Claim:
1. A film roll/bags-on-a-roll making machine, comprising: a feeding unit comprising a first sheet-transfer cylinder, a second sheet-transfer cylinder and a feeding unit power drive, said feeding unit power drive being controllable to rotate said second sheet-transfer cylinder in reversing said first sheet-transfer cylinder for transferring a film/sheet of bags through a gap between said first sheet-transfer cylinder and said second sheet-transfer cylinder; a reel displacement unit disposed adjacent to said feeding unit, said reel displacement unit comprising a rotating shaft, a plurality of discs, a plurality of reel-holding devices, at least one reel-supplying rack and a reel displacement unit power drive, said discs being fixedly mounted on said rotating shaft and spaced along the length of said rotating shaft, said reel-holding devices being equiangularly mounted between two said discs for cycling through a reel let-off position, a reel-supplying position, a film-rolling position and a film-cutting position upon rotation of said discs with said rotating shaft, each said reel-holding device comprising a first reel-holding member mounted at one said disc and a second reel-holding member movably mounted at another said disc to face toward said first reel-holding member for detachably holding a reel between said first reel-holding member and said second reel-holding member, said at least one reel-supplying rack being adapted to receive a reel and to provide the received said reel to one said reel-holding device in said reel-supplying position in such a manner that when one said reel-holding device is cycled to said film-rolling position, said first sheet-transfer cylinder of said feeding unit is attached to said reel in said reel-holding device that reaches said reel-supplying position, allowing said reel to roll up said film/sheet of bags from said feeding unit, said reel displacement unit power drive being controllable to rotate said rotating shaft and said discs in cycling each loaded said reel through said reel let-off position, said reel-supplying position, said film-rolling position and said film-cutting position; a cutting device disposed adjacent to said reel displacement unit and adapted for cutting off said feeding film/sheet of bags from one said reel that is cycled with the respective said reel-holding device to said film-cutting position; and a control unit electrically coupled with said feeding unit, said reel displacement unit and said cutting device, and adapted for controlling the movement of said reel-holding devices of said reel displacement unit to cycle each said reel through said reel let-off position, said reel-supplying position, said film-rolling position and said film-cutting position.
