Abstract
"PROCESSOS PARA FORMAR UMA TELA DE PRESSãO DE FIO EM FORMA DE CUNHA, E PARA FORMAR UMA TELA DE PRESSãO EM FORMA CILìNDRICA DO TIPO TENDO UMA MULTIPLICIDADE DE FIOS EM FORMA DE CUNHA ADJACENTES, E, CESTA DE TELA CILìNDRICA DE FIOS EM FORMA DE CUNHA". Processos para fabricar uma tela de pressão de fio em forma de cunha (10) e telas de pressão feitas por esse meio. Espaçadores (14) são integralmente formados sobre fios em forma de cunha (12) com os fios em forma de cunha agrupados lado a lado em um arranjo plano. Os fios em forma de cunha (12) são então flexivelmente presos um ao outro por um meio de união flexível tal como um fino filete de solda (20). Os espaçadores (14) são usados em vez de calcos discretos e limitam contra fios em forma de cunha vizinhos (12) para melhorar por esse meio a precisão dimensional das aberturas (48) formadas entre fios em forma de cunha adjacentes (12). O painel flexível é formado em uma forma cilíndrica por curvamento. Anéis de extremidade e suporte (84) são presos ao cilindro para formar uma cesta de tela de cilindro."PROCESSES FOR FORMING A WIRE-PRESSED WIRE PRESSURE SCREEN, AND FOR FORMING A CYLINDRICAL-PRESSURE SCREEN OF THE TYPE WITH ADJACENT Wedge-shaped WIRE MULTIPLICITY, AND, CYLINDRICAL WIRE-BASED SCREEN BASKET ". Processes for manufacturing a wedge-shaped wire pressure screen (10) and pressure screens made by this means. Spacers (14) are integrally formed on wedge-shaped wires (12) with wedge-shaped wires grouped side by side in a flat arrangement. The wedge-shaped wires (12) are then flexibly attached to each other by a flexible joining means such as a thin weld thread (20). Spacers (14) are used instead of discrete shims and limit against neighboring wedge-shaped threads (12) to thereby improve the dimensional accuracy of the openings (48) formed between adjacent wedge-shaped threads (12). The flexible panel is formed in a cylindrical shape by bending. End rings and support (84) are attached to the cylinder to form a cylinder mesh basket.
