Set-up question

How do you set side belts on a spindle capper?

Use a repeatable record for side-belt contact and bottle control.

Direct answer

How do you set side belts on a spindle capper?

Side belts on a spindle capper should be set around the approved filled bottle so the container is supported through the tightening zone without crushing, twisting, scuffing or forcing it away from the cap path. Use a first-off check, record the belt gap and height, then verify cap height, torque evidence and bottle condition.

Practical setting sequence

Start with the approved filled bottle and cap combination.
Set guide rails so the bottle enters squarely and does not drift before the capper.
Set side-belt height to contact a stable part of the bottle body.
Close the belt gap until the bottle is controlled but not distorted.
Run first-off samples and check cap height, thread engagement and visible marking.
Record the final settings for the format.

Signs the side-belt setting is wrong

Bottle spin

The bottle rotates during tightening or loses thread engagement before the spindle wheels finish the cap.

Sidewall marking

Belts are too tight, too high, too low or unsuitable for the bottle finish and label area.

Cap variation

Cap height or torque evidence varies because the container is not entering the tightening zone consistently.
