Figure 4. Schematic Diagram of Unfolded Paper Bag
5.1.2.3. Loading and Unloading of Material Reel
a) When load the new material reel at the first time, please check the relative position of the reel
core on the air shaft, so as to ensure that paper bags can be produced in the middle of the
machine after loading material reel.
b) Release the air in the air shaft completely by pressing and holding the Air Releasing Button.
c) Put the air shaft through the reel core and adjust the reel core to the most suitable relative
position on the air shaft, meanwhile mark this position on the air shaft. (This mark is used for
quick positioning while reloading next time.)
d) Use the air gun to inject air into the air shaft until the convex keys on the air shaft expand
against the reel core tightly and the reel is fixed on the air shaft.

Opening Locking Device: lift the locking handle (Figure 5-1), and separate the locking buckle
(Figure 5-2) and the pressing bar (Figure 5-3); then lower the pressing bar so that the air shaft
(Figure 5-4) can move away from the groove of the supporting board.
Closing Locking Device: move the air shaft from the groove of the loading arm to the working
position and lift the pressing bar; then lift the locking handle to make the locking buckle buckle into
the groove of the pressing bar, and finally depress the locking handle.
Note:
a) When the locking device is closed, if there is a gap between the pressing bar and the air shaft or
the locking handle can not be depressed, we can adjust the nut on the locking buckle to solve

these problems.
b) If the air pressure is too low in the air shaft, maybe the convex keys on the air shaft can not
expand tightly against the air shaft.
c) It is forbidden to adjust the air pressure in the air shaft in course of normal operations.
d) If the diameter of the reel core is larger than the maximum diameter of the expanded air shaft,
we can use other suitable paper pipes to fill the gap.

5.2.2. Operation of Side Gluing Component
This machine adopts traditional glue transfer method for side gluing (Figure 6). Glue transfer pulley
dips into the side glue plate (Figure 6-6). The surplus glue is scrapped by side glue scrapper (Figure
6-7), then the remaining glue is transferred onto gluing pulley (Figure 6-1) and then transferred onto
raw paper. The driving operation is made by driving gear for side gluing (Figure 6-8).
The separation and reunion between gluing pulley (Figure 6-1) and raw paper are controlled by
clutch cylinder (Figure 6-5).
The gluing position of gluing pulley (Figure 6-1) on raw paper can be adjusted by adjusting hand
wheel (Figure 6-4).
Note:
a) Avoid overfilling glue into side glue plate; the height of glue level should not exceed 2/3 of the
height of glue plate.
b) It is necessary to wash the side gluing components in case of getting off work or out of service
for long time. First dismantle glue transfer pulley and side glue scrapper to wash; then wash
gluing pulley on the machine; finally dismantle side glue plate to pour out the remainder glue,
wash and properly place it for next usage.

1. Air Source Pressure Gauge: for indicating air source pressure.
2. Pressure Adjusting Knob: for adjusting the pressure of air source.
3. Side Gluing Mode Selection Knob: used to select a mode for side gluing (manually or
automatically).
In manual operation mode, clutch cylinder acts to separate the gluing pulley and raw paper so
that glue cannot be applied onto raw paper. This mode is mainly used for adjusting machine.
In automatic operation mode, clutch cylinder acts together with main machine. When main
machine starts up, clutch cylinder acts to make the gluing pulley close to raw paper and glue
can be applied onto raw paper; when main machine stops, clutch cylinder acts to separate
gluing pulley from raw paper, so that glue cannot be applied onto raw paper. This mode is
mainly used for normal operation of the machine.
The conversion between these two modes can be made at any time.
5.3. Main Structure and Operation of Tube Forming Component
In this tube forming component, when the material passes through tube forming frame and forming
moulds, the material can be formed into paper tube and side tucking discs on both sides will nip the
side face into paper tube, so that the process of tube forming is finished.
5.3.1. Main Structure of Tube Forming Component
Tube forming component is constituted by tube forming machine frame (Figure 8-1), forming
mould component (Figure 8-8), side tucking disc component (Figure 8-7) and paper pressing pulley
