Abstract: A binary atomizing flat-jet nozzle with rectangle characteristic comprises a mixing head forming a mixing chamber with two mutually orthogonal connectors for a gaseous and a liquid medium, further a preferably tubular connector connecting to those connectors and a snout forming the slitted nozzle discharge. A metering inset with a cylindrical blind bore is mounted in the second connector supplying the liquid, the blind bore issuing inside the mixing chamber bilaterally into cross-bores. The snout comprises an offset bore with arched bottom. A baffle with a sharp-edged central transmission aperture rests on the bore offset and comprises an inside diameter less than the diameter of the offset snout bore. A nozzle with the above features is characterized by its simple design, easy manufacture and very uniform liquid distribution (so-called rectangle characteristic).

Abstract: Machine for producing pattern cardboard articles, in particular folding boxes, having a table board on which a scoring board and/or the workpiece comprising cardboard material are clamped firmly by providing that the table board and the scoring board comprise porous, i.e., air-permeable, but hard material, such as particle board material, and that to effect the firm clamping, a pneumatic negative pressure is generated beneath the table board, and that to produce scoring lines, a scoring tool disposed on a transporting device, so that each point on the workpiece is approachable by the tool. Further tools, specifically a face milling tool for producing the scoring grooves, a marking tool and/or a cutting tool for cutting out the pattern, may also be disposed on the transporting device.
