Method for manufacturing filter element for filtering e.g. air, used in motor vehicle, involves interconnecting end sections of planar filter material sheet with each other by plastic material

摘要

The method involves interconnecting end sections (2A,2B) of planar filter material sheet (3) with each other by plastic material (7). The plastic material is heated in order to connect end sections of filter material sheet. The filter material sheet is made of cellulose material, glass, fiber blend fabric, polyester fiber, non-woven material and laminated paper. The plastic material is made of polyamide or polyester.
