Abstract
The present invention relates to a method and apparatus for capping containers, primarily used with capping machines, that increases the engagement time that a driven roller maintains with a cylindrical side of the container cap so that the roller subtends a predetermined arc about the cylindrical axis of the container. The apparatus comprises a mechanism for resiliently urging the rotatably driven roller into the path of the container and then into engagement with the cap as the container advances on a predetermined path.
Claims6
Apparatus for rotating caps on containers, comprising
- a support frame;
- means carried by said support frame for advancing a container along a predetermined path, said container having a generally cylindrical cap positioned thereon, said cap having a cylindrical axis and an axially extending cylindrical side portion;
- at least one arm having first and second ends, said second end being mounted to said support frame for pivotal movement of said first end toward and away from said container path;
- a rotatably driven roller driven for rotation about an axis generally parallel to said cylindrical axis, said rotatably driven roller being carried by said first end of said arm;
- and
- biasing means for resiliently urging said arm first end and said roller toward said container path such that said rotatably driven roller contacts said cap cylindrical side portion on said container, maintaining said contact while said container is advanced along a portion of said predetermined path such that said roller contacts said cap cylindrical side portion while subtending an arc about said cylindrical axis of at least 10 degrees.
