Abstract: A method and an assembly is disclosed for sorting rolls of paper and paperboard web for shipment into a desired sequence based on customer orders, in which method and assembly a roll to be sortedis imported to an infeed conveyor (2), and from at least two first conveyors (3, 4, 5) is selected a suitable conveyor onto which the roll is transferred. Subsequently, the roll is transferred onto the selected conveyor so that its leading end remains at the receiving end of said selected conveyor, and the rolls are transferred onto the first conveyors (3, 4, 5) in a similar fashion so that the rolls thus placed onto the conveyors remain in a close disposition to each other so as to form a group of end-to-end abutting rolls until at least one of the first conveyors contains a roll group forming a unit load for an upender lift.

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.

Abstract: A method of recovering the thermal energy contained in the pressurized steam utilized during the production of thermomechanical pulp. The steam is applied to the primary side of a heat exchanger with water supplied to the secondary side in order to produce hot water. The water is vaporized to produce clean steam. The clean steam is then utilized to at least a first steam group of the drying sections of a paper manufacturing machine without increasing the pressure of the clean steam.
