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. The feeder device is coupled via a cam drive with the drive mechanism of the transporting device in such a manner that the method step provided in accordance with the intention can in fact be performed.
