Abstract:
A process for manufacturing a sifting device having slit-shaped openings, the process comprising:forming a plurality of insets in a support element, and shaping the insets to comprise a first opening tapering to a predetermined depth and a second opening that expands from the predetermined depth;shaping a rod for insertion into the insets to be securely held in a position in the support element during subsequent manufacturing;inserting the rods to be substantially parallel in the insets, deforming the support element after insertion of the rods, such that the deformed state comprises an intended form, fixing the rods within respective insets by the deformation of the support element, and forming a filtering gap between the inserted rods; andpermanently bonding the rods in the insets with a high temperature bonding agent.
