Title (EN) CAN OPENERS
(FR) OUVRE-BOITES
Abstract:
(EN) In a can opener having a traction wheel (18) for driving the end seam (26) of a can past the opener, and a cutter wheel (16) for severing the outer seaming wall of the seam, the axes (36, 38) of the wheels being mutually perpendicular, the working parts are carried in a common cartridge (58) of metal, mounted removably in the housing (10) of the opener, the cutter wheel and its spindle (74) being integral with each other and mounted in a separate bearing cup (66) fixed in the body (60) of the cartridge and having a thrust bearing (68) remote from the cutter wheel. The housing carries a projecting abutment (54) having a forwardly curved seam-engaging surface which enables a variety of shapes and sizes of cans to be opened.
(FR) Dans un ouvre-boîtes possédant une molette de traction (18) entraînant le pli de jonction d'extrémité (26) d'une boîte de conserve pour qu'il défile devant l'ouvre-boîtes, et une roulette de coupe (16) découpant la paroi externe du pli, les axes (36, 38) des roues étant mutuellement perpendiculaires, les parties actives sont contenues dans une cartouche métallique commune (58), montée de manière amovible dans le boîtier (10) de l'ouvre-boîtes, la roulette de coupe et son axe (74) formant une seule pièce montée dans une cuvette de support séparée (66) fixée dans le corps (60) de la cartouche et possédant un palier de butée (68) éloigné de la roulette de coupe. Le boîtier comporte une butée en saillie (54) possédant une surface d'engagement du pli de jonction courbée vers l'avant, permettant l'ouverture de boîtes de conserve de tailles et formes différentes.
