ABSTRACT:
An apparatus is disclosed for wrapping a moving bundle of newspapers with a wrapping paper on three sides prior to tying the bundle with tying straps. The apparatus includes a section for stacking a bundle of newspapers and a mechanism for dispensing wrapping material at a predetermined feed rate at a location generally in the path of the bundle. Means is provided to grip the wrapping material and to guide the material upwardly so as to cause it to interfere with the path of the bundle and to cause the wrapping material to wrap itself about the bundle and to contact three adjacent surfaces of the bundle. Means is provided to cut the wrapping material when a predetermined length has been dispensed sufficient to contact and cover the three adjacent predetermined surface portions of the bundle. Appropriate pneumatic/electronic circuitry is provided to control the respective speeds and sequences such that each step of the operation is provided in timed sequence. A method of wrapping the bundle of newspaper is also disclosed. Preferably the wrapping material is kraft paper.
