    摘要： A method and apparatus for cleaning the surface of a backing roll in a coater or a calender roll. The roll is cleaned by injecting steam from a steam injection chamber against the roll surface at a 15.degree. angle counter to the rotational direction of the roll. Steam impinging on the surface performs effective removal of accumulated dirt and the detached dirt is carried away on the web without a deleterious effect on the quality of the web. Steam injected against the roll is vacuumed away from the roll surface via a suction chamber, whereby the cleaning steam is prevented from escaping to the surroundings.

    摘要： A rolling device or roller mill having a controlled-deflection roll possessing a stationary roll support or carrier mounted in a frame of the rolling mill. A tubular roll shell is rotatable about the roll support and bears thereon by means of at least one bearing or support element. The roll shell is provided at its ends with guide members which are rotatably mounted in the roll shell and which are guided on the roll support in the direction of the pressing or disengaging movement of the roll shell. The controlled-deflection roll is equipped with a scraper device having a scraper blade which, during operation, is in contact with the outer surface of the roll shell, the scraper device being rotatably mounted on the frame. At least one of the guide members has a disengaging or lift-off element which, when the roll shell performs a disengaging or lift-off movement from the operative position, abuts a part of the blade support or carrier and raises the blade off the surface of the roll shell.

    摘要： A DOCTOR IS DISCLOSED HAVING A PIVOTABLE DOCTOR BACK PARALLEL TO AND SPACED FROM A ROLL OF A PAPER MAKING MACHINE. A BLADE CARRIED BY A BLADE HOLDER IS CONNECTED TO THE BACK BY RESILIENT MEANS COMPRISING A FIRST CANTILEVER CONNECTED TO THE DOCTOR BACK AND PROJECTING AWAY FROM THE ROLL, AND A SECOND CANTILEVER CONNECTED TO THE FREE END OF THE FIRST CANTILEVER WITH THE FREE END OF THE SECOND CANTILEVER PROJECTING TOWARD THE ROLL. THE SECOND CANTILEVER SUPPORTS ON THE FREE END THEREOF A BLAND HOLDING ASSEMBLY TO CARRY THE BLADE. TEH BLADE IS THUS CARRIED BY A DOUBLE CANTILEVERED RESILIENT MEANS FOR SUPPLEMENTING THE RESILIENCY OF THE BLADE FOR CONTOUR FOLLOWING ENGAGEMENT OF THE BLADE WITH THE ROLL.

    摘要： A DOCTOR IS DISCLOSED HAVING A PIVOTABLE DOCTOR BACK PARALLEL TO AND SPACED FROM A ROLL OF A PAPER MAKING MACHINE. A BLADE CARRIED BY A BLADE HOLDER IS RESILIENTLY CONNECTED TO THE DOCTOR BACK BY A THIN PLATE OF SUBSTANTIAL WIDTH AND SUFFICIENT LENGTH RELATIVE TO ITS THICKNESS SO AS TO BE RESILIENT AND SUPPLEMENT THE RESILIENCY OF THE BLADE FOR IMPROVED CONTOUR FOLLOWING AND PRESSURIZED SCRAPING OF THE ROLL. THE THIN PLATE, MADE UP OF SEVERAL SEGMENTS ABUTTING EACH OTHER ALONG EDGES NORMAL TO THE ROLL, EXTENDS THE FULL WIDTH OF THE ROLL AND COVERS THE SPACE BETWEEN THE ROLL AND DOCTOR BACK. THE BLADE HOLDER COMPRISES SEGMENTS WHICH OVERLAP THE PLATE SEGMENT, WITH ADJACENT BLADE HOLDER SEGMENTS HELD IN ALIGNMENT FOR BLADE INSERTION AND REMOVAL, BY AN OVERLAPPED PLATE SEGMENT.
