Title (EN) A CUTTING DEVICE
(FR) DISPOSITIF DE COUPAGE
Abstract:
(EN) A cutting device comprises a carrier means (5), in which two substantially circular disks (1, 2) are provided, which disks have cutting edges and are mounted to be freely rotatable. At least one of said disks has at least one axially through recess (7) along its circumference, which recess extends radially inwards from the circumference. Said disks comprise portions which cover each other in an axial projection of the disks, and the planes comprising the cutting edges of the respective disks extend at a slight mutual distance. Said recesses are adapted to the diameter of the object (6) to be severed, the edge of the recess also being designed to be a cutting edge. An edge portion of the recess of one of the disks extends substantially in parallel with an adjacent edge portion of the other disk, when the object to be severed is introduced into said recess, so that mutual rotation of disks (1, 2) as a consequence of the fact that object (6) is urged in a direction towards the connecting line between said disks will cause both disks to exert substantially oppositely directed shear forces against the object (6).
(FR) Un dispositif de coupage comprend des moyens porteurs (5) dotés de deux disques sensiblement circulaires (1, 2), lesdits disques, qui comportent des tranchants, étant montés de manière rotative. Au moins un desdits disques comprend au moins un logement le traversant axialement (7) le long de sa circonférence, ledit logement s'étendant radialement vers l'intérieur depuis ladite circonférence. Les disques comprennent des parties qui se recouvrent dans une projection axiale desdits disques, les plans qui forment les tranchants des disques respectifs s'étendant à une distance légèrement mutuelle. Les logements sont adaptés au diamètre de l'objet (6) devant être coupé, le bord du logement étant conçu également en tant que tranchant. Une partie du bord du logement disposé dans un des disques s'étend sensiblement parallèle à une partie du bord de l'autre disque adjacente, lorsque l'objet devant être coupé est introduit dans ledit logement. L'objet (6) est poussé vers la ligne de raccordement entre lesdits disques, ce qui entraîne une rotation mutuelle des disques (1, 2) et les deux disques appliquent audit objet (6) des efforts de cisaillement sensiblement opposés.
