Patent ID: 7966791

Claim:
A conveying device for beverage containers grouped as packs and wrapped with a film, comprising: a horizontal conveyor including an endlessly circulating conveyor chain, the circulating conveyor chain including movable members and/or meshes, a supporting structure for the packs being provided by the movable members and/or meshes and defining contact areas and/or coatings for the packs, wherein the contact areas and/or coatings include significant portions of PTFE plastic, the contact areas and/or coatings of plastic having a thickness corresponding to at least 10% of the thickness of the supporting structure covered and/or coated therewith; the conveyor chain and the contact areas and/or coatings having a plurality of openings, the openings permitting film wrapping the beverage containers to contact hot air during a shrinking of the film, the supporting structure having a Biot number equal to 2*α*r/λ and being equal to or greater than 1.0, where α is a convective heat transfer resistance of a surface of the supporting structure, r is a radius of the supporting structure, and λ is the thermal conductivity of the contact areas and/or coatings of the supporting structure.
