Pocket coil spring structure assembling apparatus

A pocket coil spring structure assembling apparatus for producing a pocket coil spring structure for use in upholstery furniture by bonding rows of pocket coil springs to one another, each pocket coil spring including a coil spring accommodated in a tubular pocket made of a nonwoven or fabric material, said apparatus comprising:

• a feeder mechanism for supplying a group of pocket coil springs to a positioning transfer conveyor mechanism for conveying the group of pocket coil springs supplied from said feeder mechanism to a predetermined location;
• a cutter mechanism mounted between said feeder mechanism and said positioning transfer conveyor mechanism for separating a trailing group of pocket coil springs from the group of pocket coil springs by cutting the group of pocket coil springs at a predetermined length to provide a cut group of pocket coil springs;
• a press holding mechanism for holding and lifting the cut group of pocket coil springs on said positioning transfer conveyor mechanism by pressing centers of opposite ends of each pocket coil spring;
• a press holding mechanism carrier mechanism for moving said press holding mechanism in forward, backward, leftward, and rightward directions;
• a spray mechanism including a spray nozzle for applying a spray of an adhesive material to the cut group of pocket coil springs;
• a nozzle carrier mechanism for moving said spray nozzle;
• and
• a controller mechanism for controlling each said mechanism.
