Abstract: A method is disclosed for applying thermal spray particles to a composite, wherein the method includes the steps of providing a composite that includes a thermally sensitive surface, and applying the thermal spray particles at a temperature that is high enough to cause a temperature-dependent change in the thermally sensitive surface of the composite. The temperature-dependent change improves adhesion between the thermal spay particles and the composite.

Abstract: An apparatus for doctoring a roll surface including a pivot bar adapted to b e mounted on a doctor back and which the pivot bar defines an upwardly projecting fulcrum. A first shelf projects forwardly beyond the fulcrum and a top plate pivotally supported on and projecting forwardly beyond the fulcrum overlies the first shelf. The top platen is hel d downwardly against the fulcrum. Blade support members are carried by and cooperate with the top plate to define forwardly open slots, which slots are configured and dimensioned t o receive a rear edge of a forwardly projecting doctor blade. The blade support members have rearwardly projecting second shelves underlying the first shelf and a loading mechanism is interposed between the first and second shelves for pivoting the top plate on the fulcr um in a direction urging the doctor blade against the roll surface.

Abstract: In a paper machine having a roll rotating about an axis extending in a cross machine direction, and having a doctor blade applied to the roll surface by a blade holder parallel to the axis and carried on a doctor back, an apparatus is provided for accommodating relative movement between the blade holder and the doctor back in the cross machine direction during mounting and removal of the blade holder. The apparatus comprises a rail fixed to the doctor back and extending longitudinally in the cross machine direction. A groove extends along the length of the guide rail. The groove has a bottom, a width measured between confronting sides, and a top defined by ledges projecting inwardly from the sides, with inner edges spaced one from the other to define a slot that underlies the blade holder and has a width narrower than the width of the groove. A plurality of shafts are spaced along the length of the blade holder and project downwardly through the slot and into the groove. First and second independently rotatable elements are carried by each of the shafts. The first rotatable elements are located in the slot and are dimensioned to contact the inner edges of the ledges, and the second rotatable elements are located in the groove and are dimensioned to contact the undersides of the ledges.

Abstract: En una maquina de papel que tiene un rodillo (12) que gira alrededor de un eje (A1) extendido en la direccion transversal a la maquina, y que tienen una cuchilla (14) de limpieza aplicada a la superficie del rodillo por un sujetador (16) de cuchilla paralelo al eje y llevado en la parte trasera (18) limpiadora, un aparato es provisto para adaptar el movimiento relativo entre el sujetador (16) de cuchilla y la parte trasera (18) limpiadora en la direccion transversal a la maquina durante el montaje y retiro del sujetador (16) de cuchilla. El aparato comprende un riel (42) fijo a la parte trasera (18) limpiadora y extendido longitudinalmente en la direccion transversal a la maquina. Una ranura (46) tiene un fondo (48), un ancho medido entre los lados (50) confrontado, una parte superior definida por resaltos (52) que se proyectan hacia adentro desde los lados (50), con bordes internos separados de cuchilla y que tiene un ancho mas estrecho que el ancho de la ranura (46). Una pluralidad de flechas (56) estan separadas a lo largo de la longitud del sujetador de cuchilla y se proyecta hacia abajo a traves de la ranura (54) y dentro de la ranura (46). Un primer (62) y segundo (64) elementos giratorios independientes son llevados por casa una de las flechas. Los primeros elementos (62) giratorios estan ubicados en la ranura (54) y tienen las dimensiones para hacer contacto con los bordes internos de los resaltos (52), y los segundos elementos giratorios (64) estan ubicados en la ranura (46) y tienen las dimensiones para hacer contacto con los lados inferiores de los resultados (52).

Abstract: A composite doctor blade comprises a steel support band (12) configured with (Wa) a width and thickness (Ta) suitable for mounting in a blade holder, with tensile and yield strengths suitable for a selected doctoring application. A wear resistant strip (14) of high speed steel is integrally joined to an edge of the support band. The wear resistant strip (14) has tensile and yield strengths higher than those of the support band (12), and has a hardness of between about 55 to 65 Rc.
