Experiencing dropped stitches or thread breakage while closing bags is a very common problem that obstructs the rate of production. While there is a vast range of bag packaging options these days, few alternatives are as affordable and reliable as a sewn bag closure.
The bag closing machine is a portable and heavy-duty sewing tool suitable for closing any pre-made open-mouth bags. This bag closer machine closes all types of bags available such as woven polypropylene or unwoven polypropylene, paper (single two-wall or multi-wall), net, and cotton bags filled with anything.
Types Of Bag Closing Machine & Their Working
Usually, the bag closing machine comes in two variants:
1. Single Thread
2. Double Thread
Single Needle-Single Thread Bag Closing Machine
A single-thread single needle bag closing sewing machine is the most demanding sewing machine, This machine is compatible with all types of paper, textile, and poly bags made from HDPE/PP.
This sewing machine is simple to operate, even for inexperienced operators. The reinforced feeding mechanism consists of a wide presser foot and a bigger throat plate than the traditional single thread machines which helps produce smoother, even, and good-looking plain and folded top closures.
This bag closing machine is wear-resistant, hence having lower repair costs. This machine is reliable even under the most adverse operating conditions.
Double Needle-Double Thread Bag Closing Machine
A double-needle, double-thread bag closing machine is strong in construction and assures a reliable performance requiring minimum maintenance for a longer period.
This machine has the same reinforced feed mechanism similar to the single-thread sewing machine. A double thread bag-closing machine is perfect for bag closing applications where a two-thread and a much safer and secured closure is required.
This machine is more versatile in its applications and as dependable as a stationary bag closer. This machine is tougher, faster, and packed with more power for an increased output rate and reliability.
The automatic variant of both types of machines starts and stops automatically by either a micro-switch or photoelectric switch. The start button is activated by feeding the bag into the machine. Similarly, the machine is stopped after the bag passes through, and simultaneously the thread is cut automatically by a built-in air-cylinder-operated type cutter.
The machine has a continuous motion feeding. The needle rotates in epicyclical motions as the bag passes through the closing head. The feeding rollers are power-based and accurately feed the bag to avoid any harm to the bags which can sometimes be caused by a feed dog.
Some Important Features Of Bag Closing Machine
Below are some benefits that allow bag closing machines to function in the toughest environment for all industries with a reliable performance:
1. The bag closer provides trouble-free continuous operation.
2. The machine has a quiet operation. It comes equipped with a high-quality, wear and tear-resistant nylon cam that produces minimum noise compared to the noise experienced in machines with steel cams during operation.

4. The machine has a non-corrosive surface which makes it compatible with damp and humid conditions.
5. This machine has a powerful lubrication system. It consists of an oil pump and a reservoir. The oil pump directs the lubricant to all the main moving parts of the sewing machine
6. It has an enclosed motor which is dust resistant. A high-power sealed motor ensures uninterrupted operation of the machine and improves work efficiency. (1500-1800 rpm). It increases the production rate with less effort.
7. An automatic thread cutter is provided to protect the cutting blades that break off the thread after the bag is closed.
8. A timing belt of 15mm helps the machine to function without much effort under a heavy workload.
9. The bag closing machine is flexible to work with. The stationary or suspended use can be achieved effortlessly from this machine without the loss of useful portable features.
10. The machine comes with a presser foot lifter and thread cone cover.
11. The machine can be attached to conveyor stands, spring balancers, shoulder belts
Applications
The bag closer machine can work in a variety of industries and has the vastest area of applications.
1. The agriculture industry has to deal with bags having seeds, beans, and fertilizers. This is one of the widest areas where the bag closing machine finds its application.
2. Food industry for packing coffee, wheat, rice.
3. Animal feeding materials.
4. The machine is used to close sacks for inorganic fertilizers such as rock phosphate and urea.
