ABSTRACT:
This relates to a pneumatic feed system for moving a labeler head of a labeling apparatus for depositing labels in mold halves of a blow molding apparatus. The relatively heavy labeler head must be rapidly accelerated and then rapidly decelerated and at the same time moved sufficiently so as to provide for a large number of back and forth cycles per minute. There is provided in association with compressible shock absorbers a pneumatic system including a high pressure supply and a low pressure supply together with throttle valves such that the gas in the unpressurized end of the cylinder is rapidly compressed near the end of the stroke to function as a shock absorber and further, the cylinder is of a much larger diameter than that required for moving the labeler head so as to permit for the rapid acceleration as well as the rapid deceleration.
