Gaiter seal and working head of a device or machine for producing and/or treating containers, said working head comprising such a gaiter seal

An apparatus comprising a gaiter seal (12) that extends along an axis, said gaiter seal (12) comprising a plurality of gaiter modules (13), each of which is a unitary structure, wherein said plurality of gaiter modules comprises first and second gaiter modules that are adjacent to each other, wherein each of said first and second gaiter modules comprises:

• a first coupling section (13.1),
• a second coupling section (13.2), which forms a support-and-sliding element that radially supports said first and second gaiter modules and guides said first and second gaiter modules during movement thereof along said axis, said first and second coupling sections being annular coupling sections, and
• a gaiter section (13.3) that extends between said first and second coupling sections, wherein coupling sections of adjacent gaiter modules, including said first and second gaiter modules, are interconnected with one another along said axis,
• wherein said first and second coupling-sections of said first gaiter module are structurally different from each other,
• wherein said first and second coupling-sections of said second gaiter module are structurally different from each other,
• wherein said first coupling-section of said first gaiter module is structurally identical to said first coupling section of said second gaiter module,
• wherein said second coupling section of said first gaiter module is structurally identical to said second coupling section of said second gaiter module,
• wherein said first coupling section of said first gaiter module is shaped so as to penetrate and mate with said second coupling section of said second gaiter module,
• wherein, as a result of said second coupling section of said second gaiter module having been penetrated by said first coupling section of said first gaiter module, said first coupling section of said first gaiter module and said second coupling section of said second gaiter module become interconnected and said first and second gaiter modules adjoin each other and are adjacent to each other,
• wherein said first coupling section of said first gaiter module is rigid,
• wherein said second coupling section of said first gaiter module is rigid,
• wherein said first coupling section of said second gaiter module is rigid, and
• wherein said second coupling section of said second gaiter module is rigid.
