Abstract

A device for forming a constriction on the open end zone of a metal can with a cylindrical body, comprising: (1) a support member for supporting the bottom of a can and for pushing displacement thereof in axial direction; (2) an annular anvil placed coaxially of this support member, on the side of which facing the support member an internal modelling surface is present which in the direction away from the support member has a form adapted to the desired shape of the constriction; and (3) a freely-rotating roller having a form adapted to the shape of the modelling surface, which roller can press the end zone of a positioned can forcefully against the modelling surface, which roller is carried by a support member which is driven by drive means in a circular path concentric to the annular modelling surface, wherein the axis of rotation of the freely-rotating roller extends at least approximately in the said axial direction. <IMAGE>
