Rod manufacturing machine for manufacturing products of the tobacco processing industry with - a format garniture with - a format base and one or more garniture components (6, 7), and - a garniture tape performing a transport movement, and - a wrapping strip resting on the garniture tape and moved by the transport movement of the garniture tape, wherein - the format base and the garniture components (6, 7) each have a shaping surface against which the garniture tape or the wrapping strip resting thereon are in contact, wherein - the shaping surfaces have a shaping which forces the garniture tape during the transport movement together with the overlying wrapping strip out of a flat alignment into an alignment which is U-shaped in cross-section, wherein - the format base and/or at least one of the garniture components (6, 7) have a higher hardness at least in a section of their shaping surface than in the region of the remaining surfaces, characterized in that - the format base and/or at least one of the garniture components (6, 7) and/or a surface of the rod manufacturing machine has in a section a recess which, together with an opposite surface of the format base and/or of the garniture component (6, 7) and/or a surface of the rod manufacturing machine, forms a flow channel through which a cooling liquid flows, wherein - the recess is arranged in one of the surfaces of the format base and/or of the garniture components (6, 7) which has the lower hardness, wherein - at least one rib aligned in longitudinal extension of the flow channel is provided in the flow channel, wherein - the rib is dimensioned in such a way that it divides the flow channel into two partial flow channels (13, 14, 15) which are separated from one another in terms of flow at least in sections. - a format garniture with - a format base and one or more garniture components (6, 7), and - a garniture tape performing a transport movement, and - a wrapping strip resting on the garniture tape and moved by the transport movement of the garniture tape, wherein - the format base and the garniture components (6, 7) each have a shaping surface against which the garniture tape or the wrapping strip resting thereon are in contact, wherein - the shaping surfaces have a shaping which forces the garniture tape during the transport movement together with the overlying wrapping strip out of a flat alignment into an alignment which is U-shaped in cross-section, - the format base and/or at least one of the garniture components (6, 7) have a higher hardness at least in a section of their shaping surface than in the region of the remaining surfaces, characterized in that - the format base and/or at least one of the garniture components (6, 7) and/or a surface of the rod manufacturing machine has in a section a recess which, together with an opposite surface of the format base and/or of the garniture component (6, 7) and/or a surface of the rod manufacturing machine, forms a flow channel through which a cooling liquid flows, wherein - the recess is arranged in one of the surfaces of the format base and/or of the garniture components (6, 7) which has the lower hardness, wherein - at least one rib aligned in longitudinal extension of the flow channel is provided in the flow channel, wherein - the rib is dimensioned in such a way that it divides the flow channel into two partial flow channels (13, 14, 15) which are separated from one another in terms of flow at least in sections.
