Definitions

  • the present invention relates to a mobile spreader-entry input carriage and a crosslapper equipped with said carriage.
  • the invention aims, in a mobile carriage spider-lapper input, flipping a web or fiber product equivalent, with its transfer between a moving arrival conveyor belt full (as opposed to breathable) and a solid mobile receiving mat.
  • the reversal of the veil is performed in a carriage moving back and forth said entry trolley.
  • the veil is guided on a carpet full of arrival making a U-turn to start in the opposite direction and a carpet full receiver comes back to the veil after flipping and pinching against the first full carpet.
  • the length of the pinch area can be modified by moving the carriage back and forth. This allows to absorb the gap between the continuous arrival of the veil on a solid carpet and the unwinding of the veil from a moving output carriage back and forth above a perpendicular receiving plate moving continuously and on which is formed the web constituted by the folded web.
  • patent EP 0 517 563 it has been proposed as a solution of guide in the mobile entrance trolley the veil on an inclined section of carpet before approaching the turn, so that this turn is less than 180 °, and also to create a line of nipping of the veil in the bend between full mat of arrival and receiver thanks to an appropriate arrangement of guide rollers of the full conveyor belt.
  • the present invention aims to propose another solution again which allows an improvement of the stability of the transport of a veil or equivalent product at the time of its reversal before to be supported in reverse by the receiving mobile carpet.
  • the air contained in the veil has the possibility to escape radially instead of escaping laterally. This has the effect that the veil does not undergo floating disturbing its homogeneity and its transport.
  • the veil is correctly controlled during its reversal in the mobile carriage of entry of the spreader-lapper, this which makes it possible to increase the speed of movement back and forth of the carriage without deforming the veil and thus increasing the speed of production of tablecloth.
  • the better control of the sail makes it possible to reduce its stretching in the crosslapper to maintain at the exit of the crosslapper the quality of the veil provided by the card.
  • conservation the weight of the veil provided by the card makes it possible to reduce the number of folds of the tablecloth and also increase production. This is particularly interesting for a condensed veil.
  • the invention makes it possible to coat the sail with the condensation rate adapted to respect the MD / CD (resistance sense machine / transversal direction) desired while maintaining the quality of the tablecloth final and increasing the productivity of the facility.
  • the fact of letting the air escape radially according to the invention can by elsewhere have an additional effect of consolidation on the veil in causing compaction or even interlacing of fibers. So out of the spreader-lapper the web may be less thick than in the state of the technique, which facilitates the entry into a next machine, for example in a needling machine.
  • the consolidation of the veil also has the effect advantageous to reduce the frequency of machine cleaning since fibers are better held in the veil and do not scatter in the machine.
  • the air is evacuated radially inward of the curvature corresponding to the upturn of the veil, the air-permeable means being constituted for example by a roll whose surface is permeable to air on which the veil is transferred to make it turn around before being put on the carpet receiver.
  • the permeable roll is a roll of maintaining suction, the roller being hollow connected to a suction source.
  • the roller is thus adapted to maintain the veil by suction during its flipping and then releasing it on the receiver mat.
  • deflection means are for example arranged inside the roller aspirant.
  • the guide means of the receiving mats are positioned so that said carpet forms a dam in view of said suction roller to the phenomena of compression and depression due to displacement of said carriage back and forth. This can be important in the case of extreme speeds.
  • the suction roll can be advantageously rotated by coupling with a guide roller belonging to the guide means of the carpet receiver. This makes it possible to bring the veil automatically to the same speed as the receiving carpet.
  • the cylindrical wall of the suction roll can be smooth, that is to say without relief, provided with perforations forming the suction orifices.
  • She can also be conformed with reliefs, such as grooves or staggered holes, so that the suction ports open not directly on the outside of the roll but in at least one chamber depression formed in the cylindrical wall between support zones for the veil. Thanks to this or these depression chambers, the air present in the textile veil is actually sucked radially towards the inside of the roller but the veil remains guided on the support zones without being in contact with suction ports. This eliminates the risks of training and hooking fibers in the suction ports.
  • depression chambers due to their function, are larger larger than the suction ports, which means that the sail area sucked to the right of depression chambers between areas support is increased compared to the state of the art, while retaining for the roller a good mechanical strength.
  • This advantage is important for most applications where the suction roll is a wear part.
  • a perforated fluted roller according to the invention more 90% of the surface of the textile product can be exposed to suction against less than 40% with a conventional perforated roll.
  • the crests of the grooves extend perpendicularly to the direction of the fibers of the web.
  • the flutes can thus be for example circumferential, that is to say perpendicular to the axis of revolution of the roll, axial, that is to say parallel to the axis of revolution of the roll, helical or describing two reverse propellers meeting substantially in the central part of the roller. This last configuration has the additional effect of if necessary, counteract lateral stretching of the veil.
  • the pitch of the grooves or the spacing of the perforations, as well as the depth of the splines or perforations depend on fiber characteristics (length and denier) and shape (holes or slits) and the spacing of the suction ports depend on the intended applications and the density of the veil.
  • the suction is effective only in the active area of the roll, ie in the area passing the veil on the roller where the veil needs to be maintained and guided to avoid its floating. It is defined by means of deflection arranged inside the roll.
  • the means of deflection may include two radial deflectors with possibly one variable angular spacing or an arched deflector possibly from variable arc length telescopically.
  • the roller according to the invention can be manufactured for example from sheet metal which is pierced by appropriate means, and then soda to form the roll, or by spinning, machining or foundry.
  • the material is chosen according to the application, for example a light alloy of aluminum which is then subjected to a surface treatment electrochemical to harden it, or a material based on carbon fibers or steel.
  • the fibers are short and very volatile, can provide to put on the breathable roll a textile sleeve for example knitted or a microperforated thin sheet, the roll bringing the bearing mechanical structure.
  • the air has the possibility of escaping radially outward of the curvature corresponding to the reversal of the veil, said curvature being effected by the veil on the carpet full of mobile arrival, for example around a roller for guiding, and the means permeable to air are constituted for example a convex perforated plating wall disposed opposite said roller guidance.
  • the veil is thus guided in the curvature between said wall of convex perforated veneer and the arrival carpet full to be deposited only when leaving the turn on the receiving mobile carpet.
  • the veil in the curvature, it is under the effect of the centrifugal force that the veil can be plated on the convex perforated wall and not by suction, and the air contained in the web can then escape radially where appropriate through said wall.
  • the perforated wall is consisting of an endless perforated belt continuously moved, of which one zone is adapted to fit the outside of the curvature effected by the veil.
  • Figure 1 shows schematically and partly an example prior art crosslapper in which a transfer takes place sail between two full carpets.
  • the veil 1 arrives continuously on a first full carpet endless 2, then, in a moving entrance cart back and forth 3 where he makes a U-turn to be picked up by a second full mat Endless 4 continuously fed into said carriage 3 with an opposite direction to the arrival direction of the first full carpet 2.
  • the 1 is pinched between the two full mats 2 and 4.
  • the veil 1, and maintained by pinching in a zone P, is then taken up by a second mobile carriage called output 5, whose function is to spread the veil back and forth on an apron 6 moving continuously perpendicular to the moving the output carriage 5 so as to form a tablecloth consisting of staggered folds.
  • the input carriage 3 has the function of rendering compatible, by varying the length of the pinch zone, the arrival continuously the veil on the first carpet 2 with the unwinding of the veil to the output of the output carriage 5, the unwinding varying according to the position of the carriage 5 and the opposite direction or no advance of the carriage 5 relative to the the direction of advance of the web on the carpet 2.
  • the carpet full 2 is guided by two guide rollers 7 and 8 carried by the carriage mobile 3 defining an inclined section 9 so that the sail 1 transported by this carpet then performs around the second roll 8 a turn that is less than 180 °.
  • the path of the second full carpet 4 is defined by four rolls of 10, 11, 12 and 13 carried by the input carriage 3 and arranged on the one hand that a pinch line 14 is formed between the guide roller 8 of the first belt 2 around which the sail 1 performs its turn and one of the guide rollers (11 in Figure 1) of the second carpet 4 and, on the other hand, that the second belt 4 is brought close to the roll 8 to resume the veil 1 at its output.

  • the second solid carpet 4 is guided for its part in the mobile carriage 3 by three guide rollers: the carpet is guided in "S" around an upper roller 41, then around a intermediate roller 42 driven in reverse and then a lower roller 43 bringing the carpet 4 to the appropriate level with respect to the solid carpet 2 for realize the pinching zone P defined between the two mobile carriages entry and exit. All guide rollers are attached to the chassis of the trolley and driven automatically in rotation with the displacement of matching carpet. According to the invention, a suction roller 31, attached to the chassis of the carriage 3, is positioned in front of the inclined portion 24 at a minimum distance from the belt 2.
  • the diameter of the roller 31 and its position are also preferably chosen so that the transfer of the veil 1 on the periphery of the suction roller is substantially tangential and minimizing the vacuum distance d between the intermediate roller 21 and the transfer roller 31 and also for the transfer of the veil of the roller 31 is done then closer in the plane of the second full carpet 4.
  • the rotation of the suction roller 31 is ensured by means of a coupling 44 with the guide roller 42 of the second solid carpet 4, this last being thanks to the configuration in "S” driven in the direction adequate rotation so that the web 1 and the solid carpet 4 arrive in the same meaning after the reversal of the veil and especially advantageously to the same speed.
  • the solid carpet 4 can dam the phenomena of compression or depression due to the displacement of trolley; this can be recommended in extreme cases of speed.
  • the cylindrical wall of the roller 31 is permeable to air and connected laterally to a controlled suction source to maintain the veil during its reversal.
