Appeal No. 2001-2320
Application 09/097,295
finding (see pages 2 and 4 in the final rejection and pages 5
through 7 in the answer) that the material flow limit inherently
is exceeded during the strip securing steps disclosed by these
references, wherein material is rolled into gripping or squeezing
engagement with the strips, is reasonable on its face and has not
been cogently disputed by the appellant.
Palmer and Ito are similar to Parsons and Steenstrup in that
they too pertain to the manufacture of composite structures
wherein members are inserted into grooves on a base member and
secured thereto by deforming the base member material adjacent
the sides of the grooves into gripping engagement therewith. Of
particular interest is the manner in which the grooves are formed
in the base members. In Palmer, the grooves are made by passing
the base member (metal strip 10) between a bottom roller 17
having a flat annular supporting surface and constraining side
flange portions 19 and 20, and a top roller 21 having a plurality
of laterally spaced annular ribs 22 which press into and deform
the base member to produce the grooves. In Ito, the grooves are
made by placing the base member (shell 10) on a die 9 and
deforming it from above with a ram-powered punch 11 to produce a
slot or groove 13.
