Abstract

A trimmer device includes an inner mounting block having a first central aperture for receiving a turret shaft. The inner mounting block has an inner bore. The device includes an outer mounting block having a second central aperture for receiving the turret shaft. The outer mounting block has at least one outer bore. The device includes an inner trimmer spindle positioned through the inner bore. A first end of the inner trimmer spindle includes a pilot having an inner spindle blade. The device further includes an outer trimmer spindle positioned through the outer bore. The outer trimmer spindle includes an outer spindle blade positioned at a first end. At least one of the inner mounting block or the outer mounting block is rotatable about the turret shaft to adjust for a diameter of an article such that the article is positioned between the inner and outer spindle blades for trimming.

Dependent claims

A trimmer device, comprising:

a circular inner mounting block having a first central aperture for receiving a turret shaft of a processing turret, the inner mounting block having at least one inner bore;
a circular outer mounting block having a second central aperture for receiving the turret shaft, the outer mounting block having a larger diameter than the inner mounting block, the outer mounting block having at least one outer bore;
at least one inner trimmer spindle positioned through the at least one inner bore, a first end of the inner trimmer spindle including a pilot having at least one inner spindle blade for trimming an interior of an article;
and
at least one outer trimmer spindle positioned through the at least one outer bore, the outer trimmer spindle including at least one outer spindle blade positioned at a first end for trimming an exterior of the article;
wherein at least one of the inner mounting block or the outer mounting block is rotatable relative to the other of the inner mounting block or the outer mounting block about the turret shaft to adjust for a diameter of the article such that the article may be positioned between the inner spindle blade and the outer spindle blade for trimming.

A method of configuring a processing turret for trimming an open end of an article, the method comprising:

positioning a first end of an inner trimmer spindle through an inner bore of a circular inner circular mounting block, the inner mounting block having a first central aperture having a turret shaft positioned therethrough, a second end of the inner trimmer spindle including a pilot having at least one inner spindle blade for trimming an interior of an article;
positioning a first end of an outer trimmer spindle through an outer bore of a circular outer mounting block, the outer mounting block having a second central aperture having the turret shaft being positioned therethrough, the outer mounting block having a larger diameter than the first mounting block, a second end of the outer trimmer spindle including at least one outer spindle blade for trimming an exterior of an article;
and
rotating one of the inner mounting block or the outer mounting block relative to the other of the inner mounting block or the outer mounting block, the amount of rotation being dependent upon a diameter of the article to be trimmed such that the article may be positioned between the inner spindle blade and the outer spindle blade for trimming.
