FIELD: transport, package. ^ SUBSTANCE: device relates to cork stoppers for glass or other vessels and can be used in various industrial branches. It comprises base, fixed mandrel with tapered hole, two cylindrical semi-mandrels with slots made on their side surfaces, pusher and four tie rods with pins on their lower ends. Note here that said tie rods are rigidly jointed with pusher by their upper ends, while pins are fitted in semi-mandrel slots. Semi-mandrels are arranged above fixed mandrel to move thereon toward the device vertical axis and therefrom. Both semi-mandrels are made so that, when in full contact, they make cylindricalhole with diametre equal to that of the cork. Slots of side surfaces of semi-mandrels are made so that with pushers with tie rods moving downward, semi-mandrels approach to get in contact, while in subsequent motion of the pusher downward, they do not move. ^ EFFECT: perfected design. ^ 4 cl, 5 dwg |
