Abstract
A method and apparatus for wrapping paper and board rolls in a wrapper, in which method the roll (10) to be wrapped is conveyed to a wrapping station, is placed on support means and is rotated resting on said support means. The wrapper (24, 27) is threaded about the roll (10) to be wrapped so as to form at least two wrapper plies and the wrapper plies are bonded to each other at least partially with the help of a binder. The rolls to be wrapped are wrapped into at least two parallel and overlapped courses of wrapper using a wrapper web material whose surface is coated with a hot-melting and heat-sealable material that is melted prior to the wrapping of the wrapper about the roll in order to bind the superimposed plies of the wrapper to each other and to seal the joints of said overlapped courses of wrapper.
