Track adjustable mounting assemblies and associated methods

A cam-actuated spindle assembly for a capping machine, comprising:

• a barrel cam having a plurality of cam tracks;
• a capping spindle defining a spindle axis along which said spindle is vertically movable, said capping spindle defining first and second vertically spaced openings;
• a cam follower;
• and
• an adjustable mounting arrangement for mounting said cam follower on said spindle in a selected one of vertically spaced first and second positions on said spindle to facilitate vertical actuation of said spindle assembly by a selected one of two different cam profiles,
• said mounting arrangement including a single mounting plate having a mounting portion on which said cam follower is mounted on a follower axis perpendicular to said spindle axis, said mounting plate being configured for attachment to said capping spindle in a selected one of first and second, relatively inverted positions to position said cam follower in the selected one of said vertically spaced first and second positions for respective engagement of said cam follower with a selected one of said cam tracks of said barrel cam,
• said mounting plate includes a positioning portion, spaced from said mounting portion and engageable with said spindle in each of said first and second positions of said mounting plate by disposition of said positioning portion in a selected one of said first and second openings defined by said capping spindle, and disposition of said mounting portion in the other one of said first and second openings.
