It is only through the ability to consistently achieve the same, optimal settings time after time that the need for adjustments after restarting the line can be eliminated. To begin, all position adjustments must be made measurable. This can be done by applying scales or rulers with pointer to all adjustable parts. Measurable settings eliminate operator judgement in achieving proper setup. Digital indicator dials, are an excellent means for measuring setup adjustments.
Some machines require height adjustments set by cranks.
While scales may serve the same function, indicator dials are more precise and give an easily read indication of adjustment. When there are only two setup positions, adjustable stops may be used. These stops are set so as to limit adjustment. For example, a capper might have a lower and upper stop. When running a small bottle, the capping head is lowered until it touches the lower stop.
