The rewinder comes with a coil upender of counter and blades-cutting blades or other longitudinal reducing tools. They are located transversely with respect to the course of supply in the website material, according to the dimensions of the pieces being obtained by reducing the net material in the reel. A variety of coil upenders have already been analyzed for intelligent location the cutting blades like a function of the material to be made. An illustration of system to carry out explained placement is explained in EP-A-1245354.

Winding mandrels, where tubular winding cores, corresponding in number, dimension and position towards the position, dimension and number of your pieces into in which the cutting resources separate the world wide web substance from the master reel getting unwound, happen to be fixed, are loaded time by amount of time in the rewinder. devices and Machines that get ready the mandrel using the tubular winding cores fixed thereon currently really exist. An illustration of a device on this kind is defined in WO-A-0061480 and in the related Western patent EP-B-1169250.

Downstream in the rewinders the winding mandrels are removed from the established rolls, that happen to be then sent to packaging.

Currently, integrated coil upenders for control over the many generation steps from the winder to packaging usually are not presented. Generally speaking, in currently used coil upenders there are actually three individual major procedures. These are typically:

winding of your nonwoven manufactured by the ongoing machine,
