摘要

A paperband tearing strip for severing a paper web that moves from a papermaking plant onto a winding drum. The tearing strip is composed of a paper strip which has two longitudinally running lateral folds along which the paper strip is folded on top of itself. The central strip part in relation to the lateral strip parts has a thickness which is at least 1.5 times greater, and the width of said central strip part is at least one fifth of the width of the paper strip. The widths of the lateral strip parts each are at least one tenth of the width of the central strip part. The central strip part is formed with at least one fold on account of which the central strip part is configured to be at least quadruple-layered.
