20080256757 | APPARATUS AND METHOD FOR DEPOSITING SYNTHETIC FIBERS TO FORM A NONWOVEN - The invention relates to an apparatus and a method for depositing synthetic fibers to form a nonwoven, in which the synthetic fibers are blown through a take-up nozzle as a fiber stream in a free space in the direction of a deposit belt. According to the invention, the fiber stream, before impinging onto the deposit belt, is guided by a guide segment formed between two guide members, one of the guide members being arranged on a belt exit side and an opposite guide members being arranged on a belt inlet side and forming, at a distance from the take-up nozzle, an open fiber entry gap for entry into the guide segment, and the guide segment extending as far as the deposit belt. | 10-23-2008 |
20080311816 | METHOD AND APPARATUS FOR STRENGTHENING A RUNNING NON-WOVEN WEB, AND A NON-WOVEN WEB - The invention relates to a method and an apparatus for strengthening a running non-woven web. For this purpose, the non-woven web is penetrated by a plurality of fluid streams. In order to create a surface structure, the fluid streams are generated by a movable nozzle beam, which is guided back and forth at a defined amplitude substantially transversely to the running direction of the non-woven web. In order to obtain enough flexibility and a sufficient volume in the non-woven web in spite of the strengthening effect, the amplitude for moving the fluid streams back and forth is selected in such a way according to the invention that the points of impact created in the non-woven web by adjacent fluid streams do not intersect an imaginary separating line in the running direction. To this avail, the amplitude of the back and forth movement of the nozzle beam is adjusted so as to be smaller than half the distance between two nozzle outlets disposed next to each other in the row. | 12-18-2008 |

20140344479 | METHOD FOR TRANSFERRING DATA BETWEEN A POSITION-MEASURING DEVICE AND AN ASSOCIATED PROCESSING UNIT AND POSITION-MEASURING DEVICE THEREFOR - A method for transferring data between a position-measuring device and an associated processing unit includes transferring first data having a first priority in successive cycles from the position-measuring device to the processing unit. The successive cycles are in each case initiated by a request command by the processing unit requesting the first data from the position-measuring device. Second data having a second, lower priority is transferred from the position-measuring device to the processing unit in at least a portion of the successive cycles with the first data. Types of the second data being transferred in a respective one of the successive cycles are variable. At least one particular type, of the types of the second data to be transferred, is assigned to individual cycles of the successive cycles using information stored in the position-measuring device without involvement of the processing unit. | 11-20-2014 |
20150088450 | POSITION-MEASURING DEVICE AND METHOD FOR TESTING A CLOCK SIGNAL - A position-measuring device includes a position-sensing unit, a processing unit, an interface unit, a clock generator and a time measurement unit position-sensing unit configured to generate digital position values. The processing unit processes instructions from subsequent electronics. The interface unit communicates with the subsequent electronics, according to rules of an interface protocol, via at least one interface line that transmits interface signals having a temporal behavior that is determined by the interface protocol so as to transmit the instructions from the subsequent electronics to the processing unit. The clock generator generates a clock signal that serves as a time base for functions of the position-sensing unit and the processing unit. The time measurement unit uses the clock signal as a time base, receives at least one interface signal and measures a time interval between a start event and a stop event of the at least one interface signal. | 03-26-2015 |
