Semi Drum Type Paper Slitting Machine
Accurate Paper Slitting with Controlled Reel Formation
This Semi Drum Type Paper Slitting Machine is manufactured for the process of changing the wide rolls of paper into narrower rolls of papers needed in packaging, printing, wrapping, and other paper converting processes. Handling of paper during its slitting operation requires to be done with care, because otherwise there could be chances of damage such as tearing of paper edges, paper wrinkles, irregular winding of rolls, and dust particles. This machine controls the movement of paper through the cutting stage, thus ensuring proper alignment of the paper while making cuts as per the required widths. Its semi drum type paper winding arrangement ensures appropriate support during the paper winding process.

Clean Cutting for Different Paper Grades
Characteristics of papers can vary significantly based on GSM, coating, stiffness, moisture content, and surface treatment. While an arrangement of cutters that works well for light paper will not yield the same outcome when used for heavy or stiff paper.
It is possible to set up the slitting arrangement depending on the type of paper being processed as well as the desired final width. The smooth movement of the paper ensures a straight slit while good knife conditions ensure neat cutting without any tearing of the paper.
This allows converters to produce different paper types in the required reel size.
Semi-Drum Winding for Uniform Paper Reels
Paper reels should be wound at a proper tightness level so that they would stay stable during transportation and future processing. Winding at an improper level may result in deformation either because of low tension of the paper or high pressure of winding.
The semidrum technique ensures balanced support to each wound reel as it becomes larger. Good winding conditions will help to ensure uniform hardness of the paper, even edges, and consistent winding pattern of the reel.
Parameters of winding can be varied depending on the weight of the paper per square meter, reel width, and its final diameter. It will help to obtain well-made rolls for printing, bag manufacturing, coating, lamination, and wrapping.
Why Paper Slitting Requires Material-Specific Settings
Paper may not always be able to be converted with a static machine setting. Light papers, Kraft papers, coated papers, and heavy packaging papers will react differently during the unwind, cut, and rewind stages.
Tension is important to help flatten the paper without exerting too much pulling, and guiding keeps the paper in the right path before it comes into contact with the blades. Setting the correct cutting conditions will also help improve edge quality and prevent wastage of paper.
Setting the machine by considering the GSM of the paper, parent roll, slitting width, and final reel requirement can help converters obtain better results.
