Abstract: 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.
Abstract: An embossing method to avoid nesting in convolutely wound rolls and product wherein the repeat length is at least as great as the roll circumference.
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 converting a stream of individual product such as diapers into predetermined count stacks and including a closed chain loop accumulator having differing speed input and output drives.
Abstract: 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.
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 device adapted to be suspended from a crane for lifting and laterally shifting a load including a frame having a fork lift attached thereto for carrying the load and a counterweight means to compensate for the weight of the load and to selectively position the fork lift in a tilted condition.
Abstract: Apparatus for intermediately storing products on a storage device, such as a pallet or the like, comprises an inserter member for feeding products supplied by a conveyor to the storage device. The inserter member is arranged transversely of the conveyor and has a displaceable plunger combined with a planar support surface which is connected to the plunger and which co-operates with a stripper member for returning the intermediately stored products to the conveyor. A discharge member is provided to displace products in storage onto the planar surface support.
Abstract: A core holder for reeling which includes a relatively elongated metal tube and a plastic sleeve fixed on the tube with the sleeve having radially outwardly projecting therefrom a plurality of longitudinally extending ribs, the ribs being grindable to a predetermined radius.
Abstract: A method and apparatus for zig-zag folding in which a slotted receiving cage along with separator means are provided for exact count separation.
Abstract: A method and apparatus for zig-zag folding in which stack lean can be corrected by angularly shifting one gripper-tucker member relative to the other where the gripper anvil tip and the gripper element tip are each a constant distance from the tucker tip during entry of the tucker into the gripper.
Abstract: A core holder for reeling and method of making which includes a relatively elongated plastic tube and a plastic sleeve fixed on the tube with the sleeve having radially outwardly projecting therefrom a plurality of longitudinally extending ribs, the ribs being grindable to a predetermined radius.
Abstract: A sharpening device for an orbital saw involving a pair of circular grinding stones freely journalled in a sub-assembly which in turn is slidably and pivotally mounted on the frame of the saw while being pivotally supported on the member providing the orbital motion for the saw.
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.
Abstract: 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.
Abstract: A method and apparatus for separating a continuous stream of connected business forms into exact count zig-zag folded stacks wherein nip forming rolls are selectively engaged to burst the web stream at a predetermined point and prior to zig-zag folding.
Abstract: 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.
Abstract: A method .[.and apparatus.]. for coating wherein the horizontal flow of coating liquid is restricted adjacent the ends of the coating roll to overcome foaming by high flow rates of liquid flow while avoiding fouling of the roll journals.
