20150259836 | METHOD FOR HOMOGENIZING THE STITCHING PATTERN IN A NEEDLED FLEECE - A method for homogenizing the stitching pattern in a needled fleece requires a detector which is arranged between a first needling device and a second needling device and detects areas in the fleece where stitches are absent. Then the fleece needled by the first needling device is also needled in the second needling device, wherein at least one operating parameter or at least one structure parameter of the second needling device is adapted specifically on the basis of the result of the detection of the absent-stitch areas, so that, during the further needling of the fleece in the second needle machine, the absent-stitch areas are filled in a targeted manner. | 09-17-2015 |
20130014349 | Method for Operating a Fleece LayerAANM Dilo; Johann PhillippAACI EberbachAACO DEAAGP Dilo; Johann Phillipp Eberbach DE - The method for operating a fleece layer requires a fleece layer, to which the card web is supplied at variable card web infeed speed. To limit the amount of space required for the upper carriage at the rear of the machine, the average of the absolute values of the laying-carriage speed during the forward movement of the laying carriage in at least some laying cycles differs from the average of the absolute values of the laying-carriage speed during the return movement of the laying carriage, and the average of the absolute values of the laying-carriage speed in at least some laying cycles during the forward movement of the laying carriage differs from twice the average of the absolute values of the upper-carriage speed during the forward movement of the laying carriage. | 01-17-2013 |
20120180265 | Fleece Layer - The fleece layer for laying down a card web to form a fleece has a cross-lapping upper carriage, through which the card web is guided; a cross-lapping laying carriage, through which the card web coming from the upper carriage is guided and which serves to lay the card web down onto an output conveyor belt, and at least two card web conveyor belts for guiding the card web to the upper carriage and from there to the laying carriage. An upper run of a first endless card web conveyor belt extends from the infeed area of the fleece layer to the upper carriage and serves as a support surface for the card web. A positionally variable pressing means is provided, which can be actuated to produce a variable card web buffer in the upper run of the first card web conveyor belt. | 07-19-2012 |
20120180264 | Fleece Layer - The fleece layer for laying down a card web to form a fleece has a cross-lapping upper carriage, through which the card web is guided; a cross-lapping laying carriage, through which the card web coming from the upper carriage is guided and which serves to lay the card web down onto an output conveyor belt; and at least two card web conveyor belts for guiding the card web to the upper carriage and from there to the laying carriage. A cover belt is arranged to enclose the card web lying on the upper run of a first card web conveyor belt from above. The cover belt is smooth and is not moved when the card web is moved, thus serving as a stationary cover of the card web. | 07-19-2012 |
20100162543 | Needle Board for a Needle Machine - The needle board for a needling machine has a base plate with a plurality of receptacles, and a plurality of needle modules. Each needle module has a carrier plate which is equipped with a plurality of needles arranged in a predetermined pattern and which is inserted into one of the receptacles in the base plate in such a way that the needles project from the base plate. | 07-01-2010 |
20100084248 | Device and Method for Transferring Nonwoven Material - A device for transferring nonwoven material from a fleece-laying machine to a consolidation device having an endless circulating output conveyor belt of the fleece-laying machine for accepting card webs which are laid on the output conveyor belt from above by the fleece-laying machine, the laid card webs forming the nonwoven material. A first drive unit drives the output conveyor belt at variable speed. In addition, a second drive unit for driving the output conveyor belt at an essentially constant speed is provided at a point which, relative to the first drive unit, is closer to the consolidation device. A hanging storage buffer of the output conveyor belt is thus formed in a section of the output conveyor belt located between the first drive unit and the second drive unit. | 04-08-2010 |
20100043179 | Fleece-Laying Device - A fleece-laying device for laying a fleece from a card web having a laying carriage movable above and transversely to an output conveyor belt, an upper carriage also movable transversely to the output conveyor belt, and a first card web conveyor belt and a second card web conveyor belt for guiding the card web via the upper carriage and the laying carriage into a laying nip formed in the laying carriage. The fleece-laying device includes a card web guiding area between the upper carriage and the laying carriage with two sections of the first and second card web conveyor belts holding the card web between them and being guided over at least one support roll mounted in a support carriage which is also movable transversely to the output conveyor belt. | 02-25-2010 |
20090143208 | Hollow Roll - A hollow roll which includes a roll body closed off at each end by a plug-like end piece inserted with a precise fit into the roll body is provided. Each end piece includes an attached axially projecting journal to provide rotatable support for the hollow roll and each end piece has at least one meandering-like or substantially spiral groove in the part of its circumference which is seated in the roll body. The groove is closed off from the cavity of the roll and comprises a connection to the outside at each of the two ends of the groove which is completely filled with an adhesive. | 06-04-2009 |
20090064464 | Device for Compacting Fiber Flocks - A device for compacting fiber flocks into a flock mat has means for supplying the fiber flocks, a discharge belt for carrying the compacted flock mat away, and walls, which are arranged opposite each other between the means for supplying the fiber flocks and the discharge belt and thus form the boundaries of an essentially vertical chute feed, which defines the transport direction of the fiber flocks. At least one of the walls is supported in such a way that its movement during each cycle has a component in the transport direction of the fiber flocks and a component in the direction transverse to the transport direction. | 03-12-2009 |
20090038129 | Device and Method for Needling a Nonwoven Web - A device for needling a nonwoven web includes several needle looms arranged in series, each with at least one needle bar, a pair of infeed rollers, and a pair of outfeed rollers. The needle looms can move along a guide in the transport direction of the nonwoven web and can be locked in place at any desired distance from each other. | 02-12-2009 |
20090017711 | Method of Manufacturing a Nonwoven - In the production of a solidified nonwoven web by crosslaying a card web produced with a uniform transverse profile by a card web forming device and then by consolidating the crosslaid nonwoven web thus formed, the basis weight of the solidified nonwoven web or of the crosslaid nonwoven web is measured only in the middle and in the area of at least one of its edges, and the basis weight of the card web to be laid is locally changed on the basis of a comparison of the measurement values with the nominal values preestablished by the laws, previously described for the nonwoven web to be produced, governing the structural change in the product caused by solidifying. | 01-15-2009 |
20080313860 | Apparatus and Method for Feeding Fibers - A feeding device for fiber flocks or opened fibers for feeding a textile machine, especially a carding machine, has a first, upper vertical fiber chute which supplies the fibers or fiber flocks to rolls for opening of the fibers, and a lower fiber chute which accepts the fibers released by the rolls and discharges a fiber mat at the bottom end of the fiber chute by way of discharge rolls. The feeding device also has a segmented intake trough with several intake trough segments which cooperate with a segmented, clothing-covered first roll, which is divided into several roll segments, wherein the torque of the roll segments can be controlled individually and the widths of the gaps between the intake trough segments and the associated roll segments can be adjusted on a segment-by-segment basis. | 12-25-2008 |
