摘要： 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.
摘要翻译：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。
