Apparatus for the after-cooling of bases
First Claim
1. A method for reducing or preventing deformation of bases of blown out containers caused by non-homogenous cooling of the bases after the blown out containers are released from a blow moulding machine and transferred from the blow moulding machine to a run-out star wheel which directly follows the blow moulding machine along a conveying direction of the containers, comprising actively cooling the bases of the containers using an apparatus for cooling, commencing the cooling while the bases are still inside the blow moulding machine immediately following a time interval of at least 0.1 seconds and at most 2 seconds after a pressure release of the containers by the blow moulding machine, so that the time interval runs even during the transfer from the blow moulding machine into the run-out star wheel.

Abstract
A method of after-cooling of the bases of blown out containers, wherein after the transfer of the blown out containers from a blow molding machine to a run-out star wheel which directly follows the blow molding machine along a conveying direction of the containers a cooling of the bases of the containers is carried out by at least one apparatus for cooling the bases. The cooling of the bases of the containers starts immediately during a time interval of at least 0.1 seconds and at most 2 seconds after a pressure release of the containers by the blow molding machine after the blowing out.

17. A method for reducing or preventing deformation of bases of blown out containers caused by non-homogenous cooling of the bases after the blown out containers are released from a blow mould of a blow-moulding machine and transferred from the blow moulding machine to a run-out star wheel which directly follows the blow moulding machine along a conveying direction of the containers, comprising actively cooling the bases of the containers using an apparatus for cooling, wherein the cooling of the bases of the containers is commenced during a time interval of at least 0.1 seconds and at most 2 seconds after a pressure release of the containers by the blow moulding machine, using at least one external face cooler which applies a cooling medium to an external face of bases of the blown out containers.
