ABSTRACT:
A machine for blow molding articles, particularly bottles wherein a central, horizontal shaft carries a plurality of radial arms positionable at an equivalent number of work stations arranged in a common vertical plane. The work stations are grouped around the central shaft and are at varying distances from the shaft, and the arms are extensible to reach the stations furthest spaced from the shaft. Fixed actuating means are located adjacent the remote stations and the extensible arms are coupled to the actuating means located at these remote stations. In this way, the extensible actuating means is provided only where needed, the mass and complexity of the rotary arms is reduced and a simple, efficient structure is obtained. The method of the present invention includes the rotation of the shaft in stepwise fashion to align the arms in succession with the work stations and coupling the arm to the fixed actuating means for extension and retraction of the arms at the remote work stations.
