Definitions

  • mask means In the article treatment zone, mask means closely engage a portion of the article to shield or protect a portion of the article from contact by the treatment material.
  • the mask means may take the form of counterrotating, complementary pairs of shield members which are cammed into engagement with the article at the treatment zone entrance, move in synchronism with the article through the treatment zone and are cammed out of engagement with the article at the exit of the treatment zone.
  • This invention generally relates to apparatus for shielding a portion of an article from treatment by a material applied to another portion of the article. More particularly, this invention relates to the shielding of moving articles in an article treatment zone. Most specifically, this invention relates to the shielding of moving articles in an article treatment zone by the engagement of the articles by counterrotating, complementary pairs of shield members.
  • the finish portion is a relatively critical portion which must remain in the as formed state to ensure dimensional stability for subsequent capping operations.

This has proven more effective than the static shields or air barriers used in the prior art to shield the finish portion.
  • By moving the shield members with the article being shielded a more positive seal may be achieved than is possible with a fixed shield or an air barrier.

After leaving the treatment zone Z, the shield members 34 and 36 are engaged by opening cams 50 and 51, respectively on the mask assemblies 12 and 14.
  • the opening cams 50 and 51 serve the same basic function as the open cams 42 and 44, in that they cause the shield members 34 and 36 to move away from the path of travel of the glass containers 32.

The secondary shields 108 and 109 bend inwardly at their lower ends toward the center line of the path of travel of the glass containers 32. The terminal point of the lower ends is at a point just sufficient to allow a glass container 32 of the maximum expected diameter to pass between these two plates.
  • the secondary shield supports 105 and 106 and their respective secondary shields 108 and 109 extend only through the treatment zone Z. It is only in this area that it is necessary to protect the transport mechanism from contamination with the treatment material.

  • the air, or other compressed gas which may be used, which exits through the holes 111 is forced downwardly between the plates 70 and the secondary shield 108 and must then exit downwardly along the glass container 32.
  • This flow of compressed air provides another shielding mechanism and helps ensure absolute containment of the treatment material used in the treatment zone 2.
  • the shield members 34 and 36 in theory should block any possible migration of the treatment material onto a finish portion, 113, of the glass container 32, but occasional irregularities in the configuratioon of the glass container 32 make it wise to provide this secondary source of shielding with the compressed air from the pipe 110.

  • this function is likewise performed by the cams 51 and 44 in cooperation with the opening cam follower 125 mounted on the plate 72. Since the cams 50 and 51 and 42 and 44 form complementary sets, these opening functions take place at the same time in the path of travel of the glass containers 32 and thus cause the shield members 34 and 36 to operate as a complementary unit or pair.
