<p>The present invention refers to a packing method for a filter tow bale in which filter tow is compressed and packed with a compressing device including an upper press base and a lower press base to manufacture the filter tow bale, comprising steps of:
(a) setting a top-side film on a compression surface of the upper press base, setting a bottom-side film on a compression surface of the lower press base, and feeding the filter tow between the compression surface of the upper press base and the compression surface of the lower press base;
(b) compressing the filter tow with a pressure of 100 t/m 2 or more by said upper press base and said lower press base so as to form a pressed bale, the pressure of 100 t/m 2 or more being applied and maintained for 5 to 15 minutes;
(c) packaging the pressed bale with the top-side film and the bottom-side film and then sealing the top-side film and the bottom-side film to each other in an airtight state;
(d) increasing a distance between said upper press base and said lower press base of the steps (b) and (c) by a range of 50 to 250 mm so as to expand the pressed bale; and
(e) releasing the compression pressure applied on the pressed bale after the sealing.</p> |
