Claims18
A trim station for trimming a flange of a container comprising:
- a rotating primary knife;
- and
- a secondary knife mounted on a movable member,
- wherein the secondary knife is moved into a cutting position by advancing the movable member in a direction parallel to a longitudinal axis of the container, and
- wherein an axis of rotation of the primary knife and an axis of rotation of the secondary knife are offset such that they do not intersect the two axes are non-coplanar and exist in planes that are parallel to each other.
An apparatus for trimming a flange of a container, comprising:
- a plurality of trim stations each comprising:
- a rotating primary knife;
- and
- a secondary knife mounted on a movable member, wherein the secondary knife is moved into a cutting position by moving the movable member in a direction parallel to a longitudinal axis of the containers
- wherein an axis of rotation of the primary knife and an axis of rotation of the secondary knife are offset, such that they do not intersect and the two are non-coplanar and exist in planes that are parallel to each other.
