Die Erfindung betrifft in erster Linie ein Verfahren zum Stapeln und Zuführen von auf Länge geschnittenen, unvulkanisierten Laufstreifen zur Aufbautrommel einer Reifenaufbaumaschine, bei dem die Laufstreifen unter Zwischenlegen einer Folie gestapelt und mit der Folie der Aufbautrommel zugeführt werden und die Folie kurz vor der Aufbautrommel von den Laufstreifen abgezogen wird. Bei der Herstellung von Fahrzeugluftreifen sind Maschinen bekannt, denen beiderseits in Kautschuk gebettete Gewebestreifen zugeführt werden, die von Haspeln abgezogen werden. Zusammen mit den Gewebestreifen sind Schutzstreifen auf die Haspel aufgewickelt, damit die Gewebestreifen nicht aneinander festkleben.The invention relates primarily to a method for stacking and feeding cut to length, unvulcanized tread for the building drum of a tire building machine, in which the Treads stacked with a film in between and fed with the film to the building drum and the film is pulled off the tread just before the building drum. In the preparation of Machines are known of pneumatic vehicle tires which have fabric strips embedded in rubber on both sides are fed, which are withdrawn from reels. Together with the fabric strips protective strips are wound onto the reel so that the fabric strips do not stick to one another.

Beim Zusammenbau von Reifen wurden bisher entweder die dazu benötigten Teile von Rollen auf die Aufbaumaschine übergeführt und dort abgeschnitten oder zurechtgeschnittene Stücke aus Transportbehältern entnommen und von Hand auf die Aufbaumaschine gebracht.In the past, when assembling tires, either the parts required for this were placed on the rollers Construction machine transferred and there cut off or cut to size pieces from transport containers removed and placed on the assembly machine by hand.

Mit der Erfindung wird die Aufgabe gelöst, die Vorteile der kontinuierlichen Fertigung von Reifen mit den Vorteilen der Stapelung und Lagerung zurechtgeschnittener Reifenteile auf Paletten oder in ähnlichen Behältern zu vereinigen. Für das obengenannte Verfahren wird nach der Erfindung vorgeschlagen, daß die Laufstreifen senkrecht aufeinandergestapelt werden, wobei zwischen je zwei Laufstreifen zwei feste glatte Folien gelegt werden, und daß von oben beginnend nacheinander die jeweils obere Folie, unter Gleiten auf der unteren Folie, mit dem daraufliegenden Laufstreifen abgezogen wird. Die Folien zur Durchführung des Verfahrens sind erfindungsgemäß dadurch gekennzeichnet, daß zwei aufeinanderliegende Folien an der der Abzugseite entgegengesetzt liegenden Seite in einer Schlaufe ineinander übergehen und aus einem Stück bestehen. Es ist von Vorteil, daß die unteren Folien mit den oberen Folien der darunterliegenden Doppellage durch Schlaufen unter Einbettung aller Laufstreifen zwischen einer durchgehenden Folie verbunden sind.The invention solves the problem, the advantages of the continuous manufacture of tires with the advantages of stacking and storing cut tire parts on pallets or in to unite similar containers. For the above method it is proposed according to the invention, that the treads are stacked vertically, with between two treads two firm, smooth foils are placed, and that, starting from the top, one after the other the upper foil, while sliding on the lower film, is pulled off with the tread on it. The slides for carrying out the method are characterized according to the invention in that two superimposed Foils inside one another in a loop on the side opposite the draw-off side pass over and consist of one piece. It is advantageous that the lower foils with the upper foils the underlying double layer by loops with embedding of all treads between one continuous foil are connected.

Eine dem Verfahren entsprechende Maschine zum Aufbau der Reifen kann etwa so ausgebildet sein, daß sie ein Ende einer als endloses Band ausgebildeten Folie faßt und die Schlaufen aufzieht, so daß nacheinander im Takt ein Laufstreifen nach dem anderen der Maschine zugeführt wird. Der Laufstreifen gleitet in die Maschine hinein, die Folie wird bei der Trennung von dem Laufstreifen auf eine Rolle aufgewickelt und kann wieder verwendet werden.A machine corresponding to the method for building the tires can be designed as follows: that it grips one end of a film designed as an endless belt and pulls the loops open so that one tread after the other is fed to the machine one after the other. The tread slides into the machine, the film is on a roll when it is separated from the tread wound up and can be used again.

Maschine, die Aufbautrommel 2, deren Motor 3, die Rolle 4 zum Aufwickeln der ablaufenden Folie, der Antriebsmotor 5 für die Rolle 4, die Ablaufrolle 6, die Rollenbahn 7 und eine nicht näher beschriebene Einrichtung 8, die zur Ausrichtung der auflaufenden Laufstreifen dient, sind Hauptbestandteile der Anlage.Machine, the building drum 2, its motor 3, the roller 4 for winding up the running film, the Drive motor 5 for the roller 4, the run-off roller 6, the roller conveyor 7 and a device not described in detail 8, which are used to align the accruing tread are the main components of the system.

Die Laufstreifen 9 sind in einer Palette 10 aufgestapelt, und zwar so, daß sie nicht miteinander in Berührung kommen können. Hierzu ist jeweils eine Schlaufe 12 der Folie 11 zwischen je zwei Laufstreifen 9 eingelegt. Das Ende 13 der Folie 11 ist an der Rolle 4 befestigt.The treads 9 are stacked in a pallet 10 in such a way that they do not come into contact with one another can come. For this purpose, there is a loop 12 of the film 11 between each two treads 9 inserted. The end 13 of the film 11 is attached to the roll 4.

Wenn die Rolle 4 von dem Antriebsmotor 5 angetrieben wird, wickelt sie die Folie 11 auf. Jeweils der oberste Lauf streif en 9 wird hierbei über die Ablaufrolle 6 auf die Rollenbahn? gefördert, die Folie 11 trennt sich von dem Laufstreifen 9, der Laufstreifen 9 wird gegen die Aufbautrommel 2 angeschoben und die nächste Schlaufe 12 der Folie 11 wird aufgezogen und auf die Rolle 4 aufgewickelt.When the roll 4 is driven by the drive motor 5, it winds up the film 11. In each case the The top running strip 9 is here on the roller conveyor 6 on the roller conveyor? promoted, the slide 11 separates from the tread 9, the tread 9 is pushed against the building drum 2 and the The next loop 12 of the film 11 is pulled up and wound onto the roll 4.

Inzwischen hat die Aufbautrommel 2 den aufgelaufenen Laufstreifen 9 übernommen und zur Verarbeitung gebracht.In the meantime, the building drum 2 has accumulated Tread 9 taken over and brought for processing.

Die Rollenbahn 7 ist wieder frei für den nächsten Laufstreifen 9, den die Folie 11 herantransportiert.The roller conveyor 7 is free again for the next tread 9, which the film 11 transports.
