Method of forming sieve unit for screening machine |
摘要 |
A screen unit for a screening machine comprises a screen layer which is bonded to a screen frame spanning an opening thereof. The screen layer is uniformly heated before such bonding is effected so that cooling after bonding generates a tension in the screen layer to allow it to have a trampoline or drumhead vibratile action. The tension is maintained by a reinforcing frame embedded in the frame body.
