APPARATUS FOR MAKING ASSEMBLIES OF POCKETED SPRINGS ABSTRACT The subject apparatus assembles strips of pocketed upholstery springs, one strip at a time, into spring cores for mattresses and the like. The connections of each such strip to its predecessor are made between the interpocket webs of the pocket sheeting of the two adjacent strips, preferably at intervals of two springs, and are staggered by one spring from strip to strip. The disclosed and preferred technique for joining the pocket material of the adjacent strips is thermal welding by ultrasonic vibration, but other specific forms of connection are also suggested.
