ABSTRACT:
A method and apparatus for securing an eraser to a pencil while deforming a heath mounted at one end on one end of the pencil and on the other end partially receiving the eraser, the sheath being subjected to deforming forces directed on the one hand toward the pencil and on the other toward the eraser. In order to provide a fastening of the sheath to the pencil and to the eraser, the pencil is guided along a path while at least the sheath is rolling, and the sheath is subjected to the deforming forces at least intermittently while rolling. The apparatus for performing the method comprises a pressure gap decreasing height between two parts that are movable relative to one another. The pressure gap is larger at the inlet and smaller toward the outlet than the outer diameter of the sheath in its underformed state.
