Abstract
Restrained bales are formed for transporting high-bulk, crosslinked cellulose fiber in a reduced volume. A limited amount of force is used in compressing the fiber into the bales so that the fiber is not damaged. The limited amount of force used allows the bale, when restraints are released, to expand to about twice its restrained volume. Fiber damage is further minimized by limiting the amount of compression to the minimum required so that a transport container is completely filled to its volume and payload capacities.
Claims2
A method of applying a force to compress a volume of high-bulk, crosslinked cellulose fiber the method comprising:
- introducing high-bulk, crosslinked cellulose fiber at a first density of about 0.008 g/cc into load hopper connected to a bale chute wherein the load hopper funnels the high-bulk fiber into the bale chute;
- and
- applying a pressure of no more than about 42.7 kgs/cm.sup.2 to compress the fiber into the form of a bale and to extrude the bale through the bale chute, the compressed fiber being at a second density of from about 0.1 g/cc to about 1.0 g/cc.
