PPE coverall kits required for health professionals attending to infected patients in isolation wards and the Intensive Care Units (ICUs). Coveralls, or bodysuits, are glued at the seams using special tape and a sealing machine to prevent contaminants from getting in. Sewing machines and other machines required for manufacturing making PPE coverall items include -
1. Cutting machine - You need fabric cutting machines. You can use standard cutting machines, like straight knife cutting machines.
2. Sewing machine - For joining coverall components (assembling parts) you need single needle lock stitch sewing machines. Alternatively, you can use overlock machines for joining parts. These machines are available with all garment manufacturers.
"We are using the same line layout and sewing machines, we used to in making jumpsuits or baby rompers", said by a PPE coverall manufacturer.
3. Hot air seam sealing machine - This is a very important machine for ensuring PPE quality. After joining components, each seam needs to be sealed using a hot air sealing machine.

One seam sealing machine can seal about 100-110 suits a day and costs about $5,000 (Rs 3.8 lakh) a unit.
The PPE coveralls can be also made directly using the hot-air sealing machine, without pre-sewing of components.
