  • Publication number: 20040251268
    Abstract: A dispenser assembly for elongated objects, such as plant stakes, separates the objects individually from a store and pushes them into a substrate or pot plant. Individual separation takes place by means of a construction, adjoining the dispensing opening of the store, consisting of a central roller provided with a number of longitudinal grooves for accommodating the stakes and provided on either side, some distance therefrom, with discs for supporting stakes. If the stakes are skew or if they are inadmissibly bent, they drop off the roller and are not used further.
