ABSTRACT:
For automatically drilling boreholes within halving joints and frame portions of lattice windows, ejecting glue into said boreholes and inserting dowels, units are proposed, which consist of three dowel inserting devices and three associated glue injecting devices each being operable individually and simultaneously, and which are arranged according to the borehole pattern within the face of a halving joint. For disposing the dowels in magazines and for inserting said dowels into the boreholes in a controlled manner changeable magazines are proposed the bottom of which is arranged above a dowel receiving head and the dowel discharge location is associated to the receiving locations of the dowel receiving head; in this position dowels are transferred into the recesses of the dowel receiving head and are arranged in the discharge position from which they are inserted by means of dowel ejectors into aligned boreholes of a workpiece.
