1. A method for transporting foamed thermoplastic polymer particles from a container through at least one pipe to a molding tool in which a molding is manufactured from individual foamed thermoplastic polymer particles, comprising(a) wetting the foamed thermoplastic polymer particles with a water comprising lubricant, and(b) transporting the foamed thermoplastic polymer particles by applying a gas stream through the pipe to the molding tool, wherein the water comprising lubricant is added in such an amount that the foamed thermoplastic polymer particles retain a moist surface and that the lubricant does not evaporate on account of the gas stream which is used for conveying the foamed thermoplastic polymer particles. 2. The method according to claim 1, further comprising adding the water comprising lubricant in the container or in the pipe. 3. The method according to claim 1, wherein the foamed thermoplastic polymer particles are wetted by spraying the water comprising lubricant onto the foamed thermoplastic polymer particles. 4. A method for transporting foamed thermoplastic polymer particles from a container through at least one pipe to a molding tool, comprising (a) wetting the foamed thermoplastic polymer particles with a water comprising lubricant, and(b) transporting the foamed thermoplastic polymer particles by applying a gas stream through the pipe to the molding tool, andwherein the foamed thermoplastic polymer particles are wetted by adding water comprising lubricant at a plurality of positions that are in succession in the direction of flow. 5. The method according to claim 1, wherein the amount of water in the water comprising lubricant is in the range from 60 to 100% by weight. 6. The method according to claim 5, wherein the water comprising lubricant additionally comprises a silicone oil, a glycerol ester or mixtures thereof. 7. The method according to claim 5, wherein the water comprising lubricant additionally comprises a pulverulent lubricant which is selected from waxes, stearates, talcum and mixtures of at least two of these components. 8. The method according to claim 1, wherein the amount of water comprising lubricant which is added is in the range from 10 mg to 4 kg, in each case based on one liter of expanded thermoplastic polymer particles. 9. The method according to claim 1, wherein the foamed thermoplastic polymer is selected from the group consisting of expanded polypropylene, expanded polyethylene, expanded polystyrene and expanded thermoplastic polyurethane. 10. The method according to claim 1, wherein the foamed thermoplastic polymer comprises an interior or exterior lubricant. 11. The method according to claim 1, wherein the gas flow is generated by applying a superatmospheric pressure at the container and/or a reduced pressure on the takeoff side of the pipe, or both. 12. The method according to claim 1, wherein the container is a filling-pressure container. 13. The method according to claim 1, wherein the foamed thermoplastic polymer particles are transported by applying a gas stream through a pipe from a container to a filling-pressure container and by applying a gas stream through a pipe from the filling-pressure container to the molding tool.
