| 摘要 |
<p>The invention concerns a method for making a substantially mechanical screen cylinder (P) with centripetal or centrifugal flow relative to an axis (R), comprising rings (A) arranged in planes perpendicular to the axis of revolution and wires parallel (F) to the axis of revolution rigidly linked to the rings, uniformly spaced, to screen a product. The invention is characterised in that the assembling of a wire (F) on a ring (A) comprises a first operation which consists in positioning of said wire (F) in a corresponding notch (EN) of the ring and a second operation wherein the wire is welded on the ring by melting a shoulder (EP1) of the ring without external metal input. Said method enables to produce a screen cylinder having improved mechanical properties increasing its life span, and at reduced cost, as compared to standard mechanical baskets.</p> |
