Abstract: The invention relates to a fairing assembly for a commercial vehicle, the fairing assembly comprising at least one deflector device configured to be mounted to a frame of the commercial vehicle, and to be arranged in front of at least one drive axle of the commercial vehicle, wherein the deflector device comprises at least two air guiding surface facing each other, the air guiding surfaces extending towards each other in the longitudinal direction of the vehicle towards the rear of the commercial vehicle thereby bounding at least one channel for air flowing under the commercial vehicle, the channel tapering in the longitudinal direction of the vehicle towards the rear.

Abstract: A heat-sealable foil is shaped around a shaping pipe to form a tube and during removal from the shaping pipe is provided with transverse seams by means of transverse heating jaws. The resulting bags are filled by means of a fill pipe and a dosaging worm or auger. A conduit leads from the lower end of the shaping pipe to a bellows and to a bottle of protective gas. The bellows forms a closed chamber whose volume is periodically increased and reduced in the operating rhythm of the bag forming apparatus by means of drive members. Thus the pressure conditions at the end of the shaping pipe can be influenced periodically, so as to avoid that the filled or sealed bags contain undesirable air inclusions or, when filling under protective gas, so as to avoid greater losses of protective gas from leaking into the open air.

Abstract: An apparatus for making, filling, closing and boxing bags includes a vertically oriented hollow mandrel about which a hose of sealable sheet is continuously formed, a device for cylindrically providing a transverse seam on the hose; a cutting device for cyclically severing the hose at the transverse seam for providing precedingly filled, sealed bags; a base plate situated underneath the mandrel for supporting thereon serially positioned and advanced, upright-oriented bag-receiving boxes open at their top and bottom; an opening provided in the base plate and aligned with the mandrel; and a vertically displaceably supported bag grasping device for penetrating through the opening into a box positioned underneath the mandrel and for downwardly pulling a filled and closed bag into the box.

Abstract: An apparatus for forming, filling and closing bags has a hollow mandrel on which a hose is continuously formed from a sheet; two vertically reciprocating and horizontally oppositely movable shoes underneath the mandrel for cyclically pressing together a first hose portion and providing a transverse seam thereacross as the hose and the shoes move downwardly in unison; a folding device cyclically forming bottom flaps from a second hose portion at opposite sides of the hose at the lower end of the mandrel above the first hose portion; a clamping device for firmly grasping the hose at the second hose portion and backing the bottom flaps along the entire hose cross section as it pulls the hose downwardly from the mandrel while moving simultaneously downwardly with the shoes and while the hose part that terminates at the bottom flaps is being filled with goods by gravity; and a cutting device for cutting through the transverse seam when the shoes and the clamping device have pulled the hose to a predetermined low p

Abstract: An elongate panel of a flexible sheet material which is not heat-sealable is formed into a succession of bags by advancing the panel in the direction of its length between a rectangular shaping tube and a folding box to form the panel into a tubular structure of rectangular cross section, applying a bead of adhesive material along one longitudinal edge of the panel and bringing the other longitudinal edge thereof against the adhesive to form a longitudinal seam, applying a bead of adhesive material to one narrow side and both wide sides of the tubular structure in the region defining the bottom of each bag to cause this bead to have the form of a U in a plane lying perpendicular to the length of the tubular structure, severing the tubular structure just downstream of each U-shaped bead, and forming the bottom of each bag by first folding in successive narrow sides of the tubular structure adjacent the associated line of severance, to give the wide sides the form of triangular ears each composed of two layers
