  • Patent number: 6082079
    Abstract: A coupon burster assembly receives a continuous supply of coupons in the form of a web where the forwardmost coupon is attached to the following coupon along a weakened web portion. The burster includes a pair of intermittently rotating feed rollers and a pair of continuously rotating delivery rollers. An activation input receives triggering information from a form-fill-seal packaging machine or from a receiving product sensor. When the activation input receives triggering information, a signal is sent to a clutch-brake to activate the feed rollers. The feed rollers then feed the web into the delivery rollers. When a deactivation sensor located beyond the delivery rollers senses the presence of the forwardmost coupon, a signal is sent to the clutch-brake which stops the rotation of the feed rollers. Because the delivery rollers continue to pull the forwardmost coupon, the two coupons separate along the weakened web portion. The forwardmost coupon can then be delivered to the dispensing location.

  • Patent number: 5966906
    Abstract: A coupon inserter assembly receives a continuous supply of coupons in the form of a web where the forwardmost coupon is attached to the following coupon along a weakened web portion. The inserter assembly includes a pair of intermittently rotating feed rollers and a pair of continuously rotating delivery rollers. An activation sensor is located at a dispensing location or a conveyor carrying receiving products for receiving coupons. When the activation sensor senses a receiving product, a signal is sent to a clutch-brake to activate the feed rollers. The feed rollers then feed the web into the delivery rollers. When a deactivation sensor located beyond the delivery rollers senses the presence of the forwardmost coupon, a signal is sent to the clutch-brake which stops the rotation of the feed rollers. Because the delivery rollers continue to pull the forwardmost coupon, the two coupons separate along the weakened web portion.
