Description

Bei Grundrollen für Schleppnetze ist es bereits bekannt geworden, auf die Achsen der Grundrollen Auglappen verschiedener Länge zu setzen, in welche die Verbindungsketten oder Seile eingeschäkelt werden, um die Rollen parallel zur Fahrtrichtung zu halten. Derartige Einrichtungen sind aber teuer und auch beim Zusammenstellen der Netze schwierig zu handhaben. Diese Mangel ίο sind durch den Erfindungsgegenstand, der sich durch Einfachheit, Billigkeit und leichte Handhabung auszeichnet, behoben. Er besteht in einer Grundrolle mit drehbar in ihr gelagerter Buchse, die mit einer derart schräg zur Achse der Buchse verlaufenden Durchbohrung versehen ist und mit dieser derart das Grundtau festsitzend umgreift, daß ihre Achse beim Schleppen des Netzes etwa senkrecht zur Zugrichtung liegt.
Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt. Es zeigen:In the case of basic rollers for trawls, it is already known to put eyelids of different lengths on the axes of the basic rollers, into which the connecting chains or ropes are shackled in order to keep the rollers parallel to the direction of travel. Such devices are expensive and difficult to handle when assembling the networks. These deficiencies ίο are remedied by the subject matter of the invention, which is characterized by simplicity, cheapness and ease of use. It consists of a base roller with a bushing rotatably mounted in it, which is provided with a through-hole which runs obliquely to the axis of the bushing and which tightly engages around the base rope in such a way that its axis is approximately perpendicular to the pulling direction when the net is towed.
The invention is shown in an exemplary embodiment in the drawing. Show it:

o. dgl. zusammengehalten und in die Lagerbüchsen m eingesetzt sind. In diesen Buchsen ist eine Pockholzbuchse e drehbar gelagert, die eine schräg zu ihrer Achsenrichtung verlaufende Durchbohrung/ hat. Die Schräge dieser Durchbohrung ist je nach der beabsichtigten Lage der Rolle auf dem Grundtau in Anpassung an die dort beim Schleppen zu erwartende Schrägstellung des Grundtaues zu der quer zur Zugrichtung liegenden Geraden gehalten. Die Buchse wird auf dem Grundtau derart festgelegt, daß beim Schleppen ihre Achse quer zur Zugrichtung liegt, so daß die auf sie aufgesetzte Rolle sich in der Zugrichtung dreht. Zwischen den einzelnen Rollen sind Abstandsmittel i auf dem Grundtau aufgesetzt.o. The like. Are held together and inserted into the bearing bushes m. A Pockholzbuchse e is rotatably mounted in these sockets and has a through-hole / which runs obliquely to its axial direction. Depending on the intended position of the roller on the base rope, the incline of this through-hole is kept in adaptation to the inclination of the base rope to the straight line lying transversely to the direction of pull, which is to be expected there during towing. The bushing is fixed on the base rope in such a way that when towing its axis is transverse to the direction of pull, so that the roller placed on it rotates in the direction of pull. Spacer means i are placed on the base rope between the individual rollers.
