Appeal No. 1996-2624
Application No. 08/186,352
includes a transfer drum [18] having suction segments [19,
19']
(col. 4, lines 49-53). A pair of feed rollers [34] and a
carrier [5] are operated in sequence with the rotation of the
transfer
drum [18] to supply adhesive-coated reinforcing sheets [B] and
carrying handles [T], respectively, to the suction segments
[19, 19'] of the transfer drum. As the drum rotates, it
applies the reinforcing sheets [B] and carrying handles [T] to
a traveling web [32] of bag-making material (Figures 1 and 2).
In order to increase the pitch [t, Fig. 2] of the handles
on the web [32], the transfer drum is non-uniformly rotated
between the various transfer stations (col. 5, lines 33-51) .2
In order to provide the desired non-uniform rotation, Bosse
uses a planetary gearing system [33], including planet gears
[45, 46] carried by a rocker arm [48], and a cam plate [49]
By "transfer stations" we mean those locations spaced about the2
periphery of the transfer drum at which the reinforcing sheets [B] and
carrying handles [T] are individually transferred to the transfer drum [18]
and at which the reinforcing sheet-carrying handle combinations are
transferred to the traveling web [32].
