Ventilated vacuum commutation structures
Ventilated vacuum structures such as pucks and rings are disclosed for carrying portions of disposable products during manufacturing. Air flow enters vacuum commutation ports on an article carrying structure from vents nearby, the vents receiving air from a side, a top or an underside of the article carrying structure.
1. A structure for carrying portions of a disposable article, said structure comprising:
an article carrying structure comprising an underside and an article carrying face;
a plurality of vacuum commutation pipes coupled to a source of vacuum;
a plurality of vacuum void spaces on said article carrying face of said article carrying structure, said vacuum void spaces coupled to said vacuum commutation pipes;
air supply void spaces on said article carrying face of said article carrying structure,
an open sidewall structure positioned between said underside and said article carrying face, said open sidewall structure allowing passage of air to said air supply void spaces.
2. A structure according to claim 1 , said structure further comprising a vacuum port plate coupled to said vacuum commutation pipes.
3. A structure according to claim 2 , said vacuum port plate comprising port plate vacuum void spaces coupled to said source of vacuum.
4. A structure according to claim 1 , said structure carried by a rotating body for rotating said structure in an orbital fashion about a first axis.
5. A structure according to claim 4 , said structure further carried by a secondary rotating body for rotating said structure rotationally about a second axis.
6. A structure according to claim 1 , said vacuum void spaces positioned adjacent said air supply void spaces.
7. A structure according to claim 1 , said vacuum void spaces receiving air from said air supply void spaces.
