    Abstract: The rewinding machine includes a first winding cradle formed between a first winding roller, a second winding roller and a third winding roller. The first winding roller and the second winding roller define a nip through which there pass the winding cores with the web material being wound around them. The rewinding machine also includes a feed path of the winding cores that pass between the first winding roller and the third winding roller. A second winding cradle is formed between the first winding roller, the second winding roller and a fourth winding roller. The rewinding machine also includes a rolling surface extending around the first winding roller and defining a feed channel of the winding cores.

    Abstract: A reel unwinder including a first unwinding position, in which a first reel is positioned; a second unwinding position, to which the first reel is transferred when it is replaced with a second reel; a stand-by position, in which the second reel is kept in stand-by; a first unwinding member adapted to start rotation of the second reel when the first reel is replaced with the second reel. Moreover, the unwinder includes a second unwinding member, with at least one endless flexible element. The endless flexible element extends from the first unwinding position to the second unwinding position, and is adapted to maintain the first reel in contact with the second unwinding member and in rotation by the second unwinding member in the first unwinding position, in the second unwinding position and while it is being transferred from the first unwinding position to the second unwinding position.

    Abstract: The rewinding machine includes a first winding cradle, formed between a first winding roller, a second winding roller and a third winding roller and a second winding cradle formed between the first winding roller, the second winding roller and a fourth winding roller. The first winding roller and the second winding roller define a nip through which nip the winding cores, around which the web material is found, pass and the web material is fed towards a roll being formed in the second winding cradle. A severing member is furthermore provided, acting on the web material between a winding core and the nip, to sever the web material thus generating a tail edge of a completed roll and a leading edge of a new roll to be wound.

    Abstract translation: 复绕机包括形成在第一卷绕辊,第二卷绕辊和第三卷绕辊之间的第一卷绕托架和形成在第一卷绕辊,第二卷绕辊和第四卷绕辊之间的第二卷绕托架。 第一卷绕辊和第二卷绕辊限定了夹持部,通过该辊隙,卷材被卷绕在其上,卷材被卷绕在其周围,并且卷筒纸材料被输送到形成在第二卷绕托架中的卷筒。 此外,还提供了一个切割构件,其作用在卷材和辊隙之间的幅材材料上,从而切割幅材材料,从而产生完整辊的尾边和待卷绕的新辊的前缘。
