Means for rotationally driving the turret around a central axis of a cylinder,
The turret has a rotational axis extending in a direction transverse to the advancing direction of the web, and when the turret is rotated, a groove on the surface thereof is previously set to the predetermined length disposed in the groove. Arranged relative to the web to be sequentially fed to a position that provides a cut zipper for attachment to the web;
The device further comprises:
Contour-engaging members that can be engaged with each other, and a zipper previously cut to a predetermined length having a slider mounted on the contour-forming member, are sequentially inserted into the grooves of the turret at a loading position different from the mounting position. Means for supplying;
Means for attaching the zipper of the predetermined length to the web by detaching the zipper cut in advance to the predetermined length from the groove of the turret at the attachment position;
Means for attaching a slider to the zipper such that a slider is attached to each zipper of a predetermined length supplied to the turret.

The apparatus of claim 1 wherein the means for attaching the slider to the zipper comprises a rotating zipper applicator.

The apparatus according to claim 2, wherein a knife for cutting a continuously supplied zipper into a predetermined length is disposed between the slider applicator and the supply position.

4. An apparatus as claimed in any one of the preceding claims, wherein each groove in the turret includes a wide portion for receiving a pre-cut zipper slider.

The device according to claim 4, wherein the wide portion extends from the insertion side end of the groove to a position slightly beyond the center of the groove.

The means for detaching and attaching the zipper having the predetermined length is a heat fusion bar disposed at the attachment position on the opposite side of the turret with respect to the film so as to be able to approach and leave the film. The apparatus according to claim 1, comprising:

The slider mounting means generates a zipper having contour members separated from each other, and the device is disposed between the slider mounting means and the turret and is a means for engaging the zipper contour members And the means includes a pair of rollers, the zipper passes through the nip of the pair of rollers, and the pair of rollers engages the contour forming member of the zipper with each other, and between the two The apparatus according to claim 1, wherein the apparatus is configured to be separated from each other so that the slider can pass therethrough.

The apparatus according to claim 7, wherein a surface of the roller forming the nip is formed in a convex shape.

A bag making machine that receives the web with a zipper attached, molds the web into a bag, fills the bag with the product, and the zipper of the predetermined length forms a reclosable fastener for the bag. 9. Apparatus according to any one of the preceding claims, further comprising a filling and sealing machine.

The machine further comprises a machine for receiving the web with the zipper attached and forming the web into a bag, the bag being subsequently filled with the product, and the zipper of the predetermined length being able to reclose the bag The apparatus according to claim 1, wherein the apparatus forms a simple fastener.

Further comprising means for receiving the web with the zipper attached thereto and forming the web into a roll, the roll web being used later to form an empty bag, or The apparatus according to any one of claims 1 to 8, which is used later in a bag-filling and sealing machine.

In the apparatus for engaging the contour forming member of the slider zipper,
The apparatus includes a pair of rollers, and a nip of the rollers passes through the zipper. The pair of rollers engage the contour forming members of the zipper with each other, and a slider passes between the two. A device that is configured to be separated from each other so that it can.

The apparatus according to claim 12, wherein a surface of the roller forming the nip is formed in a convex shape.

In a method for attaching a zipper previously cut to a predetermined length to a moving web material in a transverse direction at a predetermined interval in the moving direction of the web,
Preparing the web material;
Advancing the web material in a predetermined direction by passing a turret having a surface with a plurality of axially extending grooves that receive the zipper cut in advance to a predetermined length and spaced in the circumferential direction; Including
The rotation axis of the turret extends in a direction transverse to the advancing direction of the web, and when the turret is rotated, a groove on the surface of the turret is previously set to the predetermined length arranged in the groove. Arranged relative to the web to be sequentially fed to a position that provides a cut zipper for attachment to the web;
The method further comprises:
Contour-engaging members that can be engaged with each other, and a zipper that is preliminarily cut to a predetermined length with a slider mounted on the contour-forming members, is sequentially supplied to the groove of the turret at a loading position different from the mounting position. And
Rotating the turret to sequentially advance the zipper of the predetermined length from the receiving position to the mounting position,
Attaching the zipper precut to the predetermined length to the web at the attachment position.

The zipper having a predetermined length is attached to the web at the attachment position by a heat fusion bar disposed on the opposite side of the turret with respect to the film so as to be able to approach and leave the film. Item 15. The method according to Item 14.

16. A method according to claim 14 or 15, wherein the slider is attached to the zipper by a rotating zipper applicator.

The method according to any one of claims 14 to 16, wherein the slider is attached to a continuous zipper, and then the continuous zipper is cut to a predetermined length.
