20110099782 | METHOD FOR CONVERTING A LETTER ENVELOPE PRODUCTION MACHINE FROM SET-UP MODE INTO A NORMAL PRODUCTION MODE - A method for converting a letter envelope production machine from a set-up mode to a normal production mode includes extracting letter envelope test samples via an extraction point of the letter envelope production machine, and moving a work station in the area of the extraction point between the extraction point at which letter envelope test samples are extracted and a production position in which letter wraps are produced. The work station is in the extraction position during the set-up mode and the letter envelope test samples are extracted at the extraction point. The letter envelope production machine continues running at a base speed during the conversion so that the movement of the work station to the production position during the operation of the letter envelope production machine will occur at base speed and set-up results obtained during the prior set-up mode will be maintained. | 05-05-2011 |
20110074146 | STATIONARY RADIAL COMPRESSED AIR SUPPLY - A roller air supply structure has a stationary compressed air supply having a stationary pressure chamber that can be loaded with pressure, and a rotatable roller that has at least one opening in a surface thereof operable to be loaded with compressed air from the stationary compressed air supply. The roller is surrounded in the axial area of the opening to be loaded with compressed air in the circumferential direction at least in sections by the stationary pressure chamber. The compressed air supply has a sealing element that can be moved by loading the pressure chamber with compressed air from a position of rest into a sealing position and by relieving the pressure of the pressure chamber to ambient pressure from the sealing position into the position of rest. The sealing element and the pressure chamber are constructed such that when the sealing element is in the position of rest there is no connection between the roller and walls of the pressure chamber, and when the sealing element is in the sealing position there is a pressure-tight connection between the walls of the pressure chamber and the roller. | 03-31-2011 |
20100215472 | DEVICE AND METHOD FOR DEPOSITING CONTINUALLY STACKED FLAT MATERIAL PIECES - A process for depositing stacked flat material pieces involves receiving the flat material pieces as a stack on a depositing surface in a receiving position, upon achieving of a predetermined number of stacked flat material pieces on the depositing surface, moving an auxiliary depositing surface out of a rest position to a working position, whereby stacking of the stack of flat material pieces on the depositing surface is terminated and a new stack of flat material pieces is formed on the auxiliary depositing surface, moving the depositing surface into a delivery position in which the stack of flat material pieces arranged on the depositing surface is delivered, moving the depositing surface into the receiving position, during which the new stack of flat material pieces then arranged on the auxiliary depositing surface is taken by the depositing surface and further stacked, and moving the auxiliary depositing surface into the rest position. | 08-26-2010 |
20100089006 | METHOD AND DEVICE FOR MARKING PALLETS - A method for marking a pallet loaded with stacked goods includes fastening at least one marking element having information relevant to the marking to an intermediate layer, and disposing the intermediate layer between two layers of stacked goods during loading of the pallet. The marking element is fastened to the intermediate layer by a positive connection created by deforming the intermediate layer and the marking element. | 04-15-2010 |
20090139838 | APPARATUS AND METHOD FOR SPATIALLY ORIENTING BLANKS - A device for spatially orienting blanks having a length in a transport direction has at least one stop roll body rotatable about a rotation axis and having at least one stop element, and a driver transport system for driving the blanks relative to the stop roll body. The driver transport system has at least one driver roller that pushes the blanks against the driver transport system, and at least one roll body roller that pushes the blanks against the stop roll body, wherein the roll body roller is prestressed in contact with the stop roll body. The driver transport system is a transport belt system having at least one endlessly revolving transport belt. The driver roller is mounted such that path spacing between the roll body roller and the driver roller are set to the length of the blanks. | 06-04-2009 |
