A combination of a self-opening shopping bag and a coupon packet is disclosed together with apparatus and a method for making same. A flat coupon packet containing coupons is affixed to the front panel of the bag. The coupon packet is sized and positioned widthwise between the side gussets of the bag and spaced apart from the bottom of the bag so that, when the bag is folded flat, only the front and rear panels of the bag underlie the packet. The coupon-applying apparatus is designed and positioned to apply coupons at the beginning of the bag-making procedure. It includes a glue applicator mounted adjacent the former of the bag-making machine for applying a strip of glue to a side of the continuous sheet opposite the forming means, the strip extending lengthwise of the sheet in a predetermined lateral position. A packet feeder is mounted on the former just downstream of the glue applicator for feeding coupon packets lengthwise of the paper flat onto the continuous sheet upon the strip of glue. A mechanical and electrical timing system is operably connected to a rotationally driven element of the bag-making machine for synchronizing therewith the operation of the glue applicator and packet feeder. It is timed to position each packet on the continuous sheet of bag paper at periodic intervals in a predetermined longitudinal location such that the packets neither interfere with nor are removed by subsequent steps in the bag-making procedure.

Method for applying coupon packets to paper bags

A combination of a self-opening shopping bag and a coupon strip is disclosed together with apparatus and a method for making same. An elongated coupon strip containing coupons is affixed inside the front panel of the bag. The coupon packet is sized and positioned widthwise between the side gussets of the bag. The strip has a perforated margin portion and only the margin is adhered to the bag so that the coupons can be readily detached. The coupon-applying apparatus includes a coupon strip roll stand positioned in line with the bag paper roll stand. A glue applicator is mounted on the coupon strip roll stand for applying glue to the margin of the strip. The coupon strip meets the underside of the bag paper as the paper travels around an outfeed roller of the bag paper roll stand. The coupon roll stand includes a brake for tensioning the strip. Spacers are mounted on the former and spaced apart for the coupon strip to pass between them. The bag paper is formed into a tube enclosing the strip and protecting it during subsequent steps in the bag-making process. A metering pump is operably connected to a rotationally driven element of the bag-making machine for proportioning the discharge of glue from the glue applicator to the rate of bag production.
