sealing zone. If there is insufficient pressure, the material may also simply stop moving
and get stuck on the tabletop. Alternatively, with a lack of consistent pressure along the
entire length of the Skidbar Assembly, the substrate can slip and skew which will result in
inaccurate label placement.
Figure 3-8: Tabber Skidbar Assembly side view.
If the spacing between the tabletop surface and the ball bearings is not equal along the
entire length of the skidbar, the Skidbar Assembly must be adjusted. There are four
support blocks (p/n 9101059) with machined oblong cutouts that allow for adjustments to
be made to the position of the Skidbar. By loosening the mounting screws shown in
Figure 3-9 and pushing on one of the Skidbar Brackets (p/n 330302), the level of the
Skidbar Assembly can be set to have an equal gap between the tabletop and the bottom
surface of the Skidbar Assembly. The mounting screws for the brackets should be
tightened once the correct setup is achieved. Double-check for a consistent gap between
the Skidbar Assembly and the tabletop once all the screws have been tightened.
