Abstract: A method for monitoring breathing air of a person breathing via a face mask (8). In the method pressure of inhaled air and partial pressure of oxygen before oxygen enters in the face mask (8) are measured. A partial pressure of oxygen in lungs of the person is estimated on the basis of the measured pressure of inhaled air and the measured partial pressure of oxygen. Also at least one physical characteristics of lungs is taken into account. The estimated partial pressure of oxygen in lungs is compared with a threshold. An indication of impending hypoxia is provided to the person, if the comparison indicates that the estimated partial pressure of oxygen in lungs is at a level lower than the threshold. The present disclosure also relates to an apparatus (6) for implementing the method.

Abstract: A method for placing headers in connection with the packing of paper, cardboard, pulp or equivalent web material reels, in which method, one multiaxis industrial robot (1) or equivalent apparatus picks inner headers (2) and outer headers (9) to be placed in the paper reel from storage racks or places (3, 3?, 10, 10?). The invention is implemented such that the inner headers (2) and/or the outer headers (9) are transferred to placing manipulators (4) which move in the longitudinal axial direction of the paper reel and take the inner headers (2) at the heads of the paper reel (5) and/or equivalently the outer headers (9) onto head press planes (11) with a motion in the longitudinal axial direction of the paper reel (6) and in its cross direction (7) or a combination of these motions.

Abstract: The invention relates to a method for packaging rolls, particularly paper web rolls; the method includes the steps of taking a roll into a supported position on a roll rotation station and wrapping onto the roll a paper wrapper or the like material dispensed by means of at least one wrapper dispensing station and dispensing means, whereby the wrapper is wound so as to form either a centered wrapping or an overlapping wrapping. The invention is implemented by way of aligning the roll for the wrapping operation by means of transferring the roll rotation station laterally in the axial direction of the roll in regard to the wrapper dispensing system. The invention also relates to an apparatus and a novel roll package utilizing the method.

Abstract: A package of a roll, particularly a paper web roll comprising a wrapper, particularly a paper web wrapper wound stagewise into at least two wrappings about the roll in an overlap fashion. The paper web wrapper is wound about the roll in a slightly helical manner so that the edges of the wrapper layers overlap in a staggered fashion. The staggered edges of the overlap wrapping are formed so that each superposed wrapper layer conceals the underlying wrapper layer, whereby in a finished wrapping of a product only one wrapper edge remains visible.
