Foam slitting is an important foam cutting technique, which is mainly used to make foam tapes and rolls. Foam slitter can also used for other material production such as adhesive, foil, film and liner etc.. With foam slitting, foam materials can be easily converted into small rolls with custom widths and lengths.

For foam slitting, the two main methods we use are lathe slitting and rewind slitting.

Lathe Slitting

Lathe slitting is easy to operate on foam materials. It is a simple foam fabrication process that a log of foam roll with or without pressure sensitive tape spins on a stationary mandrel at high speed, while a circular blade slices the material into the required width. Papers, foams, plastics, films, foils and many other materials can be cut using a lathe slitter. When actual production, lathe slitting is more suitable for slit small foam tape and foam roll.

Rewind Slitting

Rewind slitting is suitable to work with large foam rolls and thin foam materials. Rewind slitting can slit foam materials with tight tolerance and are able to cut long large foam rolls. The slitting machinery functions by utilizing score, razor, or shear slitting methods. For fabricating foam tapes, we generally use razor cut slitting technique, which employs single razor blades positioned at stationary intervals across the machine. Foam roll material is pulled through the stationary blades, making precise and clean cuts.
