A creping system includes a Yankee dryer rotatable about its axis, a blade support mechanism which includes (a) a pair of guide rails (44, 46), (b) a fixed attitude linear bearing engaging and translatable along each of the guide rails, each fixed attitude linear bearing being mounted on a block (50) and (c) a com- bination linear-rotary bearing being carried by each block, the axis of each combination line- ar-rotary bearing being parallel to the genera- tors of the surface of the Yankee dryer and colinear with the axis of the other combination linear-rotary bearing. A stub shaft (20A) en- gages each combination linear-rotary bearing, each stub shaft being translatable along, and rotatable about, the axis of its respective com- bination linear-rotary bearing. A blade holder (12A) is mounted between the stub shafts, and a blade mounted on the blade holder for en- gagement with the surface of the Yankee dry- er. The blade support mechanism allows the creping angle of the blade to be adjusted and maintained within a desired range by allowing adjustment of the creping blade angle to compensate for changes in creping angle due to flexure of the blade and flan k wear on the blade. This adjustment is permitted while allowing the blade holder (18) to be (a) translated in a direction parallel to the generators of the surface of the Yankee dry- er, (b) rotated about the axis of the stub shafts, and (c) urged inwardly toward, or outwardly away from, the surface of the Yankee dryer.
