Each station is provided with a single mechanism for power adjustment of all head pairs. The mechanism is movable the entire length of the shafts and is selectively engageable and disengageable with each head pair. After the head pairs are in desired longitudinal positions along the shafts, the adjusting mechanism is parked at one end of the shafts outboard of the web path or working area of the station.
