- the aforesaid intermediate conveyor means include:
- the upper randomized web is released by the doffer cylinder (4) onto the active portion (5a) of the main conveyor belt and passes in succession through the two adjacent portions, which are inclined to each other, of the main and auxiliary conveyor belts before being deposited on the final conveyor belt (15).
- the web carried by the horizontal active portion (5a) of the main conveyor belt (5) is controlled, at the beginning and at the end of this horizontal portion; by two finned control cylinders (6, 11), the first of which (6) is adjacent the doffer (4) and is associated with a flap (9) intended to control the abrupt difference in pressure which occurs when the web is released by the doffer (4).
- the randomized web has no cohesion and so, in those sections where the surface is free and in those sections where it changes in inclination, it tends to return from the randomized configuration back to the initial configuration it had when leaving the combing cylinder, in which configuration the fibres were all parallel to the direction of advance.
- the present invention provides a carding machine for preparing randomized webs for non-woven fabrics having the characteristics stated in Claim 1.
- the final swift of a carding machine is rotatable clockwise, while two output combing cylinders, indicated 2a and 2b, are arranged at different heights and are both rotatable anti-clockwise.

- the upper randomized web is conveyed by the two conveyor belts 8 and 9 without any loss of randomization, thanks to the perforation of the lower belt 8 and to the set of radial fins of the cylinder 8a, which enable discharge of the air turbulence produced by the cylinders rotating at high speed.
- the upper randomized web is deposited on the lower randomized web carried by the final conveyor belt 6 downstream of the oblique-finned cylinder 7, after which an oblique-finned cylinder 11 acts on the two webs arranged one on top of the other in order to prevent any loss of randomization of the two webs before these enter the homogenization unit.

- the carding machine according to the variant illustrated in Figure 2 differs from that of Figure 1 in that two randomiser cylinders 3 and 3a are arranged in series between the upper combing cylinder 2b and the upper doffer cylinder 4 instead of the single randomiser cylinder 3 shown in Figure 1.

Description
- The present invention relates to a carding machine for preparing randomized webs for non-woven fabric.
- In particular, the invention relates to a carding machine of a type used in the wool industry and which includes:
- a final swift,
- at least two combing cylinders arranged at different heights, each operable to take from the said final swift a web of fibres predominantly orientated along a direction parallel to the direction of advance of the web,
- a randomiser cylinder which releases by condensing a thicker web of randomized fibres taken from each combing cylinder,
- a doffer cylinder which takes a randomized web from each randomiser cylinder,
- a final, perforated conveyor belt which supplies a homogenization unit with randomized webs coming from each doffer cylinder and arranged one on top of the other,
- intermediate conveyor means for conveying to the final conveyor belt the web leaving the doffer cylinder or cylinders which process the webs coming from the combing cylinders positioned at greater heights than the lowest combing cylinder,
- a plurality of finned cylinder, each driven by a variable-speed motor, which control the web along its path between a doffer cylinder and the final conveyor belt,
- the intermediate conveyor means include a pair of continuous conveyor belts the active portions of which are one above the other and adjacent.
- A carding machine of the type described above is known from the European Patent Application 1 046 731 by the same applicant.
- In the carding machine with two combing cylinders, described with reference to Figure 2 of the aforesaid document, as far as the upper combing cylinder (2) is concerned, the aforesaid intermediate conveyor means include:
- a main conveyor belt (5) with a horizontal active portion (5a) and an inclined active portion (5b),
- an auxiliary conveyor belt (12) having an active portion of which only the central section is adjacent to the inclined portion (5b) of the main conveyor belt (5) under the action of an adjustable cylinder (13).
- The upper randomized web is released by the doffer cylinder (4) onto the active portion (5a) of the main conveyor belt and passes in succession through the two adjacent portions, which are inclined to each other, of the main and auxiliary conveyor belts before being deposited on the final conveyor belt (15).
- The web carried by the horizontal active portion (5a) of the main conveyor belt (5) is controlled, at the beginning and at the end of this horizontal portion; by two finned control cylinders (6, 11), the first of which (6) is adjacent the doffer (4) and is associated with a flap (9) intended to control the abrupt difference in pressure which occurs when the web is released by the doffer (4).
- Although the known arrangement described above constitutes substantial progress compared to the prior art, it does not fully solve the problem of maintaining at high speed the high degree of randomization of the web released by the doffer cylinder, while the web is being conveyed from the doffer cylinder to the final conveyor belt which leads to a cohesion-inducing station.
- In fact, the randomized web has no cohesion and so, in those sections where the surface is free and in those sections where it changes in inclination, it tends to return from the randomized configuration back to the initial configuration it had when leaving the combing cylinder, in which configuration the fibres were all parallel to the direction of advance.
- This phenomenon of loss of randomization also occurs, though to a small extent, with the carding machine according to the aforementioned document, in which the surface of the web is free between the two
finned control cylinders 4, 11 arranged at either end of the horizontal active portion and undergoes a considerable change in inclination when passing from this horizontal active portion to the inclined active portion of the main conveyor belt. - In order to eliminate the above problem, the present invention provides a carding machine for preparing randomized webs for non-woven fabrics having the characteristics stated in Claim 1.
- Further characteristics are claimed in the subsequent Claims.
- The invention will now be described with reference to the appended drawings, provided purely by way of non-limitative example, in which:
- Figure 1 illustrates a carding machine with two combing cylinders according to the invention,
- Figure 2 shows a variant of the machine of Figure 1, and
- Figure 3 shows a carding machine with three combing cylinders.
- With reference to Figure 1, the final swift of a carding machine, indicated 1, is rotatable clockwise, while two output combing cylinders, indicated 2a and 2b, are arranged at different heights and are both rotatable anti-clockwise.
- The
lower combing cylinder 2a takes a lower web, constituted by fibres orientated parallel to the direction of advance, from the cylinder 1 in a known manner. - In a known manner, a randomiser
cylinder 3 rotating clockwise takes a first web of randomized fibres, that is, fibres distributed according to a statistically random pattern, from the combingcylinder 2a. - The
cylinder 3 is doffed, in a known manner, by a doffer cylinder 4 rotating clockwise. - The conveying of the randomized fibres from the randomiser
cylinder 3 to the doffer cylinder 4 is controlled by acontrol cylinder 5 which rotates anti-clockwise and is provided with oblique circumferential fins, like the cylinder indicated B in Figures 7 and 8 and described with reference to these figures in the aforementioned European Patent Application 1 046 731. - This set of oblique fins has proved to be particularly effective in conveying and controlling the web of randomized fibres and in conducting the air flows produced by the
cylinders 3 and 4. - The restraining and compressing action exerted on the fibres by the
cylinder 5 prevents the web from being deformed and stretched. - The web leaving the doffer 4 is deposited on a
perforated conveyor belt 6 which conveys it to a web homogenization unit, which is not shown. - The active portion of the final perforated
conveyor belt 6 has an initial section over which is arranged the adjacent active portion of aconveyor belt 13, which moves at the same speed as thebelt 6. Asupport cylinder 6a upstream of theperforated belt 6 has radial fins and the doffer 4 delivers the lower randomized web between thebelts - An oblique-finned
cylinder 7 acts on the active portion of theconveyor belt 6 immediately downstream of theconveyor belt 13. - This arrangement ensures the stability of the randomization of the lower web during the initial path thereof on the
belt 6. - In the same way as described above with respect to the
lower combing cylinder 2a, an upper randomisercylinder 3 takes a web of randomized fibres from the upper combingcylinder 2b and is doffed by an upper doffer cylinder 4. The conveying of the randomized web from thecylinder 3 to the cylinder 4 is controlled by an oblique-finnedcylinder 5, driven by an independent, adjustable-speed motor. - The upper doffer cylinder 4 delivers the upper web between the adjacent portions of two
conveyor belts 8, 9 arranged the one above the other and inclined downwards. The advance speed of these twobelts 8 and 9, which clamp the web between them throughput their length, is the same as the peripheral speed of the doffer cylinder 4. - The
upper belt 9 is airtight, while the lower belt 8 is perforated. Thecylinder 8a, which supports the perforated belt 8 upstream, that is, adjacent to the doffer cylinder 4, is provided with radial circumferential fins like the cylinder indicated A in Figures 3 and 4 of the aforementioned European Patent Application 1 046 731. - An oblique-finned
control cylinder 10 acts on the top surface of the web along the path thereof from the doffer cylinder 4 to theconveyor belts 8, 9, thereby facilitating the insertion of the web between these belts. - The upper randomized web is conveyed by the two
conveyor belts 8 and 9 without any loss of randomization, thanks to the perforation of the lower belt 8 and to the set of radial fins of thecylinder 8a, which enable discharge of the air turbulence produced by the cylinders rotating at high speed. - On leaving the
conveyor belts 8 and 9, the upper randomized web is deposited on the lower randomized web carried by thefinal conveyor belt 6 downstream of the oblique-finnedcylinder 7, after which an oblique-finnedcylinder 11 acts on the two webs arranged one on top of the other in order to prevent any loss of randomization of the two webs before these enter the homogenization unit. - It has been experimentally confirmed that a carding machine having the characteristics described above enables to produce a non-woven fabric which is isotropic once it has been homogenized, that is, a fabric having a longitudinal strength (that is to say, in the direction of advance of the final conveyor 6) is equal or close to the transverse strength thereof.
- The carding machine according to the variant illustrated in Figure 2 differs from that of Figure 1 in that two
randomiser cylinders upper combing cylinder 2b and the upper doffer cylinder 4 instead of thesingle randomiser cylinder 3 shown in Figure 1. - In this case, the randomization of the upper web is performed in two successive stages instead of in one stage only.
- Since the
second randomiser 3a rotates in the opposite sense to that of thefirst randomiser 3, the web is dragged on its top surface by thefirst randomiser cylinder 3 and on its bottom surface by thesecond randomiser cylinder 3a, whereby it moves along a sinusoidal path over these cylinders. Therefore, an upper oblique-finnedcontrol cylinder 5a is used to control the path of the web over thecylinder 3 and a second oblique-finnedcontrol cylinder 12 is used to control the path of the web over therandomiser cylinder 3a. - The perforated lower conveyor belt 8 has a free first active section, that is, a section which is not affected by the active portion of the
belt 9, and the doffer cylinder 4 is arranged over this free section. - In the carding machine according to the variant illustrated in Figure 3, three
combing cylinders - The intermediate combing
cylinder 2b cooperates with a randomisercylinder 3 and the intermediate randomized web leaving therandomiser 3 is delivered by a doffer cylinder 4, with the assistance of an oblique-finnedcontrol cylinder 10, between twoinclined conveyor belts 8 and 9 which deposit it on the lower randomized web carried by thefinal conveyor belt 6. - The upper combing
cylinder 2c cooperates with a randomisercylinder 3 and the randomized web leaving therandomiser 3 is fed to a doffer cylinder 4. An oblique-finned control cylinder 5 controls the passage of the web from thecylinder 3 to the cylinder 4. The doffer cylinder 4 delivers the upper randomized web between twoconveyor belts 14, 15 having the same characteristics as theconveyor belts 8 and 9 described above with reference to Figure 2 - The two
conveyor belts 14 and 15 convey the upper randomized web to the doffer 4 associated with the intermediate web, produced by the randomisercylinder 3 in cooperation with the intermediate combingcylinder 2b. The doffer cylinder 4 associated with the intermediate combingcylinder 2b therefore delivers two webs arranged one on top of the other between theconveyor belts 8 and 9, the webs being deposited by the belts on the lower randomized web conveyed by thefinal conveyor belt 6. - The assembly constituted by the
upper combing cylinder 2b and theelements combing cylinder
