Abstract
Disclosed is a lid seaming apparatus that uses a seam forming roller and a seam sealer roller that move in a direction that is substantially parallel or is preferably less than 10 degrees from a tangent line drawn through the intersection point of the seam forming roller and the seam sealer roller with a seaming chuck. A displacement between the seaming chuck and the seam sealer roller that is slightly less than the thickness of a sealed seam allows for a high degree of adjustment and the creation of forces that are sufficient to cause the seam to properly seal.
Claims17
A method of seaming a lid to a can comprising;
- positioning a can lid and can in a rotary seaming chuck so that said can lid and said can rotate in response to rotation of said seaming chuck;
- moving a seam forming roller in a direction towards said seaming chuck that forms an angle of less than approximately 45 degrees with a tangent line that is tangent to said seaming chuck at an intersection point of a fully formed seam and said seam forming roller;
- moving a seam sealer roller in a direction towards said seaming chuck that forms an angle of less than approximately 45 degrees with a tangent line that is tangent to said seaming chuck at an intersection point of a fully sealed seam and said seam sealer roller.
A lid seaming apparatus comprising:
- a seaming chuck that receives a can lid on a can and spins the can lid and can on a base;
- a seam forming roller that is mounted on a seam forming translating mechanism that moves said seam forming roller in a direction towards said seaming chuck that forms an angle of less than approximately 45 degrees with a tangent line that is tangent to said seaming chuck at an intersection point of a fully formed seam and said seam forming roller;
- a seam sealer roller that is mounted on a seam sealer translating mechanism that moves in a direction towards said seaming chuck that forms an angle of less than approximately 45 degrees with a tangent line that is tangent to said seaming chuck at an intersection point of a fully sealed seam and said seam sealer roller.
