Line for preparing and filling bottles

A facility for the production of bottles of liquid or semi-liquid products, the bottles being formed from thermoformable plastic, the facility comprising:

• a blowing device for blowing bottles from preforms, with a heating tunnel,
• a filling and finishing line, comprising one or more bottle filling, sealing, and/or capping stations, the line comprising an endless conveyor capable of receiving empty bottles ready to be filled and conveying the bottles in front of several filling, sealing, and/or capping stations, wherein a buffer conveyor interposed between the blowing device and the filling and finishing line is provided, formed mainly as an endless conveyor suitable for receiving bottles, the buffer conveyor comprising a first section used under normal flow conditions, and a second section complementary to the first section and serving as a buffer storage space under conditions of unplanned stoppage of the filling line,
• with an upstream handling device interposed between the blowing device and the buffer conveyor, having a number N4 of locations for bottles,
• and wherein the bottle storage capacity of the second section (T22), denoted N22, is dimensioned to satisfy the condition N22>N8+N1−N4−1, where
• N8 designates the number of bottles and preforms that can be received in the heating tunnel and N1 designates the number of bottles and preforms that can be received in the blowing device.
