Abstract
The contribution describes a device for folding flat filter masks civil protection with nano fiber layer. This layer is in a protective case and requires special treatment. The aim of the research was the development of a new type provided that the production of the filter will be large series. Activity in the folding machine must be in controlled mode, without human intervention. The main problem is the mechanical rigidity of the needles that are control by pneumatic system. These needles are essential for equal foundation fabric. In this paper will be made the strength check by FEM. Was checked deformation and stress of the needles. They were designed structural measures to ensure the function of the mechanism.
