Blades and anvils

20 fewer minutes of downtime, from the first recorded failure.

A real plant case documented in ProFACTOR. Read only: nothing here can be edited.

A blades-and-anvils failure on a multipacker, followed through ProFACTOR from start to finish: downtime, actual repair time and root-cause analysis aimed at preventing recurrence.

How the event translates into indicators

MTTR · Mean time to repair
95 min

Average of two stoppages on the same machine, despite different causes.

(135 + 55) ÷ 2 = 95 min

  • Blades and anvils: 135 min
  • Infeed chain: 55 min
Availability · Not full OEE
71.9 % → 76.0 %

+4.2 percentage points

Shift: 480 min. Recorded downtime: 135 min; comparison without searching: 115 min. Performance and quality do not change in this comparison.

(480 − 135) ÷ 480 → (480 − 115) ÷ 480

MTBF · A single interval
20 h 35 min

Closed: Sep 25, 10:15 → next start: Sep 26, 06:50. This is one interval between stops on the same machine, not an average MTBF or a judgment of normal frequency.

The 75 → 55 min comparative cycle and recorded 135 min downtime are different data. Calculated recovery represents avoiding 20 min of searching; results are not guaranteed for other plants.

From a worn blade to the root cause

  1. WHY 1

    Why were packs sticking together and the blades taking impacts?

    Because the blade and anvil were worn and no longer cut or sealed evenly.

  2. WHY 2

    Why did they reach this level of wear without earlier detection?

    Because sealing-system calibration was not checked as frequently as the wear required.

  3. WHY 3

    Why was it not checked that frequently?

    Because jaw adjustment was left to each technician’s judgment at shift change.

  4. WHY 4

    Why was it left to individual judgment?

    Because technicians did not all have the same experience in calibrating and adjusting sealing systems.

  5. WHY 5 · ROOT CAUSE

    Why did technicians have different adjustment criteria?

    Insufficient training for less-experienced technicians.

Corrective action

Schedule training for less-experienced technicians in sealing-system calibration and adjustment.

Triple jaw360 ppm45 min110 min90 min25.00

The time saving stays the same; output during those minutes changes. Each traditional cycle combines part replacement with the example’s fixed 65 min.

How the time is saved

The 20-minute saving is the same for all three machines; the repair is not. The technician calibrates, installs and tests the same way in both cycles.

What changes between machines is how much each one produces while stopped for those 20 minutes.

What each column of the table means

Speed (ppm)
Individual packs per minute the machine produces while running. It defines how much production is lost per stopped minute: 80, 220 or 360.
Blade and anvil replacement
The repair time itself (10, 30 and 45 min). It is the same in the traditional cycle and the ProFACTOR cycle.
Traditional cycle
Total stoppage time, from machine stop to normal production again. It includes the replacement, the other steps (65 min in all three rows) and the 20 minutes of management that ProFACTOR removes. It gives 75, 95 and 110 min.
ProFACTOR cycle
The same cycle without those 20 minutes: 55, 75 and 90 min.
Boxes recovered
The production no longer lost thanks to those 20 minutes. Calculated as speed × 20 min ÷ 288 packs per box (12 packs per multipack × 24 multipacks per box).
Production no longer lost, by machine type.

Double jaw220 × 20 = 4,400 packs15.28
Triple jaw360 × 20 = 7,200 packs25.00

Production lost in the base case (single jaw)

  • With the traditional cycle, 75 × 80 = 6,000 packs are lost — 20.83 boxes.
  • With ProFACTOR, 55 × 80 = 4,400 packs are lost — 15.28 boxes.
  • The difference is 5.56 boxes.

The difference is not repairing faster. It is avoiding lost time.
