To provide a vertical bottom sticking device which does not generate a measurable diameter-increase of a driver pulley finally leading to the increase of a conveyor belt speed as a result of the contamination of the driver pulley.
Regarding the vertical bottom sticking device for a cross bottom bag formed from a cylindrical part, a bag 1 is made passed through various kinds of processing stations along the sending direction X within the bottom sticking device. A station for making the bottom grooves and a station for sticking are continuously arranged in the bag 1 sending direction. There are a novelty and inventiveness in the aspect of the device's limiting the contamination of the driver pulley 4. The limitation is realized by arranging a couple of the driver pulleys 4 ahead of the bottom-grooves making station in the sending direction X of the cylindrical part 1.
