摘要

The machine has a sachet closing device formed by a crushing pulley (6) and a marking pulley (5). The crushing pulley is placed in a support relative to the marking pulley. The marking pulley comprises circular protuberances which extend radially on external periphery of the marking pulley with respect to rotational axis. A sachet is placed between the pullies for being sealed by the support among the crushing pulley and the protuberances. Diameter of the crushing pulley is greater than the diameter of the marking pulley.
