(54) Method of and apparatus for wrapping reams of paper or the like


(57) @ Reams of paper sheets are wrapped in sheets (S) of wrapping material (W) in a wrapping apparatus (100) which is electronically coupled to the sheeter (200) that produces the reams so as to automatically and continuously synchronise their operation. The position of the wrapping apparatus (100) relative to the position of the sheeter (200) is automatically adjusted to ensure synchronisation of the operation of the wrapping apparatus with that of the sheeter. The reams which are randomly received by the wrapping apparatus (100) from the sheeter (200) are monitored and selected reams are delayed (15) to obtain a desired spacing therebetween. The delayed reams are fed to the wrapping section (106) of the wrapping apparatus (100) during predetermined stages of successive cycles of the wrapping section, and the drive (4) for the wrapping apparatus is coupled to the drives for the web positioning and wrapper sheet transfer means (26) for advancing the web (W) and the wrapper sheets (S) to the cutting (104) and draping (104) positions, respectively, at a gradually increasing, constant and gradually decreasing speed conforming to the cycle of the wrapping section.
