Appeal 2006-2308
Application 10/343,154
BACKGROUND
The invention relates to a process for producing an adhesive closing
part with laterally symmetrical interlocking structures integrally connected
to a backing. Each interlocking structure has a stem part, a head part at one
end of the stem part, and a base part at an opposite end of the stem part
where the stem part is connected to the backing. The process involves
supplying moldable material to a shaping zone between a pressure tool and a
molding tool to form the backing. The molding tool contains mold cavities,
having a rotationally symmetrical hyperboloid shape. According to
Appellant, the shape of the mold cavities facilitates removal of the
interlocking structures from the mold cavities, even at very high production
rates. In addition, Appellant maintains that the interlocking structures
formed by the claimed process adhere well and can be joined easily to one
another, since the interlocking structures are properly formed and are not
damaged during removal from the mold cavities.
DISCUSSION
