Definitions

  • the technique mostly adopted at present provides for the centering system to be neither of the single-acting type, nor of a purely mechanical type, but to comprise a set of independent pneumomechanical modules.
  • This structure allows, at least in theory, to obtain an improved centering of the reel also along the longitudinal axis - in that the single modules determine the centering of the reel core one independently from the other - so that it may be possible to perfectly center also a reel whose core is not perfectly cylindrical lengthwise.
  • the two pneumomechanical modules are operatively independent - which allows a differentiated extraction of the two groups of keys, and thus a longitudinal adjustment of the tiles to the irregularities of the reel core - but the compressed air supplying path crosses the expanding pads, leading the pneumatic system to be operatively connected to the centering system, which is not always desirable.
  • the supplying of compressed air through the expanding pads can easily take place only in correspondence of the two ends of said pads, while it gets complicated to form other pressure intakes along the length of the pad for any further pneumomechanic modules, thereby positively hampering the production of an shaft with more than two pneumomechanical modules.
