Publication number: 20120190524Abstract: Apparatuses and methods of forming discrete stacks of a plurality of zig-zag folded panels are provided. The apparatus and methods include defining a sheet to form all of the panels of the discrete stack of panels. The sheet may be defined by cutting the sheet from the web prior to folding the web into the interconnected panels for each sheet.

Patent number: 8057375Abstract: An interfolding apparatus and method, utilize, first and second sheet-cutting-and-overlapping arrangements and an interfolding arrangement simultaneously mounted and operatively interconnected in a common frame, for alternatively selectively forming a first or a second interfolded pattern having a given folded width, without replacement of components of the interfolding apparatus. The first interfolded pattern is formed from a first stream of overlapped sheets of a first length cut from a web of sheet material fed along a first path extending through the first sheet-cutting-and-overlapping arrangement to the interfolding arrangement. The second interfolded pattern is formed from a stream of overlapped sheets of a second length cut from the web of sheet material fed along a second path extending through the second sheet-cutting-and-overlapping arrangement to the interfolding arrangement.Type: GrantFiled: May 14, 2010Date of Patent: November 15, 2011Assignee: C.G.

Patent number: 7980504Abstract: A splice is made, between a tail end of first web and a lead end of a second web coiled about an unwind axis, by winding a portion of the first web adjacent the tail end of the first web about a splicing roll mounted for rotation about a splice roll axis oriented substantially parallel to the unwind axis, and then joining the tail end to the lead end by compressing an adhesive between an inside surface of the tail end and an outer surface of the second web. Compression of the adhesive is accomplished by urging the splice roll against the coiled second web while the coiled second web is rotating about the unwind axis in an unwind direction and the splicing roll is rolling about the splice roll axis in a direction opposite to the unwind direction.Type: GrantFiled: April 16, 2010Date of Patent: July 19, 2011Assignee: C.G. Bretting Manufacturing Co., Inc.Inventor: Tad T. Butterworth

Patent number: 7175127Abstract: A rewinder having a first winding roll that transports and supports the web, and a second winding roll located a distance from the first winding roll to define a nip therebetween. The rewinder also include at least one core support plate that is curved for receiving and guiding cores adjacent the first winding roll, a contact finger located adjacent the first winding roll, and a web separation bar adjacent the first winding roll and movable into pressing relationship with the web to press the web against the contact finger to separate the web. In some embodiments, the contact finger is recessed within the first winding roll such that the web separation bar presses the web only against the contact finger to separate the web.Type: GrantFiled: August 26, 2004Date of Patent: February 13, 2007Assignee: C.G.

Patent number: 6877689Abstract: A rewinder having a first winding roll that transports and supports the web, at least one core support plate that is curved for receiving and guiding cores adjacent the first winding roll, and a web separator adjacent the first winding roll and movable into pressing relationship with the web at a velocity at least equal to that of the web. The rewinder of exemplary embodiments winds a web of material a nip defined by the first winding roll, a second winding roll and a rider roll. The web separator of exemplary embodiments comprises a rotatable plurality of fingers that rotates about a common shaft. Because the web separator contacts the web moving at a velocity at least equal to that of the web, the web is effectively separated upstream of the web separator, between the core and the web separator.Type: GrantFiled: September 27, 2002Date of Patent: April 12, 2005Assignee: C.G.

Publication number: 20040206445Abstract: An apparatus and method for applying adhesive in a web converting machine is disclosed. In some embodiments, an adhesive application assembly is used to seal the tail of a rolled product against the rolled product. After being positioned in a location upon a roller, the rolled product is rotated and a sensor detects the location of the tail end, thereby establishing a reference for determining tail length in later operations. When the tail reaches a desired position, the adhesive application assembly applies adhesive to the tail and/or rolled product. In some embodiments, the adhesive assembly includes one or more adhesive sprayers with aperture members, and is self-cleaning. After the adhesive has been applied, the tail is wound upon the rolled product. In some embodiments, an adhesive application assembly is employed to apply adhesive to a core about which sheet material is to be wound.Type: ApplicationFiled: May 12, 2004Publication date: October 21, 2004Applicant: C.G.
