A method and apparatus are provided for automatic and hands-free threading of an elastomeric mix into a calender set of rolls comprising one or more pairs of rolls that have a nip between them. A wedge is provided with a tip that is positioned downstream from the nip and at a predetermined distance from the nip. As the rolls of the nip are rotated, the tip of the edge removes all, or a desired portion of, the elastomeric mix from a first roll of the nip so as to transfer the elastomeric mix to a second roll of the nip. The tip of the wedge may be placed into contact with the first roll. The wedge may also have an arcuate surface, shaped e.g., like the outer surface of the first roll, and positioned a predetermined distance from the outer surface of the first roll.
