Abstract
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.
