Abstract

PURPOSE: To obtain a means of continuous tanning and effective treatment of filter material by causing fine cracks to occur sufficiently to film-like resin on fiber of a filter material and also by making entire surface of the filter material shaggy.
CONSTITUTION: A set of tanning rolls 1 are provided with V-shape grooves on their entire surfaces both in the axial direction and circumferential direction at equal pitches and these rolls' surfaces are provided with such an appearance that sharp projections 7 on tips of rectangular pyramid are reguralrly arranged in the both axial and radial directions. A pair of top and bottom rolls 1 are assembled in such a manner that projections and indents are regularly engaged both in the axial and radial directions, and these rolls are both driven. In order to improve filtering efficiency of the material 18, this device is provided with a multi-stand of the rolls 1, equipped with pinch rolls 2 in front of the rolls 1 for feeding of the filter material and also provided with an uncoiler 3 in front of the pinch rolls 2. This device is also equipped with rolls 4 in the rear of the rolls 1 for rewinding of the filter material.
