Abstract: The invention includes a device for supplying preforms having a collar. The device comprising a file-forming slide for the preforms, and the slide comprises a fixed frame and elements for guiding the preforms. The guiding elements are mounted so as to be adjustable in terms of position on the frame so as to be adapted to different formats of preform. The frame comprises support plates that are fixed in a reference position on the frame by removable fastening means, the guiding elements being mounted so as to be adjustable on the support plates.

Abstract: The invention includes a method for adjusting a preform conveyor. The method includes a preadjustment phase during which preforms of a first format are conveyed. Each preform is supported under its collar by guides delimiting a lateral space and the body of each preform is guided by rails delimiting a holding gap. The rim of each preform is guided by a top guide defining a maximum height, and the lateral support space, the lower holding gap, and the maximum height are independently adjusted with respect to the first format. The values of the first format are recorded. In order to convey preforms of a second format, the preadjustment phase is carried out, and in order to convey pre-forms of the first format, the lateral space, the holding gap and/or the maximum height are adjusted automatically according to the recorded values of the first format. The invention also relates to a suitable adjustment device.
