Abstract

Patente de Invenção:<B>"COXIM DE ENCOSTO APERFEIçOADO PARA ESMERIL ROTATIVO"<D>. A invenção provê um coxim de encosto aperfeiçoado para um disco abrasivo adaptado para permitir observar a superfície enquanto está sendo esmerilhada, que compreende um coxim compressível e uma peça de suporte relativamente rígida laminada ao coxim que possui dimensões radiais menores do que o coxim nas partes da circunferência do coxim que estão propensas a entrar em contato com uma superfície inclinada durante o esmerilhamento. O resultado é que os discos abrasivos apoiados no coxim estão menos sujeitos a rasgamento em conseq³ência de tal contato.
