A method and apparatus for operating a diaper-producing machine where a series of unfolded diapers are advanced along a path containing a plurality of stackers each having a folding blade, the apparatus having means for periodically altering the movement of one blade to permit diaper movement past that stacker to a subsequent one, thereby continuing stacking while a previously completed stack is removed.

Method of operating a diaper producing machine and apparatus

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.

Web winding machine

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.

Method and apparatus for manufacturing a product having elastic means

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.

Method of operating a printing press and apparatus

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.

Method and apparatus for developing and handling stacks of web material

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.

Method of diaper manufacture

A method of manufacturing a packaged web product and apparatus therefor wherein superposed webs are compressed and while compressed webs pass through an open-ended forming device having a closed perimeter and simultaneously enveloping the compressed, superposed webs, and thereafter transversely severing the resultant product into identical units.

Method of manufacturing a packaged web product and apparatus therefor

Apparatus for stacking web units involving a transfer mechanism to accumulate substacks when traveling in a vertical path and including L-shaped fingers for supporting the stacks in the vertical path.

Apparatus for stacking product

A method and apparatus for handling articles (such as web stacks) wherein a series of articles is advanced along a first lineal path and gripped therein, thereafter directed about an arcuate quadrant to a second path perpendicular to the first path and while still being gripped, and thereafter translated, while still being gripped, into a third path parallel to the second path, the handling in the first, second, and third paths occurring while a dimension of the article remains parallel to the direction of travel of the first path.

Method and apparatus for handling articles

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.

Method and apparatus for transverse cutting

Apparatus for handling wound rolls wherein an upper takeaway conveyor receives rolls from a source conveyor and delivers the same selectively to a plurality of diverter conveyors. Each conveyor is equipped with a plurality of spaced apart grippers including three fingers grouped two on one side of each roll and one finger on the other.

Apparatus for handling wound rolls

Method and apparatus for handling substacks of business forms to develop balanced stacks for packing wherein alternate substacks are rotated 90.degree. incident to the formation of a stack whereby the glued edges are alternately reversed.
