Envelope Bag Making Machine

Step 1: Roll Paper Feeding
The initial stage of the operation of the device is paper roll feeding. Begins with a film-unwinding gadget that unwinds the film in the form of rolls into the machine from a feeder role. The unwinded paper is taken straight into the feed chamber. The paper roll is being fed into the machine to produce paper bags.

Step 2: Paper Bag Forming
During this stage, the feeder rolls start to transfer the paper material into the formation stage, where the actual fabrication of the paper bag takes place. The activity mainly involved in this stage is sealing. The paper material passes through the temperature-regulated elements for a specific duration that provides an effective sealing to the film. Sealing time and the quantity of temperature of processing can be adjusted in the machine depending on the quality of the paper material. After the sealing, the materials pass through chiller units to bring down the temperature.

Step 3: Cutting
With the completion of sealing, the materials then pass through the cutters with sharp blades that move upwards and downwards. The cutting step is the core of the manufacturing process because the design of the cutting segment largely determines the type of the machine.

Step 4: Gluing
In the gluing stage, attaching and combining several cut pieces take place. The gluing compartment spreads the glue on the end portions of the paper bags in longitudinal and a transversal manner.

Step 5: End Folding
At this step, the almost ready paper bag passes through a system of rollers which presses the paper bags to make them wholly in a single piece. The end sections of the bags also get folded.

Step 6: Finish
Once the whole process ends, the bags get transferred to the stacker and then to the conveyor. The conveyor transmits the different pieces of paper bags to the ejection point from where one can pick them up.
