Usage:
The SLD model is particularly suitable for processing webs with a width of more than 2000 mm. Therefore, it is used in a large number of paper mills, paper converting plants, and roll slitting service providers. In addition, many paper product manufacturers such as food wrapper,paper bags, paper cups, paper tubes, etc. also need to use SLD type slitter rewinder. It is widely used in the field of printing and paper product packaging.

Slitting knives: The slitting knives shaft diameter is 100mm. It is enough strong to hold knives and avoid trembling during machine running. Therefore, the cutting accuracy is very high.One end of the shaft is fixed, and the other end is rotatable. This design makes it very easy to replace the slitting knives.The slitting knife is made of high-speed alloy steel. It has the characteristics of high precision and durability.

Constant tension system:The system consists of aluminum rollers and two sets of cylinders. One set of cylinders is equipped with damping sensors. The air cylinder outputs the corresponding air pressure according to the signal of the damper, so as to adjust the position of the aluminum roller. With such a system, the tension of the paper during transport can be kept constant at all times.


Why you need a set SLD-series paper jumbo roll slitter rewinder machine?

Answer: If you are director and owner of the paper converting companies,printing house or paper roll processing factories,you must want to process more large width jumbo roll. The SLD series paper slitter rewinder machine is an ideal equipment to reach the requirement. The gantry structure ensure that machine can stable slit and rewind more than 2000mm width paper jumbo rolls. The maximum width machine is 3000mm in the series machine.

My paper jumbo rolls have various inner diameter core. Can SLD-series machine pick up different inner diameter core jumbo rolls ?

Answer: Yes, the unwinding stand has multi size air chucks for fitting various inner diameter cores,such as 3 inch,6 inch,12 inch or other customize size. Our machine chucks adopt the mechanical structure to fix the paper jumbo rolls during machine running.

What are the advantages of the unwinding stand in the SLD series paper slitting rewinding machine?
Answer:Our unwinding stand itself weighs more than 4 tons. When it is loaded with jumbo paper rolls and speed reach maximum, it can still remain very stable. The arms in the unwinding stand are controlled by hydraulic cylinders,which have enough power to pick up 3000kg weight paper rolls and 1600mm diameter rolls.

Do you have the paper web automatic threading system as option?
Answer: Yes,we have the automatic system for easily threading paper web in our machine. Please contact with our sales to get details.

How the machine control the unwinding tension?
Answer:About of the unwinding tension control,we have three options,magnetic powder brake,pneumatic brake,and servo motors. The motors control tension system is the most sensitive and stable. But there also has advantages of controlling tension by the brake. If you want to knwo which type tension controlling system is better for your material,please contact with our sales teams.

Does the model machine have banana roller?
Answer: The banana roller used to spread paper web to eliminate the wrinkles in the paper. Normally,we will install the rollers for customer who mainly convert thin paper rolls. It is very important to tell your material characteristics and details requirements to our sales.

How to adjust the knives to get various slitting width?

Answer: The SLD series machine slitting unit include upper knife and bottom knife. Both of them are freely moved in the knife shafts. Don’t need take the knife shafts out of machine,operators can easily to install and uninstall slitting knives into the shafts. Because the upper and bottom knife shaft can open their end to offer a gap for installing knives.

Depend on machine width

Case-1:Paper Cups And Paper Bowls And Paper Lid Manufacturing
The model paper slitting rewinding machines widely used in paper disposable containers manufacturers factory. The paper cups,paper bowls forming machine need feed bottom reels to make these products. The machine can well cut jumbo paper rolls into narrow width rolls(maximum diameter can be 1000mm). Paper lid processing also need feeding specific width roll feeding into the forming machine.

Case-2:Paper Bags Manufacturing
Paper bags normal adopt the kraft paper or coated grease proof paper. Our slitting rewinding machine can cut these types paper stock roll into customize width paper rolls,which will feed into paper bags forming machine. But there still many paper bags manufacturer use sheet-feeding paper bags forming machine for some types paper bags. In these manufacturer factory,the paper slitting rewinding machine use to convert after printing paper rolls.

Case-3:Paper Tube & Paper Can
Paper tube is an indispensable tool in the paper product industry. The machine that produces paper tube also needs to input small paper rolls of different widths. These inputting small paper rolls width depend on the how much diameter paper tube you want to make. Therefore, we must cut the paper jumbo roll into small rolls of different widths to meet the paper tube production requirements. Making paper can processing are similar with the paper tube manufacturing.
