[Abstract] The present invention describes a packaged highly compressed cuboidal bundle of filter tows without disturbing bulges or constrictions on the top and bottom surfaces of the bundle. The bale is characterized in that a) the bale has a packing density of at least 300 kg/m#+[3], b) the bale is completely wrapped by a mechanically self-supporting, elastic packaging material, wherein The seed material has one or more convective, air-tight connections, and c) the top and bottom faces of the bale are flat so that when the unopened bales are arranged on a horizontal plane, one completely covers the bale The plate of the bag can be pressed onto the top surface of the bale by an intermediate force of 100 N normal force, and inside the largest rectangle, at least 90% of the area of ​​the bale face above it has a maximum of about 40 mm from the plate. At a distance, the largest rectangle may be inscribed in a vertical projection of the bale on the extruded plate, the bale face lying inside the inscribed rectangle. One particularly suitable method for making such bales includes: a) preparing a filter tow in a compressed form, b) encapsulating the compressed filter tow with a packaging film, c) hermetically closing the packaging film, d) making The wrapped bales are loose. For this type of bale, it is avoided as far as possible that the packaging is cracked under internal pressure. It presents an ideal cubic shape so that, when transported, interference with the bulging of the bundle or the shrinkage of the output of the filter tow is ruled out as far as possible.
Sovereignty Items 1. A packaged, highly compressed, cuboidal bundle of filter filaments without disturbing bulges or constrictions on the top and bottom surfaces of the bundle, characterized by a. The bale has a packing density of at least 300 kg/m3, b. The bale is completely wrapped by a mechanically self-supporting, elastic packaging material, wherein this material has one or more convective, airtight connections, and c. The top and bottom surfaces of the bale are flat so that when the unopened bales are arranged on a horizontal plane, a flat panel that completely covers the bale can be squeezed through an intermediate force of 100 N normal force. On the top face of the bale, and within the largest rectangle, at least 90% of the area of ​​the bale face above it has a distance of up to about 40 mm from the plate, which can be inscribed in the bale. In a vertical projection on a pressed board, the bale face is located inside the inscribed rectangle.
