Zusammenfassung: | This is a proposal for a powder application device P for manufacturing blanks of ther-moplastically workable semi-finished products for use as stiffening elements starting from a powder mixture containing a meltable plastic powder, which encompasses a powder container B open on the bottom as well as another one below it, and a perforated template L, which is arranged at a distance from it with one or several holes cut out. This template is characterised by the fact that powder container B is rigidly bonded with perforated template L and can be vertically lowered to an auxiliary carrier or a maximum distance of 5 mm to it. It is also lockable by means of horizontal striking plate L with a thickness slightly below the distance between powder container B and perforated template L on its lower end, whereby striking plate S can be moved on a horizontal level so that it alternately locks the lower end of powder container B and releases it again. |
