Abstract: Elongated wrappings made of sheet material comprising a first metal component and a second heat-sealable component are end sealed by successively feeding the wrappings, by means of a conveyor, in a first given direction and along a given path through a sealing station; varying the traveling speed of the wrappings in relation to the conveyor at the sealing station; and induction heating, for a given length of time during a relative pause, the first component at the ends of each wrapping, to melt the second component.

Abstract: A device for use in machines for wrapping blocks e.g. soap tablets (1) comprising a drum (3) which rotates intermittently and has diametrically opposed seatings (4) for the tablets (1), a station (6) for receiving a tablet (1) expelled from an adjacent seating (4) partially wrapped in an associated piece of wrapping paper (2), and means (11, 12) for removing the tablets (1) in succession from the station (6). The device comprises a hopper (20) movable alternately between the station (6) and a position remote from it, in register with the path of transport means (11,12) and orientated relative to the path so that the hopper (20) can be intercepted by pushers (12) of the transport means (11,12), the hopper (20) being arranged to receive a tablet (1) and its associated piece of wrapping paper (2) expelled from the drum (3) at the station (6) and to deliver them into said remote position to be engaged and carried away by a pusher (12) of the transport means (11,12).
