<p>1507197 Web feeding apparatus H F HOPE and S F HOPE 4 April 1975 [4 April 1974 9 Oct 1974 10 March 1975] 14029/75 Heading B8R Apparatus for feeding a web 15, Fig. 4, along a path 21, 23, defined by a plurality of feed rollers 50, 51; 44, 42... 128, 130; ... 42, 46; 152, 154 and arranged in clusters of satellite gears 28, 98, ... 98<SP>11</SP>, Fig. 1, is provided with a drive for the feed rollers, the drive including power transmission gears 22, ... 54<SP>11</SP>, driven by a drive pinion 18, Fig. 3, either directly or through the intermediary of reversing rollers 56, 56<SP>1</SP> and each power transmission gear is associated drivingly with a cluster of satellite gears through the intermediary of a cluster drive gear 26, 60,... 64<SP>11</SP>. The ratio of power transmission gear p.c.d. to that of a roller driving gear, e.g. 48, is greater than one and may be as high as five. The ratio may vary from cluster to cluster. The web is guided along the path by a system of guide plates 52 and rollers 126, 132 at the turning point of the path.</p> |
