DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a production line for the manufacture of absorbent disposable articles, such as diapers, sanitary napkins and incontinence guards, wherein the production line includes a conveyor path on which a web of material is moved through the production line, and a row of mutually sequential devices are arranged in the direction of web movement for carrying out different operations included in the manufacture of the absorbent article, these devices being carried on rectangular support plates which are attached to vertical posts which are placed in a framework on mutually the same side of the conveyor path and sequentially in a direction which extends parallel with the direction of path movement.
BACKGROUND OF THE INVENTION
Absorbent disposable articles are typically produced by taking a web of material from a storage reel and moving the web past a number of devices which perform different operations in sequence, such as placing absorbent bodies on the web, laying-out elastic, applying glue, applying further webs of material, compressing absorbent bodies, and heat-welding or ultrasonic-welding devices, and so on. In production of this nature, the production line has been traditionally constructed as one single unit. In recent times, production development has accelerated within this particular technical field, necessitating comprehensive reconstruction of the production lines. However, production lines of unit construction are less suitable for reconstruction and as a result, it has taken much too long to introduce new or modified products onto the market, and it has often been necessary to refrain from making small improvements to existing products, because of the radical changes in the production lines that such an improvement would occur, while, at the same time, the long nonproductive times caused by such reconstruction would prevent the demand of such products on the market being met, resulting in loss in profits and, in the longer term, perhaps also a loss in the share of the market.
The European Patent Application No. 93850174.9 teaches a production line for the manufacture of absorbent disposable articles which overcomes these drawbacks to a great extent. The various working devices of the production line are carried by mutually identical module plates which can be mounted in any desired position in a framework which extends along the production line. This design greatly facilitates reconstruction of the production line, while enabling the production line to be radically increased by adding further working devices thereto, without needing to make large modifications.
SUMMARY OF THE INVENTION
The primary object of the present invention is to facilitate still further reconstruction of a production line and the addition of further working devices, in comparison with the aforesaid known production line. A secondary object of the invention is to enable the carrier plates to be mounted in the production line more easily and enable the work to be carried out by unskilled workmen.
In accordance with the present invention, these objects are achieved with a production line of the kind defined in the introduction which is characterized in that the production line includes carrier plates of mutually different sizes; in that the length of each side of a carrier plate is essentially a multiple of the length of the smallest side of the smallest carrier plate; in that the distance between the vertical posts is essentially a multiple of the length of the smallest side of the smallest carrier plate; and in that each carrier plate includes a pair of opposing sides whose lengths are essentially equal to or essentially form a multiple of the smallest distance between the posts. This construction enables the carrier plates to be given to a very large extent a size which corresponds to the size of the working device carried thereby, therewith reducing the space required on the framework for the carrier plate carrying the working device as compared with a carrier plate wh
