    • The present invention concerns a winding section (1) for winding a continuous band (200) of bags around one or more cores (4). The section includes a feed path (200) of the band, a winding device (10) for winding the band around the core (4) and appropriate tear means (60, 60', 61, 61', 150) to cause the tear of the band (100) in correspondence of the completion of a winding and to facilitate the beginning of a subsequent winding. In accordance with the invention, the winding device (10) includes a shaft (12) to which two rotatable discs (11) are connected rigidly provided each one of them with a first (16) and a second spindle (17). The spindles are both sliding axially with respect to the disc and also rotatable axially to realize the winding of a roll in formation. A mobile core loader (3) and a movement system (50, 51, 55, 100) are also included, the last one synchronized in such a way that when a spindle (16, 17) is in rotation to complete a first winding the second spindle is retracted in such a way that the loader is set in axis with it to spear the cores after its extraction. Subsequently, the moving apart of the loader (3) is controlled and, in proximity of the completion of the first winding, the whole device (10) is made to rotate around its axis (12) that causes an inversion of position between the two spindles (16, 17). The second spindle extracted is now set in rotation in such a way that, after the tear, it initiates a new winding while the first one is retracted so as to make the roll formed fall.
    • 本发明涉及一种用于将一个连续带(200)的卷绕在一个或多个芯(4)周围的卷绕部分(1)。 所述部分包括所述带的进给路径(200),用于将所述带缠绕在所述芯(4)周围的缠绕装置(10)和适当的撕裂装置(60,60',61,61',150)以引起所述撕裂 (100)对应于绕组的完成并且便于随后的卷绕开始。 根据本发明,卷绕装置(10)包括轴(12),两个可旋转盘(11)刚性地连接到所述轴(12)上,每个旋转盘每个都具有第一主轴(16)和第二主轴(17)。 主轴相对于盘轴向滑动并且也可以轴向旋转以实现卷的卷绕。 还包括移动式装载机(3)和移动系统(50,51,55,100),最后一个以这样一种方式同步,即当主轴(16,17)旋转以完成第一绕组时, 第二主轴以这样的方式缩回,使得装载机在其提取之后将其设置成轴线以刺穿芯。 随后,装载机(3)的移动分开被控制,并且在第一绕组完成附近,使整个装置(10)围绕其轴线(12)旋转,导致两者之间的位置反转 心轴(16,17)。 所提取的第二主轴现在被设置成旋转,使得在撕裂之后,它启动一个新的卷绕,而第一个被拉回以使辊形成下落。

    • A winding apparatus (10) has a rotary element (20) that is rotatable about a winding axis. A roller (50) is disposed adjoining the rotary element. The roller and rotary element together define a nip (48). A guide shoe (52) has a chute wall (70) and a plenum (68). The chute wall is aligned with the nip. The chute wall has an inner end disposed between the roller and rotary element and an outer end spaced from the roller. The chute wall has a plurality of bores (72) communicating with the plenum. In use, gas blown through the bores propels a web to the nip in a fluid film. The free end of the web is guided from an outfeed end of the nip in a loop to a second position adjoining the inner end of the guide shoe. During the guiding, the rotary element is rotated against the loop. This continues until the web overlaps and is cinched.
    • 卷绕装置(10)具有围绕卷绕轴线旋转的旋转元件(20)。 辊(50)设置成邻接旋转元件。 辊和旋转元件一起限定了辊隙(48)。 导靴(52)具有滑槽壁(70)和增压室(68)。 斜槽壁与辊隙对齐。 斜槽壁具有设置在辊和旋转元件之间的内端和与辊间隔开的外端。 斜槽壁具有与充气室连通的多个孔(72)。 在使用中,通过孔吹出的气体将纸幅推入流体膜中的辊隙。 腹板的自由端从辊隙的出料端引导到与导靴的内端相邻的第二位置。 在引导过程中,旋转元件相对于回路旋转。 这一直持续到网络重叠并被束缚。
