Felt Covered Rolls

Felt covered rollers can be used for both hot and cold perforating applications, and are an inexpensive solution as a backup anvil roller.
Positives of felt technology is that felt rollers have great chemical resistance properties, excellent abrasion resistance, and its decent temperature resistance. Drawbacks are that the surface of the roller is not accurate enough for fine perforating. Note that covered rollers can particulate, so it is recommended that the user have particulate detection systems downstream of the rollers.
