Abstract
The fluid filter (10) for fuel has a wound filter element (17) arranged in the housing (11) surrounded on its bottom end face (22) by a funnel-shaped welded-on cover cap (18). The cover cap (18) made of thermoplastic has an annular welding surface (25) which extends perpendicularly relative to the longitudinal axis of the filter and which is welded at least to the outermost complete turn (29) of the winding (17). An adhesive-free connection (32) between the wound filter element (17) and housing (11) thereby is formed. The preassembled wound filter element (17, 18) which can be handled easily is suitable for cold assembly on universal production lines and for different models.
