An improved burster for separating continuous form stationery along transverse lines of weakening wherein the infeed and outfeed rollers are maintained a fixed distance apart, with the outfeed rollers being driven at a faster rate of speed than the infeed rollers. A limited lost motion connection is interposed in the drive to the infeed rollers to allow the infeed rollers to establish an idler relationship relative to the outfeed rollers when the stationery strip is gripped between both sets of rollers so that the infeed rollers rotate at a rate of speed which approaches that of the outfeed rollers. When the limit of the lost motion idler relationship is established the speed of the infeed rollers is rapidly reduced, causing severance of the strip of stationery along the transverse line of weakening.
