ABSTRACT:
An improved apparatus for firmly holding a plurality of articles in the form of a bottle or the like on a rotary table has a plurality of supporting mechanisms for supporting the articles with the aid of attractive force generated under reduced pressure. The supporting mechanisms are adapted to rotate about the axis thereof while they revolve round the axis of the apparatus. The respective supporting mechanisms are located at an equal distance along the periphery of a circle on the table. The supporting mechanism comprises a cylindrical support having a flared head and a suction cup fitted in a central cavity of the flared head, the suction cup being in communication with a vacuum source by way of an axially extending through hole in the support. The flared head of the support preferably has a frictional disc fixedly secured to its upper surface and is located flush with the cupping surface of the suction cup. The supporting mechanisms are rotated with the aid of a belt driving system which is arranged outside of the circle along which they are rotatably held. The belt driving system includes two pulleys, an endless belt extended around the pulleys and a tension control pulley, the endless belt being adapted to come in engagement with pulleys fixedly secured to the lower part of the cylindrical supports.
