Title: ,,The way, the method of unrolling elastic material in the industry of expendable baby napkin production"

The method consists in application of the rule of unrolling elastic material elastic (lycra, spandex, etc.) from immovable, for example, conic shaped rollers in the industry of expendable baby napkin production. Immovable material with approachable endings enables inclusion of that material and bonding thereof in the course of a production line, so production process interruption is avoided and no costs related thereto are incurred. Currently, material rollers are movable and the process of bonding consists in interruption of a production process and in replacement of empty rollers with new ones on which material is rolled.

The second picture shows the method of unrolling EP05460016 (EU) using a unwinding stand W118716 (PL), PL66923.

Delivering method of elastic material focuses on reducing the cost of the product unit.
The presented figure shows:

1. Elastic spandex material – 280D to 1120D, in the form of thread-wound on the cylindrical or
conical rollers. The raw material may be supplied by many manufacturers, but it should have the
both ends of the material, approachable on the reel (2d,2c) to make connection (2b).

2. The unwinding stand of elastic material – according to the design W118716, made from aluminum profiles, meeting the standards of DIN EN 12020-2.

The Advantages of the method of unrolling EP05460016 using unwinding stand:

- The mechanical design of the line remains unchanged
- Constant tension rubber bands, which meets the requirements of quality and process
- It does not require electrical power and storage of spare parts
- Round holes prevent material falling or tangling thread
- Possible rupture of the material do not cause run away the material after the unwinder. Material is easy to threading and connecting without the extended stoppage.
- Low price, ease of installation, reliability and significantly reduce the cost of stoppages and
discarded diapers
- Depreciation period of equipment and installation costs is about 6 months

In case of conical bobbins, material should be stable unwound without rupture to the speed of
3000 pads per minute.

Mounting and utilization.

Mounting of unwinding stand needs the adaptive elements for production line – brackets and guides to
delivering the free material to unwinder and the line conveyor. Often this is a separation guide for threads
before unwinder and an separating roll at unwinder. Due to various types of production
lines and used unwinders, these elements must be designed individually.
