Patent number: 8931618Abstract: An apparatus and method are provided, for alternatively producing either small or bulk packs of napkins from a stack of folded napkins produced by one folding machine, through use of a pack dispatching arrangement having an inlet, a small pack transfer station and a bulk pack transfer station, and configured for operation in a small pack mode for dispatching a stream of spaced apart small packs of folded sheets separated from the stack of folded sheets, and received at an inlet of the pack dispatching arrangement, to the small pack transfer station, and alternatively operable in a bulk pack mode for dispatching a stream of spaced apart bulk packs of folded sheets separated from the stack of folded sheets, and received at an inlet of the pack dispatching arrangement, to the bulk pack transfer station.Type: GrantFiled: January 31, 2012Date of Patent: January 13, 2015Assignee: C.G.

Patent number: 8882098Abstract: An interfolder separator apparatus and method utilize a pair of count fingers that are movable longitudinally along and transversely to a stream of folded sheets, for temporarily supporting each successive pack formed by the separator and then releasing each successive pack when partly completed to alternating build fingers, so that the operation of separating successive packs from one another is performed separately from the operations of completing the build of each pack and transporting the completed packs to downstream operations. The count fingers may be mounted to pivot about axes that are movable longitudinally along and transversely to the stream of sheets. A first or last panel of the completed pack may also be folded back partly upon itself, after the partly completed pack is released by the count fingers. Some or all of the fingers may be spring loaded and automatically resettable for clearing jams.Type: GrantFiled: September 4, 2012Date of Patent: November 11, 2014Assignee: C.G.

Patent number: 8696537Abstract: A method and apparatus are provided, for forming a stack of interfolded sheets of porous material including a leading panel having a partial-panel width joined along a fold line to a trailing panel having a full-panel width, by controlling the position of leading edges of the sheets both upstream and downstream from the nip between the interfolding rolls of the folding machine with vacuum applied through corresponding vacuum ports disposed in the periphery of the folding rolls at circumferential distances equal to the partial panel length ahead of each gripper and tucker in the direction of rotation. Sufficient suction is applied to hold both the leading edge of the leading panel of a given sheet and an underlying portion of the trailing panel of the immediately preceding sheet against the periphery of one of the other of the rolls downstream from the nip.Type: GrantFiled: February 16, 2010Date of Patent: April 15, 2014Assignee: C.G.

Publication number: 20130296153Abstract: Embodiments of the present invention provide new and improved folding apparatuses and methods for interfolding a continuous stream of sheets into a single-fold interfolded pattern of sheets while passing all of the sheets substantially along a single sheet path. More particularly, all sheets in the continuous stream of sheets pass through the nips between adjacent components.Type: ApplicationFiled: May 1, 2012Publication date: November 7, 2013Applicant: C.G. Bretting Manufacturing Co., Inc.Inventors: James Andrew Walsh, Tad T. Butterworth

Patent number: 8544833Abstract: The invention provides a method and apparatus for separating a stack of folded sheets by inserting a first, second, third and fourth count fingers into four successive openings in the stack, and separating the stack between the second and third count fingers. Where separation is carried out after a desired number of folded sheets have passed the third count finger, a completed pack having the desired number of sheets may be formed downstream from the third count finger. The count fingers may be operatively mounted in count finger cassettes.Type: GrantFiled: September 13, 2012Date of Patent: October 1, 2013Assignee: C.G. Bretting Manufacturing Co., Inc.Inventor: James Andrew Walsh

Publication number: 20130248325Abstract: A system for forming and wrapping a plurality of stacks of sheet like product is provided. The system includes a separator apparatus for converting a stream of spaced apart sets of stacks into a repeating stepped configuration. The system includes a mechanism for merging the stepped configuration of stacks into a single file stream of stacks. The system includes a cutoff apparatus for cutting a plastic sleeve in which the stacks are wrapped. The system includes a turner apparatus for changing the direction of travel of individual units comprising of a stack of product within a length of the sleeve 90 degrees while maintaining the orientation of the units.Type: ApplicationFiled: March 22, 2013Publication date: September 26, 2013Applicant: C.G. Bretting Manufacturing Co., Inc.Inventors: James R. Michler, Timm G. Retzloff, Andrew Kell Balduc, David J. Brauer

Patent number: 8490772Abstract: A log accumulator comprising a plurality of buckets, a feed arrangement and a transport system and methods are provided. The feed arrangement loads logs onto the buckets. The transport system transports the buckets past the feed arrangement for loading of the buckets. The transport system and the feed arrangement are configured to maintain the feed arrangement in a fixed relative position with one of the buckets for an extended period of time while the feed arrangement loads the one of the buckets. The accumulator may include an unload arrangement that operates to unload logs in substantially the same manner as the feed arrangement.Type: GrantFiled: December 28, 2010Date of Patent: July 23, 2013Assignee: C. G. Bretting Manufacturing Co., Inc.Inventors: James R. Michler, Thomas W. Schneider

Publication number: 20130184139Abstract: A movable tucker apparatus and method include a tucker element having a tip and base at opposite ends thereof, a tucker spring and a tucker positioning lug configured for operative mounting within the slot in a folding roll. The lug is operatively affixed to the roll within the slot and extends at least partly across a width of the slot. The tucker element includes a relief for operative receipt therein of the lug. The tucker element, lug and spring are operatively connected to allow the tucker element to move in and out within the slot, and the tip of the tucker to move circumferentially with respect to the slot when the tucker element is operatively mounted in the slot and the tucker positioning lug operatively disposed within the relief in the tucker element.Type: ApplicationFiled: January 13, 2012Publication date: July 18, 2013Applicant: C.G.

Publication number: 20130043268Abstract: A folded product and packaging arrangement utilizes quarter folded and interfolded sheets forming a more-or-less square or cube shaped stack/clip of interfolded sheets closely matching the inside profile of a substantially cube-shaped package, substantially completely filling the package, and allows the same number of sheets provided by former packaging arrangements, which used rectangular sheets folded into U-shaped clips, in a package with a substantially square footprint and having only half the height of the previous packages. Alternatively, the new folding arrangement allows twice as many sheets to be provided in the same size package used in prior approaches requiring U-shaped folded clips of rectangular sheets. Stacked packages inside of a cover may be repositioned when an upper package is expended to present tissue from a fresh box through the top of the cover.Type: ApplicationFiled: August 15, 2012Publication date: February 21, 2013Applicant: C.G.
