20150021240 | WOVEN WIRE SCREENING AND A METHOD OF FORMING THE SAME - A woven wire screening for use in classifying material flowing therethrough and a method of forming the same. The woven wire screening includes a plurality of warp wires and a plurality of weft wires. The plurality of warp wires and the plurality of weft wires are interwoven to form an integral wire cloth having a plurality of openings for permitting material to be classified to flow through the openings. The integral wire cloth includes an upper screening surface configured to enhance the tumbling action of product impacting the upper screening surface to improve throughput of the woven wire screening. | 01-22-2015 |
20140284185 | WOVEN WIRE CONVEYOR BELT AND A METHOD OF FORMING THE SAME - A woven wire conveyor belt having a plurality of spiral wires and a plurality of connecting wires operably associated with the plurality of spiral wires to form a conveying surface with a plurality of openings formed therein. Each of the plurality of spiral wires has a first side wall and a second side wall that are substantially flat. The connecting wires can be crimped or straight wires. The spiral wires can be left spiral wires, right spiral wires or a combination of left and right spiral wires. The spiral wires and the connecting wires are preferably formed from round wire. Preferably, the woven wire conveyor belt is an endless belt. The conveyor belt can be a balanced weave wire belt, a double weave wire belt, a rod reinforced weave wire belt, a chevron weave wire belt, a double balance weave wire belt, and a single weave wire belt. | 09-25-2014 |
20140231316 | SCREENING FOR CLASSIFYING A MATERIAL - A screening or screen for use in classifying material. The screening includes a plurality of warp screening elements. Preferably, the plurality of warp screening elements is a plurality of warp wires. The plurality of warp screening elements includes a first warp screening element having a plurality of horizontal undulations. The plurality of warp screening elements further includes a second warp screening element. Preferably, one of the first warp screening element and the second warp screening element is a shaped wire having two substantially flat sidewalls. At least one retaining member is operably associated with the plurality of warp screening elements to form an integral screen segment having a plurality of openings for permitting material to be classified to pass through the openings. The first warp screening element has a cross-sectional height or shape different from the cross-sectional height or shape of the second warp screening element. | 08-21-2014 |
