may have other configurations for depositing granule charges in different patters as described in more detail below in operation the servo motor is controlled to cause the pocket wheel 36 to rotate in direction 41 in incremental steps of one sixth of a circle or 60 degrees in this case in other words the pocket wheel is incremented through 60 degrees and then stops for a predetermined time before being incremented again through 60 degrees and so on the time between incremental rotations as well as the speed of rotation during incremental rotations can be controlled to correspond to a given production rate fig3 illustrates in more detail the high speed granule delivery system 28 for depositing a charge of granules onto a moving asphalt coated strip 32 the system 28 comprises a granule hopper 29 only the lower portion of which is visible in fig2 having a nozzle or mouth 34 the mouth 34 of the hopper is generally defined by the wall 35 on the right and the angled hopper wall 30 on the left so that granules 31 in the hopper are constrained to flow downwardly to the relatively narrow mouth 34 of the hopper 29 under the influence of gravity a pocket wheel 36 is rotatably mounted at the bottom of the hopper adjacent the mouth 34 the pocket wheel 36 in the illustrated embodiment is formed with a hub 37 that is mounted on an axle 38 which in turn is journaled for rotation within a bearing assembly 39 the bearing assembly 39 is mounted a side wall 25 fig2 of the.
