| 20090242684 | CROSS-CUTTING AND ROLL-CHANGEOVER APPARATUS FOR CONTINUOUS - An apparatus for winding a flexible web continuously moving in a longitudinal travel direction as rolls onto sleeves has a winding station for holding a sleeve and rotating it about an axis for winding the web onto the sleeve. Upstream of the winding station at a changeover station a fresh sleeve is held adjacent the continuously moving web. A shell juxtaposed with the fresh sleeve in the changeover station forms therewith a gap. A cross-cutter for the web is provided adjacent an end of the gap and can form on the web a trailing end and a leading end so that the trailing end travels to the winding station for winding on the sleeve therein. Air is drawn air into the end of the gap to aspirate the leading end into the gap. This leading end is electrostatically adhered to the fresh sleeve in the changeover station. | 10-01-2009 |
| 20090250544 | Tail Free Transfer Winder - Transferring a moving web from a winding roll to a new core is effected by cutting the web to form a downstream web end portion and an adjacent upstream web end portion; splicing the cut web with a tape; moving the spliced web to a position adjacent to the new core; and adhering the downstream web end portion to the new core with the tape. | 10-08-2009 |

| 20120074255 | WEB WASTE DISPOSAL - A system for disposal of a waste web including: a spindle onto which a roll of web is wound; a cutting station for cutting the web; an ejector for ejecting the roll off the spindle for disposal, to free the spindle to be re-loaded with another roll of web. The invention also relates to a method of forming, and removing, a roll of web material from a rotatable device. | 03-29-2012 |
| 20140374530 | WINDING ASSEMBLY - A winding assembly includes a first supporting member, a pivot shaft, a driving assembly, and a limiting member. The pivot shaft is partly received in the first supporting member. The pivot shaft is configured to support the adhesive tape coil thereon. The adhesive tape coil is configured to be rotatable relative to the first supporting member. The driving assembly includes a secondary shaft. The secondary shaft is partly received in the first supporting member and capable of moving relative to the first supporting member. A first end of the secondary shaft is exterior to the first supporting member and is configured to couple to the hollow rod. The limiting member is spaced a preset distance from the first supporting member and capable of moving relative to the first supporting member. The limiting member and the first supporting member are configured to cooperatively limit the wound adhesive tape. | 12-25-2014 |
| 20150321868 | METHOD AND DEVICE FOR THE PRODUCTION OF A NUMBER OF COILED FOIL ROLLS - A method for the production of a number of coiled foil rolls, wherein the foils are reinforced in their edge region by folding. For coiling foil sections with arbitrary width in a very flexible and efficient manner the invention proposes the steps: a) Supplying of a foil which extends along a total width in a conveying direction to a number of coiling devices; b) cutting of the foil in conveying direction by means of at least one knife so that at least two foil sections are created which extend in conveying direction; c) folding of the edge regions of the foil sections by means of at least one folding device and laying about each other of the folded sections and of the remaining part of the foil section; d) coiling of each foil section on one or more coiling devices, wherein the at least one knife and the at least one folding device are moved simultaneous oscillating back and forth relatively to the coiling devices in a direction transversal to the conveying direction during the coiling of the foil sections on the coiling devices. Furthermore, the invention relates to a device for the production of a number of coiled foil rolls. | 11-12-2015 |

| 20090108121 | Method and apparatus for forming a sheeted roll of material - An apparatus for forming a wound roll of discrete overlapping sheets of web from a supply of continuous web. The web preferably is passed around a nip roller that steers the web onto the surface of a take-up core. A knife assembly including a knife blade extended from a knife holder is driven by a traversing mechanism across the width of the web to cut the wound web on the core into discrete sheets, the extended height of the knife blade being preferably the exact thickness of the web. In transverse cutting by the knife of the web wound on the take-up core, the knife holder travels on the outer surface of the web, thus assuring that the knife blade extends just to the outer surface of the next inner convolution of web, thereby cutting the continuous web into sheets without damaging previously wound web convolutions. | 04-30-2009 |
| 20150076276 | WINDING APPARATUS FOR WINDING A WEB INTO A ROLL - A winding apparatus for winding a web material onto an empty core and into a roll, having a winding drum for guiding the web material supported on a first side, and cutting device for cross-cutting the web material prior to winding of it onto an empty core. The winding apparatus has air nozzles for ejecting compressed air onto the first side of the web material near a free end of the web material. By ejecting a gas, which preferably could be compressed air, onto the free end of the web, the free end is blown towards the empty core which is rotated. When the free end of the web material comes into contact with the rotating empty core, due to the ejected gas/air, the web will easily be “caught” by the rotating empty core, even without tape or adhesive, and a smooth new roll of web material wound. | 03-19-2015 |
