发明名称 Vibratory screening system and screen therefor
摘要 A screen having a frame, three screen cloth layers and a laminating solidified layer with perforations therethrough. The screening layer of the screen cloth is typically of the finest mesh with increasing coarseness to the support mesh. The solidified layer is positioned by placement on the supporting mesh where it is fused to impregnate through each of the screen layers to form surfaces on either side of the lamination. A heat press is employed to so configure the solidified layer. A nonstick sheet between the screening mesh and the heat press molds texture into the surface of the solidified layer for reduced slippage of material being screened on the assembly. The screen lamination is stretched and bonded to a screen frame.
