Abstract (en)

[origin: CN108928660A] The invention discloses a device that can be combined into a web winder (1) to separate a web. A cutting section (106) of a separating section (100) extends over the width of the web and is fixedly orvibratingly driven relative to the axis of rotation of a contact roller (8), and a holding section (130, 140) is rotatably arranged about the axis of rotation. An operating section (102, 104, 105) places the cutting section in the retaining section, whereby the cutting section is not in contact with the web. The cutting section is moved across the axis of rotation of the device such that the cutting segment squeezes the web for separation. A sensor system (160) is used to detect at least one state of the separation section. The web winder winds the web onto the winding shaft by means of a contact roll and a pressing element. The pressing element presses the winding shaft against the contact roller so that the web is wound on the winding shaft around the circumference of the contact roller. The winder uses the device to separate the web and monitor the position of the cutting section. The invention also relates to a method for operating a winder.
