Definitions
- the invention relates to a mandrel for supporting a reel of paper, especially toilet paper.
- a reel of paper especially toilet paper.
- Said rollers are formed by winding the paper around a mandrel generally made of cardboard.
- the choice of the board results from the compromise sought by the manufacturers between the adaptation of the material to the mechanical constraints of manufacture and the desire to limit the cost of the product in the end. It turns out that these mandrels are subjected during the manufacture of the rollers to various mechanical stresses whether during the passage in the winder, when packing the rolls in the packages or when stacking the roll packets on the pallets intended for their transport.
- the constituent material of these mandrels must in particular have good rigidity characteristics to withstand the loads and forces to which the rollers are subjected throughout their production and distribution cycle.
- a material that does not have sufficient strength would indeed cause a deformation of the individual rolls or a collapse of the stacks of rollers on the pallets. This would therefore have particularly harmful consequences on the quality of the products obtained or on the overall production yield of these rollers.
- the cardboard is a solution perfectly adapted to the needs. It also has the advantage of being relatively cheap.
- a mandrel for supporting a reel of paper, especially toilet paper characterized in that it is formed by the winding of at least one strip of cellulose wadding, said band comprising at least 0.51 grams of a water-soluble material per gram of cellulose wadding, the water-soluble material being determined to impart rigidity and disintegration to the cellulose wadding.
- the cellulose wadding strip comprises at most 1.5 grams of said material per gram of cellulose wadding.
- the band preferably comprises at least two folds of cellulose wadding interconnected by said water-soluble material and at most 24 folds; more particularly between 3 and 8 plies.
- the invention also relates to a method for manufacturing a mandrel as defined above, comprising the following steps: a) providing a first cellulose wadding strip comprising at least one ply, b) providing a second band comprising at least one ply c) depositing a water-soluble material on the first strip, the material being in the wet state, d) assembling and pressing the first band with the second band, the resulting assembly constituting a third band whose folds are bound by the water-soluble material, e) drying the third band, f) helical winding of the third band on it or with a fourth strip, with interposition of an adhesive material, in the form of a hollow tube, g) cutting a section of said tube to form the mandrel.
- a new band of cellulose wadding is associated with the third band to form a new third band, the operation is repeated until the desired band is obtained in terms of rigidity.
- the third band can therefore comprise from 2 to 24 folds.
- the fourth band may be identical to the third band or comprise at least two folds of cellulose wadding interconnected by a water-soluble material.
- the invention is capable of providing a mandrel having both a mechanical strength adapted to the intended use and a greatly improved misfitness with respect to a cardboard mandrel so as to allow it to be directly disposable in a bowl of toilet without risk of clogging the exhaust duct.
- the mandrel according to the invention has a resistance to flat compression and resistance to compression on edge greater than those of a conventional mandrel cardboard.
- FIG. 1 represents a schematic cross-sectional view of a cellulose wadding strip constituting a mandrel according to the invention
- FIG. 2 schematically represents an installation intended to form the cellulose wadding strip of FIG. 1.
- the water-soluble material is based on starch or polyvinyl alcohol.
- Starch comprises natural products of vegetable origin such as starches of wheat, corn, potato, rice, tapioca, sorghum, and the like, constituted by polymers or polyholosides of high molecular weight.
- Starch also means products derived from natural starch, converted by physical treatment, for example heating, physico-chemical treatment or biological treatment, for example enzymatic, derived or modified starches such as cationic starches, anionic, amphoteric, not ionic or crosslinked products and products resulting from the hydrolysis of starch such as maltodextrins.
- the cellulose wadding web comprises a plurality of plies or layers of cellulose wadding, each ply having a basis weight of from about 15 to about 80 g / m 2 and preferably from about 20 to about 40 g / m 2 .
- FIG. 1 there is shown schematically the structure of an example of cellulose wadding strip for forming the mandrel of the invention.
- This structure consists of the stack of 4 folds Cn: C1 to C4, cellulose wadding associated with each other by a water-soluble adhesive material in three adhesive layers Cn: C'1 to C'3.
- Each of the Cn folds of cellulose wadding has a basis weight of 34 g / m 2.
- each of the water-soluble Cn adhesive layers was formed, in part, from a mixture of aqueous glue based on polyvinyl alcohol and polyethylene glycol type SWIFT® L998 / 4 marketed by the company FORBO and of potato starch AMYLOGUM CLS® type marketed by the company AVEBE, and for another part from only potato starch type AMYLOGUM CLS®.
- water-soluble material in addition to the starch, optionally a water-soluble adhesive in a small amount, less than 2%.
- the weight of glue and starch in each of the Cn layers is given in the table below for three examples of the amount of water-soluble material per gram of cellulose wadding: 0.58; 0.91 and 1.13 g / g.
- each of the external faces of this strip was coated with a starch solution without added glue, of the same type as that used in the adhesive layers Cn to form the layers C'4 and C'5.
- Said strip was then wound helically on a cylindrical, according to a technique that may be known from the prior art, with another band obtained in the same way to form a so-called two-strand mandrel, each strip forming a strand.
- the mandrel thus produced was subjected to a series of tests in order to evaluate its mechanical strength and its delectability.
- the compressive strength was measured at both flat and edge of the mandrel, using the following method.
- the mandrel to be tested is first cut in a cylindrical portion delimited by two opposite faces, perpendicular to the axis of the cylinder, said portion having a length of 50 mm in a direction parallel to the axis.
- This cylindrical portion is then positioned between the two metal plates of a dynamometer, said plates being parallel to one another and spaced apart at a distance slightly greater than the length of the cylindrical portion, in the case of measuring the compression on singing or its diameter, in the case of measuring the flat compression.
- the cylindrical portion is arranged to orient the axis of the cylinder in a direction perpendicular to the plane formed by one or other of the trays.
- the resistance opposite the mandrel is measured to its maximum, that is to say just before the mandrel is irreversibly destructuring.
- the cylindrical portion is arranged to orient the axis of the cylinder in a direction parallel to the plane formed by one or other of the trays.
- the edge compressive strength of the mandrel according to the invention is also greater than that of a similar cardboard mandrel. Regarding the constraints on storage, the mandrel according to the invention is also quite satisfactory.
- the power of deletability of the mandrel was measured in accordance with standard NF Q34-020 with agitation.
- mandrel according to the invention disintegrated completely at least 5 times faster than a similar cardboard mandrel formed of a single web of weight equal to 280 g / m2, either with stirring or without stirring. It is also observed that the mandrel began to disintegrate in the water at least three times faster than a similar cardboard mandrel obtained by winding a single strip of cardboard with a basis weight of 280 g / m 2 .
- similar mandrel means a mandrel having substantially the same diameter and the same length as the mandrel of the invention.
- a mandrel was placed in a domestic evacuation system consisting of a toilet bowl connected to a pipe network with a total length of 18 m.
- a quantity of water was discharged by means of a conventional flushing device opening into the bowl so as to evacuate the mandrel out of the bowl and to cover the entire 18 m of pipes.
- the amount of water required for this evacuation was measured for both a mandrel of the invention and for a similar cardboard mandrel formed of a single web weight of 280 g / m 2 .
- the mandrel In the case of the mandrel according to the invention, it takes about 15 I of water for the mandrel to be discharged from the bowl and travels the 18 m of pipes. In the case of the similar cardboard mandrel, the mandrel does not travel all 18 m of pipelines even after spilling more than 50 I of water.
- FIG. 2 there is shown schematically an installation for forming the cellulose wadding strip constituting the mandrel of the invention.
- a first strip 10 of tissue paper having only a single fold is fed from a first coil 10A towards a sizing station.
- Said station comprises a screen roll 1 immersed in a gluing solution 2 based on aqueous glue and starch contained in a storage tank 3, said roll 1 subsequently transferring said gluing solution 2 onto an applicator roll 4.
- the applicator roll 4 is brought into contact with one of the outer surfaces of this band 10 so as to deposit an adhesive layer on said outer face.
- said first strip 10 is pressed with a second strip 20 of tissue paper fed from a second coil 2OA, so that the adhesive layer is trapped between the two said strips 10 and 20.
- the pressing station is constituted a smooth steel roll and an elastomer roll 6 having a hardness of about 95 shore A, separated so as to create a nip 7 through which the assembly of the first and second webs 10 and 20.
- Said third strip 30 is then heat-dried at 140 ° C. by passing inside a calendering station 8 formed of two heated rolls and finally wound up in the form of a third roll 30A.
- a calendering station 8 formed of two heated rolls and finally wound up in the form of a third roll 30A.
- this third coil 3OA may be necessary to use this third coil 3OA in place of the first 10A and / or the second coil
- each of the outer faces of the resulting strip is coated with one or more starch-based layers, which will give it an improved rigidity.
- the starched strip is the basic material used in forming the mandrel.
- This type of mandrel is generally formed by the helical winding of one or more strips around a shaft.
- the resulting hollow tube is then cut into sections of equal length, each of the sections forming a mandrel according to the invention.
- an ideal solution is to use between 2 and 24 layers of tissue paper, and preferably between 3 and 8 layers of tissue paper.
- the strip will be impregnated with water-soluble starch-based material at a rate of at least 0.51 g of starch per gram of cellulose wadding.
