Abstract
An apparatus for manufacturing pocketed coil springs is provided. The apparatus includes a pair of weld heads and an adjustment assembly for moving the heads longitudinally or transversely from each other. The relative position of the weld lines in a fabric passing beneath the heads can accordingly be set with precision. This is accomplished by rotating one of the heads about two axes, one extending through the head and a second axis extending parallel to the first at a selected distance therefrom.
