4. Aufgabe4. Task

Die dieser Anmeldung zugrundeliegende Aufgabe ist dieThe task underlying this application is the

4.1 Beidseitige Verdrängung der Flüssigkeit oder des Gases aus dem Schlauch-Bereich der Schweißzone vor der Schweißung und Abtrennung. Dies erfolgt im kalten Zustand des elastischen Schlauchmaterials beim Zusammenpressen des Schlauches vor dem Schweißprozeß4.1 Displacement of the liquid or gas from both sides of the hose area of the welding zone before welding and separation. This takes place when the elastic hose material is cold when the hose is compressed before the welding process

einerseits durch die Vorwölbung des Widerstandsbandes an der späteren Trennstelleon the one hand by the bulging of the resistance band at the later separation point

- andererseits durch eine keilförmige, von der Trennstelle aas «aeh beiden Seite« vergrößernde Abweichung von der Planparallelität der Kontur im eigentlichen Schweißbereich (Schweißzone'x1 in Fig. 4), die sich noch weiter außen (Öbergangszone'y1) stark bis auf den Schlauchdurchmesser erweitert.- on the other hand, by a wedge-shaped deviation from the plane parallelism of the contour in the actual welding area (welding zone x 1 in Fig. 4), which increases from the separation point to "both sides", and which widens even further out (transition zone y 1 ) to the hose diameter.

4.2 Durchführung der angenähert planparallelen Verschweißung der Innenwände über ein beliebig langes Teilstück des Schlauches.4.2 Carrying out the approximately plane-parallel welding of the inner walls over a section of the hose of any length.

4.3 Einprägung einer quer zur Schlauchachse verlaufenden Furche in der räumlichen Mitte der Schweißzone als Sollbruchstelle bzw. für das Abschmelzen oder Abreißen oder Abschneiden.4.3 Embossing a groove running transversely to the hose axis in the spatial center of the welding zone as a predetermined breaking point or for melting, tearing or cutting.

5.2 Gleichgeformte, gewebeuahullte Widerstandsbänder (# 2), die auf den geformten Druckstücken (# 1) befestigt sind.5.2 Uniformly shaped fabric covered resistance bands (#2) attached to the shaped pressure pieces (#1).

5.3 Mechanische Halterungsstücke (Griffstuck ff 3) zur Aufnahme und Fixierung der Lage des Schlauches (ff 4) im Bereich der Schweißstelle.5.3 Mechanical holding pieces (handle piece ff 3) for holding and fixing the position of the hose (ff 4) in the area of the welding point.

5.4 Arbeitszyklen:5.4 Working cycles:

5.41 Geformte Druckstücke (ff 1) mit dem Widerstandsband (ff 2) geöffnet.5.41 Shaped pressure pieces (ff 1) with the resistance band (ff 2) opened.

5.43 Schwaißvorgang auslösen:5.43 Initiate welding process:

5.431Geformte Druckstücke (Df 1) mit den Widerstandsbändern (ff 2) schließen eich. Dadurch wird das im Schlauch befindliche Medium aus dem Schweißbereich V(FIg. 1) verdrängt. Der Vorschub bzw* der Weg der Drucketücke ist einstellbar und in der unteren stellung begrenzt um eine definierte Höhe der Schweißstelle definieren zu können.5.431Formed pressure pieces (Df 1) with the resistance bands (ff 2) close. This forces the medium in the hose out of the welding area V (Fig. 1). The feed or the path of the pressure pieces is adjustable and limited in the lower position in order to be able to define a defined height of the welding point.

5.432 Nach oder während der Drucksfückbewegung schaltet sich der die Widerstandsbänder durchfließende strom ein und erwärmt die Widerstandebänder.5.432 After or during the pressure-feeding movement, the current flowing through the resistance bands is switched on and heats up the resistance bands.

Die Heizleistung und damit die Stromflußdauer sowie die Temperatur wird durch einen Zeitschalter bestimmt (einstell- und fixierba?).The heating power and thus the duration of the current flow as well as the temperature are determined by a timer (adjustable and fixable).
