Abstract (en)

The process for winding a paper or cardboard web (12) on to a drum (14, 14') comprises feeding it over a carrier roller (20). A nip (22) is formed between the carrier roller and drum and the web is separated from a full drum (14) and moved to a new drum (14'). The traction of the web during the transfer process between the full and new drums is controlled to keep it below the value at which uncontrolled tearing of the web could occur. An Independent claim is included for a machine for carrying out the process.

Abstract (de)

Bei einer Wickelmaschine 10 zum Aufwickeln einer Materialbahn 12 wie insbesondere einer Papier- oder Kartonbahn auf einen Tambour 14, 14' wird die Materialbahn 12 über eine Tragtrommel 20 geführt und zwischen der Tragtrommel 20 und dem Tambour 14, 14' ein Wickelspalt 22 gebildet und die Materialbahn 12 für einen jeweiligen Tambourwechsel bei von der Tragtrommel 20 abgesetztem vollem Tambour 14 und der Tragtrommel 20 zugeordnetem neuem, leerem Tambour 14' durchtrennt. Die Wickelmaschine 10 ist mit einer Steuer- und/oder Regeleinrichtung 26 versehen, durch die der Bahnzug im Bereich zwischen dem vollen und dem neuen Tambour 14 bzw. 14' in Abhängigkeit von dem Trennvorgang so steuerbar und/oder regelbar ist, daß dieser während des Trennvorgangs unterhalb eines kritischen Wertes gehalten wird, ab dem es im Bereich zwischen dem vollen und dem neuen Tambour 14 bzw. 14' zu einem unkontrollierten Reißen der Materialbahn 12 kommen kann. <IMAGE>
