A machine for the production of a component for an aerosol generating article, the machine including: - a buffer station for a sheet of material, the buffer station including: ∘ fixed sheet guides ; ∘ movable sheet guides which are movable in a reciprocating manner in a direction towards the fixed sheet guides and in a direction away from the sheet fixed guides; ∘ an actuator for moving the movable sheet guides , wherein the fixed and movable sheet guides together define a zig-zag trajectory for the sheet having a variable length for varying the total length of the sheet of material in the buffer station ; characterized in that it also includes: ∘ supports for the sheet , the supports being arranged so that, when the movable sheet guides are moved towards the fixed sheet guides , at least one of the movable sheets guides is interposed between two different supports ; ∘ an air system connected to the supports ; ∘ wherein each of the supports defines an outer surface, at least one of the outer surfaces having a first portion in which a sucking action is exerted by the air system to attract the sheet towards the outer surface and a second portion in which a blowing action is exerted by the air system to push the sheet away from the outer surface . - a buffer station for a sheet of material, the buffer station including: ∘ fixed sheet guides ; ∘ movable sheet guides which are movable in a reciprocating manner in a direction towards the fixed sheet guides and in a direction away from the sheet fixed guides; ∘ an actuator for moving the movable sheet guides , wherein the fixed and movable sheet guides together define a zig-zag trajectory for the sheet having a variable length for varying the total length of the sheet of material in the buffer station ; characterized in that it also includes: ∘ supports for the sheet , the supports being arranged so that, when the movable sheet guides are moved towards the fixed sheet guides , at least one of the movable sheets guides is interposed between two different supports ; ∘ an air system connected to the supports ; ∘ wherein each of the supports defines an outer surface, at least one of the outer surfaces having a first portion in which a sucking action is exerted by the air system to attract the sheet towards the outer surface and a second portion in which a blowing action is exerted by the air system to push the sheet away from the outer surface . ∘ fixed sheet guides ; ∘ movable sheet guides which are movable in a reciprocating manner in a direction towards the fixed sheet guides and in a direction away from the sheet fixed guides; ∘ an actuator for moving the movable sheet guides , wherein the fixed and movable sheet guides together define a zig-zag trajectory for the sheet having a variable length for varying the total length of the sheet of material in the buffer station ; characterized in that it also includes: ∘ supports for the sheet , the supports being arranged so that, when the movable sheet guides are moved towards the fixed sheet guides , at least one of the movable sheets guides is interposed between two different supports ; ∘ an air system connected to the supports ; ∘ wherein each of the supports defines an outer surface, at least one of the outer surfaces having a first portion in which a sucking action is exerted by the air system to attract the sheet towards the outer surface and a second portion in which a blowing action is exerted by the air system to push the sheet away from the outer surface . <EOS>
