 <Desc/Clms Page number 2> 

 Massgabe des Drucks des Kolbens im Zylinder sowie der Bildung des   Bleistifts vor   der   Düse, während sich   die Stange   20   dabei auf ihren   Führungen 18 veTstellt und   damit der Graphitkern mit der gleichen   Be-     wegungsgesehwindigkeit   aus dem Rohr 16 herausgezogen wird. mit der die Masse aus der Düse ausgestossen wird.

   Ist dabei der Kopf 21 der Stange 20 Über den ersten   Ständc. r 19 weggegwngen,   so findet der   Bleistiftkörper   eine Stütze auf dem Lager. 31 und kann auch hier neben dem Lager 31 mittels einer beliebigen. geeigneten Schneidvorrichtung in einzelne Bleistifte von gewünschter Länge zerschnitten

   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Bleistiften, dadurch gekennzeichnet, dass eine zur Bildung der Fassung für die Graphitmine benutzte plastische Masse unter Druck aus einer Formdüse ausgestossen. die ausgestossene Masse durch Wärme von ihrer Feuchtigkeit befreit und die Bewegung des ausgestossenen Massenendes zur gleichzeitigen Fortschaltung eines von ihr umschlossenen Graphitkernes nutzbar gemacht wird, wobei die Fortschaltgeschwindigkeit des Kerns gleich der   Ausstossgesehwindigkeit   der Masse ist.

  Method and apparatus for the production of pencils and. like
 EMI1.1
 

 <Desc / Clms Page number 2>

 Determination of the pressure of the piston in the cylinder and the formation of the pencil in front of the nozzle, while the rod 20 is positioned on its guides 18 and the graphite core is thus pulled out of the tube 16 at the same speed of movement. with which the mass is expelled from the nozzle.

   Is the head 21 of the rod 20 over the first Ständc. r 19 away, the pencil body finds a support on the bearing. 31 and can here in addition to the bearing 31 by means of any. suitable cutting device cut into individual pencils of the desired length
 EMI2.1
 can be repeated until the entire filling compound M of the cylinder 5 has been processed.



   PATENT CLAIMS:
1. A method for producing pencils, characterized in that a plastic compound used to form the socket for the graphite lead is ejected under pressure from a shaping nozzle. the ejected mass is freed of its moisture by means of heat and the movement of the ejected end of the mass is made usable for the simultaneous advancement of a graphite core enclosed by it, the advancing speed of the core being equal to the ejection speed of the mass.

Claims (1)

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass der Graphitkern in gleichachsiger Lage durch die Mündung der Ausstossdüse geführt und die den Kern umgebende Masse vor der Düsenmündung fortschreitend beheizt wird. 2. The method according to claim 1, characterized in that the graphite core is guided in an equiaxial position through the mouth of the discharge nozzle and the mass surrounding the core is heated progressively in front of the nozzle mouth. 3. Vorrichtung zur Durchführung des Verfahrens nach Anspiueh 1, gekennzeichnet durch einen die Masse enthaltenden Zylinder (5) mit einer Formdüse (8) an einem Ende, einem den Graphitkern tragenden, àxialenRohr (15) und einem die Masse durch-die Düse austreibenden Kolben (9), sowie einer von der ausgestossenen Masse betätigten Vorrichtung zur gleichzeitigen Fortschaltung des Graphitkerns durch die Düse hindurch mit einer der Ausstossgeschwindigkeit gleichkommenden Geschwindigkeit. EMI2.2 EMI2.3 3. Device for carrying out the method according to claim 1, characterized by a cylinder (5) containing the mass with a shaping nozzle (8) at one end, an axial tube (15) carrying the graphite core and a piston driving the mass through the nozzle (9), as well as a device actuated by the ejected mass for the simultaneous advancement of the graphite core through the nozzle at a speed equal to the ejection speed.
