PURPOSE:To prevent a liner from being shifted by sucking dust by effectively blowing up the dust by air blown out from a blow-out port and sucking the dust to be removed by an exhausting port. CONSTITUTION:At the outer peripheral part of a deposit horn head 11, an air supply chamber 22 is provided with an air blow-out port 23 opening downward, and a wall part 26 is provided to cover the downside of the chamber 22. Then, an exhausting chamber 27 is provided as the exhausting port to exhaust air in this cover wall part 26. The chamber 27 is provided in the side direction of a conveyor 108 on the supporting face of a half shell, and a filter 28 and a blower 29 are connected so as to suitably exhaust air by sucking force. Thus, even when air exhaustion is made strong, a liner 9(10) can be prevented from shifting the position by the sucking force. |
