Abstract: In an apparatus for successively making plastic bags, a laser beam irradiator (5) irradiates laser beam (6) onto webs of panel material (2) and a body of zipper material (3) to heat and melt the webs of panel material (2) and the body of zipper material (3) with the laser beam (6). The webs of panel material (2) and the body of zipper material (3) are fed intermittently at a speed V predetermined to be changed by time T. The irradiator (5) is controlled on a feedforward control basis for the laser beam (6) to be regulated in amount Q, the amount Q being calculated from the speed V predetermined, to obtain a calculated value of amount Q. The laser beam (6) is regulated in accordance with the calculated value to heat and melt the webs of panel material (2) and the body of zipper material (3) uniformly irrespective of the speed V being changed.

Abstract: In an apparatus for successively making plastic bags, a laser beam irradiator (5) irradiates laser beam (6) onto webs of panel material (2) and a body of zipper material (3) to heat and melt the webs (2) and the body (3) with the beam (6). The body (3) comprises male and female members (9, 10) including fitted portions and flange portions (11), the fitted portions being fitted with each other. The irradiator (5) irradiates the beam (6) onto the webs (2) and the flange portions (11) on opposite sides of the fitted portions to heat and melt the webs (2) and the flange portions (11) with the beam (6) so that the webs (2) and the flange portions (11) are welded to each other along two welded lines (12) without heating the fitted portions with the beam (6). The irradiator (5) comprises a source of laser beam (13), a ball lens (14) and a glass plate (15), the lens (14) and the plate (15) being interposed between the source (13) and the webs (2) and between the source (13) and the flange portions (11), the plate (15) being V-shaped in section to have a central portion protruding toward the webs (2) and the flange portions (11), the beam (6) being magnified and divided by the lens (14) and the plate (15) so that the webs (2) and the flange portions (11) are welded to each other along two welded lines (12).
