CAN SEAMER MACHINES

WHAT IS A CAN SEAMER?

A can seamer machine also referred as can closer or can sealer is a machine used to hermetically seal the lid to the can body. The lid, end or cover can be made of tinplate steel or aluminum while the body can be tinplate, aluminum, composite (cardboard like) or plastic.

The seam achieved is generally leak proof, but this depends on the product being canned. The seam is made by mechanically overlapping the two layers to form a hook. Different parameters of the hook are measured and monitored to check the integrity of the seam under different conditions. The shape of the double seam is determined by the shape of the seaming roll profile and the relative position.

Two seaming options:

• Rotary can seaming operation: During the can seaming process, the seamer chuck and the two seaming rolls (1st and 2nd operation) stand still while the can rotates/spins.

• Still standing can seaming operation: During the can seaming process, the seamer chuck holds the can while the four seaming rolls (two 1st and two 2nd operation) rotate around it.

In both cases the first operation roll folds the lid (end/cover) and then the second operation rolls tighten the resulting seam. The first operation seam is critical to avoid problems like wrinkles (tightness issues) and leaks. The shape of the seam is determined by the shape of the first operation roll, the second operation roll, their relative positions and distances, lifter height, lifter pressure. Any damage or problems to the seamer or seamer tools can cause severe problems to the double seam like seam bumps, wrinkles, sharp seams, and open seams.

JK SOMME CAN SEALERS | Heavy duty construction – made for lasting a life time

Since 1905, JK SOMME legendary can seamers have a reputation for being almost indestructible, real working mules. How many SOMME machines over 60 years old are still working in the canneries worldwide? You would be surprised. A family tradition now in its third and fourth generation remaining faithful to two basic principles based on quality and innovation.

100% mechanical – all elements geared up

Movement is transmitted by large, robust and accurate gears. With the only help of our hands machine can be easily moved by just turning the seaming head. Nowadays more and more can seamer manufacturers are applying electronic solutions such as servos for replacing mechanical connections. Believe this can be a solution for high tech ultra clean factories (beer and beverage) but not for the 95% rest of canneries (fish, meat, vegetables, fruits…).

In JK SOMME we believe a machine must be ready for working in the middle of the dessert or the jungle with lack of skilled technicians, no commercial parts, power shutdowns…Summing up: work under the worst scenarios.

Stainless steel finish – reduced corrosion

The intensive use of stainless steel allows the can seamer to work in extreme conditions, under the harshest, saltiest and steamiest environments. Machine will not suffer from corrosion and therefore its elements will last longer. This is especially important when working products with high grade of pH such as tomato sauce, brines, etc.

​CE compliance – made in Europe​

“CE” is the abbreviation of French “Conformité Européene” which means “European Conformity”. By tagging the CE marking to a can seamer, we declare that the machine meets all the legal requirements for CE marking and can be sold throughout the EEA (European Economic Area).

The two main benefits that CE marking brings to machine producers and consumers within the EEA:

• Producers know that can seamers bearing the CE marking can be traded in the EEA without restrictions.

• Consumers enjoy the same level of health, safety, and environmental protection throughout the entire EEA.
