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.
