Definitions

• This invention relates to a mass distributable packet which is individualized for a given recipient both as to included inserts and marking for a particular addressee, and the in-line system used to produce such packets.
• Another disadvantage of mass advertising and coupon distribution packets is the inability to determine which individuals responded to the advertising efforts.
• the marking of each individual coupon with a code specifically identifying the addressee which is machine readable, has become very helpful to the advertiser.
• Individuals who did not respond to the advertising can be eliminated from lists to be used in the future, thus reducing substantially the number of pieces required.
• the value of coupons can be adjusted in subsequent mailings to entice use, by consumers.
• the advertiser can target market coupons to nonusers of specific products. Consequently such a capability can be a large factor in reducing the cost of the advertising effort.
• this invention is directed to the producing of a multiple piece solicitation packet which is individualized with respect to both the content and the marking of the insert pieces making up the packet.
• the packet is produced on an in-line basis by use of specialized feed, conveyor, control, marking, and packaging assemblies which make it possible to produce individualized and personalized packets on a large volume basis.
• the insert pieces of each packet are selected for the particular addressee to receive it, and all insert sheets are uniquely-marked to identify the particular recipient.
• the feeder assemblies are compact and, large numbers of them, 150 units or more can be arranged serially to give a wide selection of insert or coupon pieces as few as one (1) but, usually 16 to 44 to a packet, for a given addressee. Further, the feeder assemblies are able to feed coupons on command at a very rapid rate, and to accurately place the coupons on a fast moving conveyor assembly.
• the conveyor assembly holds a number of individual groups of coupons or sheets simultaneously at spaced intervals.
• the individual sheets of each group are accurately held in a fixed shingled position on the conveyor with a small transverse end section of each sheet or coupon exposed to a marking assembly.
• the marking assembly places an identical marking on all the pieces of each group which is distinctive and identifies that particular group with the individual to receive the packet.
• the operation of the conveyor and selective feeder assemblies interact and operate in response to a control assembly which operates on the basis of presupplied data on the addressees and the coupons or insert pieces would be designated for such individual.
• In-line packaging means having simultaneously addressed or pre-addressed wrapper sections makes it possible to group and package individualized coupon or insert groups on an automated, rapid basis.

• the feeder assembly may or may not be activated to deposit an insert on the group. If the coupon group is not to receive the particular insert carried by that feeder, there will be no activation of that feed assembly. This is controlled by the data input material to the computer which has data on coupons to be contained in each unique group for its corresponding addresses. If no insert from that feeder is to be received by that group, the coupon feed unit will not be activated.
