Configuration of a machine for engaging a cap with a container

A computer-implemented method of configuring a capping machine which, when configured, is operable to arrange a cap in a given angular position in relation to a neck on a container and to rotate the cap in relation to the neck to fully engage a threaded portion of the cap with a corresponding threaded portion of the neck, said method comprising:

• sequentially selecting an angular position from a predefined set of angular positions of the cap until a termination condition is fulfilled, wherein the angular positions in the predefined set correspond to different orientations of the threaded portion of the cap relative to the threaded portion of the neck,
• operating, for each selected angular position, the capping machine to perform a plurality of capping operations, in which each of a plurality of caps is arranged in the selected angular position and rotated to fully engage with a respective neck on a respective container, and
• evaluating the plurality of capping operations for consistent capping performance at the selected angular position,
• wherein the termination condition requires detection of said consistent capping performance for a sequence of adjacent angular positions that correspond to a sequence of spatially adjacent orientations of the threaded portion of the cap relative to the threaded portion of the neck, and
• wherein said method further comprises:
• configuring the capping machine by setting the given angular position in relation to the sequence of adjacent angular positions.
