Definitions

  • the present invention relates to an apparatus for compacting a continuous textile substrate by means of an elastic belt.
  • the compacting process of fabrics or textile substrates is one of the main processes in the field of textile finishing and has the purpose of giving stability to the fabrics before going to the manufacturing step.
  • the stability and compaction of the fabric is imparted with machinery with consolidated technology which use a change in the curvature of a felt or rubber belt on which the fabric on which to impart the compaction is placed.
  • the change of curvature of the support then imparts a longitudinal retraction to the fabric which is then pressed against a hot cylinder, which stabilizes the compacting effect ensuring the dimensional stability of the fabric once it leaves the machine.
  • the compacting (or shrinking) treatment of fabrics is carried out essentially by means of a so-called "compression” technique which is based on the use of a substantially deformable belt, to which the fabric to be compacted is tightly coupled.
  • the deformation of the belt in the longitudinal direction of advancement by means of mechanical means suitable for the purpose, substantially consists of the succession of a first expansion step and a second contraction step.
  • the fabric, engaged integrally with the deformable surface of the belt undergoes, in particular during the contraction step, a "compression" in the direction of advancement, that is, a compaction of its structure and, ultimately, a longitudinal shrinking.
  • the deformability of the belt may be determined by the type and features of the material of which it is made and also by the type of mechanical stress exerted thereon by the mechanical means adapted to deform it.
  • deformations by pressing of the belt are known which cause the expansion (elongation) thereof followed by a contraction (shortening) to the initial relaxed state; or deformations by variation of peripheral speed of the belt obtained by sliding it on rollers or cylinders with different radius of curvature with an alternately convex and concave path which alternately cause an increase (lengthening) and a decrease (shortening) of peripheral speed; or, finally, deformations by longitudinal traction of the belt (elongation) followed by a release of the traction (shortening) to the initial relaxed state.
  • GB patent 563 638 describes an apparatus for compacting fabrics which aims to improve the prior art by using an endless elastic belt supported and guided by rollers, one of which rotates at a variable speed and higher than the roller that precedes it. In this way, the portion of the belt comprised between said two rollers is placed in an elongated state, while in the following section, as tension is relaxed, the belt undergoes a longitudinal contraction equal to the previous elongation.
  • the fabric coupled to the belt at the elongated portion thereof, follows it in the subsequent relaxed portion, partially winding around a rotating and heated cylinder, also undergoing a corresponding longitudinal contraction or shrinkage.
  • a further negative aspect is linked to the fact that the elastic belt, which is therefore extendable in length, subjected to longitudinal traction also deforms transversely with a consequent and uncontrollable decrease in width.
  • both dimensions of the belt tend to regain the original size, that is to say, it re-widens and since, as mentioned, it has not maintained any minimum residual tension, its surface tends to flow loosely and not outstretched, transmitting such irregularities to the fabric coupled thereto.
  • this solution provides for a pre-tensioning traction to be applied to the elastic belt in such a way that it maintains a minimum residual tension at the end of the release step of the traction which caused the elongation thereof.
  • the tissue compaction apparatus described in EP1657340A1 comprises a heated rotating cylinder around which an elastic belt is partially wound.
  • the elastic belt is moved by a plurality of motorized rollers and idle return rollers according to a predefined closed path.
  • the roller apparatus is configured in such a way that by operating on the relative position of one of the rollers it is possible - during assembly of the belt on the rollers - to pre-tension the belt itself with respect to its relaxed state.
  • the elastic belt is further stretched by elongation before coming into contact with the cylinder.
  • the belt comes into contact with the fabric in the winding section around the cylinder, the belt is free to contract longitudinally, thereby dragging the fabric with it in a relative movement with respect to the cylinder. In this way, the fabric is dragged by the longitudinal contraction movement of the elastic belt and is thus compacted longitudinally.
  • the tensioning of the elastic belt is achieved by the combined action of two triads of rollers which are arranged in diametrically opposite positions with respect to the rotating cylinder.
  • a first triad of rollers is positioned immediately upstream of the heated cylinder (upstream of the first contact point of the belt with the cylinder), while a second triad of rollers is positioned downstream of the cylinder (downstream of the point of detachment of the belt from the cylinder).
  • an idle return roller is an idle return roller.
  • the rollers of the first triad are all motorized and rotate at the same first tangential speed, with alternating directions of rotation.
  • the first rollers that the belt encounters are motorized and rotate at the same second tangential speed, with alternating directions of rotation.
  • the third roller of the second triad is instead idle.
  • the elastic belt is elastically stretched by the entire path section opposite to that of winding around the cylinder, differentiating the tangential speeds that the two triads of rollers impose on the elastic belt.
  • the first tangential speed i.e. imposed by the first triad of rollers
  • the second tangential speed i.e. imposed by the second triad of rollers
  • the compaction apparatus described above allows the compaction process to be improved by virtue of the belt pre-tensioning, but the results obtained are however not completely satisfactory.
  • the compaction apparatus described above still does not allow precise control of the elongation of the elastic belt and therefore of the degree of tension imposed on the belt itself.
  • the roller handling apparatus does not allow completely eliminating slippage of the elastic belt with respect to the guide rollers. This adversely affects the efficiency of the compaction process.
  • the object of the present invention is to eliminate in whole or in part the drawbacks of the prior art cited above, by providing an apparatus for compacting fabrics by means of elastic belt which allows the tension of the elastic belt to be controlled more precisely so as to make the fabric compaction process more efficient.
  • a further object of the present invention is to provide an apparatus for compacting fabrics by means of elastic belt which allows the stresses imposed on the elastic belt to be reduced.
  • a further object of the present invention is to provide an apparatus for compacting fabrics by means of elastic belt which is simple and cost-effective to manufacture.
  • a further object of the present invention is to provide an apparatus for compacting fabrics by means of elastic belt which may be managed in an operationally simple manner.
  • reference numeral 1 indicates as a whole an apparatus for compacting a continuous textile substrate by means of an elastic belt according to the invention.
  • the textile substrate T may be of any type; in particular it may be an orthogonal (shuttle) fabric or a knitted fabric.
  • the textile substrate may be formed by any type of fiber used for shuttle and knitted fabrics.
  • the compacting apparatus 1 comprises:
  • such a roller system comprises a plurality of idle return rollers 33, 34, 35 and a plurality of motorized rollers 31, 32.
  • the motorized rollers 31, 32 may be operated so as to slide the belt 20 along the aforementioned closed path, imposing an additional tensional state of elongation on the belt with respect to the pretensioning one at a first section T1 of said path which extends - with respect to a direction of advancement X of the belt - upstream of a second section T2 of such a path in which said belt 20 is kept in contact with the rotating cylinder.
  • the compacting apparatus 1 further comprises means 40 for guiding a textile substrate T between the belt 20 and the heatable cylinder 10 along the second section T2 of such a closed path.
  • the compacting action on the textile substrate T takes place along the aforementioned second section T2 of the closed path.
  • the elastic belt contracts elastically, passing from the additional tensional state of elongation, which was imposed thereon upstream in the first section T1, to a state close to that of pretensioning.
  • the aforementioned roller system comprises:
  • the motorized drive roller 31 is the roller placed immediately upstream of the heatable cylinder 10
  • the second idle return roller 34 is the roller placed immediately downstream of the heatable cylinder 10.
  • the first section T1 of the aforementioned closed path (at which the belt 20 is in use elastically elongated, receiving an additional tensional state of elongation with respect to the pretensioning one) extends between the motorized brake roller 32 and the motorized drive roller 31, passing in partial winding around the first idle return roller 33.
  • the second section T2 of path (at which the belt 20 in use contracts itself, losing the additional tensional state of elongation to return to the pretensioning state) extends between the motorized drive roller 31 and the second idle return roller 34.
  • the above closed path is completed by a third section T3 of path extending between the second idle return roller 34 and the motorized brake roller 32.
  • the belt 20 is in a relaxed tension state with respect to the first section T1 of path, substantially corresponding to the pretensioning state.
  • the "closed path” corresponds to the total extension of the belt 20 when mounted in pretension on the roller system.
  • the closed path is not affected by local contractions and local elongations of the belt.
  • a section of path - distinct from that of contraction in contact with the cylinder - is introduced into the closed path, in which the belt is free to progressively return to the pretensioning state, without being subject to an additional elongation state.
  • the belt is therefore continuously stressed in elongation or contraction, without actually being able to remain in the pretensioning state, that is in the state of minimum elongation, which may be considered the rest state.
  • the belt already immediately downstream of the brake roller, the belt begins to undergo the elongation action exerted by the drive roller.
  • the aforementioned third section T3 has been introduced in the closed path, in which the belt - after having contracted in the second section T2 - is free to remain in the pretensioning state.
  • the third section T3 may be considered a rest section for the belt, as opposed to the first elongation section T1 and the second contraction section T2.
  • the motorized drive 31 and brake 32 rollers, the idle return rollers 33, 34, 35, as well as the heatable cylinder 10 are made of metal, preferably steel.
  • the motorized brake roller 32 and the motorized drive roller 31 are both provided with a rubber coating 36 which covers the respective cylindrical side surfaces intended to contact the belt 20.
  • the friction coefficient between the motorized rollers and the belt is increased with respect to the case of contact of the belt on the bare surface of the cylinder, typically smooth metal.
  • the increase in the friction coefficient reduces the risk of slipping between the belt and the rollers. This contributes to improving the control over the elongation action of the belt and therefore to increasing the efficiency of the compaction process of the textile substrate.
  • both the first idle return roller 33 and the second idle return roller 34 are not rubber-coated.
  • both the first idle return roller 33 and the second idle return roller 34 are provided with a cylindrical side surface, preferably made of metal material, intended to come into direct contact with the belt 20 without the interposition of a rubber coating covering such a cylindrical side surface.
  • the idle return rollers 33 and 34 are not rubber-coated and the elastic belt 20 comes into direct contact with their metal side surface, the friction between the belt and the idle rollers is reduced. In this way, by virtue of the reduction of friction, the belt encounters fewer obstacles in its elastic extension and subsequent contraction.
  • the additional tensional state of elongation is imposed on the belt 20 by acting on the speeds of the motorized drive roller 31 and the motorized brake roller 32, so as to create a difference between the tangential speeds of the side surfaces of the two rollers (intended to contact the belt).
  • the tensional state of elongation (measurable for example by percentage of elongation with respect to the pretensioning state) increases as the difference in these speeds increases.
  • the apparatus 1 may comprise a control unit 50, preferably electronic, configured to control the rotation of the motorized drive roller 31 and of the motorized brake roller 32 so that said two motorized rollers 31, 32 rotate in the same direction and so that the tangential speed Vt of the motorized drive roller 31 is higher than the tangential speed Vf of the motorized brake roller 32 according to a predefined ratio Vf/Vt.
  • a control unit 50 preferably electronic, configured to control the rotation of the motorized drive roller 31 and of the motorized brake roller 32 so that said two motorized rollers 31, 32 rotate in the same direction and so that the tangential speed Vt of the motorized drive roller 31 is higher than the tangential speed Vf of the motorized brake roller 32 according to a predefined ratio Vf/Vt.
  • such a predefined ratio Vf/Vt between the tangential speed of the motorized brake roller 32 and the tangential speed of the motorized drive roller 31 is adjustable as a function of the extent of additional longitudinal elongation to be imposed on the belt at the first section of path T1.
  • said predefined ratio Vf/Vt is between 0.5 and 0.9, and preferably equal to 0.7.
  • the heatable rotating cylinder 10 is motorized.
  • heatable cylinder it is meant in particular a cylinder provided with or associated to heating means.
  • the heating means can be of any type suitable for the purpose, i.e. heating the surface of the rotating cylinder.

  • the motorized drive roller 31, the motorized brake roller 32 and the first idle return roller 33 are positioned in relation to each other so as to assume a compact configuration.
  • compact configuration it is meant a configuration in which said three rollers 31, 32, and 33 are in close proximity to each other when compared with the other rollers 34 and 35 of the roller system.
  • the "compact configuration" is essentially aimed at reducing as much as possible the extension of the first section T1 of the path in favor of the third section T3 of the path.
  • said three rollers 31, 32, and 33 may be arranged to form a triad of rollers with aligned centers of rotations. This choice is preferred from a constructive point of view as it allows a reduction in the overall dimensions and simplifies the support structure of the rollers themselves.
  • configurations of the triad of rollers may be provided in which the rollers are not aligned with each other.
  • the motorized drive roller 31, the motorized brake roller 32 and the first idle return roller 33 are positioned in relation to each other such that the winding angle of said belt 20 around the motorized drive roller 31 and the motorized brake roller 32 is not lower than 90°.
  • the belt is installed on the triad of rollers so as to follow an S-path between the three rollers.
  • the two motorized rollers 31 and 32 contact the belt on its inner surface, while the first idle return roller 33 contacts the belt on its outer surface.
  • the first idle return roller 33 interposed between the two motorized rollers 31 and 32, may thus push the belt against them, favoring the winding of the belt.
  • the "push" action of the return roller and therefore the effect in terms of winding may be calibrated by operating on the nominal diameters of the rollers and/or on the relative position of the centers of rotation.
  • the motorized drive roller 31 is the roller placed immediately upstream of the heatable cylinder 10
  • the second idle return roller 34 is the roller placed immediately downstream of the heatable cylinder 10.
