A method for blow molding containers in blow molds of a device operated with the recovery of air from the blow molds, where operation is accomplished consecutively in a preblow stage with a low pressure and at least two further blow stages with respective higher pressures, and where subsequently, in a recovery phase with several pressure stages, air is fed from the respective blow mold, air from the blow mold is first fed into the volumes allocated to the preblow stage, with priority over a feeding at least into the volume allocated to the pressure stage following the preblow stage. Further, a blow control and a control means for the pressure in the volume, where the blow control has a program section for primarily feeding air first into the volume, and possibly for limiting the pressure in the volume to a multiple of the pressure.

An apparatus for sorting piece goods may include a receiving surface which can rotate about a predefined rotation axis and is designed to receive the piece goods. The apparatus may include a first guide rail for guiding the piece goods, wherein this guide rail has a gap through which one region of the piece goods passes and by means of which another region of the piece goods is held. The apparatus may include a turning device which pivots the piece goods with respect to a longitudinal direction of the piece goods. The apparatus may include a separating device which separates out some of the sorted piece goods which are not guided in a predefined manner by the first guide rail or by the turning device. The turning device may be arranged upstream of the separating device in the movement direction of the piece goods.

A stretching rod holding arrangement may include a stretching rod for expanding plastic containers, wherein the stretching rod has an elongate rod-shaped main body and a holding body, which protrudes with respect to this rod-shaped main body in a radial direction of the rod-shaped main body. The arrangement comprises a receiving space for mounting the stretching rod, wherein at least one region of the holding body can be received by this receiving space, and the receiving space has a lower boundary wall in the longitudinal direction of the stretching rod. An opening is provided in this lower boundary wall, through which opening the main body of the stretching rod can pass. An arresting mechanism, which can be moved with respect to the receiving space between at least two positions, may be provided above the lower boundary wall in the longitudinal direction of the stretching rod. In the first position, the arresting mechanism allows the passage of the holding body in the longitudinal direction of the stretching rod, and in the second position prevents the passage of the holding body of the stretching rod.
摘要:
An apparatus for forming plastic pre-forms into containers with a blow mold which has at least two movable blow mold parts which, when closed form a container-forming cavity. The first blow mold part is removably arranged on a first blow mold carrier shell part, and the second blow mold part is removably arranged on a second blow mold carrier shell part. The first blow mold carrier shell part is movable with respect to the second blow mold carrier shell part for opening the mold. A holding device holds at least one blow mold part on the respective blow mold carrier shell part. The holding device has an actuating member extending through an opening in a wall of the blow mold carrier shell part. The actuating member is movable relative to the wall, and a first holding element for holding the blow mold part is arranged on the actuating member.
