A new wheeled version of the INOX 10M was shipped to New Zealand’s largest dairy company at the end of last week. We were able to include multiple modifications, including an interlock switch on the bottom guard plate and for the support stand to facilitate the addition of castors.
As part of the commissioning process, we always set the seamer to the can makers’ double seam specification.
The process we follow is to firstly measure the 1st Operation external seam thickness using a can seam micrometer. We then measure the countersink depth which combined with seam thickness will allow us to picture the profile of the seam. Using the seam saw, we can also take a cross section view of the 1st Op to get a complete visual representation of the profile.
Once the 1st Op is within the specification, we bring in the 2nd Op roll until the target seam thickness is met. Using the seam saw and camera, it is then possible to measure all the internal parameters to check for a tight seam. Using the imaging software allows us to be as accurate as possible when checking seams.
A sample of around 20 cans is put through the seamer and then cross sectioned with all results recorded. We then produce a double seam report for the customer with a visual graph displaying the results.
We are often presented with cans and lids from customers without a double seam specification or chuck lip drawing. However, we are able to calculate the double seam parameters using our extensive library of data and knowledge. We also have the ability to create a chuck lip profile from a lid sample provided.
