Problems solved by technology

This is a problem in terms of cost and in terms of environmental pollution or pollution to other components in the production line
Another problem posed by SAP particles is that they wear down the mold and thus make it necessary to replace the mold without replacing the article being manufactured

Embodiment Construction

[0019] The pad forming wheels 1 , 2 are arranged side by side with a nip formed between them. The term "nip" denotes the position where the outer peripheries of the wheels 1, 2 are closest to each other.

[0020] exist figure 1 In the shown apparatus, the second core parts formed on the second liner forming wheel 2 are transferred to the first core parts formed on the first liner forming wheel 1 and are drawn by the suction produced by the suction box 13. The suction remains thereon until the composite core comprising the first and the second core part is conveyed onto a compression device 17 consisting of two rollers 18 , 19 . Near the nip between the wheels 1 and 2, and between the nip and the compression device 17, a web of shell material 20, such as tissue, from a supply roll (not shown) is applied to the outside of the composite core.

[0021] After compression, the composite core passes through a cutting device 21 and is then transferred to an accelerating device 22 ...

Abstract

The invention relates to a mat-forming wheel (1,2) for forming air-laid absorbent cores for sanitary absorbent articles, such as diapers, sanitary napkins, incontinence protectors and the like, said wheel comprising a series of moulds (31) along its peripheral surface, each mould comprising up- standing walls and a bottom (29). According to the invention the up-standing walls of the mould is formed in an element (30) of a flexible material, which element is releasably attached to a foraminous substrate (29) of rigid material, which runs along the whole circumference of the mat-forming wheel (1,2).

Description

technical field [0001] The present invention relates to a liner forming wheel for forming an airlaid absorbent core for use in hygienic absorbent articles such as diapers, sanitary napkins, incontinence guard articles and the like, said wheel comprising along its peripheral surface A series of moulds, each mold comprising upstanding walls and a base. The invention also relates to a method of forming an absorbent article using such a pad forming wheel. Background technique [0002] Pad forming wheels are components that are frequently found in production lines for the manufacture of disposable sanitary absorbent articles such as diapers, sanitary napkins, incontinence guards, and the like. Sometimes these articles are manufactured in very small batches. Those batches may consist of different types of articles or different sizes of the same article. This is often the case when different batches are to be produced after each other on the same production line, which involves ...
