A pneumatically or hydraulically operated control apparatus comprising a slide, at least two piston and cylinder assemblies and a lever means. This slide transmits movements from the apparatus, imparted to it by the piston and cylinder assemblies acting on the lever means. This apparatus may be used in conjunction with a machine that has components which require controlled movement. Such a machine is a tire building or shaping machine wherein two shafts require controlled movement in opposite directions. The movements of the slide can be imparted to the shafts by various lever systems, of which the following is a specification. |
