  • the upper surface of the carton cover 14 comes into engagement with the oversped closer and hold-down belt 64.
  • the spring loaded central pulley 72 insures firm contact of the belt 64 with the carton cover, and the differential speed ratio driving mechanism in the housing 84 imparts forward travel to the cover 14 of a velocity slightly greater than the velocity imparted to the carton bottom by the conveyor 36. This serves to properly align the locking tabs 38 depending from the front fold-down flap 28 of the cover with the locking apertures 20 of the carton bottom.
  • the tabs 30 are folded downwardly with their carrying flap 28, they are properly aligned with their associated locking apertures by the time the carton reaches the latching mechanism.
  • each single carton initially engages the circular tooth portion 136 of one of the two radially extending arm members 132 which do not carry shiftable tucking fingers 138.
  • the shiftable finger positioning member 186 at this point is releasably held by the spring loaded roller 118 in the proper rotational orientation so that the non-finger carrying tooth 136 will be engaged by the carton.
  • the finger positioning member 106 is rotated by the passing carton itself as each circular tooth portion 136 is rotated into the path of the carton to there be picked up by an opening 20 between depending pockets 16 of the carton.
  • the carton itself acts as a driving rack to impart rotational motion to the finger positioning member 106 in the manner of a driven pinion. This insures that the latching mechanism acts in proper timed relationship to the passing carton even though the carton may not be moving at the exact speed of the conveyor belt 36.
  • the next tooth member 136 to be rotated into the carton path is the opposite nonfinger carrying one.
  • the opposite detent 130 allows inward spring urged motion of the roller follower 118 of the detent mechanism to arrest rotation of the finger positioning member 106. This insures proper orientation of this member no matter what the spacing between the trailing end of the carton just past and the leading end of the next carton to be conveyed through the machine.
  • the fingers can be held retracted away from cartons until the tab is practically opposite the rotational center of the finger and can then be inserted in a more nearly perpendicular manner while the carton is traveling through a relatively short distance. This tends to avoid misorientation of the tab which might occur if the finger mere- 1y rotated into-and out of the path of the particular carton disclosed without the out and in camming action.
