Liquid is moved axially along a liquid roller (1) by a transport roller (2) from end regions towards the center region by forming the transport roller (2) with two conical surface regions (4, 5) which, alternately, are tipped in engagement with the liquid roller (1) while the respectively engaged conical section (e.g. FIG. 1: 4) is axially moving towards the center region of the liquid roller (1). The transport roller can receive its drive by surface engagement, for example, by a cylindrical center portion (3) with the liquid roller, and internal gearing, and positioning of bearings (19, 20) retaining the end portions of the double-conical transport roller eccentrically with respect to the common center shaft (18) which is rotated through a reduction gearing (23-25-26), and simultaneously controls axially oscillating or reciprocating movement by a cam - cam follower arrangement (16, 17) so that synchronism between tipping of the conical surfaces in engagement with the liquid roller and axial movement thereof is insured. |
