Definitions
- the invention relates to the field of rolls of absorbent paper or other similar material such as a nonwoven, intended for example for wiping. It relates in particular to the field of products for sanitary or domestic use such as wiping rolls or hand towels or toilet paper.
- the rolls consist of a continuous sheet which has one or more plies.
- the sheet is optionally precut into consecutive coupons in the winding direction, and is wound axially, preferably around an axis which may or may not support a mandrel; the roller can thus comprise a central mandrel or not.
- the sheet can be unwound, either from the outer surface of the roll in the direction of the winding, or from the inside, from the center in the axial direction perpendicular to that of the winding of the roll.
- the present invention relates to rollers which are used in central unwinding.
- the roller has a mandrel, we must first extract it. In general, it has been designed so that it can be torn by pulling on its edge; most often at one end of the cardboard helical spiral that forms it.
- this solution is not always satisfactory, since the extraction of the mandrel proves to be sometimes difficult if the rupture zone or zones are poorly formed. Moreover, this action may result in the 'first leaves the roll that become difficult to use.
- the first turns of the sheet being. most often glued to the mandrel, they are unsuitable for any use and are therefore a cause of waste.
- This mandrel is particularly expensive to produce, since generally, composed of two or more layers of cardboard bonded by gluing. It is also most often associated with a “hanging” glue of the first turn of the roll. It is no longer of any use once removed, and therefore becomes waste.
- coils with central unwinding without a mandrel are also proposed. These are a priori easier to implement by the user, since it is no longer necessary to remove a mandrel before they are put into service. To achieve these, one can, in manufacturing, provide a temporary mandrel on which the sheet is wound. The mandrel is then removed, before the coils are conditioned.
- the sheet is cut in line in the running or longitudinal direction, before winding, from a mother sheet of large width, and in as many strips as there are individual rolls to obtain.
- the mother sheet is wound directly on a spindle, also without the interposition of a mandrel.
- the initial sheet which is very wide, is first wound up so as to form a single coil with the final diameter of the individual roll, called "log" in the field. After formation, the log is extracted from the spindle and cut into individual rolls.
- the sheet whether it is cellulose wadding, dry or wet crêpe, dry paper or a nonwoven, has a certain elasticity. Due to the internal stresses of the roll, due for example to the tightening of the sheet on the spindle during winding and / or to the tension of the sheet generated by the unwinding / winding operation by the machine, it cannot normally be avoided. reduction of the central hole by sagging or collapsing in the center of the first turns after the spindle has been removed. This collapse occurs, for example, after extraction of the spindle and / or when cutting the log, by the pressure exerted by the saw.
- the central hole is of small diameter and the first turns remain difficult to access. They come in a tight, helical torch with a low "pitch", not very conducive to easy use. If the diameter of the central hole is larger, it is difficult to avoid associating the first turns between them.
- a bonding agent is used which is deposited directly on the sheet or indirectly via the spindle or one of the winding cylinders, by a suitable system, when the first turns are wound on the spindle. Any other principle of association of the first turns between them, in particular by a mechanical process, is applicable. These first turns are thus consolidated, which together resist the stresses of internal constraints. However, here again, waste cannot be avoided during the commissioning of such a roller.
- the subject of the invention is therefore a roller without a mandrel composed of a sheet of flexible material, such as an absorbent fibrous material with a total grammage between 15 and 300 g / m 2 , preferably between 15 and 100 g / m 2 , formed by winding around a winding axis, which does not have the drawbacks reported above.
- the absorbent material can be cellulose wadding, dry or wet crepe, dry paper or a nonwoven. It can be made up of one or more folds, associated or not, possibly pre-cut into coupons. The material is dry. It is not humid; in particular it is not impregnated with lotion or any other liquid.
- the present application relates to a new method constituting a variant of the methods described in the applicant's previous application.
- the primer is produced by shifting before winding an end portion of the sheet so that one of its longitudinal edges forms a non-zero angle relative to said direction of travel, then the sheet is wound around the axis.
- the sheet is rolled up on a winding support, such as a spindle.
- the end portion is formed by cutting the sheet transversely relative to the direction of travel.

- - Figure 11 shows the machine in the configuration of Figure 9
- - Figure 12 represents a roller obtained according to the method of the invention.
- the paper is for example a cellulose wadding with two plies of 20 g / m 2 each, preferably associated.
- the roll was obtained by winding a large sheet of 2600 mm in width, on a spindle-shaped winding support, for example with a circular section of diameter from 10 to 80 mm. After forming a roll, designated “log” in the field, of 20 cm in diameter for example, the spindle is extracted therefrom and taken to a sawing station. The rolls thus produced are then packaged for shipment. The roller is shown after the walls of the central hole have collapsed in the central direction.
- FIG. 2 shows a roller (10 ') without mandrel resulting from the process of the invention or as described in patent application PCT / FR03 / 01776.
- the central hole is reduced as in the previous case of the prior art.
- the commissioning of the roll is greatly facilitated by the solution of the invention which consisted in forming a primer (10B) for central unwinding.
- This primer is, according to the simplest embodiment, constituted by a portion of the internal end of the sheet forming the roll that is previously, before any collapse of the walls of the central hole, released, and put in protrusion from one of the sides of the roller.
- This primer can be formed either when the roll is formed just before or during the winding of the sheet, or after the roll has been made when the hole is still formed, ie just after cutting, in any condition. preferably, soon after, as described in application PCT / FR03 / 01776.
- this primer (10B) 0.3 to 20 cm long and preferably 1 cm to 15 cm, is formed by a portion of the inner end of the sheet, which has been folded into the direction of the winding axis of the roll and overflows relative to the side.
- This primer thus forms a point gripping means which is flexible at its end and which can easily be folded against the side of the roller, to carry out the conditioning of said rollers before transport.
- the tip is handy and can be easily inserted into a dispenser.
- the length of the primer is chosen in particular for the ease with which it can be grasped and with which it can be introduced into the extraction orifice of a dispenser.
- the length of the primer corresponds to the distance between the end of the primer and the side of the roller.
- the primer can be reinforced with an additional element, coloring for example.
- the primer can be reinforced mechanically by a tongue, or any suitable means, or additional element attached to the sheet and arranged to project from the axis of the roller.
- the added element is then placed on the end of the sheet before winding or after separation of the rollers, projecting from one of the sides of the roll.
- a method of manufacturing the rollers according to PCT / FR03 / 01776 is described below with reference to Figures 3 to 6 which show the essential elements of a roller winding machine. With this machine, a wide sheet 1 is cut online from a mother reel (3), before winding on a spindle (11).
- the width of the sheet in the field of absorbent paper products is for example 2600 mm.
- the sheet is cut in the longitudinal direction of travel by means of blades 5 arranged in parallel, in a plurality of individual sheets (10) whose width corresponds to the width of the individual rolls which it is desired to obtain.
- the cutting means may consist of a series of blades arranged vertically or else discs cooperating with a support cylinder and cutting the sheet. Other means are known to those skilled in the art.
- the sheets (10) are driven towards a device comprising two cylinders (7 and 9) parallel and driven in rotation by motor means not shown. The two cylinders are slightly spaced from each other. Once the sheets (10) in the position of FIG. 3, a spindle (11) forming the winding support is brought into place by suitable means.
- the pin pinches the sheet against the cylinders (7 and 9), as can be seen in FIG. 4. It overlaps the space formed between these two contiguous drive cylinders.
- the spindle thus delimits on one side an end portion (10A) of the sheets (10).
- means (15) are provided which fold the end portion (10A) over the spindle (11). This means can consist of one or more judiciously oriented air jets.
- a pressure roller (13) is lowered to hold the end (10A) of the sheets against the spindle.
- the cylinders (7 and 9) are rotated. These rotate the spindle and the roller 13 on themselves allowing the sheet to be rolled up as seen in FIG. 5.
- the means (15), here constituted by air jets, are inclined on the axis of rotation of the spindle so as to impart to these end portions a movement of transverse movement relative to the direction of movement of the sheets.
- These end portions (10A ⁇ , IOA2, ...) are thus displaced in the direction of the winding axis.
- each end portion, (10A- ⁇ ) for example, overflows on the side in the direction of the neighboring sheet, (10A 2 ).
- the pressure roller (13) immobilizes the different end portions (10A ⁇ , 10A 2 , ...) against the spindle (11). Winding can begin.
- FIG. 7 shows here four rollers (110 ′) being formed by winding sheets (1101 to 1104). The number of rollers may be different.
- the sheets are cut from a wide sheet (110) in the direction of travel (MD) thereof by cutting means shown schematically by discs (105). They are mounted on a spindle or winding support (111) which is rotated in the direction of the arrow by the two cylinders (107 and 109) on which they rest. The cylinders (107 and 109) are themselves rotated by motor means, not shown. A pressure cylinder (113) ensures the cohesion of the assembly.
- FIGS. 8A and 8B the winding of the rollers is finished; the assembly was moved with the spindle over a first distance (L3) determined in the direction of travel (MD) mentioned above, leaving the sheets to unwind.
- the rollers were placed with the spindle on supports (107 'and 109').
- the supports (107 'and 109') are preferably parallel to the cylinders (107 and 109).
- the spindle is driven in rotation a fraction of a turn, in the opposite direction to the initial winding direction, in the direction of the arrow in FIG. 8B to form a loop by unwinding a given quantity of sheet.
- a jack (120) which moves the spindle (111) fitted with the rollers, preferably parallel in the direction of its axis, over a second determined distance (L2) in the direction of the arrow ( CD).
- L2 second determined distance
- the longitudinal edges of the sheets now make an angle ( ⁇ ) relative to the initial direction of travel (MD).
- the angular offset occurs from the blades (105) for the longitudinal section of the sheet (110) which are located upstream of the cylinders (107 and 109).
- This angular offset is preferably done in the same plane as that of the scrolling.
- it can be carried out according to an adapted trajectory having at least components in the directions (MD) and (CD)
- a new pin (111 ') is deposited on the sheets at the cylinders (107 and 109). The sheets are thus pinched between the spindle (111 ') and these cylinders.
- the winding of the rollers (110) ′ is completed in such a way that the end ends or tail portions (110B) of the sheets coated with glue G are fixed on their respective rolls, so that the longitudinal edges of said portions of tail (110B) align as best as possible on their respective roll.
- the edges generated by the cross section do not form a right angle with the edges sheets (110).
- the end portion (110A) which forms the primer thus has a tapered shape conducive to easier introduction into a dispensing orifice of a reel.
- the tail portion (110B) is also tapered and is characterized by this method. The rolls are finished.
- the spindle is separated from the rollers and the primers are released by moving the rollers apart from each other.
- the machine is ready to take up a new set of rollers.
- the first step then consists in folding down the end portions (110A) on the spindle. Because of their inclination relative to the direction of travel of the sheet (angle ⁇ ), these sheet portions (110A) folded over the spindle each form a primer and overlap the adjacent roller. The rest of the sheets which have not undergone this lateral offset are wound, staying perpendicular to the axis of the spindle to form the rolls. It is observed that, with respect to a known roller winding installation, it was sufficient to include a jack (120) which controls the axial movement of the spindle over a short distance.
- the length of the spindle (111) displacement in the axial direction depends on the length of the wire feeder.
- products have been produced on an industrial machine.
- a primer length C of about 60 mm is obtained.
- (C L2xL / L1).
- Figure 12 there is shown a roll with the last sheet
- this angle is complementary to the angle ( ⁇ ).
