Slitting and rewinding machine is an important equipment, it is usually used for slitting paper, plastic film and other raw materials before and after printing. The raw material manufacturers must complete this process to meet the width requirements of customers and other packaging manufacturers. In order to adapt to automatic bag-making process, using slitting and rewinding machine to cut the fixed width printed composite film into finished film roll. With the improvement of flexible packaging automation, consumer-goods manufacturers focus on reducing inefficiencies and pollution in the intermediate links, some manufacturers are gradually changing the technological process and replacing manual packaging with more automated automatic packaging lines.
Slitting and rewinding machine is an important equipment in paper processing industry, which is used almost every day by paper enterprises. It will affect the production process and the manufacturer will lose some money if there is a break down. Generally speaking, the slitting and rewinding machine will often appears some tricky problems if you do not pay attention to the daily maintenance.
The paper spreader does not roll correctly. This situation mostly is caused by the inapplicability of the paper core. In this case, replace the paper core that meets the required inner diameter. In addition, in the rewinding process, the use of rewinding pressure rollers can also avoid uneven slitting and rewinding.
Slitting coiling makes material wrinkling. This is mainly caused by incorrect winding tension. Adjust the proper winding tension of paper slitting machine. The reel is used for rewinding, the paper roll slitter rewinder machine is overpressured before entering the rolling core.
The meter is not accurate. You can solve this problem by making the meter wheel and both wheels contact the feed roller at the same time.
Check the thickness of the brake friction plate of the slitting and rewinding machine made by paper roll slitter rewinder suppliers, you have to replace it when there is serious abrasion.
Check whether the linear guide rails of slitting and rewinding machine are clean, clean it when it is necessary.
Check whether the belt of paper roll slitter rewinder machine maintains proper tension.
Check whether there is air leakage in the air duct of slitting and rewinding machine and whether the air filter is clean. Clean the filter element at least once a month.
Check the surface of all rubber covered roll of slitting and rewinding machine, do not touch the slitting knife to prevent from damaging the surface. Remember to use 1 liter of cleaning solution (warm water with soap or a low surface tension solvent) to wipe the roller gently with a flannelless cloth every week.
Check the filter screen of rewinder paper machine exhaust fan. Please replace it in time if there is too much dirt and stain attached or it is not clean.
When the roller is dirty, it can be cleaned with spinning cloth dipped in industrial alcohol, however it should be noted that some old parts of the slitting and rewinding machine can not be wiped with alcohol so as to avoid the rust.
A slitter rewinder machine is an industrial converting system designed to slit wide rolls of material into narrower rolls while rewinding them with precise tension control. It is widely used for paper, film, foil, labels, nonwovens, and flexible packaging materials. Modern slitter rewinders improve roll quality, production efficiency, and material utilization, making them essential equipment in roll-to-roll manufacturing.
A slitting machine is used to convert large master rolls into smaller rolls with specific widths required for downstream production or end-use applications. Industries such as packaging, printing, electronics, medical, and battery manufacturing rely on slitting machines to achieve accurate dimensions, consistent edge quality, and higher production efficiency. The right machine setup can significantly reduce waste and improve product quality.
Cutting generally refers to separating materials into sheets, parts, or individual pieces, while slitting is a continuous process that divides a roll of material into narrower rolls. Slitting is commonly performed on web materials such as film, paper, foil, and laminates using rotary knives, razor blades, or shear systems. For high-volume roll processing, slitting offers greater speed, precision, and productivity than conventional cutting methods.
When selecting a slitter rewinder machine supplier, consider factors such as industry experience, machine customization capabilities, technical support, spare parts availability, and installation services. A reliable supplier should provide solutions tailored to your material type, roll dimensions, production speed, and quality requirements.
