Why Do You Need a Frame Type Slitting Machine?

In our past working experiences, the turret rewinding diameter is almost less than 1000mm.

It is a threshold to be more than 1000mm diameters for roll slitting machines in the field.

More than 1000mm, means the more functional problems need to be resolved.

The first problem is that the machine must be larger in size especially since the bigger tall machine frame is not friendly to operational labor.

The second problem is that the motor power must be increased at least two times of the original motor power. A bigger rewinding diameter means a bigger power force for rotating.

The third problem is all the differential friction shaft in the world is mainly applicable to rewinding diameter to 800mm, more than that, the friction ring journey is limited, which means the rewinding would not be tight anymore.

The fourth problem is that the machine frame should be reinforced and strengthened because of the large slitting force that will appear during operation.  And normal roll slitter rewinder machine can’t bear such big heavy mother rolls in high speed running.

The fifth problem is the finished roll unloading.

Mainly the finished slitting rolls with a diameter of 1200mm, it is heavy to unload to the floor. Even with the help of the hoise or the frame rack, it is still adequate.  With our bridge type slitter rewinders, the finished material could be unloaded to the floor easily. To reduce the labor working strength and working hurt risks.

The customer’s requirement is bigger and higher, but the present roll slitting machines can’t meet the customer’s extremity.

As a professional slitter machine manufacturer, One new roll slitter rewinders need to be considered and redesigned now.

Easy Operations

The machine with Shaftless Unwinding Stand, The Big Heavy Mother rolls could be clamped by the unwind arms easily and be lifted. It is with the Max. diameter of 1500mm. The max. loading weight is more than 4000kgs.

It is with an easy unloading rack for the finished rolls, after the finished slit, the paper rolls could be easily unloaded to the floor.

Two rewinding shafts are located on each side of the mainframe, and the rewinding roll closes to the floor, so it is easier for the core positioning and material movement.

High Efficacy

For the new bridge type, the biggest requirement should be high efficiency. Mainly only the big printing press or packaging companies will think about such high-capacity equipment. Just one demand is efficiency.

The roll slitter rewinder designing speed is 500m/min. In order to realize the working speed at 500m/min. All the machining parts and machine frames should be designed and tested. And the machine frame and parts quenching is required.

The infrared auto core positioning devices and auto knife positioning devices are optional. Both of them are our patented technologies, which could help you improve your efficacy.

Patented Finished roll unloading devices. The finished rolls could be pushed to the rack automatically, reducing the roll change times and strengths.

Splicer Table: It helps the operators to join the new material tails. The last material ends and new material tails will be connected on the tables.

Low Cost And Long Service Life

We supply the bridge type slitter rewinders in width from 1600mm to 2800mm. Compared with the normal slitters, the bridge type slitter prices are not cheap, but thinking about its capacity, it is quite economic on each roll working cost.

It is a wider slitter rewinder, so one-day slitting roll quantities should be more than the narrow one. It means dividing daily working costs, one labor can convert more paper rolls at the same working time.

We use stronger machining parts, and famous electric appliances on the machines, it is with less maintenance and has a long working life span.

A higher speed at 500m/min, means more rolls could be slit at working times. To help you create more values.

Meanwhile, the lay-on roller can prolong the material tensions.

Patented Differential Friction Shaft

In order to realize the rewinding diameter of 1200mm, we redesigned the friction shaft structure, the friction journey has been prolonged.

Why do I need to buy the rotary sheeting machine?

If you’re a packaging company, printing company, or printing press, you probably have a lot of paper to convert. You have two options on the paper sheeting machine, one is the guillotine scissor-type sheeting machine, which speeds around 100 cuts per min,

the other one is the rotary sheeting machine, which speeds around 300 cuts per min.

What’s a rotary sheeting machine?

A rotary sheeting machine is a piece of machinery that is used to cut paper rolls into sheets with a pair of rotary cylinder knives.

Mainly there are two types of rotary sheeting machines, one is a simplex rotary sheeter, and the other one is a dual synchronized flying sheeter.

The rotary sheeter has a high capacity of around 10 to 15 tons of paper rolls per day. It is mainly suitable for packaging companies and printing presses.

How rotary sheeting machine works?

The rotary sheeting machine works by unwinding rolls of paper and feeding it through a pair of NIP roller to cut the paper into sheets by a pair of rotary cylinder knives.

There are three different types of rotary sheeting machines: an unwinder with two rolls, an unwinder with four rolls, and an unwinder with six rolls. Each machine can be set up to cut different widths of paper, depending on the type of machine you have.

When you’re using a rotary sheeting machine, it’s important that your blades are sharp. Dull blades can cause uneven cuts and create undesirable lumps in your sheets of paper. This makes them harder to stack later on in the process.

Rotary knives are servo motor-controlled so they will remain consistent when cutting through different materials at high speeds at 300 cuts per min. The transmission belt also helps keep papers running smoothly by transferring power from one part of the system to another without causing any unnecessary friction or slowing down production times significantly at all. then feeds into a stacker which can hold up to 1300mm of material at a time.

Which type of sheeting machine do I need to purchase?

You are right. The type of sheeting machine you need to purchase depends on your productivity and the materials’ thickness. Also, the length of sheets is a factor as well.

If you are looking for a low-cost solution, then consider purchasing a guillotine scissor type sheeting machine. It is a great option for short runs and smaller quantities. However, if you need to run longer sheets or produce more parts in one batch, then a rotary sheeting machine is better suited for that purpose.

If you have any questions or concerns about any of these options please let me know!

If you’re looking to produce large volumes of high-quality sheets quickly, then an automated sheeting machine is likely the best fit for your needs. These machines are capable of producing up to 300 meters per minute and can accommodate materials as thick as 1000gsm. They also have the ability to work with a wide variety of materials and finishes.

The type of sheeting machine that’s right for you will depend on what kind of products you’re making and how many sheets you want to make each day!

What’s the sheeting machine working parameters?

The working parameters of our sheeting machine are as follows:

  1. We supply the sheeting machine width from 600mm to 1700mm. Your material mother rolls decide your machine width
  2. Working speed: 100 cuts/min to 350 cuts/min. The guillotine scissor-type sheeting machine speed around 100 cuts per min, and the rotary sheeting machine speed at 350cuts per min.
