  SET OF FINISHED PRODUCTS STACKED ON A PALLET

  AND METHOD FOR PRODUCING SUCH AN ASSEMBLY

  The present invention relates to a set of finished products stacked on a pallet and the method of manufacturing a set

of finished products.

  It is known to package finished products in packaging formed by a film of plastic material welded according to a generator of the product, this welding comprising a breaking wire.

  allowing to open the packaging to consume the product.

  However, this type of packaging and opening is reserved for unitary products whose film constituting the envelope

  has characteristics of low mechanical resistance.

  It is also known to produce sets of finished products stacked on a pallet, so as to constitute easily transportable and manipulable batches. These batches of products must therefore be wrapped with a film having

  important mechanical resistance characteristics.

  The prior art provided for wrapping these pallets in a sheet of suitable size making it possible to make the turn of the palletized assembly, and to join the edges of the sheet by heat sealing. However, this type of packaging leads to handling difficulties during unpacking when it comes to cutting the envelope. Indeed, very often, users damage the packaged products by cutting the film. This is particularly true when acts of products of low mechanical resistance, such as articles of hygiene or for domestic use containing cellulose, in particular the products in cellulose wadding: toilet paper, paper towel, etc. A first object of the invention is therefore to propose a set of finished products which allows easy storage and transport while facilitating the unpacking and unit consumption of these products. This object is achieved by the fact that the assembly, consisting of finished products and their pallet on which they are stacked, wrapped to form a delivery and transport unit is characterized in that a cutting wire is attached to an element on the one hand, and on the other hand, removably, at a point on the assembly remote from said element,

  the whole being a banner on a helix with a stretch film.

  According to a particular embodiment, said element consists of the pallet. According to another feature of the invention, the yarn

  cutout is stapled to the pallet.

  According to another method of fixing the wire, the cutting wire is fixed by means of a loop around a stud of the

palette.

  Another object of the invention is to allow an opening

easy packaging.

  This object is achieved by the fact that the end of the wire detachably fixed at a point distant from the element comprises a

loop.

  According to another feature of the invention, the loop is of sufficient size to allow gripping and is provided,

  on at least half of it, a cladding.

  According to another embodiment, the loop is of dimension

  allowing the passage of a fixing ring.

  According to another feature of the invention, the wire is

triangular section.

  According to another feature of the invention, the wire is twisted. According to another feature of the invention, the wire is made of steel. According to another feature of the invention, the wire is made of nylon. According to another feature of the invention, two stages of packaged products are separated from the following two stages by a plane

cardboard-based.

  According to another feature of the invention, the wire is made of polyethylene. Another object of the invention is to propose a method of

  manufacturing of easily automated finished products.

  This object is achieved by the fact that the manufacturing process consists of: placing several layers of products superimposed, one on top of the other, on a pallet; making integral with an element of the assembly, one end of a resistant wire; maintaining the other end of the wire on the stack to bandage a stretch film around the assembly according to a helix;

  to secure the film on itself at the top of the packaging.

  According to a feature of the invention, the helical wrapping is multilayer and is produced by a film reel

rotating around the fixed pallet.

  Other features and advantages of the present invention

  will appear more clearly on reading the description

  below made with reference to the accompanying drawings in which: Figure 1 shows an elevational and perspective view of the set of finished products according to the invention; FIG. 2 represents an alternative embodiment of the set of finished products according to the invention; FIG. 3 represents a first embodiment of the end of the cutting wire according to the invention; FIG. 4 represents a second embodiment of the end of the cutting wire according to the invention; FIG. 5 represents a method of fixing the end of the cutting wire according to the invention; Figure 6 shows the method of fixing the assembly

according to the invention.

  The set of finished products is made up of sales units (10) consisting, for example, of toilet paper rolls assembled in packs of 9 elements, or, of paper towels rolled together in packs of 3, or well, periodic towels, tampons, baby diapers and other products that can be damaged when cutting the wrapping Each sales unit (10) is arranged on a pallet (1), on which a cardboard plate has been placed ( 8), so as to constitute a first layer (2) of sales units (10) A second layer (3) of sales units (10) is arranged on the first layer (2) and so on until counting the number of layers necessary to constitute, with the pallet, the set of finished products corresponding to a transport unit having the desired dimensions When the last layer of products formed by sales units is placed, it is covered a cap (7), and, we just fix at one place in this assembly, preferably on the sides of the pallet (1), the end of a wire (6), the other end of which, provided with a loop (60), is made integral with the assembly removably at a location remote from the first, such as the upper cap (7) It is also part of the invention to reverse the fixed and removable points, that is to say to choose a point of fixing on the cover and letting the wire hang After having arranged the sales units in layers so as to constitute the load of the pallet, the latter is transported to a wrapping unit in which a reel of resistant plastic film, for example of octene-based low density polyethylene having a thickness of the order of 17 microns, a surface mass of 15.1 g / m 2 and a tensile strength in the direction of the strip of 35.1 N / mm 2 and in the transverse direction of 27 N / mm 2, is used to perform a helical wrapping ïdal multilayer around the set of finished products This reel therefore moves around the pallet in a rotational movement as well as in an upward movement When the assembly has been wrapped, a final film round is made in the upper part, made integral with the lower layer of film, either by gluing or by heat sealing. The assembly thus produced constitutes a transport package which is particularly advantageous for the units for selling toilet paper or paper towels, which correctly ensures their protection while allowing easy opening of the packaging by tearing of the wrapping film, thanks to the cutting wire (6) To facilitate this cutting, the wire will preferably be of triangular or twisted section, and made of smooth or twisted steel , having a diameter of 0.12 to

  0.2 mm, or 0.2 mm diameter nylon.

  The cutting wire can be made of any other material, provided that it has good tensile strength and a cutting effect, making sure to choose a small diameter and

  possibly working on the shape of the wire.

  The function of the wire is to cut the portions of strips passing over it and, since this strip is not weakened by a weld line or any other pre-cut line whose position is difficult to define, the wire must

  have features that facilitate cutting.

  Advantageously, as shown in FIG. 3 or in FIG. 4, the wire (6) may have, at its free end, a loop (60) formed by a crimping (61) of the end of the wire on itself This loop (60) can be covered with a sheath (62) formed in a suitable material on at least half of the periphery of the loop, so as to constitute a handle of

gripping.

  A second variant of embodiment may consist in producing a loop (60, fig 4) of smaller dimension which does not allow gripping using a hand, but of a sufficient size to allow the passage of a metal ring (63) whose dimensions allow gripping by

a hand or a finger.

  The other end of the wire can be fixed to the pallet (1), either by stapling to the pallet, or, as shown in the figure, by a loop (65) formed around a stud (11) by the wire ( 6)

passing through an eyelet (64).

  A second embodiment of the set of finished products can be constituted, as shown in FIG. 2, by a stack of two stages (2, 3) of sales units (10) above which a separation is placed. (9) in cardboard to then again have on this separation (9) two new floors of sales units and above these two new floors another separation in cardboard, and so on, until the dimensions are obtained desired for the pallet The last two floors of sales units are covered by a cover (7), as for the first

variant.

  The assembly (12) of products stacked before wrapping is conveyed on a carpet to the wrapping unit, which is constituted by a device allowing a reel (50) of ribbon (5), formed of a film of polyethylene, to move in rotation around the stack (12) according to the movement referenced (53), the reel rotating on its axis of symmetry according to the movement (51) and moving in an upward or downward movement referenced by the arrow (52) All of these three combined movements -ô allows helical wrapping to be carried out, possibly on several superimposed layers. At the top of the stack, the ribbon makes an additional turn without continuing its longitudinal progression, so as to come superimpose the film on a part of the ribbons located on the lower layer, and allow the assembly to be joined together, either by gluing or by heat sealing. Other modifications within the reach of those skilled in the art make

  also part of the spirit of the invention.
