Title (EN) PROCESS AND DEVICE FOR CLOSING THE END OF A CATERPILLAR-SHAPED WRINKLED TUBE SECTION,PARTICULARLY OF SYNTHETIC GUT FOR PRODUCING SAUSAGES
(FR) PROCEDE ET DISPOSITIF POUR FERMER L"EXTREMITE D"UN TRONCON DE BOUDIN PLISSE EN FORME DE CHENILLE, NOTAMMENT DE BOYAU SYNTHETIQUE POUR LA FABRICATION DE SAUCISSES
Abstract: front page image
(EN)To close the end of a caterpillarshaped wrinkled tube section (122), particularly of synthetic gut for producing sausages, a few rotations are imparted to a tool pressed against the end of the section so as to bring that end to engage, without torsion, the periphery of the tool. The tool is then slightly withdrawn and it is further rotated so as to form, from the tube connected to the tool, a coreless rove (126), moving inside the caterpillar. Finally the tool is completely withdrawn from the tube. With such method, the danger of braking the tube disappears and the number of torsions may be substantially increased when a complete filling is desired. To separate the tube from the tool, a brief reversed rotation direction is sufficient. The tool is appropriately comprised of a rotary and axially moving mandrel (124), with a periphery appropriate to friction driving preferably of square shape, which may be a portion of the axially displacable shaft (86), which may be actuated by means of an axially moving drive (100) and axially translated by a piston (92) against a spring (102). Such arrangement allows a complete mechanization of the torsionning process.
(FR)Pour fermer l"extremite d"un troncon de boudin plisse en forme de chenille (122), notamment de boyau synthetique pour la fabrication de saucisses, on fait subir quelques rotations a un outil presse contre l"extremite du troncon de maniere a amener cette extremite a se fixer sans torsion a la peripherie de l"outil. On retire ensuite legerement l"outil et on lui imprime une nouvelle rotation afin de former, a partir du boudin raccorde a l"outil, une meche (126) sans noyau, mobile a l"interieur de la chenille. Enfin on retire completement l"outil du boudin, Avec ce procede le danger d"une rupture du boudin disparait et le nombre de torsions peut etre sensiblement augmente lorsqu"on desire obtenir une etancheite totale. Pour la separation du boudin de l"outil, une breve inversion du sens de rotation suffit. L"outil est constitue de maniere appropriee par un mandrin (124) rotatif et mobile axialement, avec une peripherie favorable a un entrainement par friction, de preference de forme carree, qui peut etre une partie d"un axe (86) deplacable axialement, pouvant etre actionne au moyen d"un entraineur (100) mobile axialement et translate axialement par un piston (92) a l"encontre d"un ressort (102). Une telle dispositif permet d"obtenir une mecanisation complete du processus de torsion.
