Abstract: The invention relates to a method for separating and categorizing at least one substrate (02; 03) that originates from a sheet source (47) or is transported in the form of a material web (02) to a cross-cutting apparatus and is separated into a multiplicity of sheets (03) there, wherein the respective sheets (03) are inspected in respective inspection operations with regard to at least one property that the substrate (02; 03) already had before the particular separating operation or severing operation, and wherein the sheets (03) are each assigned to one of at least three categories in an assigning operation on the basis of the result of the inspection carried out in the particular inspection operation, and wherein each of the sheets (03) is deposited on a delivery pile (06; 07; 08) corresponding to its category, and to a substrate categorizing machine (01), which has a sheet source (47) or a material-web source (09) and a cross-cutting device (11), wherein the substrate categorizing machine (01) has, downstr

Abstract: The invention relates to a sheet guide element for use in an apparatus for transporting sheets by means of a gripper system having at least two grippers spaced apart from each other and a sheet guide surface defined by the sheet guide element. Here, the sheet guide element is provided with depressions in the sheet guide surface, running parallel to the transport direction, at least in some sections, in order at least partially to accommodate the grippers, so that the sheet guide surface described by the sheet guide element in the transport direction runs, at least in some sections, at the same height as the movement path of the sheet leading edge fixed in the gripper system.

Abstract: A doctor blade device (01) for cleaning a surface has a doctor blade (03) and a tub (09) for receiving the material stripped from the surface by the doctor blade. The doctor blade is movable between a position in which it projects out of an opening (13) of the tub and a position in which it is submerged in the tub. A closure element (07) closes the opening in the submerged position of the doctor blade.

Abstract: A water jet cutting device is used to cut a paper web into a plurality of partial paper webs. The water jet cutting device is placed between the output of a web-fed rotary printing press and the input of a folder which folds the plurality of partial paper webs.

Abstract: The invention relates to a device for cutting paper webs (01) for forming several partial webs. The inventive device is arranged between an output of a printing machine and the input of a folder for folding the cut partial webs. Said device comprises a water jet cutting appliance (10).

Abstract: In the automatic transport of rectangular spinning cans between a can filling station and the work stations of textile machines which process sliver, it is known to arrange a can storage device in association with the can filling station, with a section of the can storage device for receiving empty cans from a traveling can transport vehicle and a section for storing and transferring full cans to the can transport vehicle, and with the can filling station between these two sections. The present invention contemplates the ordered and positionally exact transfer of the cans to and from the can transport vehicle by transferring of empty cans from the can transport vehicle to the empty can storage section such that the transferred empty cans immediately follow the empty cans already stored thereat. In the transfer of full cans to the can transport vehicle, a leading one of the full cans to be transferred is transferred into a corresponding leading one of the occupyable parking spaces on the can transport vehicle.
