Cantilever Film Slitting Machine
High-Quality Film Conversion with Smooth Web Handling
The Cantilever Film Slitting Machine has been developed to slit wide rolls of flexible film into narrow rolls needed for packaging, printing, lamination, and other converting purposes. Since flexible film can stretch, wander, or become wrinkled in case there is no adequate control over the web tension, the machine ensures that the web moves in a controlled manner during the entire process. The cantilever configuration of the rewinder makes it easy for the operator to reach the finished rolls and to make the roll change operations easier. The machine can be customized depending on the material type and web width.

Slitting Developed for Flexible Film Behaviour
Flexible films require a different handling approach because their behaviour changes with thickness, elasticity, surface characteristics, and roll tension. The machine keeps the web properly supported as it passes through the cutting section.
Accurate positioning of the slitting components allows a parent film roll to be divided into the required widths with neat and consistent edges. Suitable settings can be selected according to the film being processed.
This flexibility makes the machine useful for converters producing different reel sizes from the same or different parent-film specifications.
Smooth Web Travel from Unwind to Finished Reel
Consistent movement of the film is crucial for obtaining a good reel with even wrapping of the film and proper finishing. Flexible thin films are prone to wrinkling, stretching, slack, or uneven edges because of the changes in tension in the course of the process. The machinery controls the operations of unwinding, guiding, slitting, and rewinding of the film.
Web tension and winding parameters can be adjusted depending on the thickness of the film, its properties, roll diameter, and the desired reel dimensions.
Proper guiding of the web is also important for ensuring that the film is in the right position prior to and during the slitting process. The cantilever reel winding makes finished rolls accessible.
Why Flexible Films Need Accurate Slitting Control
Film rolls used for packaging and converting purposes usually require accurate finished width before being taken up for printing, forming of pouches, laminating, etc. Irregular slitting may not only impact material efficiency but also downstream production process.
Proper alignment of the web is required in order to maintain the stability of the cutting line, and control of the winding ensures proper formation of finished rolls. Proper tension setting becomes especially relevant in case of thin and stretchable film substrates.
When the right parameters are set for the right substrate, the equipment will ensure reliable slitting operation.
