  • a rope end 2 can first be pushed into this sleeve approximately up to the middle of the hose 8 located on the sleeve 32, and the hose 8 pushed a short distance further on the sleeve until the hose end located above the rope end 2 has left the sleeve and rests on the rope, and fix this hose end to the rope. Then you can push the second rope end 3, which is to be connected to the rope end 2, into the sleeve 32 until it rests against the rope end 2, hold both rope ends axially against one another and pull off the sleeve 32, as shown in FIG. 25 and then fix the second hose end, thus forming a connection point of a rope loop according to the invention that is designed without a central connection.

Abstract

Une boucle de câble en fibres, notamment un câble d'entraînement du papier dans une machine à papier, est fermé par au moins un point de raccordement des deux extrémités (2, 3) du câble et est destiné à circuler en continu sur des rouleaux dans une machine ou une installation industrielle. Un tuyau flexible souple (8) est tiré sur les deux extrémités (2, 3) du câble qui se font face au point de liaison, de manière à les relier en faisant un pont par-dessus ledit point de liaison. Au moins lorsque le raccordement du câble est soumis à une traction, le tuyau flexible épouse étroitement la surface des sections (24, 25) du câble, et au moins ses extrémités sont reliées au câble (4, 5). De préférence, les deux extrémités (2, 3) du câble sont au moins provisoirement réunies par un raccordement central (6) et le tuyau (8) est tiré sur ce raccordement central (6).
