The transport process of front sliver AS flow chart as shown in Figure 2.Front sliver AS in VA step on last drying drum TZn leave line AL after from dry zone 3, take off, and towards functional unit 4, transmit in method step VB, shown in leave line also with the dry zone 3 of drying drum TZn to leave line consistent.After completing transhipment, can full width operation according to step VC fibrous cloth width F.Method shown in Fig. 2 is described the transport process of pure front sliver AS at this.Fig. 1 is clear and definite for the necessary device of transport process of front sliver AS, especially attach troops to a unit in the pick device 8 that leaves the dry zone 3 after line AL on drying drum TZn and continue if desired the device of guiding, and for example conveyer belt 9.
And Fig. 3 illustrates according to designing for realizing the configuration of transport process after there is interference in whole unit shown in Fig. 1.For identical parts, with identical accompanying drawing, represent, and structural design is with reference to figure 1.Fig. 4 illustrates each method step.
According to method step V0, when the variable that is identified at the disturbed condition in machine when operation or the result of harmful operation being detected, by fibrous cloth width from gathering-device, especially derive the region before interference source in pulper, and fibrous cloth width is put into operation again.Because fibrous cloth width F is generally transported with whole width between each functional unit of machine, so the front sliver AS ' preferably manufacturing with the form of edge strip can until fibrous cloth width again with whole width broadenings mobile, described front sliver is guided through the functional unit of each arranged in succession of machine.If this front sliver AS ' in drying device 1 by being arranged in this way guiding for guiding the suction roll 6 of dry zone 3 after last drying drum TZn, according to method step V01, this front sliver is not to force to be transported on functional unit 4 subsequently at once, but direct in the gathering-device that is arranged in drying device 1 below, especially in pulper 18.Described guiding is carried out preferably wirelessly.For this purpose, in last drying drum TZn and the region between suction roll 6 with in also having the region between the guide roller 19 of preferably guiding dry zone 3 after suction roll and suction roll 6, load with negative pressure, preferably load with vacuum.This loading can by be arranged on the inner side 14 of dry zone 3 and after suction roll 6, for applying the device 21 of negative pressure, realize.Guide roller 19 is arranged in suction roll 6 belows.Their longitudinal axis of arranging of being mutually separated by vertical direction can align in vertical direction, in MD direction, do not misplace and arrange.Guide roller 19 preferably has the diameter less than suction roll 6, thereby dry zone 3 is with respect to angularly guiding between suction roll 6 and guide roller 19 of vertical direction, to can make the front sliver AS ' in pulper 18 derive simply.Device 16 and 21 can also form a unit.In order not injure adjacent domain on the required region in drying device 1 targetedly, negative pressure is not set, described region preferably with respect to the external environment condition sealing of surrounding this region, for example, seals by corresponding cover plate 20.
After before guaranteeing guiding, sliver AS ' enters pulper 18, in method step V02, using expectation width broadening movement as the fibrous cloth width of fibrous cloth width F '.Institute's broadening or at the fibrous cloth width F ' of end full width broadening, be similarly bearing on dry zone 3 in method step V03 to pulper 18 guidings.At this, the negative pressure of fibrous cloth width F ' charger 16 on suction roll 6, in order to be retained on dry zone until in suction roll 6 leaves and enters the region between suction roll and guide roller 19 being arranged in after suction roll.At this, by broadening mobile fibrous cloth width F ' in V04, be divided into before the method for sliver AS and residue breadth RS, manufacture front sliver AS originally.Residue breadth RS is imported into pulper V05, and according at the VA to VC shown in Fig. 2, front sliver AS being transported to rearmounted functional unit 4, and fibrous cloth width F with the width broadening of hope mobile.Subsequently, the mobile fibrous cloth width F in broadening ground is no longer directed to the picking region AB on suction roll 6 in VD, but before dry zone 3, is just removed according to the virtual connecting line with rearmounted functional unit, for example conveyer belt 9.Mark is carried out with 24 in this region, and be preferably placed at dry zone hold suction roll 6 hold the picking region AB of inherence, region for front sliver AS before.The fibrous cloth width F moving represents with chain-dotted line the broadening of transporting.
In order to cut apart fibrous cloth width F ' for front sliver AS and to remain breadth RS, segmenting device 17 is set, this device can be at the interior front sliver AS that fibrous cloth width F ' is divided into residue web RS and treats again to put into operation, flow to functional unit 4 of drying device 1.According to the embodiment shown in Fig. 3, before the direction of transfer of dry zone 3 and fibrous cloth width F to the traffic direction of last drying drum TZn, especially cut apart described in carrying out between slewing rollers 5 and drying drum TZn.
Segmenting device 17 can be designed to different types.Can also consider to spray with liquid form, for example double end water the cutting medium of cutting machine, also have solid form, for example cutter.According to design and position, the width of front sliver and the position of front sliver in CD direction can change.Especially when segmenting device is designed to double end cutter sweep, there is this possibility that affects independently the width of position in cross-machine direction and front sliver.
