| 摘要 |
The invention provides for a sieve bend panel of synthetic plastics material which has a screening surface and a plurality of sides and fasteners fast with and projecting from two of its sides. The fasteners are complementary to each other so that fasteners on similar panels placed adjacent to the panel can engage with the fasteners on the two sides to thereby locate the panels side-by-side and to fasten the panels to each other.
