Abstract
1501669 Grinding SCOTT PAPER CO 12 May 1975 19797/75 Heading B3D A method of forming a predetermined crown contour from end to end on the exterior surface of a drier drum 24 comprises rotating the drum about its axis 32, contacting the surface with a rotating grinder 17 movably mounted on a carriage 8 and positioned with respect to the axis 32 by a cam 27 having a contour with a predetermined relationship to the predetermined crown contour to be formed, traversing the carriage from end to end of the drum, and rotating the cam in proportion to the movement of the carriage to cause the grinder to move in a path having the shape of the predetermined crown contour. In apparatus for carrying out the method, a bed 9 having a flat way 21 and V-way 22 is mounted on the floor adjacent the drum 24 which is mounted on a shaft carried by bearings 6 for rotation about the axis 32. The carriage 8 is movable along the bed by a motor 25 driving a pinion 24 engaging a rack 26. A grinder 7 has a base 11 which is mounted for movement about a pivot 19 on the carriage and is formed with a guideway 10 along which a grinder frame 12 is adjustable by adjustment means 14, the frame rotatably supporting a contact wheel 15, driven by a motor 18, and a backstand wheel 16, an abrasive belt 17 being entrained around the wheels. The grinder 7 is movable about the pivot 19 as the carriage is moved along the bed to form the contour on the drum by the engagement of a follower 31 on the grinder with the cam 27 which is rotated by a worm drive 28, 29, from the rack 26. The contour of the contact wheel is convex and the shape of the cam 27 depends on the contour to be produced on the drum and the movement of the point of contact along the contour of the contact wheel as it moves from the centre of the drum to the ends (Fig. 3). The cam is produced on a computercontrolled milling machine fed with the necessary data. The periphery of the contact wheel may be resilient. In another embodiment, the abrasive belt assembly 15, 16, 17 is replaced by a rigid grinding wheel.
