Publication number: 20140061358Abstract: Partial webs are separated in a slitter-winder. The partial webs (WP) are separated by spreading in a spreading device having at least a first, bowed spreader roll (14) fitted at one side of the partial webs (WP) and a second, bowed spreader roll (15) fitted at the opposite side of the partial webs. The partial webs (WP) are guided over the bowed spreader rolls (14, 15) so that the wrap angles (B 14, B15) over the spreader rolls (14, 15) are substantially unequal. The partial webs (WP) are guided to the first spreader roll (14) in a lead-in direction (Dinxy) in the XY-direction and the partial webs are guided from the second spreader roll (15) in a lead-out direction (Doutxy) in the XY-direction such that the lead-in direction (Dinxy) and the lead-out direction are substantially divergent.Type: ApplicationFiled: August 26, 2013Publication date: March 6, 2014Applicant: METSO PAPER, INC.Inventors: Heikki Föhr, Tommi Vuoristo

Patent number: 8663416Abstract: Methods of transferring an image to a substrate are generally provided. A heat transfer material can be partially cut to define a shape with cuts made into the heat transfer material (i.e., into its thickness). The heat transfer material includes a transferable portion overlying a release layer overlying a base sheet such that the cuts are made into the heat transfer material through the transferable portion while leaving the release layer and base sheet uncut. The transferable portion of the heat transfer material can be removed from the base sheet in an area surrounding the shape. Then, the heat transfer material can be positioned adjacent the substrate such that the transferable portion defined by the shape contacts the substrate. Heat and pressure can be applied to the heat transfer material. Thereafter, the base sheet can be removed.Type: GrantFiled: June 9, 2010Date of Patent: March 4, 2014Assignee: Neenah Paper, Inc.Inventors: Russell Dolsey, Frank Kronzer

Publication number: 20130243961Abstract: Methods and kits for treating a fibrous substrate prior to forming an image thereon are provided. The method can include positioning a treatment sheet adjacent to the fibrous substrate, transferring a salt (e.g., calcium chloride, magnesium chloride, or a mixture thereof) from the treatment sheet to the fibrous substrate using a wetting solution (e.g., an aqueous solution, such as water) to carry the salt from the treatment sheet into the fibrous substrate, and drying the fibrous substrate such that the salt remains in the substrate. For example, the transfer of the salt from the treatment sheet into the fibrous substrate can be accomplished via pressing the backside of the treatment sheet such that the wetting solution flows from the treatment sheet into the fibrous substrate while carrying the salt.Type: ApplicationFiled: March 19, 2012Publication date: September 19, 2013Applicant: NEENAH PAPER, INC.Inventors: Russell Dolsey, Melanie K.
