Lemu Group engineers mask-making machine

The equipment was developed by Teyman, a Lemu Group company located in Valencia, Spain.

‘Given the shortage of masks in Europe, Lemu Group decided to do what it does best – build robust machines with stable production,’ said Naiara Fernandez, sales leader of Lemu Group’s non-woven business unit. ‘We wanted to help curb this disease, which spreads so fast. In record time, we were able to develop a surgical production line from scratch.’

Lemu Group’s latest launch, a machine manufacturer entirely in Europe, delivers enhanced productivity and full automation while adhering to all European safety standards.

‘While there are many machines out in the international market, we believe we are offering something different,’ added Fernandez. ‘The majority of foreign machines on the market lack the automation and quality that Lemu Group provides, and they are clearly not operating within the same safety standards.’

The mask-making machine is equipped with four unwinders, which enable the production of masks with three and four layers. Each reel also has an independent tension control.

‘We can work with different materials, and the adjustments are always simple,’ stated Fernandez. ‘With just a few manual adjustments, the machine works properly and efficiently. This is critical because the materials used in mask production frequently change in terms of quality.

‘We have worked diligently to ensure the welding point of the mask’s ear loop can be adjustable. Depending on the quality of the ear loop and mask material, this welding point can vary quite a bit, so is very important to have the material well-guided. The positioning of the masks in the welding system are servo-made, which guarantees that the position of the mask is accurate and eliminates positioning errors.’

The machine is equipped with a system to place the ear loops inside the mask, and the mask grouping system in each welding line is independent.

‘We group the masks, and we use one pneumatic pusher in order to make sure that the masks will be together during transportation. At the entrance of the packaging system, the machine is equipped with one selection system so that the Flow Pack packaging unit can have constant feeding and the mask forming unit never stops,’ concluded Fernandez.
