A method comprising: feeding a tube (56, 114, 256, 310, 410) of flexible material at a first velocity through a portion of a form-fill-seal system (10, 100, 210), wherein the form-fill-seal system (10, 100, 210) includes a movable end seal carriage (320, 420) that includes an end seal mechanism (28, 326, 426); increasing a velocity of the end seal carriage (320, 420) to substantially the first velocity; starting a dwell time of the end seal mechanism (28, 326, 426) on the tube (56, 114, 256, 310, 410) of flexible material while the velocity of the end seal carriage (320, 420) is at substantially the first velocity, wherein the end seal mechanism (28, 140, 228, 326, 426) is configured to cut a package (34, 102, 234, 340, 440) from the tube (56, 114, 256, 310, 410) during the dwell time; and increasing the velocity of the end seal carriage (320, 420) from the first velocity to a second velocity during the dwell time, wherein increasing the velocity of the end seal carriage (320, 420) results in an increased distance of the package (34, 102, 234, 340, 440) from the tube (56, 114, 256, 310, 410); wherein the end seal mechanism (28, 140, 228, 326, 426) includes an upper jaw (322, 422) and a lower jaw (324, 432); wherein starting the dwell time comprises extending the upper and lower jaws (322, 422, 324, 424) into an extended position at which the upper and lower jaws (322, 422, 324, 424) contact the tube (56, 114, 256, 310, 410); and wherein the method further comprises ending the dwell time while the velocity of the end seal carriage (320, 420) is greater than the first velocity, wherein ending the dwell time includes retracting the upper and lower jaws (322, 422, 324, 424) from the extended position until the upper and lower jaws (322, 422, 324, 424) are no longer in contact with the package (34, 102, 234, 340, 440). feeding a tube (56, 114, 256, 310, 410) of flexible material at a first velocity through a portion of a form-fill-seal system (10, 100, 210), wherein the form-fill-seal system (10, 100, 210) includes a movable end seal carriage (320, 420) that includes an end seal mechanism (28, 326, 426); increasing a velocity of the end seal carriage (320, 420) to substantially the first velocity; starting a dwell time of the end seal mechanism (28, 326, 426) on the tube (56, 114, 256, 310, 410) of flexible material while the velocity of the end seal carriage (320, 420) is at substantially the first velocity, wherein the end seal mechanism (28, 140, 228, 326, 426) is configured to cut a package (34, 102, 234, 340, 440) from the tube (56, 114, 256, 310, 410) during the dwell time; and increasing the velocity of the end seal carriage (320, 420) from the first velocity to a second velocity during the dwell time, wherein increasing the velocity of the end seal carriage (320, 420) results in an increased distance of the package (34, 102, 234, 340, 440) from the tube (56, 114, 256, 310, 410); wherein the end seal mechanism (28, 140, 228, 326, 426) includes an upper jaw (322, 422) and a lower jaw (324, 432); wherein starting the dwell time comprises extending the upper and lower jaws (322, 422, 324, 424) into an extended position at which the upper and lower jaws (322, 422, 324, 424) contact the tube (56, 114, 256, 310, 410); and wherein the method further comprises ending the dwell time while the velocity of the end seal carriage (320, 420) is greater than the first velocity, wherein ending the dwell time includes retracting the upper and lower jaws (322, 422, 324, 424) from the extended position until the upper and lower jaws (322, 422, 324, 424) are no longer in contact with the package (34, 102, 234, 340, 440).
