Title
(EN) WORKING HEAD FOR A PASSEPARTOUT-MACHINE
(FR) TETE DE TRAVAIL D"UNE MACHINE-PASSE-PARTOUT
Abstract
(EN)
A working head for a so called passepartout-machine by means of which rectangular cuttings and/or impressions can be made in a plain material and which is formed with a knife (6) or an impression roller which is mounted in a holder (30) which is connected to a rotatable housing (5) for being lifted and lowered. A pressure roller (7) adapted to be in contact with the plain material is like wise connected to the rotatable housing (5) for being lifted and lowered. The rotatable housing (5) is fixed connected to a central shaft (2) at the upper end of which a Maltese cross (14) is mounted and which by engagement with a cam disc (9) having a pin (10) and provided on a driving shaft (1) for the Maltese cross (14) can be rotated intermittently, so that the central shaft (2) is rotated one fourth of a turn when the driving shaft (1) is rotated a full turn. The Maltese cross (14) has recesses (16) for a movable locking wedge (34) which locks the central shaft (2) after the rotation. The locking wedge (34) is a part of a catch (33) made of several pieces.

Le corps rotatif (5) est fixe a un axe central (2) a l"extremite superieure duquel est montee une croix de Malte (14) et qui, par engagement d"un disque a came (9) ayant un ergot (10) et monte sur un arbre d"entrainement (1) pour la croix de Malte (14) puisse tourner avec intermittence, de sorte que l"arbre central (2) tourne d"un quart de tour lorsque l"arbre d"entrainement (1) effectue un tour complet. La croix de Malte (14) possede des evidements (16) pour une clavette de verrouillage mobile (34) qui verrouille l"arbre central (2) apres la rotation. La clavette de verrouillage (34) fait partie d"un dispositif d"arret (33) fait de plusieurs pieces.
