Egg timer-shaped absorbent pad for a pair of nappy-pants, and process for the continuous manufacture of such pads

Claim 1

Process for the continuous manufacture of egg timer-shaped absorbent pads, having a rectangular general shape with two opposite lateral indentations, for a pair of nappy-pants, comprising, in the direction of its length, two end zones and a between-the-legs intermediate zone of width smaller than and thickness greater than those of the end zones, characterized in that in a strip of absorbent material (10) of width greater than the maximum width of the pads to be manufactured, at intervals corresponding to the length of the pads to be manufactured, two opposite incisions (11) symmetrical in relation to the longitudinal median line (12) of the strip and comprising, in the direction of the length of the strip, two diverging parts (13), followed by two converging parts (15) are successively made, in that the two lateral parts (17) of the strip (10), included between each incision (11) and the longitudinal lines (16) connecting between them the successive incisions on the one hand, and the corresponding longitudinal edge (19) of the strip (10) on the other, are folded over each other around the said longitudinal lines and over the median part (18) of the strip situated between the said lines (16), and in that the strip thus folded is cut in the transverse direction at intervals corresponding to the length of the absorbent pads to be manufactured, at the place where the distance separating the opposite incisions (11) is maximal.
