Abstract: Systems and methods are disclosed herein for designing and proposing an installation of a project for a structure or site that can be based on identifying installation surface faces, installation surface face insolation, obstructions affecting insolation (or similar property), obstacles and penetrations affecting placement of installation equipment, etc., and for providing an educational experience for a potential purchaser of the system comprising general information and at least one structure-specific installation proposal. A selected plan can be implemented from within a proposal platform of the disclosed systems and methods.

Abstract: A bag inserter machine having pinch rolls for automatically unwinding a perforated bag roll one bag length, bag opening and separating assemblies to cooperatively grippingly engage the leading bag of the bag roll and separating it therefrom along perforations and then opening the bag, an inserter assembly movable into the opened bag for moving the opened bag into a case on a conveyer and cuff the upper portion of the bag over the upwardly extending case top flaps, and controls to stop a case on a conveyer in a position to have a bag inserted therein, stop the drive to the pinch rolls after unwinding the bag roll a bag length, then the bag opening and separating assemblies to grippingly engage the bag to separate it from the bag roll, then open the bag, thereafter operate the inserter assembly to insert and cuff the bag and retract the inserter assembly and then allow the conveyer to move another case to have a bag inserted therein, and automatically continue the cycle of operation.
