SJML-Sdfi WADBING SHEETS FOR THE LINTNG (BF BABY? NAPKINS Fernand Wuhrlin, Usine ties Plis (Eure), Hondouville, France Filed Apr. 1, 1957, 821'. No. 650,017 2 (Jaime (1. 128-284) This invention relates to cellulose wadding bands of a new structure of superposed sheets intended for lining babys napkins; their structure makes them very efficient and of a particularly convenient use.

According to the main feature of the invention the cellulose wadding bands form a succession of rectangular adjoining units, the separation of which is made easier by an interrupted cutting line.

Each unit is provided with two cut-away portions or indentations corresponding to the shape of the upper part of the childs thigh.

Said identations are symmetrical in relation to the longitudinal axis of the unit sheet and, in order to allow a better distribution of the absorption surfaces, they are located forwardly in relation to the transverse axis, that is to say that the unit surface located in front of the childs thighs has a size less than that of the back part.

Owing to this structure, the setting of said units in position is very quick and the absorbing material is at the desired places without providing undesirable over thicknesses.

T line the babys napkins, a unit of the series is normally detached but the number of the superposed sheets in the napkin may vary according to requirements without it being necessary to tear out the intermediate interrupted cutting lines.

According to a variant of the embodiment each piece cut from two adjoining units to provide in each cellulose unit and on either side of the longitudinal axis, the two indentations corresponding to the shape of the upper part of the childs thigh, constitutes a removable piece intended to be inserted at a suitable place within the actual thickness of the unit at the moment of utilization in order to increase the absorption capacity of said unit according to the position of the child.

The invention includes also embodiments comprising at least one of the following features:

(a) The rectangular adjoining units form a succession of units constituting a long band which is manufactured for instance as a roll or as an accordion pleating.

(b) In a series, all the units are identical and have an opening on their joining line with the two adjoining units.

(0) The joining line of the units is cut or perforated at intervals, so as to make it possible to detach easily a unit or a group of units from the remainder of the band.

(d) The cutting line of the units enabling a unit or a group of units to be detached is formed by thinning down by pressure, starting a cut or any other suitable means in order to obtain an easy and clean tear of the units.

(e) The cut-away side portions of the units are located forwardly of the transverse axis.

(f) The bands from which the units are out are formed by superposed bands of difierent widths with the narrower hands sandwiched between the wider bands, so that the units are thicker in the middle than at the edges.

(g) The adjoining units of cellulose wadding composed of superposed sheets have all the same thickness.

(h) Each piece cut out from two adjoining units to provide in each cellulose wadding unit and on either side of the longitudinal axis of the latter, the two arcuate indentations corresponding to the shape of the upper part of the childs thighs, constitutes a removable piece intended to be inserted at a suitable place into the thickness of the unit at the moment of its utilization in order to increase the absorption capacity of said unit according to the position of the child.

(i) Each detachable unit may have a rectangular or trapezoidal shape, a sinuous outline or any shape having an axis of symmetry between the two cut-away portions corresponding to the shape of the upper part of the childs thighs.

(j) The sheets whichconstitute the units are held together by points of stamping preferably located on the edges.

(k) The middle part of the sheets may be embossed or corrugated.

Other particular features and advantages of the invention will appear from the following description and from the consideration of the annexed drawings, which show, by way of examples and without implied limitation, em bodiments of the invention.

In said drawings:

FIG. 1 is a general view of a cellulose wadding band divided into units according to the invention.

FIG. 2 shows on an enlarged scale one of the units out of the band shown in FIG. 1.

FIG. 3 is a sectional view taken along line IIl-lll of FIG. 2..

FIG. 4 shows the part out in two rectangular adjoining units to provide in each unit the side indentations corresponding to the shape of the upper part of the childs thighs.

FIG. 5 shows a rectangular unit with the cut-out piece inserted in the thickness of the unit.

FIG. 6 is a sectional view taken along line Vl-Vl of FIG. 5.

FIG. 7 is a general view of a cellulose wadding band composed of trapezoidal shaped units.

FIG. 8 is a view similar to FIG. 7, the units being cutout from the cellulose Wadding band along a sinuous line.

Referring to FIG. 1, there can be seen a continuous band of cellulose wadding composed, by way of an example, of nine identical rectangular adjoining units 1. Said band 2 may have the shape of a roll or of an accordion pleating.

The joining line of two adjoining units is partly perfo rated, as shown at 3, so that the desired unit or units can be easily detached from the remainder of the band. On each joining line an indentation is cut in each unit, corresponding to the shape of the upper part of the childs thighs.

According to FIG. 3, the band is composed of superposed sheets, so disposed that the thickness in the central area is greater than at the edges thereof. For instance, there are a few sheets outside which have the same width as the band 2 (sheets 5 in FIG. 3), then a few sheets a a little less wide and a few sheets 7 still less Wide. In this way the middle part of the unit which is the absorbing part is the thickest one, while the edges of the band are much less thick and thus cause no inconvenience.

Obviously, a quite dilferent combination of the sheets from that indicated might be adopted.

It will be pointed out that the side indentations 4 are displaced upwards in relation to the transverse axis of the units 1.

According to the alternative form of embodiment shown in FIGS. 4 to 6, there can be seen the part *9 cut from two rectangular adjoining units 1, to provide in each unit the side indentations corresponding to the shape of the upper part of the childs thigh.

' When the unit 1 is used, said part 9 which constitutes a removable part which is inserted at a suitable place between the superposed sheets which constitute the unit 1 is e13 detached at the same time in order to increase tie absorption capacity of the latter.

When the baby is lying down, the removable part 9 is preferably located as shown in dotted lines in FIG. 5, that is to say behind the back. When the child begins to walk the removable part 9 may be located between the two side notches 4 as shown in dot-and-dash lines. It is also possible to locate the removable part 9 higher on the front as shown in broken lines in FIG. 5.

In these examples the joining line of the units is partly interrupted to make the separation easy at the moment of the use, but it may be formed by thinning down by pressure, a starting of a cut or any other suitable means of obtaining an easy and clean tear.

In the example shown in FIGS. 5 and 6 the adjoining units 1 composed of superposed sheets 5 have a uniform thickness which allows the band to be rolled-up during manufacture.

In FIGS. 7 and 8 are shown other alternative forms of embodiments in which the detachable units have trapezoidal shape (FIG. 7) or are provided with joining line with a sinuous outline 30 (FIG. 8).

To hold the sheets attached to one another to a certain extent, stamping points 8 are provided near the edges of the unit.

Moreover it is possible to provide at least certain sheets with an embossed or corrugated structure in the middle part of the unit.

It can be seen that owing to the removable nature of part 9, it is easy, when the childs napkin is lined, to take into consideration the position which the latter will have to assume and to put said part 9 accordingly at the suitable place within the very thickness of the unit.

The invention is not restricted to the embodiments shown and described which have been given by way of examples but it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
