ABSTRACT:
The invention provides a process for compressing filament tows to bales and packaging them with flexible packaging material and reinforcing strips by means of a novel baling press, the press ram of which is divided into a core ram (4) and a surrounding outer ram (5), so that the relative positions of these two rams may be varied during the compression operations. By means of fingers (10), the collar of packaging material formed on compression can be bent in such a manner when lifting the outer ram (5) that on renewed lowering of the outer ram (5) strip-reinforcement is not hindered any more.
Bales of high unit weight are obtained which allow trouble-free processing of the filament tows.
