The feeding unit is designed for efficiency and ease of use. The roll paper is secured onto an air expanding shaft, then fed into the machine using a swing arm with an advanced hydraulic lifting system. This unit is equipped with an alarm system that activates when paper replenishment is necessary. Furthermore, it incorporates an automatic web guide and uniform tension control, ensuring the paper is fed into the machine with optimal alignment and smoothness. Simplifying the roll change process, a button control allows for easy and quick replacement, enhancing overall productivity that sounds an alarm when paper needs replenishing.

The handle making unit is designed for effective and accurate handle making. It starts by feeding two rolls of patch paper and one roll of paper rope into the machine. The paper rope is then glued to the patch paper, using both water and hot melt adhesives for a strong bond. After the gluing process, the combined material is compressed to ensure the handles are firmly attached. The final step involves cutting the handles to the correct size and transferring them to the handle patching unit, preparing them for attachment to the bags.

The handle pasting unit is designed to paste handles to paper bags with precision and efficiency. After cutting the handles that were made previously, they are accurately placed at the designated position on the paper bag. The unit then applies a water-based adhesive to bond the handle to the bag. Once attached, the handles are firmly pressed onto the bag surface, ensuring a secure hold. This process is completed before the bag enters the pre-creasing stage, preparing it for the final shaping in the forming unit.

This unit starts by cutting the paper into individual pieces based on the pre-set tube length parameters. Following the cutting, the unit applies glue to the top edge of each paper piece. The final step involves neatly folding over the top edge, ensuring a clean and secure fold. This process is critical for preparing the paper for the next stages of bag assembly.

In the bag forming unit, the process begins with applying glue along the sides of the paper. This is followed by precise folding to create a paper tube. These tubes are then transferred to the drum mechanism, where they are opened into a four-cornered bottom shape, assisted by a vacuum suction system for accuracy. The final steps involve applying glue to the bottom, sealing it, and shaping the bag into a perfect square form.

The bag collecting unit plays a crucial role in the final stages of paper bag production. This unit takes the formed bags, compresses them for consistency, and then outputs the finished bags. An integrated counting system displays the number of bags processed, providing valuable information for quality control and production management.
