In addition, the present invention provides a roll manufacturing device characterized by comprising: a shaping unit for shaping a base material into a web; a transferring unit for transferring the shaped web; and a winding unit for winding the transferred web into a roll.
Claims17
A method of manufacturing a roll comprising:
- shaping a raw material into a web;
- transporting the shaped web;
- suppressing vibrations of the web using a first vibration suppressing unit disposed on at least a first point of a path along which the web is transported;
- winding the transported web into a roll,
- wherein the first vibration suppressing unit comprises a first ultrasonic vibrator and a second ultrasonic vibrator spaced apart from and facing each other such that the web is disposed therebetween, wherein the first ultrasonic vibrator and the second ultrasonic vibrator hold the web therebetween in a non-contact manner by generating ultrasonic vibrations and applying repelling force induced from the ultrasonic vibrations onto the web such that uniform pressure is applied onto the web, thereby suppressing vibrations of the web.
