Claim Text:
1. A method of conveying plastics material pre-forms having carrier rings, comprising conveying the plastics material pre-forms between a first roller rotating at least for a time about its longitudinal axis (L 1 ) and a second carrier body, supporting the plastics material pre-forms during the conveying thereof both by the first roller and by the second carrier body, wherein at least the first roller or the second carrier body has a length-to-diameter ratio of greater than 35, wherein the first roller is driven at an operational rotational speed of greater than 400 r.p.m., and has a main body produced from a first light-weight, dimensionally stable material, and a layer surrounding the main body in the peripheral direction thereof and produced from a second material different from the first material, wherein the layer is formed of a reduced friction material as compared to the material forming the main body, and contacts the plastics material pre-forms at least for a time during the conveying thereof, passing the plastics material pre-forms from a chute to the first roller and the second carrier body, while supporting the main bodies of the plastics material pre-forms on their carrier rings as they are moved between the first roller and the second carrier body, and wherein the first roller and the second carrier body are adjoined by removal rails between which the plastics material pre-forms are further conveyed under action of gravity.
