Abstract: Novel methods and apparatus for processing product sales coupons in a self-service environment comprising a coupon processing station which reads indicia from printed coupons and which provides opportunity for selection of electronically stored coupons from memory. Further, the station has multiple booths which may be used separately and which may be used to display advertising when not processing coupons. The coupon processing station dispenses a coupon shopping list having a list of selected coupons and a single machine-readable indicia, such as a bar code, from which all coupons on the list are referenced at the time of purchase. A list insertion hub affixed to an establishment cash register/computer communication system in which the station and hub are used verifies purchases against coupon use rules and validates each coupon which has been redeemed properly. Files of validated coupons are sorted and sent to a central controller for efficacious billing.

Abstract: A method for producing one or more individual stacks of superimposed, secured together, expandable tubular strips forming an expandable honeycomb panel. The strips coated with adhesive are advanced sequentially to the inlet of a stacking chamber having an elevated floor with a longitudinally extending slot of a length to receive each strip and which is narrower than the width of the strips to be delivered thereto. The strip so delivered is pushed up through the narrower slot and against the strip just previously delivered to the chamber, to adhere it to the latter strip. The chamber has a weight bar to exert a downward force on the stack of strips to provide good adherence between the strip.

The strip so delivered is pushed up through the narrower slot and against the strip just previously delivered to the chamber, to adhere it to the latter strip. The chamber has a weight bar to exert a downward force on the stack of strips to provide good adherence between the strip. The improvements are a stacking chamber that has a second pair of wall surfaces that diverge upwardly so that the chamber width gradually increases and adjusting members to progressively adjust the angle of divergence of the second pair of wall surfaces.
