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:
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:
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 method and 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 and apparatus for the transverse cutting of elongated material such as superposed web plies (for example, a convolutely wound log) wherein the material is uniformly advanced along an axial path and a cutting disc blade is moved through an orbit in planetary fashion which intersects the path and is skewed relative thereto while the disc blade is rotating in planes perpendicular to the path.
Abstract:
A method and apparatus for zig-zag folding in which a slotted receiving cage along with separator means are provided for exact count separation.
Abstract:
A sharpening device for an orbital saw involving a pair of circular grinding stones freely journalled in a sub-assembly which in turn is slidably and pivotally mounted on the frame of the saw while being pivotally supported on the member providing the orbital motion for the saw.
Abstract:
An accumulator for logs of wound paper conveys logs between an input end of the accumulator and a discharge end and accommodates speed differences in the log processing equipment at the input and discharge ends. The accumulator includes stationary upper and lower sets of sprockets and movable pairs of sprockets which can move up and down between the upper and lower sets. A continuous conveyor chain extends downwardly from the upper set of sprockets to the lower set at the input end, is festooned between the lower set of sprockets and one of the sprockets of each of the movable pairs, extends upwardly to the upper set of sprockets, and is festooned between the upper set of sprockets and the other sprocket of each of the movable pairs. A plurality of log carriers are mounted on the chain for movement therewith, and logs are fed onto the carriers at the input end as the carriers are moving downwardly between the upper set of sprockets and the lower set. The logs are removed from the carriers at the discharge end as the carriers are moving substantially horizontally between a pair of horizontally spaced sprockets of the lower set.
