Abstract: A method and a device for separating the sheets of a stack are described. At least one flexing device engages at the top sheet of the stack, tensioning or arching the edges of the top sheet. This creates a clearance between the top sheet and a second, lower sheet. A separating edge is inserted into said clearance so that the top sheet can be removed by a transport arrangement.

Abstract: A transport device for paper sheets incorporates driven rollers which frictionally engage the paper sheets and are mounted on shafts arranged parallel with one another in the transport direction. Filaments extending in the transport direction are utilized to bias the paper sheets from below against the rollers. The filaments permit the paper sheets to glide or slide thereover and extend between the rollers in a lower tangential plane, said filaments being mounted elastically at one extremity thereof. A slight inclination of the shafts of the rollers causes the paper sheets to be transported while engaging a lateral guiding edge to accomplish transportation of said sheet in an accurately aligned manner.

Abstract: A soil cultivation implement comprising a frame adapted to be coupled to a drive means, and said frame supporting, one behind the other in the direction of travel, first cutting means for cutting the ground substantially vertically, second cutting means for dividing the ground substantially horizontally and lifting it in a rearward direction, and a substantially horizontal rotor. The rotor is provided with power means from said drive means and is adapted to be driven rotationally and provided with prongs for penetrating the surface of the ground. The prongs are disposed helically on a rotor shaft in a least three rows staggered uniformly in relation to one another in the peripheral direction. The prongs are further substantially rectilinear and rigidly fastened substantially tangentially on the rotor shaft. Furthermore the prongs enclose in relation to the radii associated with their fastening points an angle of less than 90.degree.
