Abstract:
A surface winder and method in which a stationary upper winding roll, a lower movable winding roll and a rider roll form a three roll cradle, the lower winding roll being reciprocated to control the position of a partially wound core until the rider roll returns to cradle position after permitting passage of a previously wound log.
Abstract:
Selected products moving along an input path are diverted to one of a plurality of output paths for stacking. A rotating drum is positioned between the input path and the output paths, and a plurality of vacuum pucks are mounted on the drum for transverse sliding movement parallel to the axis of rotation. As the puck moves in an arcuate plane between the input path and the output paths, a cam moves the pucks transversely from alignment with an input path into alignment with one of a plurality of output paths.
Abstract:
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.
Abstract:
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.
Abstract:
Apparatus for producing business forms made up of a plurality of webs including a plurality of towers, one for each web with each web being equipped with a plurality of vertically related modules for imparting characteristics to the webs, each module being adapted to create a characteristic in the web traveling therepast, and means associated with each tower for changing at least one characteristic in the web traveling therepast.
Abstract:
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.
Abstract:
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.
Abstract:
A method of lapping webs wherein two series of web sections are advanced, reversely folding a portion of each section about a transverse line adjacent the section leading edge to lap a portion of the preceding section adjacent the trailing edge, and retarding one series relative to the other.
Abstract:
A method of lapping webs to provide a product suitable for zig-zag folding or rewinding wherein a web is advanced from each of a pair of parent rolls, the web transversely severed into discrete identical sheets which are then lapped no more than one-third the length of each sheet, and thereafter the lapped sheets from each parent roll are combined in staggered reverse relationship whereby all exposed edges face one direction.
Abstract:
Apparatus for making a connected series of stuffed sealed envelope assemblies (conventionally referred to as "mailers") wherein a knife roll serves to control the advance of a return envelope toward a web providing an insert ply after which the knife severs the insert ply web along transverse terminal edges and without intermediate die cut connecting portions to provide the insert ply as fully useable segments (no waste) along with the series of return envelopes for envelopment between continuous webs to provide a series of mailers.
