Dog marks on the canbodies

Possible causes:

  • The timing of the rounding process is too late.
  • The rolled can body is clamped or caulked in the catch station.
  • One or more transport fingers is / are twisted or lost.
  • The tension of one or both transport finger timing belts is too low.
  • Check the transport finger’s offset.
  • The final pusher fingers of the Synchrostar are taking over the can body from the transport fingers too late.
  • The precalibration is set too tight, or some precalibration rollers are not easily turning anymore.
  • Check if any groove of the z-bar section is worn.
