A polishing machine for processing a fabric web having pile includes first and second heating cylinders, each of which has a diameter of 380 to 480mm. Each of the heating cylinders has three clockwise oblique grooves and three counterclockwise oblique grooves formed in an outer periphery thereof. Each of the oblique grooves has a "90 degree counterclockwise-rotated sigma" shaped cross section, which is used for both forward and backward rotation to impart orientation to the pile, or an "L" shaped cross section, which is used only for forward rotation. The clockwise oblique grooves alternate with the counterclockwise oblique grooves in an equal and symmetric configuration. Fabric webs of high quality can be processed with high productivity. |
