INPUT CONTROL FOR ROTARY SEALING TURRET

摘要

A method and apparatus for regulating the throughput of a rotary turret heat-sealing machine, without changing the rotational speed of the rotary turret (332). An indexing clutch (324) is controlled to feed cans (320) into the rotary turret such that only a predetermined number of sealing heads are used to seal cans fed therein. The predetermined number of cans is calculated based on a desired throughput rate. Dwell times, temperatures, and pressures can remain constant while varying radically the can throughput.
