ワークｌＯを並べる必要がなくなる。In other words, unlike the conventional chuck type, there is no need to line up the workpieces 10 at intervals.
なお、ノズル本体１ｌを多数設けることにより、多数の
ワーク１０を同時に保持・搬送することもできる。Note that by providing a large number of nozzle bodies 1l, a large number of works 10 can be held and transported simultaneously.
また、ワーク１０の保持は、膨らんだゴム製チューブｌ
２で行なうから、ワークｌＯの穴１０ａの内周面に傷が
つかず、ワーク１０の保持も確実である。In addition, the workpiece 10 is held by a swollen rubber tube l.
2, the inner peripheral surface of the hole 10a of the workpiece 10 is not damaged and the workpiece 10 can be held securely.
ワークＩＯとして、内径４．６Ｍ、外径１２ｘｘ，高さ
