摘要： A fiber sliver producing apparatus includes an arrangement for making a running fiber web and a web gathering device which has a plurality of walls defining an inner space through which the fiber web runs in an advancing direction. The walls are stationary during operation of the apparatus. The web gathering device has a web gathering portion causing the running fiber web to converge and a web densifying portion, situated downstream of the web gathering portion as viewed in the advancing direction, for forming a running sliver from the web. The web densifying portion has an outlet opening of cross-sectionally rectangular outline and an opening width which is at least five times greater than the opening height. Upon discharge through the outlet opening, the sliver passes through cooperating rolls of a calender roll pair defining a bight in which the outlet opening of the web gathering device is disposed.

摘要： In an apparatus and a process for preparing a flock-air mixture which is fed by a pulping device through a feed conduit to a flock-laying device for forming an absorbent pad, the feed conduit includes a dispersing device for loosening up lumps of flock within the mixture. To achieve a high level of efficiency in loosening the flock lumps, as independently as possible of the through-put of the mixture through the feed conduit, the dispersing device is in the form of a pneumatic dispersing device which loosens up the lumps by accelerating the mixture with lumps therein to cause the lumps to burst or tear apart.

摘要： An extensible apertured nonwoven web, and a method for making such an apertured nonwoven web. In one embodiment the method comprises the steps of providing an apertured nonwoven web, incrementally stretching it in a direction substantially parallel to the cross machine direction, and applying tension in the machine direction such that the web width after applying tension is less than the web width after incremental stretching. In another embodiment the method comprises the steps of providing a nonwoven web; weakening the nonwoven web at a plurality of locations to create a plurality of weakened, melt-stabilized locations; applying a first tensioning force to the nonwoven web to cause the nonwoven web to rupture at the plurality of weakened, melt-stabilized locations creating a plurality of apertures in the nonwoven web coincident with the weakened, melt-stabilized locations, incrementally stretching the nonwoven web in a direction substantially parallel to the cross machine direction, and applying tension in the machine direction such that the web width after applying machine direction tension is less than the web width after incremental stretching. An apparatus for producing a web of the present invention by this method is also disclosed. The extensible apertured nonwoven web produced has a plurality of apertures each having a hole size greater than 2 mm2, and a hole aspect ratio less than 6, the nonwoven web having an open area greater than 15% and being capable of at least 70% extension in the cross machine direction at a loading of 10 g/cm.

摘要： The method and an apparatus provide for the automatic provision and transfer of a reserve lap (WR) from a reserve position (RP) to a working position (AP) in a machine (K1 to K3) for processing wound laps and for the automatic discharge of an empty tube (H) from the working position (AP). The conveying system (K, 4) is provided to convey wound laps (W) or empty tubes (H) individually or in groups between a lap-processing (K1 to K3) and a lap-forming machine (KV). The control unit (8) of the conveying system (K, 4) is connected with a central control unit (ST) which is connected with the control unit (21, 22, 23) of the respective lap-processing machine (K1 to K3), with a conveyor (T) in the lap-forming machine (Ky), as well as with the control unit (20) of the lap-forming machine (Ky), and a transfer device (58, 60, 61, 63) which can be controlled via the control unit (21,22,23) of the respective lap-processing machine (K1 to K3).

摘要： An apparatus and a method for preparing an absorbent article is disclosed. The apparatus has at least two forming surfaces which differ in terms of air permeability to allow the selective placement of fibrous material. The forming surface comprises a perforated forming screen. The forming screen has multiple zones with different amounts of open area through which air may pass. Particles carried in the air which flows through the open area are deposited on different zones of the forming screen resulting in different basis weights corresponding to the different air permeabilities. The apparatus and method thus provide an article having optimal zoned absorbency in a cost-effective manner.
摘要翻译：公开了一种制备吸收制品的装置和方法。该装置具有至少两个在透气性方面不同的成形表面，以允许纤维材料的选择性放置。成形表面包括穿孔成形筛。成型筛具有多个具有不同量的开放区域的区域，空气可通过该区域通过。在空气中携带的流过开放区域的颗粒沉积在成形网的不同区域上，导致与不同透气度相对应的不同基重。因此，该装置和方法以成本有效的方式提供具有最佳分区吸收性的制品。
