Abstract
Method of and apparatus for wrapping articles, in particular for wrapping reams of paper in a sheet of wrapping material such as paper or the like. The method comprises coupling the wrapping apparatus to the sheeter which produces the reams so as to automatically, continuously synchronize their operation, automatically adjusting the machine position of the wrapping apparatus relative to the position of the sheeter to ensure synchronization of the wrapping apparatus with the sheeter, monitoring the reams randomly received by the wrapping apparatus from the sheeter and delaying select reams so as to effect desired spacing therebetween, feeding delayed reams to the wrapping means of the wrapping apparatus at predetermined points during the cycle of the wrapping means, coupling the drive of the wrapping apparatus to the drives for the web positioning and wrapper sheet transfer means for precisely advancing the web and wrapper sheets to the cutting and draping positions, respectively, in a gradually accelerating, constant, gradually decelerating manner keyed to the wrapping means' cycle.
