A Seam Vee is an irregularity on the cover hook when the cover material does not form smoothly. The material splits causing a “V” shaped opening on the face of the cover hook.

POTENTIAL CAUSES:

• Improper first operation seaming roll setting.

• First operation roll profile too wide.

• First operation roll worn.

• Product trapped in the double seam.

• Damaged cover curl.

• Timing of seamer, feed chain and cap feed turret to seaming turret.

• Excessive seaming stock.

• Wrinkle along the curl and crown of the end.

SUGGESTED REMEDY:

• Reset first operation roll tightness and height relationship to seaming chuck.

• Replace with proper first operation roll with narrower groove profile.

• Replace with new first operation roll.

• Check for overfills and proper filling procedure.

• Damaged ends at cover feed can cause vees. Insure covers are not damaged prior to feeding into seamer, and that the seamer is properly set up.

• Refer to section in manual on timing of equipment for seamer being used.

• Discuss with end manufacturer.
