Abstract: A method and device for stuffing meat materials into sausages closed by stapling. The processed meat materials, before their introduction into an endless sleeve having a first closed extremity and further narrowing of the stuffed material at regular intervals by spaced staples to produce a line of stuffed elements, are previously subjected to a cutting step at regular intervals of the continuous flow of meat material to be stuffed into the sleeve, making the cuts coincide with posterior zones of narrowing. The device for implementing the process includes a stuffing zone with continuous flow of meat materials, from a stuffing machine through an outlet tube introduced into the sleeve, having a first closed extremity, and includes between the outlet tube of the stuffing machine and the stuffing zone, a guillotine assembly intended to cut transversally the meat material.
