Abstract
A separation component for a filter element has a web-shaped support body with a top rim and a bottom rim. A web-shaped separator body covers a side face of the support body completely or partially. Support body and separator body are wound to a spiral shape with axially successive turns. The support body has a connecting fold at the top rim and at the bottom rim, respectively. The connecting folds engage each other in the axially successive turns of the spiral shape. The separation component can be manufactured by placing a web-shaped separator body onto a web-shaped support body and by winding support body and separator body to a spiral shape. During winding, a connecting fold at a top rim of a turn of the spiral shape and a connecting fold at a bottom rim of an axially successive turn are brought into engagement with each other.
