Patent ID: 7540125

Claim:
A method of inserting an insert into a package, the method comprising: providing a bursting apparatus comprising an infeed powered by a first servo motor and an outfeed powered by a second servo motor, the infeed and outfeed cooperating to define a path for a continuous feed of connected inserts between a source of connected inserts and a point of delivery of an insert into the package, the path including a bursting space between the infeed and the outfeed; energizing the second servo motor to drive the outfeed at a selected speed; energizing the first servo motor to drive the infeed at a feed speed, wherein the speed of the outfeed is selected relative to the feed speed; the infeed advancing a first insert of the connected inserts along the path until the first insert is positioned at least partially within the outfeed and a second insert of the connected inserts, adjacent the first insert, is positioned at least partially within the infeed, so that a first web connecting the first and second inserts is positioned in the bursting space; with the web positioned in the bursting space, the infeed and outfeed supplying sufficient tension on the inserts to burst the web connecting the first and second inserts; and, the outfeed advancing the burst first insert along the path and ejecting the first insert from the inserter, wherein the outfeed is accelerated from the selected speed to a higher speed after the insert is burst from the continuous feed and driven at this higher speed until the burst insert is ejected from the inserter, and once the burst insert is ejected from the inserter, the outfeed is decelerated to the selected speed; when the first insert is ejected from the outfeed, energizing the servo motors to drive the infeed at the feed speed and the outfeed at the selected speed to position a second web between the second insert and a third insert, adjacent the second insert, within the bursting space, with the second insert at least partially within the outfeed and the third insert at least partially within the infeed.
