Assembly machine for manufacturing partially foam encased pocketed spring assembly

An assembly machine for manufacturing a partially foam encased pocketed spring assembly, the machine comprising:

• a first station comprising a front assembler, at least one supply source for strings of pocketed springs and at least one front loading tray for loading foam rails into the front assembler, the front assembler comprising a front glue applicator, front infeed belts, and compression belts;
• a second station downstream of the first station, the second station comprising two side assemblers on opposite sides of the front assembler;
• and
• a transport system for transporting intermediate products from the first station to the second station.

An assembly machine for manufacturing a partially foam encased pocketed spring assembly, the machine comprising:

• a front assembler comprising a front pusher assembly, a front glue applicator including a glue head with multiple nozzles which moves along a guide rail to manufacture a core having first and second foam rails;
• a first side assembler on one side of the front assembler, the first side assembler comprising a side pusher assembly, a side glue applicator including a moveable glue head which moves along a first side guide rail;
• a second side assembler on the other side of the front assembler, the second side assembler comprising a second side pusher assembly, a second side glue applicator including a moveable glue head which moves along a second side guide rail;
• at least one front loading tray for loading first and second foam rails into the front assembler;
• at least one supply source for at least one string of pocketed springs to be loaded into the front assembler;
• and
• at least one side loading tray for loading third and fourth foam rails into the side assemblers.
