摘要： The invention relates to an arrangement in a hot air aggregate comprising a cover (2) having a built-in fan (3), an enclosed chamber (4) after said fan (3) which extends into a conically formed, front portion (5), to which a burner unit (7) having an enclosed burner (9) supplied witha gas flow and a nozzle (10) are provided via a connecting coupling sleeve (6). Said fan (3) is fixed via a sealing means (11) against an inner tube (12) insulated from said cover (2) and delimits the back portion (13) of the enclosed chamber (4) and its opposite front portion (14) extends into the conical portion (5), which comprises on its inner mantle surface (15) inclined wings to give the streaming air through the same an extra rotation before its passage into the burner (9), said chamber (4) comprises an air guard (16) for sensing the right air flow into the burner (9) at the same time as in front of or after said fan (3) there are within said cover (2) integrated an electronic controlling unit (17) and a magnetic valve (18) for adjusting of air- and gas flows, said burner unit (7) comprises an adjusting means (19) for ignition and starting of the fan (3) when the pressure has been increased sufficiently in the chamber (4) at the same time as a sensor gives a signal to said magnet valve (18) to open said gas supply for ignition of a gas flame enclosed in the burner, and said nozzle (10) is double mantled having the possibility of cooling by aid of cooling air in the gap space (20) of the double mantle (21).

摘要： An arrangement for an apparatus (1) for application of roof covering (2) and comprising a wagon (4) moveable by aid of wheels (3) intended to join together two unrolled rolls of roof covering in connection to a joint (5) on top of each other lying covering layers (6, 7) by aid of a hot air aggregate (8) supported by said wagon (4), which via a nozzle (9) blows hot gas into said joint (5) at the same time as the wagon (4) is moved forwards and at least one operating pressure roller (10) included in said wagon (4), which is intended to press together the covering layers (6, 7) lying on top of each other. The hot air aggregate (8) is turnably supported onto the one front outer portion (12) of said wagon (4) by aid of a hinge (11) having its nozzle (9) turnable inwards between those covering layers (6, 7), which shall be welded together and said operating pressure roller (10) is provided in the front, central portion (13) of the wagon (4) immediately after the nozzle (9) on the same when it is in its turned in, active position and which comprises a middle portion (14) having a smaller diameter than adjacent outer portions (15, 16) for achieving two application surfaces (17, 18) against a joint surface (19) in the joint at the same time as an extra pressure roller (20) is provided after or behind the operating pressure roller (10) intended only to act against that surface of the joint (5), which the first, operating pressure roller (10) has not treated.
