Abstract
PURPOSE: To manufacture a synthetic resin cylinder of the subject continuously and efficiently by winding a band formed by applying synthetic resin on the front and back surfaces and both side ends of a band-shaped spirally in a single layer and without gap and pressing to join the joint of the band.
CONSTITUTION: By passing a band-shaped material 2 made of thick paper, aluminum, etc., through an extruder 6 and forming a synthetic resin layer on the front and back surfaces and both side rims of the band-shaped material 2, a band 9 is manufactured continuously. Next, the end of the band 9 is wound spirally for serveral times without gap around the rotating shafts 8W8a of a spiral winding device 7, and a pressing roller 81 is lowered and slightly pressed against the resin state, the band 9 is wound spirally outside the rotating shaft 8W8a moving towards the tips of the rotating shafts, and at the same time, the neighboring layers of the band 9 are adhered easily, thus obtaining a synthetic resin cylinder 1 of the subject continuously.
