Description
linders 10 in Achsrichtung auf der Welle 7 verschiebbar ist, sind auf dem Umfang verteilt Hebel 11 angelenkt, die in Richtung auf die Aufbautrommel 1 verschwenkt werden können. Die Schwenkbewegung wird durch Aufblähen eines ringförmigen Blähkörpers 12 erzeugt. Auf den äußeren Flanken der Hebel 11 ruht ein ebenfalls ringförmiger Blähkörper 13, der beim Abwinkein der Karkaßgeweberänder mit einem Druckmittel beaufschlagt wird und die Karkaßgeweberänder um die Wulstkerne 8 herumlegt. Darüber hinaus ist der Schiebekörper 9 mit Hilfe eines Ringzylinders 14 relativ zur Aufbautrommel 1 verdrehbar, wodurch die auf dem Blähkörper 13 liegenden Karkaßgeweberänder eine Abwicklung in Umfangsrichtung erfahren. Außerhalb des Schiebekörpers 9 ist ein Klemmglied 15 angeordnet, das mit Hilfe eines Zylinders 16 axial verfahrbar ist. Das Klemmglied 15 besteht aus einem U-förmigen zur Welle 7 hin geöffneten Klemmringhalter 17 mit einem darin befindlichen in radialer Richtung zur Trommelwelle beweglichen Klemmring 18. Dieser ist von einem Druckmittelraum 19 umgeben, in den ein Druckmittel einführbar ist, wodurch sich der Klemmring 18 in seinem Durchmesser verkleinert, d. h., sich radial auf die Aufbautrommel 1 zu bewegt und die Karkaßgewebelage 6 einklemmt. An der zur Aufbautrommel 1 gerichteten Seite des Klemmgliedes 15 ist eine im wesentlichen winkelförmige Halterung 21 für den Wulstkern 8 mit Hilfe eines Distanzringes 20 in einem veränderbaren Abstand angebracht.Linders 10 is displaceable in the axial direction on the shaft 7, levers 11 are articulated distributed on the circumference, which can be pivoted in the direction of the building drum 1. The pivoting movement is generated by inflating an annular inflatable body 12. On the outer flanks of the levers 11 rests a likewise ring-shaped inflatable body 13, which when bending the carcass tissue edges with a Pressure medium is applied and the carcass fabric edges around the bead cores 8. About that In addition, the sliding body 9 can be rotated relative to the building drum 1 with the aid of a ring cylinder 14, whereby the carcass fabric edges lying on the inflatable body 13 develop in the circumferential direction Experienced. Outside of the sliding body 9, a clamping member 15 is arranged, which with the help a cylinder 16 is axially movable. The clamping member 15 consists of a U-shaped shaft 7 towards open clamping ring holder 17 with one located therein in the radial direction to the drum shaft movable clamping ring 18. This is surrounded by a pressure medium chamber 19 into which a pressure medium is insertable, whereby the clamping ring 18 is reduced in diameter, d. i.e., radially the building drum 1 is moved and the carcass fabric layer 6 is pinched. On the building drum 1 facing side of the clamping member 15 is a substantially angular bracket 21 for the Bead core 8 attached with the help of a spacer ring 20 at a variable distance.
Zu Beginn der Konfektionierungsarbeiten ist, wie in F i g. 1 erkennbar, das Klemmglied 15 in die äußere Endstellung zurückgefahren. Es folgt das Auflegen der Karkaßgewebelage 6 (Fig. 2) auf die Aufbautrommel 1, wobei der Rand der Karkaßgewebelagen 6 im wesentlichen auf dem Blähkörper 13 liegt. Alsdann wird mit Hilfe des Zylinders 16 das Klemmglied 15 in Richtung auf die Aufbautrommel 1 gefahren. Der Klemmring 18 wird mit einem Druckmittel beaufschlagt und gleichzeitig der Blähkörper 13 in geringem Maße unter Druck gesetzt sowie dadurch der Rand der Karkaßgewebelage 6 eingeklemmt. Mit Hilfe des Ringzylinders 14 wird der Schiebekörper 9At the beginning of the assembly work, as shown in FIG. 1 can be seen, the clamping member 15 in the outer End position retracted. The carcass fabric layer 6 (FIG. 2) is then placed on the building drum 1, the edge of the carcass fabric layers 6 lying essentially on the inflatable body 13. Then the clamping member 15 is moved in the direction of the building drum 1 with the aid of the cylinder 16. The clamping ring 18 is acted upon by a pressure medium and at the same time the inflatable body 13 in Pressurized to a small extent and thereby pinched the edge of the carcass fabric layer 6. With With the aid of the ring cylinder 14, the sliding body 9
xo um ein bestimmtes Winkelmaß relativ zur Aufbautrommel 1 verdreht, wodurch der Rand der Karkaßgewebelage 6 in Umfangsrichtung abgewinkelt wird. Gleichzeitig erfährt der Schiebekörper 9 durch Beaufschlagen des Zylinders 10 mit einem Druckmittel eine von der Aufbautrommel 1 wegführende Axialbewegung (F i g. 3).xo by a certain angular dimension relative to the building drum 1 twisted, whereby the edge of the carcass fabric layer 6 is angled in the circumferential direction. At the same time, the sliding body 9 is exposed to a pressure medium when the cylinder 10 is pressurized an axial movement leading away from the building drum 1 (FIG. 3).
Alsdann erfolgt das Vergrößern des Durchmessers der Aufbautrommel 1 mit Hilfe des Blähkörpers 3, wobei gleichzeitig der Klemmring 18 durch Freilassen des Druckmittels zurückbewegt wird und so die Karkaßgewebelage 6 der Bewegung der Aufbautrommel 1 nachkommen kann (F i g. 4). Ohne weiteres Verschieben des Klemmringes 15 kann der Wulstkern 8 nun an der vorgesehenen Stelle abgesetzt werden. Das Klemmglied 15 fährt jetzt in die äußere Endstellung zurück. Nun wird der Blähkörper 13 mit einem Druckmittel beaufschlagt, wodurch die Karkaßgeweberänder zur Trommelmitte hin bewegt werden (F i g. 5). Die Blähkörper 12 werden ebenfalls mit einem Druckmittel beaufschlagt und schwenken die Hebel 11 auf die Aufbautrommel 1 zu. Die Karkasse wird dann, nachdem die Vorrichtungsteile in die Ausgangsposition zurückgefahren sind, abgenommen. The diameter of the building drum 1 is then increased with the aid of the inflatable body 3, at the same time the clamping ring 18 is moved back by releasing the pressure medium and so the Carcass fabric layer 6 can follow the movement of the building drum 1 (FIG. 4). Just like that Moving the clamping ring 15, the bead core 8 can now be deposited at the intended location. The clamping member 15 now moves back into the outer end position. Now the inflatable body 13 is with applied to a pressure medium, whereby the carcass fabric edges are moved towards the center of the drum (Fig. 5). The inflatable bodies 12 are also acted upon by a pressure medium and pivot the levers 11 towards the building drum 1. The carcass is then after the device parts in moved back to the starting position.
