Definitions

  • the invention relates to a stack of flexible sheets and absorbent folded.
  • the invention relates more particularly to a stack flexible and absorbent sheets, in particular of cotton wool cellulose, which has a longitudinal fold line forming longitudinal border and at least one transverse fold line perpendicular to the longitudinal fold line and which are all identically folded, of the type in which the fold lines longitudinal and transverse of a folded sheet upstream of the stack are not adjacent to the fold lines longitudinal and transverse respectively of the folded downstream sheet previous, and of the type in which the longitudinal fold line of a folded upstream sheet is parallel and opposite transverse to the longitudinal fold line of the sheet folded downstream previous, and the transverse fold line of the upstream folded sheet is parallel and longitudinally opposite to the transverse fold line of the downstream folded sheet.
  • These sheets can be used in particular for towels table. They then consist of four flexible panels which are separated from each other by a longitudinal fold line and a transverse fold line.
  • the sheets can be simply placed one on top of the other. the others, the longitudinal fold and the transverse fold of a sheet upstream then being superimposed with the longitudinal fold and the fold transverse of a downstream sheet respectively.
  • the sheets can also be stacked so that the fold transverse of the upstream sheet is superimposed on the opposite edge of the transverse fold of the downstream sheet, the longitudinal folds of the sheets upstream and downstream being superimposed.
  • Another way to stack the sheets is to entangled.
  • Such stacks of folded and tangled sheets are used in particular for hand towels in the field communities.
  • the downstream sheet of the stack is placed directly on a flat surface which is substantially horizontal, the stack extending vertically upwards.
  • Another common solution for napkins is to have the stack of sheets not tangled inside a distributor which consists of a body whose cross section transverse corresponds substantially to the outline of the leaves.
  • a pusher provided with elastic means is located at one of the ends of the body and it allows to push longitudinally the downstream sheet of the stack towards the other end which has an opening for gripping the first leaf.
  • Such a dispenser is generally arranged so that its longitudinal axis is substantially horizontal.
  • the stacks have a high number of leaves.
  • such stacks are not symmetrical by relative to their main stacking axis. Indeed, they are not geometrically symmetrical because the thicknesses of the folds longitudinal and transverse of a leaf are greater than the one corresponding to the overlapping of the sheet panels folded, which causes a decrease in the distribution of their mass relative to the stacking axis because the folded edges contain more material and are heavier than the edges free of folded sheets.
  • the asymmetries of the stack result in unbalance the stack and, if necessary, cause its tilting when placed vertically on a surface horizontal.
  • the sheet located upstream of the stack is not not flat because the overlapping of the folded borders causes a "heightening" of its borders with respect to the unfolded edges. This does not minimize the longitudinal size of stacking and can disrupt the operation of the dispenser flexible sheets when such a dispenser is used.
  • Stack asymmetries can also block the distributor in which it can be placed.
  • the downstream sheet of the stack when the upstream sheet of the stack is pressed against the end of the dispenser having the opening, the downstream sheet is not perpendicular to the longitudinal axis, the thrust forces applied by the elastic means being then not evenly distributed on the downstream sheet which promotes dysfunctions, and in particular the jamming of the pusher, or the crumpling of the sheets downstream of the stack.
  • the invention proposes a stack of flexible sheets of the type described above comprising the characteristics of the characterizing part of claim 1.
  • the stack has a geometric symmetry as well as a distribution of the mass of the folded flexible sheets which allow the stack to remain balanced with respect to the stacking axis, regardless of the number of flexible sheets folded.
  • the sheets consist of at least one ply of material flexible and absorbent. When there are several, they can be linked to each other, for example by bonding or any other mechanical bonding process.
  • stacks of flexible sheets and absorbent, especially in cellulose wadding are made after the folds of the sheets, or during the folding in the case of entanglement.
  • Flexible sheets can be square or rectangular and, for example, may have two fold lines, one longitudinal, the other transverse.
  • Figure 1a shows a flexible sheet 20 square on which is materialized a first longitudinal fold line 22 which separates two flaps 24 and 26 which are symmetrical with respect to the other.
  • Figure 1b shows the flexible sheet 20 folded in half whose longitudinal fold line 22 forms a border longitudinal 28, and on which is materialized a line of transverse folding 30 which delimits two panels 32 and 34 symmetrical to each other.
  • Figure 1c shows the flexible sheet 20 on the point to be folded into four equal parts and which will be designated in the continuation of the description by reference 36.
  • the fold line transverse 30 forms a transverse border 38.
  • the sheet flexible folded 36 then has a longitudinal edge 40 and an edge transverse 42 which are each formed by the superposition of four superimposed free edges of the flexible sheet 20.
  • the line of longitudinal folding delimits two flaps whose dimension transverse of one is different from the transverse dimension of the other.
  • the folded flexible sheet may also have two lines of transverse folding to form a central panel and two flaps end which extend either each facing the same face of the central panel to form a so-called "C" fold, ie each facing one of the faces of the central panel to form a folding says "Z".
  • references designating identical parts of each stack sheet will have three numbers, both first allowing the identification of the part of the sheet, the third and last digit to identify the sheet to which this reference belongs to.
  • Figure 2 shows the stack 50 of three sheets folded 361, 362 and 363 according to the state of the art.
  • the borders longitudinal 281, 282 and 283 are superimposed and so are even transverse borders 381, 382 and 383.
  • FIG. 3 represents a stack 50, according to the state of the technique, a large number of folded sheets 36. It illustrates the imbalance of the stack 50 with respect to an axis stack V which is here substantially vertical. When this imbalance becomes greater than a limit value, stacking 50 tilts and causes the folded sheets to fall 36.
  • the invention proposes to balance it.
  • the longitudinal fold line 22 of a sheet upstream of the stack should not be adjacent to the line longitudinal folding 22 of the previous downstream sheet.
  • Figure 4 shows a first example of a stack 50 according to invention of folded sheets 36.
  • the fold line longitudinal 222 of the intermediate folded sheet 362 is here angularly offset, by an angle ⁇ 1 around the vertical axis V, relative to the fold line 221 of the downstream folded sheet 361.
  • the longitudinal fold line 223 of the upstream folded sheet 363 is angularly offset by an angle ⁇ 2 around the axis vertical V with respect to the longitudinal fold line 222 of the intermediate folded sheet 362 and so on, the angles ⁇ 1, ⁇ 2 and following are preferably equal.
  • the angular offset can vary between a few tenths of angle degrees and 180 degrees.
  • the axis of such a stack 50 is substantially coincident with the vertical axis V. So, when the sum of the angles ⁇ is equal to 360 degrees, the stack 50 is balanced and does not risk to tip over.
  • the angle ⁇ of the longitudinal fold line 222 of the intermediate folded sheet 362 with respect to the line of folding 221 of the downstream sheet is equal to 180 degrees which corresponds to a U-turn.
  • FIG. 5 represents this second example of embodiment.
  • the longitudinal fold line 222 of the sheet intermediate 362 is parallel and opposite transversely to the fold line 221 of the downstream sheet 361
  • the fold line transverse 302 of the intermediate sheet is parallel and longitudinally opposite the transverse fold line 301 of the downstream sheet 361.
  • the stack 50 is balanced.
  • This second example of embodiment makes it possible to minimize the transverse size of the stack 50. Indeed, this size corresponds substantially to the transverse dimension folded sheets 36, whereas in almost all other cases, the transverse dimensions correspond substantially to a disc whose diameter corresponds to the diagonal of the folded sheets 36.
  • the folded sheets 36 successive can be entangled one in the other.
  • downstream folded sheets 361 and upstream 363 are entangled in the intermediate folded sheet 362.
  • the upstream panel 341 of the downstream sheet 361 and the panel downstream 323 of the upstream sheet 363 are placed between the panels downstream 322 and upstream 342 of the intermediate folded sheet 362.
  • the entanglement of the folded sheets 36 allows, in particular when the stack 50 is placed in a dispenser, that the downstream panel 323 of the upstream sheet 363 drives (thanks to friction forces) the upstream panel 342 of the folded sheet intermediate 362 outside the opening allowing gripping folded sheets 36.
  • FIG. 7 to 10 The stack 50 according to the second exemplary embodiment of the invention is shown in Figures 7 to 10.
  • Figure 8 illustrates the stack 50, in particular the folded sheet 36 above located on the top of the stack 50.
  • the height of the stack measured between the center of the lowest bottom folded sheet and the center of the highest top 36 folded sheet corresponds to a first height H1.
  • the height of the stack measured between a corner of the lower folded sheet and a corner of the upper folded sheet 36 corresponds to a second height H2 greater than the first height H1.
  • the curved shape of the folded top sheet 36 is due overlapping edges 28 and longitudinal edges 40 and 38 edges and 42 transverse edges respectively which are thicker than the simple superposition of the four thicknesses of the flaps 24, 26 and panels 32, 34 of the sheet flexible 20.
  • This curved shape does not, however, minimize the vertical size of the stack 50.
  • Figure 9b shows in cross section the third embodiment of the stack 50.
  • the sheets folded 36 are entangled in each other.
  • the invention also proposes, in accordance with FIGS. 11 to 14, to shift transversely, by a distance "x", of the order of a few millimeters, towards the outside of the stack, the border longitudinal 282 of the intermediate sheet 362 relative to the longitudinal edge 401 of the downstream sheet 361, and so on.
  • each longitudinal border 28 can extend vertically in an area whose height here is twice the thickness of a folded sheet 36 or eight times the thickness of the sheet flexible 20. In general, the height of these areas is greater than the thickness of the longitudinal edges 28.
  • the flexible sheets folded 36 therefore have, in a cross section shown in Figure 13, a horizontal cross section.
  • the invention offers, in addition to the transverse offset of the folded sheets 36, to shift longitudinally, by a distance "y", of the order of a few millimeters, towards the outside of the stack, the border transverse 382 of the intermediate sheet 362 relative to the transverse edge 421 of the downstream sheet 361, and so on.
  • the top folded sheet 36 of the stack 50 is then flat in accordance with FIGS. 16 to 18.
  • the height H1 of the stack 50 thus produced is then minimal.
  • a first step is to fold in the direction longitudinal of two separate flexible strips which can be made of several thicknesses of flexible material, around a longitudinal fold line 22 so as to produce two flaps 24 and 26 which may be advantageously symmetrical relative to each other, especially in the case of towels square or rectangular table.
  • the direction of folding of the flaps 24 and 26 relative to the line of longitudinal folding 22 can be identical for each of the two strips of material.
  • the method according to the invention comprises a step which consists in returning longitudinally one of the two bands so that the longitudinal edges of each of the two strips be located on the opposite side with respect to the strip to which it belongs.
  • the direction of folding of the flaps 24 and 26 relative to the line folding 22, of the method according to the invention can also be opposed for each of the two material bands. So the borders longitudinal of each of the two bands are located on the side opposite to the band to which it belongs.
  • the second step allows cuts to be made transverse at regular intervals so as to achieve sheets 20 folded along fold line 22.
  • the third step is to fold the sheets 20 folded around the transverse fold line 30 so that make the folded flexible sheets 36.
  • the fourth and last step allows to realize stacking and entangling of the folded flexible sheets 36.
  • This process makes it possible to obtain a stack 50 of sheets flexible folded 36 which is balanced.
  • two successive flexible sheets 36 can be offset longitudinally and / or transversely relative to each other so as to reduce the height of stacking 50.
  • FIG. 19 schematically illustrates an installation 60 allowing the implementation of the method described above for the production of stacks 50 of folded sheets 36 and entangled.
  • the installation 60 consists of mainly two reels 62, an embossing unit 64, a longitudinal cutting unit 66, a folding unit longitudinal 68 and a unit 70 for transverse cutting, transverse folding and stacking with entanglement.
  • This example is not limiting.
  • Each reel 62 has a reel 72 of material flexible such as cellulose wadding. Strip of material flexible of each coil 72 is unwound and passed into the embossing unit 64 which makes it possible to associate the two strips of so as to produce a single strip which is here two thicknesses.
  • the embossing unit 64 consists of two cylinders. The unit of embossing 64 may also include a bonding device which improves the resistance of the two thicknesses of material flexible to each other.
  • the single strip is then cut longitudinally from so as to make an upper strip 74 and a lower strip 76.
  • the installation 60 can simultaneously carry out several stacks 50. Indeed, the upper bands 74 and lower 76 are cut longitudinally a second time so as to make strips whose width corresponds to the dimension transverse of the flexible sheet 20.
  • the longitudinal folding unit 68 of the installation 60 realizes then folding around the fold line 22 of the strips upper 74 and lower 76 according to a known method.
  • the lines folding 22 then delimit two flaps 24 and 26 on each of upper 74 and lower 76 bands.
  • the folding of the upper strip 74 consists in folding the flap 26 over the flap 24 and folding the lower strip 76 consists in folding the flap 24 over the flap 26.
  • the longitudinal fold line 22 of the upper strip 74 is substantially opposite, with respect to the lower strip 76, to the longitudinal fold line 22 of the lower strip 76.
  • Unit 70 cuts the strips transversely upper 74 and lower 76 for making folded sheets 20 longitudinally and then folds the sheets 20 transversely in sheets 36 and stack them.
  • Unit 70 also allows tangle of sheets folded 36.
