Abstract
Disclosed is a packed, highly compressed cuboid-shaped filter tow bale, the top side and bottom side of which are free from noisome curvatures or constructions. A method for producing the bale comprises the following: (a) filter tow is supplied in a compressed form: (b) the compressed filter tow is enveloped in a wrapping; (c) the wrapping is closed in an airtight manner; and (d) the wrapped bale is relieved of the load. The wrapping of such a bale is largely prevented from bursting as a result of the prevailing internal pressure.
