The open fire has its exhaust gases conducted through ducts so that, irrespective of the duct damper (1) position, it provides access to the inner part of the fire insert. Using the damper, an exhaust gas duct is provided from the grate running backwards and upwards with at least two apertures. One aperture is closable by the damper and leads directly upwards to a chimney pipe (10), and the other ...

With the view to, before stapling sacks that have flat turned bottom parts (3, 5) in both ends of the flat sack, introduce a uniform stapling size and uniform stapling thickness to the sacks, one folds each sack so that each of the sack's both ends form an end piece (9, 11) with associated flat turned bottom part in toward the centre of the sack (7). The turning occurs toward the side that is oppo...
