A protection system for a container treatment machine of the type comprising - a support structure , - a container moving device connected to the support structure and configured to carry containers to be treated in an operating space along a container treatment path , - one or more container treatment aggregates arranged along the container treatment path and arranged to manipulate the containers, wherein said protection system comprises; - a support frame comprising a base frame which can be arranged at said container treatment machine and which extends in a longitudinal direction parallel to the treatment path , and a plurality of individual support members connected to the base frame , - a plurality of individual protection panels adapted to define a separation wall between said operating space and an external environment, - a plurality of individual guide means configured to define a movement path of said individual protection panels between a closure position and an opening position thereof, - a plurality of auxiliary positioning means , wherein each of said guide means movably connects one of said individual protection panels to one of said individual support members and each of said auxiliary positioning means is interposed between one of said protection panels and one of said support members such as to form a plurality of individual panel-support-guide-positioning-modules adapted to be connected to said base frame in an adjustable position along said longitudinal direction, in such a way that the protection system is configured to cover selectable circumferential cover sections of the container treatment machine so that one or more circumferential access sections of selectable position and circumferential extension remain uncovered to allow access of the container treatment aggregates , characterized in that said plurality of auxiliary positioning means is configured to apply auxiliary forces to said individual protection panels , said auxiliary forces acting in the direction of said movement path against the force of gravity of said individual protection panels , in that said individual support members are detachably connected to said base frame for enabling substitution of said individual panel-support-guide-positioning-modules with modules having e.g. different panel sizes, different movement paths or different protection properties, and in that said auxiliary positioning means each comprises a pneumatic cylinder-piston assembly and an adjustable pressure setting device for enabling adjustment of the intensity of the auxiliary forces in order to adapt it to the weight of the protection panels, and/or to a desired force necessary to move the panels from the opening to the closure position and vice-versa. - a support structure , - a container moving device connected to the support structure and configured to carry containers to be treated in an operating space along a container treatment path , - one or more container treatment aggregates arranged along the container treatment path and arranged to manipulate the containers, wherein said protection system comprises; - a support frame comprising a base frame which can be arranged at said container treatment machine and which extends in a longitudinal direction parallel to the treatment path , and a plurality of individual support members connected to the base frame , - a plurality of individual protection panels adapted to define a separation wall between said operating space and an external environment, - a plurality of individual guide means configured to define a movement path of said individual protection panels between a closure position and an opening position thereof, - a plurality of auxiliary positioning means , <EOS>
