The invention proposes a method for positioning protective screening ramps of a station for heating preforms, on the occasion of a change of format, the heating station comprising: —members for transporting preforms; —at least one pair of parallel longitudinal screening ramps for protecting necks against heat, which ramps are parted in order to leave a slot through which the preforms progress; —a motorized device for moving the ramps transversely. The method includes a preliminary calibration step which consists in arranging at least two calibration elements between the two protective screening ramps occupying an initial position, and manually causing the protective screening ramps to move into a calibrated position in which they are each in simultaneous contact with the two calibration elements.

Provided is a method for treating plastic preforms, wherein the plastic preforms are transported in a row by a feed transport device and are separated by a separating device, wherein the separating device has a carrier which is rotatable with respect to a predetermined axis of rotation and has on its outer circumference a plurality of recesses for receiving the plastic preforms in a takeover area and which are equidistant from one another in a circumferential direction of the carrier, wherein the separating device transporting the plastic preforms separately along a predetermined transport path section, and wherein the separating device transferring the plastic preforms in a transfer area to a further transport device which transports the plastic preforms further at a predetermined transport speed. During a start-up process, the separating device increases a transport speed at which it conveys the plastic preforms from the takeover area to the transfer area.

Apparatus for heating plastic preforms with a transport device which transports the plastic preforms during their heating along a predetermined transport path, with a first feed transport device which directly transfers the plastic preforms to the transport device in a transfer region, wherein this first feed transport device having a carrier which can be rotated with respect to an axis of rotation and has a plurality of holding devices which hold the plastic preforms, wherein each of these holding devices is in each case assigned an application device, wherein these application devices being arranged on a carrier which can be rotated about an axis of rotation.

A preform conveying device (100) of the invention includes a control unit that detects an arriving time at which a conveyor jig arrives at a reference position based on an output of a first encoder, and commands a second motor to move a conveyor arm to a target position at regular intervals from the arriving time. The target position in each command is a position obtained by adding, to a current position of the conveyor jig which is obtained based on a latest output of the first encoder which was obtained when the command has been issued, a moving distance by which the conveyor jig has advanced during a delay time T which spans from a time when the latest output is outputted from the first encoder to a time when the command is received by the second motor.
