Drawing frame, particularly Kosovo environmental protection agency-drawing frame for distorting fiber assembly, has central point of larger diameter lower roller, which is arranged between central points of smaller diameter lower rollers

摘要

The drawing frame (1) has a central point (23) of a larger diameter lower roller (3), which is arranged between the central points (22,24) of the smaller diameter lower rollers (2,4) at the side of an imaginary connecting line (17). A distance (A) of the central point of the larger diameter lower roller is provided between 2 millimeter to 15 millimeter at an imaginary connecting line. The larger diameter lower roller is made of steel and has a surface coating.
