Paper Roll Material of Roll Fed Paper Bag Making Machine

Paper Roll Material of Roll Fed Paper Bag Making Machine

The roll fed paper bag making machine is a fully automatic paper bag making machine which uses plain or printed paper roll as material.

In some instances, it is also referred to as roll feed paper bag making machine or rolling feed paper bag making machine.

Here is the work flow of MTED roll fed paper bag making machine: paper roll feeding, tube forming, tube cutting, bottom increasing, bottom gluing, bottom closing and final bag collection.

Layout of RZJD-350J Roll Fed Paper Bag Making Machine With Printing

A significant paper roll on a hydraulic shaft unwinds to make a paper web. The paper web is then processed further to create paper bags.

The diameter and width of the paper roll depend on the amount of production and paper bag size, respectively.

Roll Fed Paper Bag Making Machine

Roll-Fed Paper Bag Making Machine

You can use variable paper rolls according to the type of paper bag you want to manufacture. It can be white/brown kraft paper roll, card paper roll, or parchment paper roll.

MTED’s roll-fed paper bag making machines are known for the production of V-bottom and block-bottom paper bags.

You can also manufacture printed, with handles, and with plastic windows paper bags. MTED’s highly qualified engineers are working on designing sheet-fed paper bag making machines with the increasing market demand.

Let’s see how is a sheet-fed paper bag making machine different from a roll-fed paper bag making machine?

2. What Is the Difference Between Roll-Fed and Sheet-Fed Paper Bag Making Machine?

Paper Input

The main difference between the two machines is the way you put the paper in the machine. In a roll-fed paper bag making machine, the uncut paper web passes through all the printing, handle making, and plastic window-making procedures.

The paper is cut after the formation of a tube. Only the bottom construction and sealing are done after the cutting.

On the other hand, in sheet-fed paper bag making machines, you put pre-cut sheets into the machine. The sheets are cut according to the paper bag size.

Tube forming, bottom folding, and gluing procedures take place on these sheets.

Gusset Formation

The side gusset forming in roll-fed and sheet-fed paper bag making machines is different. In a roll-fed machine, the gusset and paper tube forms simultaneously.

In a sheet-fed paper bag making machine, the sheets are folded into a paper cylinder. After side sealing, side gussets are formed.

Gusset Formation in Sheet-Fed Paper Bag Making Machine

Production Speed

In a roll-fed paper bag making machine, you can make up to 220 square bottom paper bags per minute. On the contrary, sheet-fed paper bag making machines produce 80 pieces per minute.

The production speed of a fully automatic roll-fed machine is three times faster than a sheet-fed.

You can cut the paper bag in straight cut or serrated cut.

Bottom Forming Unit

In this unit, the paper bag bottom is open, glued, and sealed. The bottom rollers help to open the paper bag bottom. The glue pasting unit automatically applies cold glue.

The level sensors installed in this unit control the amount of glue applied to prevent wastage.

In the end, the bottom is folded and compressed to stick correctly.

Automatic Counting and Accumulator Delivery

You can set the amount of paper bags in one set on the HMI. The machine will automatically count the paper bags and will pause for a while between two sets.

The final step is the paper bag accumulation on the delivery table. A conveyor belt controlled by a servo motor keeps moving to make space for the next paper bag.

19.  Is the Roll-Fed Paper Bag Making Machine Fully-Automatic?

Yes, it is a fully automatic paper bag making machine.

ServoTech Technology

So you must calculate the size before you go to buy a paper roll. Get a paper roll according to the bag’s size you want to manufacture for your client.

Type of Paper Needed

The second factor under consideration is the type of paper your client needs. You must select the paper roll type according to your client’s requirements.

For example, for a grocery store, kraft paper or recycled paper is the best option. At the same time, for making bakery or cookie bags, you might need parchment paper rolls.

Paper Roll Diameter (inner and outer diameter)

The inner and maximum outer paper roll diameter depends on your paper bag making machine design.

The paper roll outer diameter of MTED’s:

  • Square bottom paper bag making machines vary between 1200 – 1500mm
  • Flat and satchel paper bag making machines range from 1000 – 1100mm

The inner paper roll diameter of the block bottom and V-bottom paper bag making machine is 76mm.

It would be best if you buy paper rolls according to your paper bag machine’s specifications. Otherwise, the paper roll you purchase may not fit into your paper bag making machine.

Moreover, the paper roll’s width determines the paper bag size you want to manufacture. And the paperweight and the total number of bag production determine the paper roll weight.

Consider the Client’s Order

While buying the paper rolls, you must know what your client wants.

Whether it is a heavy-duty paper bag, laminated paper bag, gift paper bag, or grocery paper bag?

Bring an appropriate paper roll according to the requirements.
