What type of products can RollRazor cut?
RollRazor was originally designed to cut standard-weight papers. However, RollRazor has successfully cut Bible weight, tissue, towel, non-woven paper products, SBS, liner, corrugated grades, and others. Trials are currently underway for cutting film, foil, carbon fiber and plastics. Because the RollRazor cutting process eliminates heat, the materials it can cut are almost limitless.
How does RollRazor cut a roll?
RollRazor uses a large diameter blade to cut from the outer diameter to the core in one pass. There is NO unwinding and rewinding the web like a slitter/rewinder. The tooth geometry on RollRazor’s saw blade allows it to cut a wide range of products without generating any heat.

Can RollRazor make multiple cuts on a single roll?
Yes! An operator programs RollRazor to make a certain number of cuts on a roll, including the width of each slice. RollRazor then starts on one end of the roll, and performs the first cut, then indexes to the next location and makes the second cut. It repeats the process until all cuts are made.

How loud is RollRazor?
Tests conducted while cutting groundwood paper rolls showed an average of 84 dB at the operators console, which is comparable to the use of a milling machine (85 dB) or a garbage disposal (80 dB). This noise level is present only during the cutting process, which is approximately 3 minutes per cut.
