Abstract

A form-fill-seal system includes a tube feeding system, an end seal carriage, and a computing device. The tube feeding system feeds a tube of flexible material at a first velocity. The computing device controls the end seal carriage to cause an increase in a velocity of the end seal carriage to substantially the first velocity, a start of a dwell time of the end seal mechanism on the tube of flexible material while the velocity of the end seal carriage is at substantially the first velocity, and an increase in the velocity of the end seal carriage to a second velocity during the dwell time. The end seal mechanism cuts a package from the tube during the dwell time. The increase in the velocity of the end seal carriage to the second velocity results in an increased distance of the package from the tube.
