Machined to match/mate up with the pins or blades that are being used. Grooves can vary in width and depth, and must be precision CNC machined in order to match up precisely with the perforating roll. Grooved rollers can be supplied as metal, urethane covered, silicone covered or rubber covered. Positives to grooved rollers are the fact that the pins are essentially in air, there is nothing to wear the pin. Drawbacks are that thinner materials can deflect off the pin tip and cause variation in hole sizes. One also has to mate the pins or blades up to the grooves precisely in order to prevent damage to the pins or blades. Grooved roller do not release particles, however, only work for low perforation density applications.
