Apparatus for the manufacture of dowels, preferably wooden dowels

摘要

With the apparatus intended for the manufacture of wooden dowels, it is possible to manufacture, in a cost-effective manner, dimensionally accurate dowels which, in addition, can be inserted considerably more easily into the cylindrical bores of the parts to be joined. The dowel rods provided for the manufacture of the dowels are individually notched over the intended dowel length in a notching station arranged above a revolving conveying device and are cut at the deepest point of the notches. For this purpose, the notching strips of the notching station are arranged inclined in the conveying direction, there being arranged, at the end of the notching strips, in each case a knife which is guided beyond the lower boundary of the notching strips and has a conically extending cutting edge. The through-passage of the dowel rods takes place by means of frictional engagement with the conveyor belts. By cutting the dowel rods, no material losses occur. After the cutting, the dowels have a bevel at their ends owing to the notches which have been made.
