Abstract:
1. A gluing method of applying glue, by a contact glue gun, to a gluing area in a gluing margin of a joint flap of a corrugated board sheet transferred on a box production line in a gluing process, the method comprising: applying pressure to the contact glue gun by a first pressure device in a direction that decreases a self-weight of the contact glue gun against the corrugated board sheet during the gluing process; detecting a reaction force of the gluing margin by a reaction-force sensor arranged in the box production line downstream of a slotter creaser and upstream of the contact glue gun in a traveling direction of the corrugated board sheet along the box production line, the gluing margin being compressed in the slotter creaser; and applying pressure against the gluing margin of the corrugated board sheet by a second pressure device arranged in a proximity of a gluing point at which the glue is applied by the contact glue gun during the gluing process, the pressure applied by the second pressure device being set in accordance with the reaction force detected by the reaction-force sensor.
