Definitions
- the most widely utilized method at present is so-called free winding between three cylinders.
- the core is inserted, by means of inserting arms, in the cradle formed between three cylinders with parallel axes, which set it in rotational motion, causing winding thereon of the web material.
- the log Once the log has been formed it is ejected and a new core is then inserted.
- the diameters of the commercial cores normally used are variable in size.
- the range of variation of the core diameters normally goes from 30 mm to 100 mm. Cores of small diameter are used for rolls of web material intended for domestic use, while cores of larger sizes are reserved for industrial use.
- EP-0853 060A, EP-0387 214A EP-0524 158A and Patent abstract of Japan, vol 17, no. 144 (M-1386), 23rd March 1993 (1993-01-20) disclose rewinding machines wherein the core inserting arm is pivoted on a fixed axis, thus showing the drawbacks mentioned above.
- the cores 1 are made to slide on a conveyor belt or a loading channel having guides 2 in the form of an inclined surface.
- An inserting arm 3 is curved in shape and has at its free end a plurality of rollers 4 (only one of which can be seen in the figure) consisting of idle mounted cylindrical rollers. The rollers 4 push the cores 1 into a winding cradle formed between three cylinders 6, 7, 8, where the web material is wound.
- the cylinder 6 is fixedly mounted.
- the cylinder 7 can be fixed or guided by rocker arms to adjust the distance between the skirts of cylinders 6 and 7.
- the cylinder 8, commonly known as the pressure cylinder, exerts pressure on the log being formed and is supported by a pair of rocker arms 20, so as to be able to follow the increase in diameter of the log.
- the inserting arm 3 is pivoted at the centre of an eccentric body 9, on an axis identified by letter A in the figures.
- the eccentric body 9 is in turn pivoted on an axis B at a distance ⁇ from the axis A.
- the distance ⁇ between the fulcrum A of the inserting arm 3 and the fulcrum B of the eccentric body 9 gives the eccentricity of the system.
- the eccentricity ⁇ can be selected as about 30 mm.
- a second arm 10 is pivoted integrally to the inserting arm 3 at A.
- a follower 11 is provided that follows the profile of a cam 12, rotation of which prevents a rocking movement of the inserting arm 3, so that the end rollers 4 follow such a path as to push the core 1 at its midline.

- Système selon la revendication 2, caractérisé en ce que ladite excentricité (ε) varie entre 5 mm et 100 mm.
- Système selon la revendication 1, caractérisé en ce que ledit corps excentrique (9) est réalisé pour pivoter autour de son propre appui (B) au moyen d'un système de bielle (14) et de manivelle (13).
- Système selon l'une quelconque des revendications précédentes, caractérisé en ce que le corps excentrique (9) peut être actionné manuellement.
- Système selon l'une quelconque des revendications 1 à 4, caractérisé en ce que ledit corps excentrique (9) peut être actionné de manière semi-automatique, à l'aide d'un moto-réducteur.
- Système selon l'une quelconque des revendications 1 à 4, caractérisé en ce que ledit corps excentrique (9) est actionné au moyen d'un encodeur automatique ayant une interface avec un ordinateur où les diamètres des noyaux (1, 1') sont préétablis.
- Système selon la revendication 1, caractérisé en ce qu'une échelle graduée (16) où sont indiquées les différentes valeurs possibles du diamètre des noyaux (1, 1') est associée audit corps excentrique (9), de façon à faciliter le réglage de la rotation du corps excentrique (9).
- Machine à rebobiner du matériau en feuille, caractérisée en ce qu'elle comprend un système d'introduction des noyaux dans le berceau d'enroulement selon l'une quelconque des revendications précédentes.
