Patent ID: 8851806

Claim:
An apparatus ( 1 ) for the conveying of plastics material pre-forms ( 10 ) along a pre-set conveying path (P) with a first guide rail ( 2 ) for guiding the plastics material pre-forms ( 10 ), with a second guide rail ( 4 ) for guiding the plastics material pre-forms ( 10 ), wherein the plastics material pre-forms ( 10 ) are capable of being guided between the guide rails ( 2 , 4 ) and the guide rails ( 2 , 4 ) have in each case first support faces ( 12 , 14 ) which extend along the conveying path (P) and which support the plastics material pre-forms ( 10 ) during the conveying thereof, wherein the apparatus ( 1 ) has a stressing device ( 42 , 44 ) for acting upon the plastics material pre-forms ( 10 ) with a gaseous medium, which stressing device ( 42 , 44 ) is designed in such a way that the plastics material pre-forms are conveyed along their conveying path by being acted upon with the gaseous medium, and wherein a geometrical position of the guide rails is capable of being altered with respect to each other and wherein at least one guide rail has a second support face ( 14 , 16 ) which extends along the conveying path (P) of the plastics material pre-forms ( 10 ), in such a way that the plastics material pre-forms ( 10 ) are capable of being optionally supported by means of the first support face ( 12 ) or the second support face ( 14 , 16 ) during their conveying.
