Abstract

An apparatus for conveying of plastics material pre-forms, with a plurality of holding devices which engage in apertures of the plastics material pre-forms and hold them, wherein these holding devices are movable along a pre-set conveying path, with a movement mechanism which has the effect that, in addition to the movement along the conveying path, the holding devices are also movable in a direction at a right angle to this conveying path. The apparatus has at least one detection device which is suitable for detecting a defective state of a plastics material pre-form held by a holding device, and at least one first removal apparatus arranged downstream along the conveying path of the at least one detection device and which—in reaction to a signal of the detection device—permits individual removal of a defective pre-form from the holding device.
