Abstract (en)

[origin: CN108928661A] A device is connected with a nonwoven fabric winder (10) so that the nonwoven fabric is separated at a preset position in a period of winding to a winding shaft and partial nonwoven fabric which is generated by separation and has a free end aligned to the conveying direction of the nonwoven fabric is conveyed to the winding shaft that is configured in a manner of being opposite to the conveying direction. The invention further discloses a nonwoven fabric winder with the device and a driving device. The driving device drives the device from a waiting position to an operation position. Then thenonwoven fabric is wound on a first winding shaft by means of a contact roller (8). The device is also provided with a pressure element so that the first winding shaft is pressed to the contact rollerand the to-be-wound nonwoven fabric is wound on the first winding shaft because of friction. The device is used for separating the nonwoven fabric and partial nonwoven fabric is conveyed to a secondwinding shaft. The invention further relates to a method for operating the nonwoven fabric winder, wherein the method comprises the steps of winding the entered nonwoven fabric around the first winding shaft; if a separation state (S2) is detected, separating the nonwoven fabric, and furthermore after separation of the nonwoven fabric is finished, conveying the partial nonwoven fabric in the direction of the second winding shaft.
