Abstract: The present disclosure relates to adjusting and maintaining a position of a cutting surface used to create lines of weakness for rolled products.

Abstract: A pressing roller is provided including an inner core and a roller cover structure where the roller cover structure is divided into segments. Each roller cover segment may have a rigid inner ring, an elastomeric outer ring, and a deformable coupling structure located between the inner ring and the outer ring. The deformable coupling structure may be formed from a shape memory alloy, a carbon fiber composite, or nylon.

Abstract: The present disclosure relates to apparatuses and methods for adjusting and maintaining a position of cutting surfaces used to create lines of weakness in rolled products. During cutting operations, intermittent contact between cutting surfaces causes cutting components to become heated, which in turn, causes an overlap distance between cutting surfaces to vary from desired values. Conversely, when cutting operations are stopped, the components cool, which in turn, may cause the overlap distance to vary from desired values at steady state operating conditions. To help reduce or eliminate the changes to overlap distances caused by cyclical heating and cooling between times of cutting operations and shutdowns, one or more heaters may be utilized to apply heat to one or more components to maintain relatively constant temperatures during periods of cutting operations and/or when cutting operations are paused or stopped.

Abstract: The present disclosure relates to adjusting and maintaining a position of a cutting surface used to create lines of weakness for rolled products. A perforating apparatus includes a housing rotatably supported by a frame, wherein the housing is adapted to rotate about a first axis. A support member including a first cutting surface is rotatably supported by the housing, wherein the support member is adapted to rotate about a second axis offset from the first axis. A roll including a second cutting surface is positioned adjacent the support member, wherein the roll is adapted to rotate about a third axis. The second cutting surface is adapted to contact the first cutting surface as the roll rotates about the third axis. The perforating apparatus is configured such that the functions of adjusting the position of the first cutting surface and holding the first cutting surface in a fixed position are separate.

Abstract: A method for removing dust-carrying air from a moving paper web is disclosed. The method includes the steps of: providing a moving web, the web having a first side and a second side, the web moving at a sufficient rate to produce a boundary layer of adjacent dust-carrying air; providing a NACA duct, the NACA duct having an intake opening and walls that diverge in increasing cross-sectional area to an exhaust opening having greater cross sectional area than the intake opening; and submerging the intake opening into the boundary layer to scavenge dust-carrying air from the boundary layer.

Abstract: An apparatus for removing particulate-carrying air from a moving web. The moving web has a first side and a second side. The apparatus includes a NACA duct positioned in a non-contacting relationship on a first side of the moving web, and at least partially submerged in a particulate-carrying boundary layer of the moving web. The NACA duct can have an intake opening and an exhaust opening such that when the intake opening is submerged in the boundary layer at least a portion of the particulate-carrying air from the boundary layer enters the intake opening and exits the exhaust opening, thereby scavenging particulate-carrying air from said boundary layer.

Abstract: A theoretical based winding process and control for a surface winding machine that can provide the capability to wind products with a desired wind profile, uniform sheet compression, improved compressibility, winding stability, and ease of operator control adjustment, is disclosed herein. The theoretical based surface winding process utilizes the principle of winding a log with a desired wind profile by controlling the surface speed of at least one roller of the surface winding machine.
