Abstract: Described is a flat multifilament yarn with minimal opening tendency of the mutually bound-together filaments, expressed by the quantityVS(K.sub.F)>42%and with good compaction, expressed by the quantity(VG.sub.mean /VG.sub.max) * 100%>45%the VG quantities being degrees of intermingling determined using the Rothschild needle tester model 2040, VG.sub.mean being the arithmetic mean of 20 needle test measurements, and VG.sub.max being the maximum value of 20 needle test measurements. VS(K.sub.F) is the intermingling stability at a given total yarn tension K.sub.F determined by measuring the opening tendency of the flat multifilament yarn under dynamic-mechanical stress by a specific method.

Abstract: An air-displacement roller bears against a film roll and extends to the ends of the film roll. A film web is fed to a winding core via a contact cylinder and is wound to form the film roll. The air layers carried along by the roll and the film web are included between the particular uppermost roll plies and for the most part are pressed out of the film roll via the end faces of the latter by the air-displacement roller. Each of the two roller ends is movable via a pressure mechanism articulated on a roller holder, the air-displacement roller being pressed against the film roll with a linear force lower than 10 N/cm to higher than 0.2 N/cm.
