An arrangement for wrapping big web rolls. The arrangement comprises a support system for supporting and rotating a web roll and a frame surrounding the web roll and having means for leading a wrapper around the roll. The frame includes a guide strap and operating means for applying the strap on the mantle surface of the roll and for keeping the wrapper between the strap and the roll. The operating means has a support position, in which it supports a portion of the guide strap at a distance from the roll, thereby causing the guide strap to bend off at a certain point from the surface of the roll. For bringing the front end of the wrapper to follow the roll, the operating means can be moved around said roll. Whereby the bending-off point of the guide strap also moves around the roll and an increasing portion of the guide strap settles on the mantle surface of the roll to keep the wrapper closely thereon when rotating the roll during simultaneous feeding of wrapper thereto. |
