Definitions

  • the invention relates to a feeding device for advancing fiber material to a collecting device, such as a rotary drum, a collecting belt or product moulds.
  • fiber felt materials are used in a broad range of products for sound insulation for instance in the doors, roof lining and particularly in the floor area. These products are formed and cut to fit the space. Furthermore certain areas of the product contain a higher amount of material to obtain a higher sound insulation. For instance at the underdash extra material is used to reduce noise from the vehicle engine. The added material is also needed in certain areas of the undercarpet or floors to increase the acoustic insulation locally.
  • Felt products can be combined with a heavy layer material to form a spring mass system or with a air flow resistant layer to form an acoustic absorbent system. These products need to have fiber free areas e.g.
  • Fiber-felt products are classically produced from preformed fiber mats containing binder fibers, which are pressed in a heated mould and cut to obtain the desired form and stiffness.
  • a disadvantage of this method is that the grammage of the product depends on the fiber mat and is therefore restricted. Areas with a higher grammage can only be achieved by addtionally supplying the material by hand. This is time consuming and very expensive. Furthermore because the fiber mats are delivered as a roll good or as pre-cut mats the production process is bound to render a lot of scrap material.
  • An other disadvantage of the use of preformed fiber mats is that they easily tear or break when they are pressed in more extreme contoured moulds.
  • the feed tray comprises a plurality of small feed trays which are separately adjustable in their nipping distance to obtain a height profile in the lap formed.
  • the disadvantage of the system is that it can only be adjusted before the production and not during production. Furthermore it only allows a profile in the width of the lap, resulting in a striped profile in the final lap produced. It is not possible to obtain a grammage difference in a local area or to obtain material free areas.
  • EP 770154 discloses a system of at least one filling hose placed above the mould for the loading of the moulds with fiber material.
  • the mould is placed on top of a vacuum air duct to confine the fibers to the mould.
  • the fiber clusters are fed into each hose.
  • Air tubes allow for a stream of air to be used to drive the clusters out of the hose or into the next gated section.
  • a programmable positioning device can be used to manipulate the mould fill hose. It can than be positioned in different areas of the mould and with time the amount of fibers can be regulated in each area. This can also be done with more than one hose per mould.
  • the disadvantage of this system is a complex expensive machinery leaving not much room for a flexible process.
  • the fiber delivering device can be used to produce nonwoven fiber web or laps, to fill moulds or to produce nonwoven fibrous product with a 3 Dimensional shape.
  • the object is achieved by the fiber delivering device according to claim 1 , in particularly by deflecting the fiber flow in the direction of the collection device or in the direction of a recycling device the fibers are not blocked or condensed at any state before the final collection on the collecting device. Furthermore by dividing the width of the machine in small sectors each having means for directing the fiber flow in either the direction of the fiber collecting device for the final product or in the direction of a recycling device for later use of the "discarded" material again, it is possible to deliver fiber material in specific areas of the final product, in specified grammage or even to let out certain areas of the product.
  • the product is not fixed to a mould but can also be in the form of a lap, a 3 Dimensional shaped mat or product. And can either be a continuous fiber material web with a 3 dimensional structure or can be discrete products.
  • a Fiber delivery device comprises fiber feeding means, feeding fiber material via a carding or opening roll to fiber distribution means whereby the fiber distribution means are perpendicular to the collection means divided in a plurality of small fiber distribution means, which are build such that a continuous flow of fiber material can be directed either in the direction of the collection means or in a direction away from the collection means.
  • the small fiber distribution means can be either:
  • the fibers directed away from the collecting device can be directed to an recycling device, preferably in the form of a duct.
  • the collecting means can be a moving perforated belt, or moving perforated plate or moving perforated mould or perforated rotary drum.
  • Vacuum means can be placed underneath the collecting means in line with the position where the fiber material will be placed by the distribution means.
  • the small fiber distribution means are small chutes they can contain at least 2 outlets, one directed to the collecting device and the other outlet directed to a recycling duct and the swivelling flap is located such that at least one of the outlets can be closed.
  • the small chute can contain at least 2 outlets, one outlet directed to the collecting device and the other outlet directed to a recycling duct and the swivelling flap is located such that upon opening of one outlet the other outlet is closed simultaneously.
  • the small fiber distribution means can have each pneumatic attenuation means and can each individually be controlled by a PLC.
  • a first device contains a first main chute with means for feeding fiber material to a second chute feed section.
  • the second chute feed section is in its width divided in sections. These sections are separated with walls to obtain a plurality of small chutes.
  • the feeding means are located just above these small chutes and the material flow is automatically divided in smaller fiber flows due to these separating walls.
  • Each of these small chutes contains two channels, one directed to the fiber collection device and the other directed to a recycling device. At the crossing of the two channels, where the two channels separate to follow different directions, a swivelling flap is located such that it can close at least one of the channels. This swivelling flap can guide the fiber flow either in the direction of the collecting device or away from the collection device in the direction of the recycling device. Instead of channels it is also feasible to have at least 2 outlets.
  • the recycling device can be just a large bin or box for discarding the fiber material, but it can also be a duct system with a ventilator, preferably the duct system is connected with the first main chute.
  • the swivelling flaps are controlled.
  • the swivelling motion can be done by hydraulic or pneumatic means known in the art. These means for the swivelling motion can be controlled and regulated.
  • a computer control system is connected to each of the swivelling flaps, to enable to control the position of the flaps and the timingcard the position has to be changed. By controlling each flap separately it is possible to control the amount of fiber material and the place of the fiber material relative to the product or fiber mat.
  • the width of the collecting device is divided in small areas, the length and width of these areas are dependent on the width and length of the small chutes.
  • the total number of areas in the width direction parallel to the main chute is the same as the total number of small chutes.
  • the swivelling flaps By controlling the swivelling flaps and therefore the direction of the fiber flow it is possible to feed through each small chute "no fibers" or a certain amount of fiber material dependent on the time the fiber flow is directed to the collecting device and the fiber flow rate of the fiber feeding means.
  • the fiber flow rate is defined by the feeding means which delivers fiber material to all small chutes at the same time.
  • the collection device is a continuous moving flat perforated belt and all flaps are set such that the fiber flow is in the direction of this belt, than the result would be a normal nonwoven lap or web with an even distribution of the fibers over the width and length of the web. (length is in the direction of the moving belt).
  • the belt discontinuously in a step wise fashion.
  • the step can copy the length of the small chutes. If the swivelling flaps are then controlled to direct the fiber flow to the collecting device in a discontinuous flow than this can be regarded as portioning of the fiber material.
  • this would mean that it is possible to put discrete portions of fibres material in discrete areas on the belt. Dependent on the step wise movement of the belt these discrete portions are separate or overlap. To create an area without fiber material it is only necessary to direct the fiber material during a certain time period away from the collection device.
  • a second alternative device can have, instead of static small chute with a swivelling flap each to direct the fiber material either to or away from the collecting device, a plurality of ejector nozzles distributed transversely with respect to the direction of travel of the collection device, whereby each of the ejector nozzle is movable between a first position in which said nozzle sprays fibers onto said collecting device and a second position in which said nozzle sprays fibers away from said collecting device.
  • the device for producing a web of nonwoven fibers comprises a recycling device for recycling fibers sprayed by ejector nozzles that are in the second position.
  • the device for producing a web of nonwoven fibers advantageously comprises a reprocessing device for returning fibers recycled by the recycling device to the fiber feed device.
  • the invention also provides a process for producing a web of nonwoven fibers, comprising:
  • a step of moving a collecting device past a fiber feed device comprising a plurality of ejector nozzles distributed transversely with respect to the direction of travel of the ⁇ collecting device;
  • steps of movement between a first position in which the fibers are sprayed onto said collecting device and a second position in which the fibers are not sprayed onto said collecting device and vice versa steps of movement between a first position in which the fibers are sprayed onto said collecting device and a second position in which the fibers are not sprayed onto said collecting device and vice versa.
  • each step of movement between the first position and the second position is followed by a fiber recycling step.
  • fibers recycled in the fiber recycling step undergo a step of transportation to the fiber feed device.
  • the invention also provides a web of nonwoven fibers produced by a production process according to one of the preceding variants.

  • the fibre distribution device comprises an main chute (1) for storing the fibre material.
  • This chute can have the usual appliances for obtaining an homogeneous fibre mass as known in the art, like for instance a back wall, which moves back and forth, or a perforated back wall with an aeration system (not shown).
  • the homogenous fiber mass is than fed to a carding- or opening roll (3) by two feeding rolls (2).
  • Other feeding means for transporting fiber material known in the art like for instance a feeding roll - tray combination, can also be used.
  • the carding or opening roll is used for the final dedensification of the fiber mass. Normally the fibers are delivered in compacted fiber bales. Therefore the fibers are more in clusters than lose fiber material.
  • the opening roll opens these clusters, giving a more even fiber material. Furthermore it is possible to mix binder fibers with the basic fiber material. Then the carding- opening roll functions additionally as a mixing device.
  • the loose fiber material is thrown from the carding roll into the lower chute (10).
  • This lower chute is in the width of the machine divided in smaller section (9), each section is separate from the neighbouring section with a wall, forming in a plurality of small chutes.
  • Each of these chutes (9) has at least 2 outlets one is connected to the recycling duct (5) and the second outlet (6) is directed to a collecting device, here in the form of a perforated moving belt (8) with a suction device (7) underneath the belt, placed directly opposite the outlets (6) of the small chutes.
  • the collecting device moves in a direction perpendicular to the width (W) of the fiber delivery device, this direction is called the length of the fiber web or the product produced.
  • W width
  • L length of the fiber web
  • a swivelling flap (4) is situated between the two outlets (5, 6) such that it can guide the fiber stream either in the direction of the recycling duct (6) or in the direction of the collecting device (5).
  • the flap is mounted to the upper wall of the duct and can swivel such that the channel to the recycling duct is open or closed.
  • the recycling duct is connected to a ventilator to obtain a suction power evenly spread over the whole width of the channel. If the flap opens the channel to the recycling duct this suction power will be such that the fibers released from the carding roll are sucked into the channel instead of falling into the outlet duct directed to the collecting device.
  • the flap closes the channel to the recycling duct the suction power is stopped and the fibers will fall/are directed into the duct or outlet directed to the collecting device.
  • the flap can be situated in the corner between the outlet directed to the recycling duct and the outlet directed to the collection device (figure 3) in this situation the swivel point is in the middle of the flap, at the same time opening one duct and closing the other duct.
  • each of the flaps is connected to its own pneumatic means for controlling and making the swivelling movement of the flap.
  • the fibers will be gathered on a collecting device (8).
  • This can be a moving perforated belt (as shown) or a rotary drum.
  • the surface of the collecting device can be either flat or have a surface in the form of moulds. Underneath the collecting surface located directly under the fiber delivering device a vacuum duct (7) is placed to keep the fiber material on the collecting surface and prevent the fibers from being blown away.
  • the carding roll has a saw tooth wire with large tooth (11).
  • the saw tooth is placed such that it function as a screw and pushes the fiber material to side making an easy and even access to the small chutes possible.
  • the control of the direction of the fibre stream has the advantage that a discrete amount of fiber material can be placed on a specific part of the surface of the collecting device.
  • a fiber distribution device divided in X smaller chutes over the total width of the machine, would equal X discrete areas on the collection device underneath the outlets, where a discrete amounts of fiber material can be dropped.
  • Over the width each of the flaps can be set separately to either distribute the fibers to the collecting device or to the recycling duct, therefore of the X positions there can be certain which are empty or which receive an amount of material.
  • Figure 7 show a typical controlling plan for the step wise production of a 3 dimensional product.
  • the total area of the collecting device is divided in small square whereby each square equal the width W and length L' of the small chutes. If a square is empty this is to indicate no fiber material, and corresponds to a signal to the analogue small chute flap to direct the material away from the collecting device for instance to the recycling device.
  • the amount of fiber material is given in each square where material is needed, this corresponds to the time the material flow is directed to the collecting belt.
  • each row is achieved by a stepwise movement of the collecting device.
  • This stepwise movement is dependent on the length of the small chutes, the amount of overlap of the rows needed.
  • a stepwise movement occurs, is dependent on the time a row needs, which is dependent on the time needed by a small chute to deliver the largest amount of fiber necessary in that row.
  • Figure 4 shows an example of web of nonwoven fibers 220 bounded by an outline 402 that includes a re-entrant portion 408, a hole 404, and a reduction in thickness 406.

  • the collecting device 208 is supplied with fibers by the fiber feed device 124. It is movable relative to the fiber feed device 124 and contains perforations. The collecting device 208 moves in the direction represented by arrow 210. The movement of the collecting device 208 distributes the fibers so that they do not accumulate in one place. In another embodiment the collecting device 208 could be stationary while the fiber feed device 124 moves. The suction device is designed to draw air through the perforations and so press the fibers against the collecting device 208. This device can be the same for both alternative solutions.
  • the feed device 124 comprises a plurality of ejector nozzles 230a, 230b distributed transversely perpendicular) with respect to the direction of travel 210 of the collecting device 208 and each ejector nozzle 230a, 230b is movable between a first position
  • Each nozzle 230a, 230b can therefore position itself in either the first or second position, and can do so independently of the others.
  • Each ejector nozzle 230a which is in the first position sprays fibers onto the collecting device 208 and each ejector nozzle 230b which is in the second position sprays fibers away from the collecting device 208.
  • only fibers sprayed by ejector nozzles 230a which are in the first position reach the collecting device 208 and agglomerate to form the web of nonwoven fibers 220.

That face of the web 220 which is against the collecting device 208 is flat, while the other face of the web 220 exhibits variations of height, each corresponding to a variation of thickness of the web
  • Fig. 6 shows a web 220 comprising a reduction in thickness 310 brought about by positioning the corresponding ejector nozzle in the first position for a certain period and in the second position after the end of this period.
  • the speed of travel of the collecting device 208 and the flow rate of the fibers through the ejector nozzles 230a, 230b must be matched to each other in such a way as to produce the maximum desired thickness.
  • the speed of travel of the collecting device 208 is made dependent on the fiber flow rate in order to achieve a preferred fiber grammage on the collecting device 208.
  • Webs 220 of variable widths can also be produced by setting the outer ejector nozzles in the second position.
  • the reduction in thickness 406 is achieved by spraying fibers for a period less than that necessary to produce a greater thickness through the ejector nozzle or nozzles located approximately in the center of the collecting device 208.
