Abstract: The present invention aims at closing a receptacle (1) provided with an opening (2) as tightly as possible while keeping low the amount of material required for a closure (3) used for this purpose. To this end, a tool (10) is suggested that closes the opening (2) of the receptacle (1) by means of the closure (3). The tool (10) comprises a tool plate (12) configured such that it is adapted to be introduced into the opening (2) of the receptacle (1). The tool further comprises at least one roll (11) that is arranged on the tool plate (12). The at least one roll (11) is adapted to be deflected radially outwards from a starting position into a closing position and returns to its starting position, so that a radial force can be caused to act on a closure rim (4) of the closure (3) for a limited period of time, the closure rim (4) being arranged between the at least one roll (11) and the receptacle inner side (5).

Abstract: A lid suitable for closing a metal can includes a metal ring onto which a peelable membrane is sealed. An inner annular part of the metal ring is equipped with a roll defining an annular space therebetween. The first connection portion of the roll and the second connection portion of the inner annular part opposite are sealed to one another by element of a heat-sealing material to form a seal sealing the annular space so at to protect the free edge of the roll. The invention also relates to a method for producing such a lid.

Abstract: Disclosed is a method for manufacturing an endless belt, of the flat type made of metal material, designed to be wound around at least one indexed pulley provided with teeth. The endless belt includes, for the one part, locations which are each designed to receive a product to be conveyed and, for the other part, indexing perforations. The manufacturing method includes the following successive steps: a) a step of supplying a flat band made of the metal material, b) a step of closing the band by welding of the transverse edges thereof via a weld seam, and c) a step of perforating the weld seam, at the at least one longitudinal indexing line, in order to form at least one additional indexing perforation that is also designed to engage with the teeth of the at least one indexed pulley.
