Abstract

A device and method tests preforms that are rotationally symmetrical with respect to an axis of rotation during their conveyance along a conveyance path. The device and method tests only a statistically relevant number of produced preforms, thus allowing substantial reduction in the constructive complexity required for aligning the preforms prior to being tested. A certain number of preforms that have not been correctly aligned are allowed to continue along the conveyance path without being tested.
