A method and a system for the manufacture of a plastics filling material

True zero-clearance cutting on a commercial scale is provided via a cutting area including a sacrifice material that is relatively softer than the cutter. One example is a cutting system which is capable of cutting a material such as, for example, tape or paper, into a fiber or powder. The cutting system includes a cutting blade, typically a rotary cutter, and a sacrificial plate or round bar contacting the cutting blade. The contacting portion has a zero clearance during the cutting operation. A metering mechanism is also provided which is capable of metering the material at a predetermined rate to the cutting blade. A mechanism is also provided for incrementally moving the sacrificial blade towards the cutting blade to ensure that the zero clearance is maintained between the cutting blade and the sacrificial plate, even when the sacrificial plate begins to wear down due to usage. Also, destruction of the material is further enhanced by advantageous strategic patterning of cutting edges on a rotary cutter, and further by secondary shredding features. Systems are provided for reducing to-be-destroyed paper and other relatively-thin planar materials to a dust or powder-size.

Process for preparing water-soluble polymer gel particles

ABSTRACT A novel process for preparing particles of polymer gel prepared by polymerizing an aqueous solu-tion of water-soluble vinyl monomers which comprises breaking the polymer gel into particles with a breaker device wherein the gel is cut into strips by a pair of rollers having a plurality of annular projections or grooves on their surfaces, the rollers rotating in the opposite direction to each other to engage to each other and to cut off the gel fed between the rollers, and the strips are then cut into particles by a combi-nation of a fixed cutting blade and a rotating cutting blade. The obtained gel particles are further pulver-ized into fine round or spherical particles in a ver-tical type cutter comprising at least one vertically fixed cutting blade and a rotary cutting blade ar-ranged rotatably and vertically, a clearance being provided between an edge of the rotary cutting blade and an edge of the fixed blade.
