Abstract: A packaging machine for loading of individual articles into a product cartons that includes a rotary blank feeder and a rotary board erector. The rotary blank feeder includes a plurality of feeder arms each having a vacuum head. The feeder arms are each rotatable about a common axis of rotation and the entire folding arm assembly is rotatable about an offset secondary axis of rotation. Each vacuum head of the rotary blank feeder moves into contact with the lowermost planar carton blank contained with an overhead hopper and transfers the carton blank to a board feed conveyor. From the board feed conveyor, each carton blank enters into a rotary board erector having a plurality of folding arms rotatable at variable speeds about a common axis of rotation. The folding arms of the rotary board erector partially fold each planar carton blank for loading with individual articles.

Abstract: A water fountain spray modifier for use in combination with a pond aerator to modify the water fountain spray pattern generated by the pond aerator. The water fountain spray modifier includes a support arm pivotally mounted between a pair of brackets mounted to the pond aerator. The support arm includes a spray diffuser formed on its first end and is movable between an operative position and an inoperative position. When the support arm is in the operative position, the spray diffuser is generally aligned with the outlet opening of the pond aerator such that the spray diffuser reduces the height of the water fountain produced by the pond aerator. The water fountain spray modifier includes a locking mechanism that secures the support arm and attached spray diffuser in either the operative position or the inoperative position. The locking mechanism includes a plunger movable between a retracted position and an extended position.

Abstract: A continuous web of material having holes and lines of perforations therein is unwound from a roll and fed onto a staging roller. From there it is pushed onto a carrier belt having pins thereon. The pins match with the holes in the web material, and the web is drawn past a fracturing station which separates sections of the web into sheets along the lines of perforations. The individual sheets then are carried by the belt around an accelerator roll which speeds up the sheets to match the speed of receiving objects with which the individual sheets are to be combined. A second staging roller is installed at the in-feed end of the apparatus and coordinated with the first staging roller, so as to provide continuous and uninterrupted feeding of the web and hence individual sheets to the receiving objects.
