ABSTRACT:
An apparatus for assembling innerspring constructions from rows or strings of pocketed coil springs comprises a generally planar support surface with a pressure plate mounted parallel to and above the support surface. The apparatus includes a bonding material applicator for applying bonding material to a first row of pocketed coil springs retained by the pressure plate. A pusher bar assembly is provided for pushing a second row of coil springs into intimate contact with the first row whereupon the two rows become bonded. The pusher bar assembly includes a pusher fixture having two opposed sides, each with differently spaced dividers for receiving rows of springs having differing diameters. The pusher fixture is manually rotatable to employ a desired set of dividers depending on the size of the coils being assembled. The bonding material applicator includes a trigger bar having alternatively readable indicia for synchronizing the application of bonding material depending on the preselected sizes of coils being assembled.
