Operation Manual
There are several kinds of paper pressing bars (Figure 21-2). Select appropriate paper pressing bar
according to different paper tube width. Make sure that the height of paper pressing bar does not
exceed that of bottom opening rattler.
Releasing time point of bottom opening clamp (Figure 21-4) can be adjusted by the handles (Figure
21-5) on two pieces of screws. It becomes later when turning clockwise while becomes earlier when
turning anticlockwise. The time is adjusted according to the paper bag bottom width. If the time is
too short, the bottom opening will be finished badly; if the time is too long, the bag bottom corner
will be broken due to pulling.
The method for adjusting the position of bottom opening clamp is: loosen the gear nut on
transmission side, and then adjust the bottom opening clamp forwards and backwards until the
clamp nips right on the position of the first pressing line. By doing so, there will be perfect bag
bottom produced. And finally, fasten the gear nut for normal production.
5.4.2.6. Operation of Bottom Former Part
Adjustment of side guiding board: select appropriate side guiding board according to different bag
width. The adjusting principle is that horizontal width should be same as the width of paper bag and
the upper part should cover the underside turned over (Figure 22).
Adjustment of middle guiding bar: the middle guiding bar cannot block the bottom turned over;
otherwise the underside will not be unfolded. If the space is too small, one guiding bar shall be
enough.
