Abstract
An apparatus for producing containers from paper or paper-like material. The container has a lateral surface made of a wound sheet-like segment, of which segment edges arranged on longitudinal sides overlap and form a region of overlap, and a pan-like termination element. The lateral surface and the termination element are connected to one another in an essentially liquid-tight manner by a skirt, and at least one pressing ram is provided for pressing and sealing the skirt, the pressing ram subjecting the skirt to essentially radially directed pressure. The pressing ram has a radially projecting protrusion in a portion provided for the purpose of acting on a boundary portion of the region of overlap of the lateral surface of the skirt.
