Abstract
Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs, preferably arranged into modules of more than two pocketed springs surrounding a central hole, are welded together when paired probes and anvils press layers of pocketed spring fabric from the rows of pocketed springs together and a welding pulse of current is transmitted through wires on the probes to heat the wire it is pressed against the fabric. Non-stick material interposed between the wires and the fabric prevents melted fabric from sticking to the wires.
