A continuous motion packaging machine which forms packages from overlying webs advanced along a path at a constant speed. A tooling carriage traverses a repetitive path which includes an “on-line”increment during which the tooling carriage matches web movement and package operations are performed. The tooling carriage is driven by linkage including a power input shaft operated at varying speeds throughout each cycle to maintain carriage position relative to the webs. Two brushless servo motors are used. One drives the webs, the other drives the tooling carriage. A computer program compares relative motor positions at points throughout each cycle to a pre-established position pattern and adjusts motor controller output to maintain one motor position relative to the sensed position of the other motor.
