Definitions

  • the present invention relates to a carding machine for preparing randomized webs for non-woven fabric.
  • the invention relates to a carding machine of a type used in the wool industry and which includes:
  • a carding machine of the type described above is known from the European Patent Application 1 046 731 by the same applicant.
  • 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 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.
  • 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 combing cylinder 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 a control 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 a conveyor belt 13, which moves at the same speed as the belt 6.
  • a support cylinder 6a upstream of the perforated belt 6 has radial fins and the doffer 4 delivers the lower randomized web between the belts 6 and 13.
  • An oblique-finned cylinder 7 acts on the active portion of the conveyor belt 6 immediately downstream of the conveyor belt 13.
  • This arrangement ensures the stability of the randomization of the lower web during the initial path thereof on the belt 6.
  • an upper randomiser cylinder 3 takes a web of randomized fibres from the upper combing cylinder 2b and is doffed by an upper doffer cylinder 4.
  • the conveying of the randomized web from the cylinder 3 to the cylinder 4 is controlled by an oblique-finned cylinder 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 two belts 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.
  • the cylinder 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 the conveyor 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 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.
  • 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 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.
  • the randomization of the upper web is performed in two successive stages instead of in one stage only.
  • an upper oblique-finned control cylinder 5a is used to control the path of the web over the cylinder 3 and a second oblique-finned control cylinder 12 is used to control the path of the web over the randomiser 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.
  • the intermediate combing cylinder 2b cooperates with a randomiser cylinder 3 and the intermediate randomized web leaving the randomiser 3 is delivered by a doffer cylinder 4, with the assistance of an oblique-finned control cylinder 10, between two inclined conveyor belts 8 and 9 which deposit it on the lower randomized web carried by the final conveyor belt 6.
  • the upper combing cylinder 2c cooperates with a randomiser cylinder 3 and the randomized web leaving the randomiser 3 is fed to a doffer cylinder 4.
  • An oblique-finned control cylinder 5 controls the passage of the web from the cylinder 3 to the cylinder 4.
  • the doffer cylinder 4 delivers the upper randomized web between two conveyor belts 14, 15 having the same characteristics as the conveyor 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 randomiser cylinder 3 in cooperation with the intermediate combing cylinder 2b.
  • the doffer cylinder 4 associated with the intermediate combing cylinder 2b therefore delivers two webs arranged one on top of the other between the conveyor belts 8 and 9, the webs being deposited by the belts on the lower randomized web conveyed by the final conveyor belt 6.
  • the assembly constituted by the upper combing cylinder 2b and the elements 3, 4, 5, 10, 15 associated therewith is advantageously carried by a support structure which can be moved between the active position shown in Figure 3 and a rest position in which only the combing cylinder 2a and 2b are operational.
