Abstract
A top sealer for a form, fill and seal packaging machine includes first and second anvils disposed on opposing sides of a processing path of the machine. The anvils are configured to move transverse to the processing path for engaging the top fins of each of the cartons and compressing the fins for forming the carton top seal portion. A first wedge section is mounted to the first anvil and a second wedge section is mounted to the second anvil. The first wedge section includes a raised portion extending from a face of the wedge. The first wedge is mounted to the anvil to contact the raised portion with a first vertical panel/extended gable panel juncture contemporaneous with the anvils engaging the top fins. Contact of the raised portion with the first vertical panel/extended gable panel juncture forms a crease at that juncture. A method for forming a top seal at the fin panels and a crease at the juncture is also disclosed.
