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.

A device (1) for sealing a valve (102) bag (100) and corresponding process. The device (1) comprises a sealing clamp (2) movable between an open position allowing the insertion of the valve (102) and a sealing position of the mouth (104) of the valve (102). The device (1) also comprises a foreclamp (8) having first and second foreclamp (8) parts (10, 12). The foreclamp (8) is arranged adjacent the sealing clamp (2) and is movable between an open position allowing the insertion of the valve (102) between the first and second foreclamp (8) parts (10, 12) and a closed position in which the foreclamp (8) holds the mouth (104) of the valve (102). In use, the foreclamp (8) takes up the closed position before the sealing clamp (2) takes up said sealing position. The invention further contemplates a process applying the device (1) of the invention.

The invention provides a laser processing apparatus capable of imparting heat sealing properties to a biaxially stretched polyester film through a method having high efficiency and high safety. The laser processing apparatus includes a laser oscillator, where a film formed of a single layer of a biaxially stretched polyester or a laminate containing a layer of a biaxially stretched polyester on the surface is irradiated with laser light emitted from the laser oscillator, to impart heat sealing properties to a region of the film irradiated with the laser light. The laser processing apparatus may include an optical element which shapes a spot profile of the laser light into a predetermined profile, and may also include a film mounting part which mounts the film.

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).

A first body of fastener material (5) is joined to a first web of panel material (1) while a second body of fastener material (6) is joined to a second web of panel material (2). The first and second bodies of fastener material (5) and (6) are interposed between the first and second webs of panel material (1) and (2) and aligned with each other after the first and second webs of panel material (1) and (2) are superposed with each other. A third body of fastener material (7) is joined to a web of side gusset material (3) to be interposed between the first and second bodies of fastener material (5) and (6) after the first and second webs of panel material (1) and (2) are superposed with each other, the first and second bodies of fastener material (5) and (6) being aligned with the third body of fastener material (7).
