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.

Abstract: In a method intended particularly for securing an eraser and/or a sheath eiving it on a pencil in one continuous operation, it is provided that the pencils are conveyed through a work station and during that time, several sheaths or erasers and associated tools are simultaneously moved along with the pencils at the same speed as the pencils during a first work phase and are attached to the pencils during this time via the tools; in a second work phase, after the attachment process is completed, the tools are returned rapidly to the outset point, counter to the conveyance direction. The invention is furthermore directed to an apparatus for performing this method, which assures a very high operating speed. This apparatus includes at least one feeder device connected with a supply magazine for supplying one eraser or sheath to each of n feeder recesses having closed rear sides and being disposed beside one another in the feeder device.
