Abstract

The connection point of mutually adjoining band proportions of the band, especially the conveyor band made of PTFE glass fabric, has, on the mutually confronting end faces of the band portions, oppositely directed bevels with oblique faces confronting one another. The oblique faces are connected to one another, preferably by welding, an intermediate layer being arranged between the oblique faces. When such conveyor bands are used, for example in the textile industry, the described design of the connection point avoids imprints on the conveyed material and an accumulation of dust and dirt at the connection point. It is advantageous, furthermore, that, during a cleaning of the band by means of scrapers, a premature wear caused by a constant butting of the scraper against the connection point is avoided.

Description

Band, insbesondere Transportband aus PTFE-Glasgewebe, mit einer Belt, in particular conveyor belt made of PTFE glass fabric, with a

Verbindungsstelle von aneinander anschließenden Bandabschnitten Die Verbindungsstellen von Bandabschnitten sind vielfach überlappend ausgebildet oder weisen eine unterlegte, gestoßene Naht auf. Dies hat an der Verbindungsstelle Verdickungen zur Folge, welche in vielen Anwendungsbereichen der Transportbänder Abdrücke auf dem Transportgut zur Folge haben. Dieser Nachteil ergibt sich speziell bei Transportbändern aus Polytetrafluoräthylen (sog. "PTFE") Glasgeweben. Bei Einsatz derartiger Transportbänder beispielsweise in der Textilindustrie bei der automatischen Fertigung von Hemdkragen haben die Verdickungen außer unerwünschten Abdrücken auf dem Transportgut auch noch zur Folge, daß sich an den Verbindungsstellen Staub und Schmutz ansammelt, was zu unangenehmen Verschmutzungen des Textilgutes führt. Junction of adjoining tape sections Die Connection points of tape sections are often designed or overlapping have an underlaid, butted seam. This has thickenings at the junction as a result, which marks on the conveyor belts in many areas of application the transported goods. This disadvantage arises especially with conveyor belts Made of polytetrafluoroethylene (so-called "PTFE") glass fabrics. When using such conveyor belts for example in the textile industry for the automatic production of shirt collars In addition to unwanted marks on the transported goods, the thickenings also have them the result that dust and dirt collects at the joints, which leads to leads to unpleasant soiling of the textile material.

Der Erfindung liegt die Aufgabe zugrunde, ein Band, insbesondere ein Transportband aus PTFE-Glasgewebe zu schaffen, bei dem die Verbindungsstellen wesentlich geringere bzw. überhaupt keine Verdikkungen aufweisen. The invention is based on the object of a tape, in particular To create a conveyor belt made of PTFE glass fabric, in which the connection points have significantly less thickening or no thickening at all.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die einander zugewandten Stirnseiten der Bandabschnitte gegenläufige Abschrägungen mit einander zugewandten Schrägflächen aufweisen, und die Schrägflächen miteinander verbunden sind. Dadurch erreicht man, daß die Verbindungsstelle allenfalls eine minimale Verdickung mit kaum merklichen Ubergängen von einem Transportbandabschnitt zum nachfolgenden Transportbandabschnitt aufweist. This object is achieved according to the invention in that the one another facing end faces of the band sections opposite bevels with each other Have facing inclined surfaces, and the inclined surfaces connected to one another are. As a result, the connection point is at most minimally thickened with barely noticeable transitions from one conveyor belt section to the next Has conveyor belt section.

Dadurch werden störende Abdrücke der Verbindungsstelle bzw.This causes annoying impressions of the connection point or

Nahtstelle auf dem Transportgut verhindert. Weiterhin werden Ansammlungen von Schmutz und Staub vermieden. Bei einer Reinigung der Transportbänder über Abschaber wird ein vorzeitiger Verschleiß durch ständiges Anstoßen des Schabers an der Ubergangsstelle vermieden.Prevents seams on the transported goods. There will continue to be accumulations Avoided of dirt and dust. When cleaning the conveyor belts with scrapers premature wear is caused by the scraper constantly hitting the transition point avoided.

Die Verbindung der Abschrägungen kann beispielsweise durch Verschweißen der Bandabschnitte miteinander erfolgen.The bevels can be connected, for example, by welding of the tape sections are carried out with one another.

In weiterer Ausbildung der Erfindung kann vorgesehen sein, daß zwischen den Schrägflächen eine Zwischenlage angeordnet ist.In a further embodiment of the invention it can be provided that between an intermediate layer is arranged on the inclined surfaces.

Diese Zwischenlage besteht vorzugsweise aus einem anderen Werkstoff als das Transportband. Ein PTFE-Glasgewebe ist nämlich ein thermoplastischer Werkstoff, der jedoch nicht - wie andere Thermoplaste -auf herkömmliche Weise schweißbar ist, da PTFE bei der erforderlichen Schweißtemperatur von 327"C in einen Gelzustand übergeht und hierbei zerstört wird. Dies kann dadurch vermieden werden, daß die Zwischenlage zwischen die Schrägflächen eingebracht wird, wodurch ein Schweißvorgang unter Einwirkung von Druck und Temperatur jeweils zwischen den Schrägflächen und der Zwischenlage erfolgen kann.This intermediate layer is preferably made of a different material than the conveyor belt. A PTFE glass fabric is a thermoplastic material, which, however - like other thermoplastics - cannot be welded in the conventional way, because PTFE turns into a gel state at the required welding temperature of 327 "C and is destroyed in the process. This can be avoided in that the intermediate layer is introduced between the inclined surfaces, creating a welding process under action of pressure and temperature between the inclined surfaces and the intermediate layer can be done.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen: Fig. 1 eine Draufsicht auf einen Transportbandabschnitt; Fig. 2 eine Seitenansicht des Transportbandabschnittes gemäß Fig. 1; Fig. 3 eine Schnittdarstellung des Verbindungsbereiches in vergrößertem Maßstab.An exemplary embodiment of the invention is shown in the drawing. 1 shows a plan view of a conveyor belt section; Fig. 2 a Side view of the conveyor belt section according to FIG. 1; Fig. 3 is a sectional view of the connection area on an enlarged scale.

Ein Transportabschnitt 1 aus PTFE-Glasgewebe weist eine Verbindungsstelle 2 auf, an der sich jeweils gleich ausgebildete Transportbandabschnitte la und lb aneinander anschließen. Die sich überlappenden Bereiche weisen gegenläufige Abschrägungen mit einander zugewandten Schrägflächen 3 und 4 auf und sind an diesen unter Einschaltung einer Zwischenlage 5 miteinander verbunden. Wie ohne weiteres feststellbar, ist durch die erfindungsgemäße Maßnahme die Verdickung im Bereich der Verbindungsstelle 2 kaum noch merkbar.A transport section 1 made of PTFE glass fabric has a connection point 2, on which each identically designed conveyor belt sections la and lb connect to each other. The overlapping areas have opposite bevels with facing inclined surfaces 3 and 4 and are switched on at these an intermediate layer 5 connected to one another. As can be seen without further ado by the measure according to the invention, the thickening in the area of the connection point 2 barely noticeable.
