Abstract: With a use of a transfer rotor that has gripping claws on its circumference, spouts are received by the gripping claws and conveyed and transferred to spout holding members of a continuously rotating rotor. The transfer rotor rotates intermittently 60° in a cycle consisting of stopping, acceleration, constant speed, deceleration and stopping. When the transfer rotor is stopped, spouts are received by gripping claws. During the constant rotation, the gripping claws are matched with the speed of the spout holding members, and the gripping claws and the spout holding members run side by side. During this side-by-side running, the spouts are transferred from the gripping claws to the spout holding members. At a transfer position, the gripping claws open, and the spouts move along a guide member as the spout holding members rotate, so that the spouts are pushed into the interiors of holding grooves of the spout holding members.
