Apparatus for interfolding webs, including two clusters of vacuum rolls, each in a generally hexagonal arrangement, each cluster having spaced apart web cutoff means and interfolding means, the vacuum rolls being arranged to develop four equal length paths between the cutoff means and the interfolding means, the apparatus being equipped with vacuum switching means to sequentially change paths of travel of the webs.

Apparatus for interfolding

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.

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 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.

Multiple web unit handling apparatus with cut-off rolls

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.

Web unit handling method and apparatus

A lightweight spring-loaded grinding wheel assembly for mounting adjacent a disc and wherein idling grinders are positioned away from a blade during inactive portions of the cycle, and upon release of an external force, the grinders are urged into co-acting and sharpening relationship with a blade by a flexing support.

Apparatus for sharpening a disc

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.
