Abstract
An indexer system for a plastic pipe butt-fusion machine of the type having a machine super-structure, parallel horizontal support shafts affixed to the super-structure, a first clamp system for removably grasping an end portion of a first length of plastic pipe, a second clamp system for removably grasping an end portion of a second length of plastic pipe and an actuator system for moving the plastic pipes toward and away from each other, the indexing system having an indexer shaft mounted on the super-structure spaced from and parallel to the support shafts, an indexer carriage slidable on the indexer shaft, a facer and a heater pivotally secured to the indexer carriage, a translation mechanism for laterally positioning the indexer carriage to thereby locate the facer and heater between lengths of plastic pipe and a structural beam secured to the super-structure and parallel to the indexer shaft, the indexer carriage being slidably secured to the structural beam so that it is retained in predetermined orientation relative to the horizontal support shafts.
