Abstract (en)
[origin: CN110730703A] Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs modules, comprising more than two pocketed springs surrounding a central hole, can be automatically loaded onto an assembler; pocketed spring- surrounded openings can be automatically aligned with welding phalanges; and probe/anvil welding pairs can be inserted into modules in different rows of modules, closed around polymer pocket fabric, and activated to weld rows of modules together without glue; without a user manually loading rows of modules onto the assembler.
