摘要： A screen is described for use in a vibrating machine for separating solids from liquid material, comprising woven wire cloth of orthogonal warp and weft wires, tensioned and bonded to a support structure defining at least one rectangular opening across which the cloth extends. The orientation of the cloth is chosen so that the warp wires extend across the width (i.e. shorter dimension) of the or each opening. A method of manufacturing two screens side by side in a jig involves laying a length of woven wire cloth across two rectangular frames laid side by side in the jig with longer edges thereof abutting, and orientating the cloth so that the warp wires extend continuously across the two screens. The cloth is bonded to the frames after which it is severed along the join and surplus cloth is trimmed away from the edges of the frame. If the cloth has a square mesh and the warp wires are of greater cross section than the weft wires, the warp wires will extend across the width of the frame, and if the cloth has a rectangular mesh, the greater number of warp wires per unit length will also extend across the width of the frame, so that in each case warp wires will resist in use the stresses across the width of the central region of the or each opening.
摘要翻译：描述了一种用于振动机器的屏幕，用于从液体材料分离固体，包括正交经线和纬线的编织线布，其被张紧并结合到支撑结构，所述支撑结构限定布延伸穿过的至少一个矩形开口。选择布的取向使得经线延伸穿过该开口或每个开口的宽度（即较短的尺寸）。在夹具中并排制造两个屏幕的方法包括将一定长度的编织线布跨过夹具的两个矩形框架并排放置，其中较长的边缘邻接，并使织物定向延伸穿过两个屏幕。布被粘合到框架上，沿着连接件被切断，多余的布被从框架的边缘修剪掉。如果布具有方形网格，并且经线比纬线更大的横截面，则经线将延伸跨越框架的宽度，并且如果布具有矩形网格，则每单位更多的经线长度也将延伸跨越框架的宽度，使得在每种情况下，经线将在使用中抵抗穿过该开口或每个开口的中心区域的宽度的应力。
