摘要

The device has first(18) and second(19) interacting feed rollers with at least one of the rollers driven and with the rollers tangentially touching each other on their periphery. A circular heating disc(30) is installed in the first feed roller and has a diameter larger than the diameter of the first roller's periphery. The second feed roller has a circumferential slot(31) in which engages the periphery of the heating disc. The first feed roller consists of two co-axial individual rollers(20,21) mounted on a common shaft(10), and with the heating disc installed co-axially between them.
