1. CLEAN Products with Feces Trap
For superior comfort, performance, and skin health

2. Objectives: Improved wearer comfort Improved skin health
Reliable product performance
Consumer affordability

3. How CLEAN pants or diapers can help:
Excellent sealing: intimate contact between leg hoops and upper thighs
Excellent body fit: product components connected by „darting“-type connections
Feces are trapped: Leg hoops fit high in the crotch crease, such that they can lift up an attached feces trap sheet to the anus
Lean product and process design: 100% material usage and multi-lane manufacturing options allow affordable pricing

4. This presentation answers the following questions:
How can CLEAN articles be assembled cost efficiently?
How easy is it to put the product on?
How do they fit the wearer, and keep the skin clean?
What is the impact of the new assembly technology on the manufacturing system, particularly on line capacity?

5. BOCO CLEAN products - low cost making:
designed to use 100% of their raw materials; no trimmed off pieces;
made of low cost materials
smaller number of different materials, compared to conventional products

6. - Cost Efficient Assembling: The Backsheet Side -
-in a first step, the leg hoops are fed by a „cut and space“ unit
-as a next component, the backsheet is provided
-with another FLEXIBOND connection, the backsheet is connected to hoops
and sidepanels, whereby the backsheet side is completed
-in a further step, leg hoops and side panels are connected to each other where
they overlap, via „FLEXIBOND“ bonding technology
-in a second step, left and right sidepanels are provided such that they slightly
overlay the leg hoops

7. - Cost Efficient Assembling: The Topsheet Side -
-Elastics are fed in between the 2 topsheet pieces, where they overlap. The
elastics are fixed by the spiral or spray glue
-the topsheet, consisting of 2 pieces - each one slightly wider than one half
of the centre piece width - comes in as first component on the topsheet side.
Glue (beads and spray or spiral) is applied on one of the topsheet pieces

8. - Assembling the Topsheet Side -
-next, the topsheet is partly covered with glue
-finally, some glue on the core makes the topsheet side assembly ready
to be combined with the backsheet side
-the core is laid down onto the glued topsheet
-the topsheet, consisting of 2 pieces - each one slightly wider than one half of the centre piece
width - comes in as first component of the topsheet side. Glue (beads and spray or spiral) is
applied on a topsheet piece.Stretched elastics are fed in between the 2 topsheet pieces, where
they overlap. The elastics are fixed by the spiral or spray glue
around a slit in the combined topsheet. The non-glued elastic areas are held
in the channel formed by the glue beads connecting the 2 topsheet halves

11. -after cross directional folding, the product can be packed
-the assembled article is folded along two longitudinal foldlines towards
the topsheet side, thereby engaging the „pickup glues“

12. by unfolding the product and closing the fasteners
BOCO CLEAN products are easy to put on:
by unfolding the product and closing the fasteners
around the wearer‘s legs, the feces trap sheet is
moved to the right position
BOCO CLEAN products fit perfectly even when loaded:
„belt-like fit“ around waist and legs keeps product
up and close to the body
anchoring of the feces trap sheet to the leg hoops ensures accurate positioning, for a clean skin

by unfolding the side panels, the leg hoops are errected and stretched, thereby lifting up the feces trap sheet

Due to the action of
leg hoops and the
pickup points, the
feces trap sheet is
pulled up against the
skin of the wearer.
There are no
extra efforts required
to bring the opening
in registry with the
anus.

16. BOCO CLEAN products can be made „Side by Side“
more than one product of a size can be made side
by side simultaneously
products with different waist circumferences can be
made side by side simutaneously
see also GB (A) for reference

17. Assembly - Impact on line capacity -
CLEAN product:
narrow while in process
wnew
Conventional product:
side panels and ears in an open
position until the product is
completely assembled
i. e. it is wider while in process
wconv

18. Assembly - Impact on line capacity -
wnew w D
wconv
Width w is saved in process.
This allows to multiply line capacity! D

19. Assembly - Impact on line capacity -
2 or
a standard line can make one
product at a time, or
3 or
more
