Apparatus for producing disposable diaper type products such as diapers per se and training pants in which leg elastic strands are captured between a pair of webs which are thereafter united with a fluff pad-equipped web and wherein guide members are employed for traversing the elastic strands to abut leg openings in the diaper type product.

Apparatus and process for making disposable diaper type products

A method and apparatus for applying an elastic waistband to disposable diapers utilizing canted pin-equipped wheels where an elastic patch is applied to the wheels when the wheel peripheries are close together and then stripping the patches from the pins and applying them to a diaper component web when the wheels are further apart.

Apparatus for applying an elastic waistband to a disposable diaper

A method and apparatus for producing raised leg cuffs for diapers in which an elastic band is oriented in a straight line direction so as to be adhesively encapsulated between the fold portions of a diaper web while the same is passing through a folding board.

Method for producing raised leg cuff for diapers including two folding

A method and apparatus for forming fluff pads and the like wherein fluff providing material webs are introduced into separate hammermills and then delivered through a plurality of ducts through a moving screen under vacuum and wherein the ducts are characterized by reverse bends to densify the particle stream at the outside of the curvature for generally perpendicular deposition on the screen.

Method and apparatus for forming fluff pads for diapers and the like

A method and apparatus for forming fluff pads and the like wherein fluff particles are drawn from a hammermill through a plurality of ducts through a moving screen under vacuum and wherein the ducts are characterized by reverse bends to densify the particle stream at the outside of the curvature for generally perpendicular deposition on the screen.

The invention includes a method and apparatus for applying an elastic strand to disposable diapers. It uses canted, spindle-equipped wheels for engaging an elastic strand, moving the elastic strand into a sinuous configuration and stretching the strand. Stripping belts apply the strand to a diaper component.

Method and apparatus for applying leg elastic to an elongated moving web adapted to provide a sequence of diapers wherein adhesive is continuously applied by a first air nozzle and shifted intermittently by means of a second air nozzle angularly related to the first air nozzle.

Method and apparatus for making elastic diapers

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.
