Benefits of technology
The present invention provides a pants-type diaper or sanitary panty with side seams that are more advantageous than peeling forces and have an aesthetically attractive appearance. This is achieved by placing folded bands of flexible material between the front and rear side parts of the blank and fastening them to the side parts. The invention also relates to an absorbent article with separate pieces of material that join the side parts and are subjected to shear forces when worn. The separate pieces of material are non-elastic and attached to the inner surfaces of the side parts using releasable and refastenable fastener means.
Problems solved by technology
Neither are the seams attractive from an aesthetic point of view, which is a negative feature from a commercial aspect.

Embodiment Construction
[0020]FIG. 1 illustrates schematically the plant machinery for manufacturing pants-type diapers, including a conveyor path 1 by means of which casing material 2 taken from a storage reel 3 is conveyed from left to right in FIG. 1. Located downstream of the reel 3 is a device 4 which lays absorbent bodies 5 at regular intervals on the underlying web of casing material 2. Located downstream of the device 4 is a device 6 which lays elastic elements in a specific pattern onto or immediately above the web of casing material 2. These elastic elements, of which one is shown schematically in by reference numeral 7FIG. 1 and which are preferably comprised of elastic threads or ribbons, form the waist and leg elastic of the manufactured pants-type diaper. Located downstream of the device 6 are guide rollers 8 which function to guide a second web of casing material 9 onto the first web 2, while downstream of the guide rollers 8, there is located a device 11 which brings the webs of casing mate...

Abstract
A method of manufacturing an absorbent article, and an absorbent article, in the form of a pants-type diaper or a sanitary panty, starting from a flat blank which includes an elongated absorbent body enclosed between two casing sheets which at opposing front and rear end parts of the absorbent body have side parts which extend laterally beyond the body on both sides thereof. The method includes the step of folding the blank around a transverse axis so that the end edges of the side parts lie edge-to-edge. At least one folded band of flexible material is placed between each pair of front and rear side parts which lie opposite one another in the folded state of the blank, and the free ends of the bands are fastened to adjacent side parts.
Description
TECHNICAL FIELD [0001]The present invention relates to a method of manufacturing an absorbent article in the form of a pants-type diaper or a sanitary panty, beginning with a flat diaper blank which comprises an elongated absorbent body enclosed between two casing sheets which at opposing front and rear end parts of the absorbent body have side parts which extend laterally beyond the absorbent body on both sides thereof, said method comprising the step of folding the blank about a transverse axis so that the end edges of said side parts will lie edge-to-edge. The invention also relates to an absorbent article manufactured in accordance with the method.BACKGROUND OF THE INVENTION[0002]Present-day all-in-one diapers are being replaced to an ever greater extent with pants-type diapers, or so-called training pants, for slightly older diaper-wearing children. Pants-type diapers have a number of good features. They fit well on the wearer, they are easy to put on and take off with the chil...
