  • Method of and apparatus for processing wires fastening compressed wastepaper block
    Patent number: 5105527
    Abstract: A compressed wastepaper block fastened by a plurality of wires is placed on a working table, and deformed or bent arcuately on the working table. After the compressed wastepaper block is bent, wires exposed in a concave created by the bent compressed wastepaper block are gripped by a presser/wire clamp, and a cutter is thrust substantially centrally into a convex side of the compressed wastepaper block which is opposite to the concave, thereby to cut off the exposed wires. The wires thus cut off are then removed from the compressed wastepaper block.
