ABSTRACT:
A process for production of conical filter elements, in particular slotted tube filter elements, includes forming a support structure of a plurality of support rods around which is wound at least one wire profile in individual turns. Slots are left clear in the wire profile through which a fluid may pass. The wire profile is, at least in part, rigidly connected to the support rods and is enclosed in a screen grid. The screen grid, at least in part, rests against the wire profile, follows to the same extent the conical path of the filter element, and is provided on its ends with end components. Since the conical screen grid is in the form of a one-piece pull-on part fitted on the support structure and since the pull-on part is designed to be longer than the support structure, after the screen grid has been pulled onto the support structure, at least one projecting length of the screen grid may be separated for precision fitting and is connected to the respective end component of the filter element. The screen grid may be produced integrally with the remaining filter element in advance of the connection process and subsequently pulled onto the support structure with wire profile like a stocking.
