A conveyor system (16) pre-inserts a portion of a web (15) into a first belt before the portion is gripped between the first belt and a second belt. In one exemplary embodiment, a pair of lips of a web are inserted into a corresponding first pair of belts (40, 41) and then the pair of lips are secured in the first pair of belts by inserting a second pair of belts (48, 49) into the first pair of belts over the pair of lips. |
