Abstract
A filter element includes a filter cylinder whose outer side rests against a fluid-permeable supporting tube (). The inside () of the filter cylinder can be flown through by the fluid to be filtered. The filter cylinder is formed by a filter mat web. The filter mat web has a series of folds () that rest against one another at least in areas. Both ends of the filter mat web are joined to one another at a junction () to form an annular body (). The filter element includes a device that acts upon the junction () to prevent, in the area of the junction (), a bulging of the folds () caused by the flow of the fluid.
