Abstract
In order to selectively reinforce portions of a material web, a cutting and laminating device efficiently produces the required reinforcing strips and then laminates them to the web. In order to efficiently and accurately produce these reinforcing strips, a cross web shear is utilized which is capable of cutting required reinforcing strips from the fairly large web of reinforcing material in an accurate manner. Once cut, a holding and positioning device is capable of grabbing onto the reinforcing strip and appropriately positioning it next to the primary material web. A separate laminator can then attach this reinforcing strip to the web at a desired location.
Claims33
A laminating device for providing a reinforced region of material supply web, comprising:
- a primary feeding mechanism cooperating with a primary supply web for advancing a predetermined length of the primary supply web;
- a secondary feeding mechanism for advancing a selectable predetermined length of secondary web;
- a cross web shearing apparatus positioned downstream from the secondary feeding mechanism for receiving the predetermined length of the secondary web, the cross web shearing apparatus including a shear blade positioned substantially perpendicular to the secondary material web and movable through a cutting motion to cause a reinforcing strip to be sheared from the secondary web;
- a handling drive positioned adjacent the shearing apparatus for receiving the reinforcing strip from the shearing apparatus and moving the reinforcing strip to a sealing location adjacent the primary supply web;
- and
- a laminating device located proximate to the handling drive for sealing the reinforcing strip to the primary supply web.
An apparatus for producing a supply of material in a web format having reinforcements in predetermined locations, comprising:
- a primary supply feed roller coupled to a primary web to move the primary web in a predetermined manner;
- a secondary supply feed roller coupled to a secondary web to move the secondary web in a selectable predetermined manner;
- a cross web shear device having a shear blade and a support blade, the cross web shear device positioned to receive the secondary supply web at a cutting position between the shear blade and the support blade, the cross web shear further having a blade actuator for moving the shear blade through a cutting motion after the secondary supply web has been positioned at the cutting position resulting in a reinforcing strip to be sheared from the secondary web;
- a movable applicator having an applicator manifold positionable in a cutting position adjacent the cross web shear such that the secondary web extends adjacent a holding surface of the applicator manifold when the secondary web is in the cutting position, the applicator manifold having a plurality of vacuum apertures in the holding surface to create a vacuum seal between the secondary web and the holding surface when the secondary web is in the cutting position, the movable applicator movable between cutting position and a delivery position allowing movement of the reinforcing strip to an attachment location;
- and
- an attachment device positioned adjacent the primary web and adjacent the applicator delivery position, wherein the reinforcing strip can be attached to the primary web at a reinforcing location by the attachment device cooperating with the applicator.
A laminating device for providing a reinforced region of material supply web, comprising:
- a primary feeding mechanism cooperating with a primary supply web for advancing a predetermined length of the primary supply web;
- a secondary feeding mechanism for advancing a selectable predetermined length of secondary web;
- a cross web shearing apparatus positioned downstream from the secondary feeding mechanism for receiving the predetermined length of the secondary web, the cross web shearing apparatus including a shear blade positioned substantially perpendicular to the secondary material web and movable through a cutting motion to cause a reinforcing strip to be sheared from the secondary web;
- and
- a laminating device located downstream from the primary supply web for sealing the reinforcing strip to the primary supply web.
