Abstract

Disclosed is an article inflating system for engaging and inflating articles to be decorated including an endless belt assembly for engaging the article to permit inflation thereof while the article is being decorated. A plurality of spaced cup-shaped nozzles are disposed on a horizontal moving endless belt so as to allow the cup-shaped nozzles to engage the article prior to decoration and assume a sealed relation therewith while passing through the decorating station. While at the decorating station, the open end of the cup-shaped nozzle is positioned in communication with an air supply manifold disposed adjacent the decorating station to enable inflation of the article during decorating. After the label has been applied to the article, the nozzle is gradually lifted out of engagement with the decorated article while the latter is conveyed away from the decorating station.

Claims

1. A belt assembly suitable for engaging the open end portion of an article to permit the inflation thereof while said article is being decorated which comprises

an endless belt having a plurality of spaced openings extending therethrough, a plurality of cup-shaped nozzles adapted to be fastened to said endless belt, each of said cup-shaped nozzles having a central opening extending therethrough and an article engaging surface to facilitate a sealing relationship with the open end of the article to be decorated, said article engaging surface being disposed adjacent said opening and terminating adjacent an inclined portion extending outwardly therefrom, and a flanged sleeve member adapted to fasten each of said plurality of cup-shaped nozzles to said endless belt, said flanged sleeve member having a centrally open sleeve portion adapted to engage and fit within a central opening extending through said cup and a flange portion extending outwardly from said sleeve portion suitable for holding said member in engagement with the opposite side of said endless belt.

2. The assembly of claim 1 wherein said flanged sleeve member comprises a circular flange portion extending outwardly from said sleeve portion.

3. The assembly of claim 2 wherein said endless belt comprises a timing belt including a plurality of teeth-like members on one surface thereof adapted to be driven by a gear member.
