Abstract
An apparatus for bursting perforations on an article has a retractable burst member and an opposed second retractable burst member that imposes an impact force on the perforations on the perforated lid. Retractable burst members are arranged for vertical movement towards and away from one another in a common plane. The article is positioned in a plane substantially perpendicular to the movement of the burst members so that the burst members can engageably contact the article at the perforations. A separator is used to capture the perforated lid at the burst perforations and then retract for separating the perforated lid from the main portion of the article.
Claims8
Apparatus for bursting perforations on an article having a main body portion and a perforated lid, said perforated lid being separable from said main body portion at perforations along the periphery of said main body portion, said apparatus comprising:
- a frame having a substantially flat, movable surface for supporting said article with said perforations exposed for impact;
- a first retractable burst member and an opposed second retractable burst member arranged for movements toward and away from one another along a common axis passing through said first and second retractable burst members, said first and second retractable burst members each being arranged for applying a predetermined impact force on an end portion of said perforated lid;
- a retractable separator member arranged in said frame for capturing said perforated lid and then separating said perforated lid from said main body portion at said perforations;
- means for moving either of said first and second retractable burst members into engaging contact with a respective end portion of said perforated lid for forming at least partially burst first perforations nearest to said either of said first and second retractable burst members;
- means for moving the other of said first and second retractable burst members into engaging contact with an opposing respective end portion on said perforated lid for forming at least partially burst, second perforations nearest said other of said first and second retractable burst members;
- and,
- means for moving said retractable separator member into a first position capturing said perforated lid and then to a second position separating said perforated lid from said main body portion of said article.
