Abstract
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.
Claims12
A method for operating a diaper-producing machine comprising advancing a series of unfolded diapers along a first path, moving a tucker blade for each diaper through said path to fold the diaper and deliver the now-folded diaper to a second path, and selectively displacing the movement of said tucker blade out of said first path, said tucker blade being orbited through said first path.
A method for operating a diaper-producing machine comprising advancing a series of unfolded diapers along a path toward a plurality of stackers in said path, each stacker having a folding blade associated therewith and movable generally perpendicularly to said path and adapted to foldably introduce a diaper into its associated stacker,
- periodically altering the movement of one of said stacker blades to permit continued advancement of a portion of said series past the stacker associated therewith and toward a subsequent stacker while substantially simultaneously therewith, removing a stack of diapers from said one stacker.
A method for operating a diaper-producing machine comprising advancing a series of unfolded diapers along a generally lineal path toward first and second stackers aligned in said path, each stacker having a folding blade associated therewith with each blade being movable generally perpendicularly to said path and adapted to foldably introduce a diaper into its associated stacker,
- altering the movement of the first stacker blade to permit continued advancement of a portion of said series
- removing a multiple diaper stack from said first stacker during said first stacker folding blade movement altering,
- moving said second stacker folding blade relative to said diaper series portion to create a multiple diaper stack in said second stacker, and
- removing a multiple diaper stack from said second stacker during the time said first stacker folding blade is introducing diapers into said first stacker.
The method of claim 10 in which each stacker is indexed in synchronism with the movement of its associated folding blade, incident to introducing a diaper thereinto, and periodically halting the indexing of each stacker to remove a multiple diaper stack therefrom.
Apparatus for operating a diaper producing machine comprising a frame, means on said frame for advancing a series of unfolded diapers along a path toward a plurality of stackers in said path, each stacker having a folding blade associated therewith and movable generally perpendicularly to said path and adapted to foldably introduce a diaper into its associated stacker, and means on said frame for periodically altering the movement of one of said blades to permit continued movement of a portion of said series past the stacker associated therewith and toward a subsequent stacker while substantially simultaneously therewith removing a stack of diapers from said one stacker.
