Abstract: A method for producing elastic disposable diapers, apparatus therefor and product therefrom which includes applying a continuous stripe of adhesive to stretched elastic ribbon, V-folding longitudinally spaced portions of the ribbon to immobilize the adhesive in the spaced portion, applying the intermediate flat portions of the stretched ribbon with exposed adhesive to a substrate, to form discreet diapers which have contractable portions therein.

Abstract: A rewinder mandrel, wherein separate adjustment is provided for positioning the core locking lugs and for adjusting the spring tension for pivoting the lugs to uncammed position; and in which novel replacable core lugs are provided, having a bifurcation providing legs facilitating snap-in assembly.

Abstract: A stacking and delivery apparatus for stacks of products such as paper napkins and paper towels includes a magazine into which the products are delivered to form stacks and which supports the stack along a path of product movement. A plurality of fingers are mounted on a conveyor adjacent the magazine, and the conveyor moves a finger into the path of stack movement when a stack is completed and separates the completed stack from the next stack. A drive system for the conveyor moves the conveyor at different speeds during each cycle in which a stack is formed--a first, fast speed at which a finger is quickly moved into the path after a stack is completed, a second, relatively slow speed at which the finger moves the completed stack along the path as the next stack is built up behind the finger, a third, relatively fast speed at which the finger moves the completed stack rapidly along the path, and a fourth speed, which can be zero, during which a completed stack is removed from the conveyor.

Abstract: Apparatus for handling a stream of flat, flexible web products where first and second gripper means are disposed to intersect said stream for tandem operation, and with means operably associated with the first gripping means for deactivating the same after a predetermined number of web products has been gripped.

Abstract: An apparatus for winding a web of sheet material into a roll on a core includes a pair of rollers and a source of vacuum for drawing a vacuum in the space between the rollers. The vacuum holds the core in the space between the rollers. The core is rotated by the rollers, and the web is wound on the rotating core.

Abstract: Apparatus for producing elastic disposable diapers employing an oscillating fork means to V-fold longitudinally spaced portions of an adhesive equipped ribbon on itself to immobilize the adhesive in the spaced portions.

Abstract: An apparatus for transversely cutting logs of web material which are sequentially advanced along a first path and a rotating disc blade is mounted in said apparatus for movement in a second path through said first path from one side of the other of the first path to transversely sever said logs, a sharpener is provided in said apparatus for sharpening said blade. The apparatus is provided with structure for incrementally changing the relationship of said sharpener and said blade to compensate for diameter reduction of said disc blade. The apparatus is equipped with structure for altering the relationship of said paths to also compensate for diameter reduction of said blade.

Abstract: A method for producing elastic disposable diapers, apparatus therefor and product therefrom which includes applying a continuous stripe of adhesive to stretched elastic ribbon, V-folding longitudinally spaced portions of the ribbon to immobilize the adhesive in the spaced portion, applying the intermediate flat portions of the stretched ribbon with exposed adhesive to a substrate, to form discrete diapers which have contractable portions therein.

Abstract: Method and apparatus for applying stretched elastic segments to a web as for a diaper waistband and the like which include advancing a stretched continuous elastic ribbon, gripping the ribbon at two pairs of points, severing the ribbon between the gripped pairs to provide a stretched segment and advancing the ribbon segment in planetary fashion to unite the same to a continuous web.

Abstract: Selected products moving along an input path are diverted to one of a plurality of output paths for stacking. A rotating drum is positioned between the input path and the output paths, and a plurality of vacuum pucks are mounted on the drum for transverse sliding movement parallel to the axis of rotation. As the puck moves in an arcuate plane between the input path and the output paths, a cam moves the pucks transversely from alignment with an input path into alignment with one of a plurality of output paths.

Abstract: A method and apparatus for transverse folding of web segments to provide napkins, hankies, or the like, in which first and second folding rolls are equipped with vacuum ports selectively actuatable to provide a transverse fold, the second folding roll being operated at a surface speed slower than the first.

Abstract: A register assembly including sleeve and collar means and gearing which can be adjusted relative to each other off-machine and to a predetermined position on the plate cylinder journal or shaft so that when the register assembly is mounted on the plate cylinder journal, the plate cylinder not only has exact gear tooth engagement but also proper registration.

Abstract: A method and apparatus for transversely folding diapers which includes advancing a series of unfolded diapers along a horizontal path, orbiting a tucker blade for each diaper through said horizontal path to fold the diaper and deliver the now-folded diaper to a vertical path, and displacing the orbit of the tucker blade upwardly out of the horizontal path whenever a defective diaper appears in the series.

Abstract: This invention relates to a method and apparatus for developing and handling stacks of web material and, more particularly, to such articles as towels (folded or unfolded), tissues, impregnated non-woven sheets and other relatively flimsy webs which are either normally or desirably provided in the form of a rectangular stack.

Abstract: A web unit handling apparatus wherein a plurality of web units are separately advanced along a plurality of delivery paths which are aligned along a lineal collection path, each web unit being transferred into the collection path and thereafter being advanced therein in synchronism with the other web units being transferred into the path.

Abstract: A method of diaper manufacture whereby adhesive is applied directly to the moisture impervious web for attachment thereto of elastic ribbons to make a shirred diaper.

Abstract: A method and apparatus for providing balanced stacks of diapers where a series of diapers are advanced toward a drum equipped with an even number of turning devices adapted for vacuum-actuated engagement of the diapers and cam means are associated with the drum for rotating alternate of the devices 90.degree. to the right and the remainder of the devices 90.degree. to the left so that adjacent diapers in the series are disposed 180.degree. to each other.

Abstract: Method and apparatus for correcting stack lean in a zig-zag folded web wherein a transverse force is cyclically applied to a traveling web so as to vary the motion of the web slightly as it passes through a transverse perforator.

Abstract: Apparatus for producing business forms made up of a plurality of webs including a plurality of towers, one for each web with each web being equipped with a plurality of vertically related modules for imparting characteristics to the webs, each module being adapted to create a characteristic in the web traveling therepast, and means associated with each tower for changing at least one characteristic in the web traveling therepast.
