspring is then fed to the clamping table where it is clamped to the first frame member around the periphery thereof, thereby forming a first combination. The first combination is then removed from the clamping table and a second frame member is fed to the clamping table. The first combination is then turned over and fed back to the clamping table where it is then clamped to the second frame member, thereby forming a completed innerspring mattress. During this process, the frame members are produced and then fed in one direction, the innerspring is fed from another direction, and removal takes place in still another direction along a T-shaped assembly line, resulting in fast, synchronous production.
