Set the transport belts to the sheet size
whereby the external belts 5 should run
near the sidelays (avoid any touch
agains them). Do not reposition the
inside (internal) belts 4 underneath the
ball rail. Depending on the sheet size
you may use guide rails 11 to avoid any
distortion of the sheets. Ball holders 7
should be fitted to the inner ball rails 6.
Depending on the paper quality and
machine speed you may use either light
or heavy balls. In any case, use balls as
less as possible to save the belts and
the folded products. When the sheet has
reached the sheet stop prevent it from
bouncing back. For this purpose high-
speed wheels 8 are used at the end of
the sheets. The wheels should be
positioned to such an extent that the rear
edge of the sheet is levelled with the one
wheel, and the other wheel is levelled
with the transport belt. These high-speed
wheels also garant a better control of the
sheet at sheet stop during alignment at
high speed production. In addition
thereto, you should also place ball
holders with brushes 3 onto the external
ball rails. These ball holders should be
placed into such a position that the ball
runs in centre of the external transport
belt and the brush is positioned on the
sheets rear edge. The clearance between
the tapes and bars is height adjustable
by means of lever 9 (loosen locking
screw!). Depending on the sheet size
you may also use stop fingers 12 to
prevent any buckling of the sheets 10.
