The feed mechanism of a bag closer is more conventional that helps to achieve smooth and better looking closures of bags. The parts of a bag closer are also machined to a closed tolerance and are heated to a certain temperature to bring resistance and reduce downtimes in them.

2.What Are the Advantages of a Bag Closer?

Advantages of a Bag Closer

Safety handling

Safety handling

Bag closers are fully equipped with safety measures and shows no tolerance in that factor. The plastic handle is also there for insulation purpose.

Continuous Operation

Continuous Operation

Bag closers are efficient in closing bags with ease that are on the bagging line. The machine takes the bag itself or manually and with comfort closes it depending upon the specification of material.

Quality

Quality

The quality of thread closing achieved using a bag closer is a unique factor of this machine. No manual closing technique can even come closer to a bag closer when it comes to uniqueness and precision.

Soundless Operation

Soundless Operation

Unlike traditional sewing machine, operation of a bag closers produce no sound because of a high grade and wear resistant nylon cam that are capable of reducing noise to a distinct level. The machine has no steel cam which actually is responsible for producing sound.

Adaptability

Adaptability

Bag closers have high adaptability as they can be used in any type of conditions and are also moveable which helps the manufacturer to use it where and when required

Availability of Spares

Availability of Spares

The spare parts of bag closers are easily available in market and are also changed after long time due to their supreme quality material

Non-corrosive Structure

Non-corrosive Structure

Bag closers are highly suitable for production setup’s including places where humidity is present. The non-corrosive structure supports the machine to resist from environmental conditions and increases its life.

Auto Thread Cutter

Auto Thread Cutter

Traditional the cutting of end thread was done manually which directly involves human nature to any accident. A bag closer has an automatic thread cutting blade which cuts the thread with severe protection and in a closed manner.

3.What Are the Applications of a Bag Closer?

Applications of a Bag Closer

Packaging Industry

Packaging Industry

Bag closers are usually functioned by a simple stitched chain. This structure helps them to operate at a high speed level. This is why these bags are most popular in packaging industries where papers, rubber or clothes bags are sealed in an efficient manner. The productivity of a bag closer is that much high that it sews a bag in less than 6 seconds. This makes its application more useful for all of the industries. Bag closers are mostly used in food packaging, where floor or other items are closed. These are also applied in manufacturing industries, where high productivity is to be achieved in less time.

4.What Is the Working Principle of a Bag Closer?

Working Principle of a Bag Closer

Working Principle of a Bag Closer

The working principle of a bag closer is just like an ordinary sewing machine. It just includes high level of automation and integrated systems. The working principle of a bag closer follows following points.

Initially all the external parameters of a bag closer like temperature, needle quality, conveyor speed, thread quantity and nature according to the bad composition and electrical connections are checked with high concern.

When all the parameters are found to be normal then the process of a bag closer machine is said to be start.

In the process, the bags are filled with material at first and then directed towards the bag closer.

Manually or through conveyor system, the bags are inserted in the system through a device guide.This device guide also straights the top edges of bags which make it easy for the machine to sew. The speed of feeding is also set account to the quantity and nature of material.

As the bag is detected on the system the automatic sewing head starts its operation. It allows the thread to travel from in feed needed and as the bags moves forward the sewing process is carried out.

At the end when the bag is completely closed, the excess thread is removed by sharp edged blades and similarly the process is repeated in cycle.
