Embodiment approach

[0052] The illustrated diaper 1 generally comprises a front region 2, a rear region and a crotch region 4 between the front region and the rear region. In the most common form, a diaper comprises a liquid-permeable inner cover 5 , a liquid-impermeable outer cover 6 and an absorbent core 7 arranged between the inner and outer covers. The diapers will wrap around the lower torso of the wearer like a pair of absorbent shorts. The front region 2 and the rear region 3 may have a different material composition than the crotch region, eg only the crotch region with a liquid impermeable material.

[0053] The front region 2 and the rear region 3 are joined to each other along two opposite side edges 2a and 2b and 3a and 3b to form a waist opening 8 and two leg openings 9 . For example, the front and rear regions 2 and 3 are joined together along the side edges 2a, 3a and 2b, 3b by adhesive, ultrasonic welding, heat sealing, etc., so as to form the side seam 10 . As shown, the front ...

Abstract

A method for manufacturing an absorbent hygiene article comprising a plurality of components that are joined together during the manufacturing process. Thermochromic fibres are incorporated in a component web, component or a selected area thereof, said thermochromic fibres being adapted to change colour between a contrasting colour to a less contrasting colour. A colour change of said thermochromic fibres is induced during one step of the manufacturing process and the presence of the thermochromic fibres being in their contrasting state is detected by a detection means. A measure in the process control is actuated in response to the detected presence of thermochromic fibres in their contrasting state.

Description

technical field [0001] The present invention relates to a method for the manufacture of absorbent hygiene articles, such as diapers, diapers, sanitary napkins and incontinence guards, which articles comprise a plurality of component parts which are bonded to the Together. The present invention provides a method for improving the control of certain manufacturing steps. Background technique [0002] Absorbent articles consist of multiple parts - such as textile materials, absorbent layers, etc. that make up the outer and inner covers of the article - that are quickly joined during manufacturing, for example by processes such as thermal bonding, ultrasonic welding or gluing . Other components such as elastic threads, securing tabs, waistbands, side panels, straps, etc. may also be incorporated into articles such as diapers, diapers, and incontinence guards. All of these parts must be used and fixed in the correct position on the article. During the manufacture of absorbent ...
