How does a roll-feeding square bottom paper bag work?

Working of Square Bottom Paper Bag making Machine

Nova’s machines are built in such a way that they support roll feeding paper systems.

The machine offers different sizes and dimensions to meet the different requirements of the clients 

Before moving to the working, let’s get a little briefing on the machine parts.

 

  • Automatic Tension Control Unit

This unit helps to reduce the web tension of the paper. If there will be less web tension, there will be fewer chances of paper breakage. 

  • Safety Cover

Every machine must have a safety cover unit to ensure the safety of the workers. That’s why Nova fits its square bottom paper bag machine with a safety barrier so that no harm comes your way.

  • HMI control unit

It is the latest technology system introduced in the Nova machines. With the help of this touch control system, you can set the quantity, quality, and size of your square bottom paper bags. 

  • Glue pasting unit

In this unit, the bottom of the paper bags is joined together by using hot and cold glues. Attachment of handles

The handle pasting unit pastes the prior cut handles onto the paper bags. The handle can either be flat or twisted.

  • Unwinding unit

The paper starts unwinding and moves to the cutting unit.

  • Automatic Cutting

Here, the un-winded paper is cut according to our bag choice. With the help of the EPC system, you can choose any length, width, and diameter of the paper.  

  • Collection and counting panel

In this area, all the paper bags are collected and counted without any manual aid. Thus, it saves time and labor costs. 

With all the extraordinary equipment, our machines beat our competitors. 

 

Working 

First, you adjust the size, quantity, and dimensions of the square bottom paper bag on the PLC control touch system.

Our machines work efficiently and have a high production rate. The square bottom paper bag machines manufactured at Nova can make up to 220  paper bags within a minute. 

The inner core and outer core diameters are 76 and 1300 mm respectively.  you can also change this according to your preference

The machine has a power break which operates due to the electronic and magnetic system. This brake keeps the tension of the paper roll in control. 

Having control of web tension is necessary because it helps to reduce the wear and tear in the paper. The EPC system from Italy allows for automatic web alignment, which saves both paper and time.

It has a single feeding frame and an automatic glue system. After loading the paper roll on the shaft, it starts unwinding and the cutters cut the papers into the required shape.

Handle pasting unit makes handles of your required choice. In the next step, the paper and handles are mounted on the pasting unit. Here the handles are pasted with the paper bags through the system of glues. 

The bottoms of the papers are also glued to form the block shape. In the case of printing, the paper is printed prior to the handle pasting. 

After this process, the paper bags are shifted to the assembling unit. Here the square bottom paper bags are counted and accumulated. 

The automatic system of the Nova machines helps reduce manual work.

The machines are monitored continuously with the help of the EPC system to identify any hindrance in the process of paper bag manufacturing.

Nova’s high-quality machinery provides a wide range of perks. Although, you can use paper rolls and paper sheets to make box bottom bags with box bottom paper bag making machine. But keep in mind that the process of working for both techniques is different.

Before going to that, let’s understand the sheet-feeding mechanism.

Sheet-fed mechanism

Sheet feeding machines can work manually and automatically depending upon their features. 

You can use paper sheets of different sizes in sheet-fed machines. 

In the automatic sheet-fed square bottom paper bag machine, the shaft automatically takes the paper sheets. However, in a manual system, you need to place the sheets by yourself.

After pasting the sides of the paper bags together, the bottom structure is complete.

These devices are typically used to produce small-format paper items such as brochures, Business cards which are used to promote a company, and Flyers

Let’s go through its advantages over sheet-feeding paper bag making machine.

  • In the case of sheet-fed machines, to cut the paper sheets in the desired size, you need additional cutters. Whereas, in the case of roll-fed square bottom paper bag machine, cutters are already installed in the machine for efficient working. 
  • Roll-fed machines take up less space than sheet-fed machines in terms of storage.
  • The working process of sheet-fed paper bag making machine is slower. However, the roll feeding machine has high speed. 
  • The raw material for making paper bags on both machines is mostly kraft paper.
  • Roll-feeding machines are more well-known for their versatility and built-in features than sheet-feeding machines.
Can a square bottom paper bag machine make plastic windows in paper bags?

square bottom paper bag machine make plastic windows

Nova ensures that its personnel and equipment are up to date. As paper bags with plastic panes are becoming increasingly popular, Nova also provides solutions for making plastic windows. 

Nova has invented square bottom paper bag production machines that create plastic windows in the paper bags for this purpose.

These windows are in the form of strip and die-cut plastic windows. 

  • Strip plastic windows 

For making strip windows, you don’t have to cut the paper.  Plastic film is glued all the way around the front panel of the brown paper bag.

Strip plastic window paper bags are widely seen in bakeries. 

Hot temperature-controlled machines are used to connect the plastic film. A specified temperature is applied to the plastic window so that it adheres to the paper.

  • Die-cut plastic windows 

To make a die-cut plastic window, Nova inserts special die-cutters into the square bottom paper bag machine. These cutters are available in a range of sizes and shapes.

The cutter cuts the desired shape from the paper before forming the tube. The plastic film is glued to the paper web using an automatic adhesive process.

The plastic film works as an inside liner and provides a see-through window in the square bottom paper bag.

Successful engineers at Nova make the paper bag packaging machines that allow you to attach the handles with the paper bags. 

Nova provides a fantastic way to connect handles to square-bottomed paper bags.

The square bottom paper bags have two adhesive systems: cold glue and hot glue.

The sides of block bottom paper bags are sealed with a cold glue method.

With the help of a level sensor, the cold glue is automatically administered to the paper from an enclosed high-pressure storage tank.

However, we use hot glue to attach the handles to the paper bags.

What types of handles does Nova’s flat bottom paper bag making machine make?

Nova’s paper bag making machine makes three different types of handles.

  • Flat handles 
  • Twisted handles 
  • D-cut handles 

Flat handles have flat ropes. They are not twisted or folded by any means. These are mostly used in the retail and food industries.

Twisted handles have handle-loops that are twisted and used in fashionable paper bags. They add style to the square bottom paper bags.

D-cut handles are widely used in grocery stores for fruits and vegetables. These handles are not in the form of ropes, rather a D-shaped cavity is created on the paper tubes.
