PIA Automation Amberg GmbH

The assembly line is a production system consisting of three separate units, interconnected by conveyor belts. In the first section, consumable materials are fed in via rollers, folded, the nose clip is integrated, welded, and then cut to the correct length. The finished mask blanks are transported via an indexing conveyor and additional transport belts to the next units, which are arranged in parallel. Each of these stations feeds and welds the ear loops to the mask body.

The line is suitable for the manufacture of surgical and general medical face masks, made from single- or three-layer PP (polypropylene) nonwoven fabric.

System configuration

Each production cell is based on an aluminum profile frame with swing doors made from Makrolon. For the required process stability, the stations are mounted on a solid aluminum table plate. The control cabinets are integrated into the frame. The equipment includes, among others, 3 ultrasonic welding units, Siemens PLC control, and various pneumatic systems from Festo.
