Abstract: The invention relates to a compacting device (1) for compacting empty containers, in particular beverage bottles or cans of plastic or metal, comprising at least one rotatable roller (1a, 1b), which is designed for compressing and perforating empty containers, wherein the roller (1a, 1b) has a roller base body (2a, 2b) and at least one pin element (3) protruding from the roller base body (2a, 2b), wherein the pin element (3) is formed as a hollow pin, at least the end face of the hollow pin that is facing away from the roller base body (2a, 2b) is open.

Abstract: A device is disclosed for compacting hollow bodies, in particular beverage cans, having a roller (3) that acts against a counter bearing to form a draw-in gap (23); said roller has an essentially cylindrical body (10) from which draw-in elements (12) project, which run continually in the longitudinal direction of the rollers essentially across the full length of the rollers and are arranged in parallel to one another. The object to be attained by the invention is to provide a compacting device with draw-in elements that, in addition to being effective drawing-in element, provides effective compacting. In an exemplary embodiment, the draw-in elements are formed by undulatory running strips (12) with two lateral flanks (13, 14) and a top surface (15) that connect the two lateral flanks, preferably where the edges formed are sharp.
