swatches are spaced from one another and is silent as to the relative rates at which the ribbon is
fed by rollers 12, 13 and the wrapping sheets are fed by rollers 24, 25.
The examiner, finding that Petersen discloses the method as recited in claim 17, with the
exception of the limitation that the first feed rate is greater than the second feed rate, relies upon
the teachings of Dallaserra to remedy this deficiency. Dallaserra discloses a method for
packaging an interior document in a sealed mailer so that it is free to move therein and is not
secured to the outer sheets, i.e., for introducing a sheet section between the upper and lower
sheets, without the section being held by the seal, but, on the contrary, remaining free in the
interior of the sealed mailer so as not to interfere with its removal by the addressee (column 5,
lines 42-49). Dallaserra's method involves feeding continuous upper and lower sheets 11, 12 at
a first velocity V1 and feeding a continuous intermediate sheet 10 at a second velocity V2
between the upper and lower sheets, severing the intermediate sheet into discrete lengths E2
and feeding the upper and lower sheets and the lengths of intermediate sheet to a sealing station
20 to unite the upper and lower sheets over the entire periphery of each of their sides by virtue
of pressure rollers 22. In order to achieve the stated objective of introducing the intermediate
sheet section between the upper and lower sheets such that it is free to move therein and is not
secured to the outer sheets at the sealing station, the rollers 13 which feed the upper and lower
sheets 11, 12 have a tangential velocity V1 which is greater than the velocity V2 at which the
sheet 10 is fed to the rollers 13 (column 5, lines 50-68).
