Abstract: A backpack blower has a backpack with a load-bearing frame, a blower tube with a backpack-side tube section which is held on a rear side of the load-bearing frame, and a hand-side tube section which extends past a first side region of the load-bearing frame, a drive motor, an energy source for the drive motor, and an axial fan which is driven by the drive motor, has an axial fan axis, and is arranged in the backpack-side tube section of the blower tube. The backpack-side tube section of the blower tube runs with a main direction component in a backpack transverse direction of the load-bearing frame and has an axial blower tube end termination which projects laterally beyond a second side region of the load-bearing frame, which second side region faces away from the first side region, and/or is surrounded at least on a part of its circumference by a protective ring element which is connected to the load-bearing frame. The blower may be an electric leaf blower.

Abstract: A blower unit for a portable handheld blower apparatus has a housing section and a tubular receiving space, formed in the housing section, with a first axial end and a second axial end and with a longitudinal center axis. Arranged in the receiving space of the housing section is an axial blower for generating a blower air flow, the axial blower being driven by a drive motor. The receiving space has an intake opening at its first axial end and a discharge opening at its second axial end. In order to reduce operating noise, an air guide plate is arranged at an axial distance in front of the intake opening, the air guide plate having external dimensions that are greater than the external dimensions of the intake opening. An annular gap that supplies intake air is formed between the air guide plate and an outer periphery of the housing section.

Abstract: A device for guiding sheets in a sheet-fed rotary printing press or diecutter includes a sheet-guiding plate with openings and a cover plate disposed parallel thereto and being displaceable by an applied operating pressure. A flexible intermediate layer disposed between the sheet-guiding plate and the cover plate has passages with a cross section which is variable by the operating pressure. A sheet brake, a diecutter and a printing press having the sheet guiding device are also provided.
