ESLABONES COMPENSADORES PARA UN PROCESO CONTINUO DE CORTE PARA HOJAS ALARGADAS FLEXIBLES EN LA QUE UN BRAZO SESGADO (12) ES CONECTADO GIRATORIAMENTE EN SU EXTREMO A UN BRAZO CONDUCTOR (17) DONDE EL BRAZO CONDUCTOR (17) LLEVA EN SU FINAL CUCHILLAS DE DISCO (13) Y PIEDRAS AFILADORAS Y ESMERILADORAS PARA LAS CUCHILLAS, LOS EXTREMOS DEL BRAZO CONDUCTOR (17) SON CONECTADOS GIRATORIAMENTE CON DOS GRADOS DE LIBERTAD CON SUJECIONES (20,21), LAS CUALES, A SU VEZ ESTAN CONECTADOS A UN BRAZO DE CONTROL INSTALADO EXCENTRICAMENTE (30), EL ACOPLAMIENTO RESULTANTE EN COMPENSACION POR EL ANGULO SESGADO PERMITE OBTENER UN CORTE PERPENDICULAR AL MOVIMIENTO DE LAS HOJAS FLEXIBLES Y REDUCE LAS FUERZAS CENTRIFUGAS Y ELIMINA LAS CARGAS CENTRIFUGAS CICLICAS EN LOS SISTEMAS DE AFILAMIENTO DE CUCHILLAS. A novel compensating linkage for a continuous motion saw for elongated web plies wherein a skew arm is pivotally connected at its ends to a drive arm and where the drive arm at its ends carries disc blades and sharpening grinding stones for the blades, the ends of the drive arm being pivotally connected for two degrees of freedom with brackets which in turn are connected to an eccentrically mounted control arm, the linkage resulting in compensation for the skew angle to provide a cut perpendicular to the movement of the web plies. To prevent the hinge pins/bearings of the linkage wearing unevenly due to the constant reciprocating motion of the linkage member, a clutch is provided, which ensures that the hinge pins/bearings are constantly indexed forward.
