The invention provides spirally wound paperboard cores for winding of textiles and other materials and which have enhanced high speed winding capability. The spirally wound paperboard plies forming the body wall of the paperboard core have a predetermined spiral winding angle with respect to the axis of the cylindrical body wall of greater than 71 degrees. In winding cores having a relatively large ID of between about 4.8 in. (120 mm) and 6 in. (150 mm), the paperboard plies forming the spirally wound cores have a winding angle of greater than 74 degrees. In winding cores having a lower ID of less than 4.8 inches (120 mm), all of the paperboard plies have a width of 3.5 in. (89 mm) or less and a spiral winding angle of greater than 71 degrees.
Cette invention concerne des mandrins en carton spiralé pour le bobinage de rouleaux de tissu et autres matériaux, conçus pour une meilleure tenue aux grandes vitesses de bobinage. Les bandes de carton formant la paroi du mandrin sont enroulées en spirale selon un angle prédéterminé de plus de 71 degrés par rapport à l'axe du mandrin. Les mandrins de diamètre intérieur relativement élevé - entre 4.8 po (120 mm) et 6 po (150 mm) - sont spiralés selon un angle supérieur à 74 degrés. Ceux de plus petit diamètre intérieur, c'est-à-dire moins de 4.8 po (120 mm), sont formés de bandes d'au plus 3.5 po (89 mm) de largeur spiralées selon un angle de plus de 71 degrés.
