Roll Slitting Machine: Log Slitter and Rewind Slitter

Roll slitting machines are used to cut a wide roll of web material into two or more narrow rolls. Common materials that undergo this process include pressure sensitive adhesive tapes, foams, foils, films, textiles, fabric, vinyl, nonwovens, rubber, felt, fiberglass, graphite, cork and leather. Basic types of roll slitting method mainly consist of log slitting and rewind slitting, which have many difference in respective application fields. Choosing which slitting method should be depending on the material being cut and your specific slitting requirements.

Log Slitter Machinery

In log slitting machine, a roll of material is treated as a “log” and it can be sliced without any unrolling and rewinding process. A large circular blade plunges into the roll and slices it into required width. Nowadays, log slitting machines have a variety of names including baloney slitting machines, baloney slicers, bologna cutters, single knife roll slitters and lathe slitting machines, a computer-controlled lathe slitters can provide rapid and high-volume production.

Log slitter is a kind of lower-cost machine investment, it’s easy to set up and logs can be changed quickly. Single cut is very fast and even one person can handle the whole cutting process, greatly save the labor cost. Log slitting is a ideal solution for cutting various types of materials such as double-sided adhesive tape, self-adhesive tape, foam, rubber, gasket, vinyl, PVC and many other materials.

Rewind Slitter Machinery

Rewind slitting machine has an unwind station for holding the parent roll. Web material is unwound from a parent roll through one or more rollers, and then pass a series of cutting blades, rewound onto empty recovery cores to form desired width rolls. Based on specific requirement, rewind slitters can be equipped with several slitting methods including razor slitting, shear slitting and score slitting.

Rewind slitter can be configured to your individual industrial needs and budget. For example, single and duplex rewind shafts are optional for holding the empty cores to rewind the material. Differential shafts are available to allow tension on the same shaft to balance from one slit roll to the next, it’s very critical when material thickness varies across the web.

Also, rewind slitter mahcines have many advantages over log slitters. First, rewind slitters can make multiple cuts simultaneously and rewind onto variable core sizes, offer the best possible slit edge quality. Second, slitter rewinders can not only cut material into narrower rolls but also can rewind material from one roll to another. Third, slitter rewinder machines have many automatic controls system including responsive tension control, web guiding control, etc. LEAP can manufacture and design all types of roll to roll slitting machines for your bussiness.
