Definitions

  • the invention relates to a strip with longitudinal reinforcement, its production and its use.
  • Document FR-A-2273745 discloses the production of a fold adjacent to the longitudinal edge, this edge being "floating". The folding is carried out by rollers. The intended application is not reinforcement but a sort of spacer preventing successive coiled layers from being in reciprocal contact.

  • a strip such as the one concerned comprises at least one longitudinal reinforcement zone constituted, at least in part, by at least four longitudinal zones of folding of the strip, adjacent to each other, overlapping at least substantially flat, at at least partially, one on top of the other, in the same longitudinal region of the strip, N being a positive integer at least equal to two.
  • a package for a load comprises at least one such section of strip in the longitudinal direction. More specifically, this section of strip is applied to the packaged load, so that a longitudinal reinforcement zone of the strip section is located where the packaging is to be reinforced or the load more protected or any other desired location.
  • a method of packaging such a load comprises the various stages in which a flexible strip with longitudinal reinforcement is unwound, a relative displacement of the strip is carried out with respect to the load to be packaged so that the strip is applied to the load and the strip is rigidly associated on itself and / or on the load. More specifically, either we start from a strip, devoid of reinforcement and we unwind it to successively carry out, first, continuously, the longitudinal reinforcement then apply the strip thus reinforced to the load; either we start from a strip with longitudinal reinforcement wound in a reel, we unwind it and we apply it to the load.
  • One possible method for continuously producing such a reinforcement on a strip is such that one starts from a single-thickness strip, continuous as a whole, devoid of reinforcement, the strip is scrolled in a longitudinal direction in a relative movement and in at least one longitudinal folding phase, at least two adjacent longitudinal folding zones of the strip to be overlapped flat over one another are progressively brought in longitudinal and transverse directions to form at least one fold longitudinal constituting at least part of the longitudinal reinforcing zone.
  • a first embodiment in which one starts from a continuous strip without reinforcement is characterized in that in the first place, a first longitudinal zone of the strip is scrolled in relative fashion, longitudinally the long and against a first longitudinally extended and limited pad located on a first surface of the strip and, on the other hand, a second longitudinal zone of the strip, longitudinally along and against a second longitudinally extended and limited pad located on the second surface of the strip; and secondly, the first and second pads are placed so that their upstream end portions are separated transversely from one another, that they approach one another from their upstream end portions to their end portions downstream, and that their downstream end portions are at least partially superimposed and spaced from one another in the direction perpendicular to their plane and placed on either side of at least part of one of the longitudinal zones folding.
  • a second embodiment is characterized in that one starts from a sheath with continuous longitudinal bellows as a whole and is made to scroll in a longitudinal direction and in at least one longitudinal opening phase, the sheath is split longitudinally and the sheath in transverse direction, that is to say perpendicular to its longitudinal axis and in its own plane while keeping the bellows, at least partially, so that the open sheath forms a flat strip whose longitudinal bellows constitutes the longitudinal reinforcement .
  • a device for implementing this method comprises means for continuously feeding a strip without reinforcement, for driving this strip in longitudinal movement and for evacuating the strip with reinforcement; means for keeping the strip tensioned in the longitudinal direction; at least first and second longitudinally extended but limited pads which, in their active state, have their downstream end portions at least partially superimposed and spaced from one another in the direction perpendicular to their plane, having the function of conforming the band which slides over them so that these superimposed downstream parts and spaced apart cover the longitudinal folding zones of the strip.
  • a particular case of the packaging process for the packaging application of a paper reel is such that, on the one hand, the load has a generally cylindrical shape, for example, circular, in particular with its axis of revolution placed horizontally, this filler being in particular a reel of paper, and, on the other hand, the film is of the stretchable type; in at least one optional first phase, the strip is unwound without the need for reinforcement thereon and this strip is applied to at least part of the cylindrical surface of the load and, in at least a second phase, it is unwound the strip and a longitudinal reinforcement is produced on it and this strip is applied with reinforcement with its reinforcement to an end edge of the cylindrical surface; at least during the second phase or phases, the film is stretched or pre-stretched, which has the effect of causing the application of this film on the end face or faces of the load; the film strip is cut transversely and its end end part is secured to the load and / or to the intermediate part of the film strip already applied to the load.
  • An installation for implementing this method comprises means for supporting a reel of film strip with a horizontal axis of the motorized support means for the load, capable of allowing it to pivot about its axis of revolution; a device for continuously producing a longitudinal reinforcement zone on the film strip, interposed between the reel support means, respectively the film strip reel itself, and the load support means, respectively the load itself, the film strip passing through this device; means for cross-cutting the film strip; means for securing the film strip to itself and / or to the load; means for ensuring horizontal relative sliding of the device and load support means parallel to the axis of the load; and means for stretching or pre-stretching the film.
  • the packaging process for the wrapping application is such that, on the one hand, the load has a generally parallelepiped shape in particular with its axis placed vertically, this load being in particular a palletized load and, on the other hand, the film is of the stretchable type; in at least one phase, the strip is unwound, a longitudinal reinforcement is produced thereon and this strip is applied with reinforcement to the load and, simultaneously, the film is stretched or pre-stretched.
  • a machine for implementing this method comprises means for supporting a reel of film strip with a vertical axis; load support means; means for effecting relative displacement of the film strip reel support means, respectively of the film strip reel and load support means, respectively of the load, pivotally about a vertical axis; a device for carrying out, continuously, a reinforcement on the film strip, interposed between the support means of the film strip reel, respectively the film strip reel, and the load support means, respectively the charge itself , the strip of film passing in advance through this device; means for cross-cutting the film strip; means for securing the film strip to itself and / or to the load; and means for stretching or pre-stretching the film.
  • the invention is based on the concept of a film strip in which is integrated a homogeneous longitudinal reinforcement comprising one or more longitudinal folds, that is to say one or more superimposed layers or thicknesses of film.
  • a homogeneous longitudinal reinforcement comprising one or more longitudinal folds, that is to say one or more superimposed layers or thicknesses of film.
  • Such a strip can be produced continuously from a conventional strip of the prior art.
  • the location of the reinforcement in the longitudinal direction or in the transverse direction, its transverse extent, its importance (number of superimposed layers), allow numerous variants of embodiment as required.
  • This reinforcement makes it possible to imprison a solid, liquid or gaseous body.
  • the strip and its longitudinal reinforcement form a single unit, inseparable, which distinguishes the strip according to the invention from two layers of strip simply superimposed.
  • the invention firstly relates to a flexible strip 1, more specifically but not exclusively applicable to the constitution of packaging, more especially constituted by a plastic film, of the type which has come from one-piece production.
  • This strip 1 comprises at least one longitudinal reinforcement zone 2 constituted, at least in part, by N longitudinal folding zones 3a, 3b ... 3N of the strip 1, adjacent to each other, overlapping at least substantially flat , at least partly on top of each other, in the same longitudinal region of the strip 1, N being a positive integer at least equal to two (FIG. 2).
  • Such a strip 1 according to the invention can be compared to a strip of the known state of the art according to Figure 1.
  • the strip according to the known state of the art came from a workpiece and has a single thickness over its entire surface, the physical properties of the strip being homogeneous or more or less homogeneous over its entire surface, both longitudinally and transversely. These properties are in particular the thickness, the power of shock absorption, etc.
  • the strip 1 according to the invention comprises a longitudinal reinforcement zone integrated into the strip 1 and produced by the strip 1 itself , due to its longitudinal folding.
  • the strip 1 according to the invention therefore opposes, in this respect, other strips also known from the state of the art in which a reinforcement is attached to the strip.
  • the strip 1 is bounded by two longitudinal edges 4 parallel to the longitudinal axis 5 of the strip 1.
  • transverse direction means a direction perpendicular to the longitudinal axis 5 and in the plane of the strip 1.
  • Strip 1 defines a sheet having two large opposite surfaces respectively 6A and 6B (for example the place and the reverse or the front and back).
  • two (or more) longitudinal folding zones 3A, 3B, which are adjacent to each other at least substantially flat is meant the realization with the strip 1 of a longitudinal fold 7, parallel to the longitudinal axis 5 separating the two zones 3A, 3B also longitudinal in contact by their same surface 6A or 6B or having their same surfaces 6A or 6B facing one another.
  • the longitudinal reinforcement zone comprises two longitudinal folding zones 3A and 3B and a single fold 7 (FIG. 4A).
  • the longitudinal reinforcement zone has three longitudinal folding zones 3A, 3B, 3C superposed and two folds 7A, 7B, spaced transversely from one another (FIG. 3 ).
  • Reinforcement zone 2 is understood to mean the fact that in this zone of strip 1, strip 1 has a greater number of film thicknesses than in the rest of strip 1. It is understood by flat covering that longitudinal folding zones 3A, 3B are applied one on the other or turned towards each other so that the strip 1 retains, despite the presence of the longitudinal reinforcement area, a general shape of flat strip, simply thicker at the location of the reinforcement thus formed.
  • a longitudinal reinforcement zone 2 can be used functionally in many possible ways, either for its strength qualities, or in that it constitutes an additional thickness compared to the rest of the strip 1 having a shock protection function. These and other functions are used to advantage in the various possible applications of such a strip 1 according to the invention.
  • the strip 1 with reinforcement 2 can be the subject of numerous variant embodiments: a longitudinal reinforcement zone 2 is either adjoining or close to the longitudinal edge 4 of the strip 1, or in or near the median longitudinal part of the strip 1, is situated in a lateral part of the strip 1, between its longitudinal axis 5 and a longitudinal edge 4 (respectively FIGS. 4A, 4B, 4C).
  • the strip 1 can comprise either a single longitudinal reinforcement zone 2, or several longitudinal reinforcement zones 2 (respectively FIG. 4B in particular and FIG. 4D or 4E). In the case where there are several longitudinal reinforcement zones 2, these are either adjacent or separated transversely from one another (FIGS. 4E and 4D respectively).
  • the strip 1 is characterized by a symmetrical or substantially symmetrical arrangement of the longitudinal reinforcement zone (s) 2 relative to the median longitudinal axis 5 of the strip 1 (FIGS. 4B, 4D to 4K), by opposition to an asymmetrical arrangement ( Figures 4A, 4C).
  • the strip 1 is characterized by an arrangement of a reinforcement zone 2 which in the longitudinal direction is either continuous or discontinuous, arranged in separate longitudinal sections in particular separated from each other, more or less extended in the longitudinal direction ( Figures 5A and 5B respectively).
  • the strip 1 is characterized by an arrangement of a longitudinal reinforcement zone 2 either elongated or substantially elongated or curvilinear, or extended transversely (respectively FIG. 4F and FIGS. 4, 4A, 4B, 4C).
  • a longitudinal reinforcement zone 2 either elongated or substantially elongated or curvilinear, or extended transversely (respectively FIG. 4F and FIGS. 4, 4A, 4B, 4C).
  • the strip 1 is characterized by an arrangement of a longitudinal reinforcing zone 2 on the strip 1 which is either localized or extended transversely over all or only over part of the transverse width of the strip 1 (respectively Figures 4B and 4G for example).
  • the reinforcement zone 2 occupies only a small part of the strip 1 in the transverse direction.
  • the reinforcement zone 2 can occupy a significant part of the width of the strip 1 or all of this width.
  • the N longitudinal folding zones 3A, 3B, ... 3N constituting the longitudinal reinforcement zone 2 are either of the same transverse width and superimposed while then constituting a longitudinal reinforcement 2 of constant thickness in transverse direction, or offset and / or of different widths, thus constituting a longitudinal reinforcement 2 of variable thickness in the transverse direction (respectively FIGS. 4H and 4I).
  • a reinforcement 2 has a greater thickness in its median longitudinal line and a smaller thickness on its longitudinal edge with, in particular, a thickness decreasing from the median longitudinal line to the longitudinal edge.
  • This structural characteristic of the strip 1 is important and advantageous since it allows the production of a more or less significant longitudinal reinforcement zone 2 depending on the location in the transverse direction.
  • the longitudinal folding zones 3A, 3B ... are joined together in particular by welding 8 (FIG. 4J), this welding 8 being in the form of points or zones, or lines, and continuous or discontinuous.
  • This embodiment is well suited to the case where the strip 1 is intended to be stored in an intermediate manner (that is to say between its manufacture and its use), in particular wound in a reel. She then prevents the longitudinal reinforcement zone 2 from disassembling.
  • the longitudinal reinforcement zone 2 is produced immediately before the implementation of the strip 1 thus reinforced - as described below - it is possible to dispense with such fastening 8, the application of the strip 1 on the load to be packaged (in the case of a packaging by application application) being sufficient to prevent the longitudinal reinforcement zone 2 from coming apart. This is an important feature of the invention.
  • a body 9 is incorporated into a longitudinal reinforcement zone 2 by being inserted between two adjacent longitudinal folding zones 3A, 3B ( Figures 4K).
  • This body 9 is for example a gas, in particular air, or a wire or strip for cutting the strip 1 or other function, or a liquid or a paste, or an informative or advertising medium, or an element of stiffening or additional reinforcement, or a shock absorbing element such as plastic foam.
  • this embodiment with body 9 inserted is combined with the previous one, with welding - in particular joining -, so as to ensure effective positive confinement of the body 9 in the longitudinal reinforcement zone 2. This is generally essential in the case where the body 9 is a gas, a liquid, a paste.
  • one or more longitudinal lines of weakness for the longitudinal rupture of the strip 1 may be provided at the location of a longitudinal reinforcement zone 2 or possibly outside such a zone.
  • the plastic film constituting the strip 1 is either heat shrinkable, or cold stretchable, especially in the longitudinal direction.
  • the film constituting the strip 1 is either continuous (without notable perforations) or discontinuous, in particular in the form of a net, or with macro-perforations.
  • the strip 1 according to the invention may also have the other characteristics generally known for the conventional strips of the prior art, in particular the existence of transverse breaking lines or transverse reinforcements, in particular by transverse folding.
  • strip 1 covers, as a general case and in the simplest embodiment, a strip originally of single thickness as has been generally described, but also, more generally, any sheet of film arranged with in a manner other than a strip, as well as a strip formed by a complex of several films or even a flat sheath, which corresponds to two superposed strips joined to one another.
  • a flat sheath can be of the type with longitudinal bellows.
  • these bellows can themselves constitute, being arranged flat, the longitudinal reinforcement zones 2 according to the invention.
  • This form of sheath, in particular with bellows is that of the strip 1 either finally, that is to say ready for use, or originally, with a view to the subsequent production of the longitudinal reinforcement zone 2.
  • the "longitudinal" character includes not only the abovementioned meaning, but also more generally means a direction along which the film extends over a very great length relative to its width, in particular can scroll with unwinding.
  • the invention then relates to a package for a load 10 comprising at least one longitudinal section of a strip with longitudinal reinforcement zone 2 as just described.
  • the strip section 1 is applied to the packaged load 10, a longitudinal reinforcement zone 2 of the strip section 1 being located where the packaging is to be reinforced, or the load 10 more protected.
  • the reinforcement can be located at other desired locations, as required and the function fulfilled by the reinforcement zone 2, possibly the body 9 inserted.
  • a longitudinal reinforcement zone 2 is applied to a projecting zone of the load 10, in particular an angle, a corner, an edge (FIG. 6).
  • the strip section 1 can also be part of the packaging without being applied to the load.
  • the strip section 1 can be located at the place where the packaging is to be opened, and this is particularly the case where the film strip 1 has an opening wire 9 and / or break lines.
  • the application of the strip section 1 on the load 10 and in particular on a protruding area allows the longitudinal reinforcing area 2 to be maintained without the need for additional attachment.
  • the invention also relates to a packaging method for producing such packaging.
  • a packaging method for producing such packaging comprises different stages in which a flexible strip 1 is unwound with a longitudinal reinforcement zone 2, a relative displacement of the strip 1 is carried out relative to the load 10 to be packaged in particular in order to apply the strip 1 to the load 10 and the strip 1 is rigidly associated on itself and / or on the load 10 (FIG. 7).
  • a strip (simple thickness, this also comprising the case of a flat sheath, as we have already seen) without reinforcement and it is unwound (more generally it is the object of a feeding) to successively firstly realize in particular continuously (or the) zone (s) of longitudinal reinforcement 2, then apply the strip thus reinforced on the load 10 (upper left part FIG. 7).
  • a second variant one starts from a strip with longitudinal reinforcement 1 already produced and in particular wound in a reel, it is taken up, in particular it is unwound, and it is applied to the load 10 as before (upper right part of FIG. 7) . Consequently, the step of producing the longitudinal reinforcement zone 2 is either integrated into the packaging process, or separate, the packaging process then using a reinforced strip 1 prepared separately and presented, for example, on a reel. .
  • a cold-stretchable plastic film is used and the strip 1 is stretched longitudinally during its application to the load 10, in particular either conventionally by the load 10 itself (conventional stretching), or by pre-stretching (the stretching is then dissociated from the load and carried out just before application) (part lower left figure 7).
  • a film of heat-shrinkable plastic is used and the strip 1 is heated once applied to the load 10, (lower right part in FIG. 7).
  • this step of the packaging process has the effect of ensuring the tight application of the strip 1 on the load 10 and, moreover, the rigid association of the longitudinal reinforcement zone 2 with the rest of band 1.

  • Such packaging has the characteristic that the reinforcement is longitudinal, integrated into the strip 1 itself, that it can be placed in any desired location of the load 10, including for example on an edge or a corner thanks to the presence of the strip part 1 devoid of reinforcement zone 2 placed on either side of this zone 2 and forming a support.
