examiner has proposed.
We further cannot agree that the claimed stop lever is
simply "another holding lever" which can, as an "obvious
matter" be simply "duplicated" as the examiner contends. The
claimed first, second and third groups of levers all have
clamping
segments 44 thereon which function to clamp and hold the pipe.
The stop lever, however, is set forth in independent claim 1
as:
at least one stop lever (42), which is supported
on the conveying carriage (15) to be movable from a
position of contact with an annular elevation (36)
on the downstream end of the corrugated pipe (33) to
a position of release from the corrugated pipe (33)
and which in the position of contact adjusts an
initial position of the pipe with respect to the
direction of the axis (8).
The function of this stop lever is described on page 10 of the
specification in the following manner:
Now a pipe 33, with its spigot 34 ahead, is pushed
through the pipe guiding socket 31 and then through
the pipe guiding socket 32 in the direction of
production 11 until the first annular elevation 36
of the pipe 33 comes to bear against the stop
segments 45 of the stop levers 42. This is where the
pushing motion is being stopped. The pipe 33 has
taken its position referred to the direction of the
axis 8. A signal of the sensor 44c confirms the
