  • Patent number: 5503712
    Abstract: A flow management system and process for providing controlled separation and sizing of an incoming flow of wood chips. A flow management screen is provided in the form of a horizontal disk screen having a variable speed drive, with the drive controlled based upon the flow rate of wood chips to the screen. By controlling the rotational speed of the disks of the horizontal disk screen, the flow separation and sizing to subsequent screening stations can be predicted and controlled. As a result, more consistent output is provided, as well as improved system efficiency and ability to accommodate for varying operational conditions and wear.

  • Patent number: 5490902
    Abstract: A method and apparatus for embossing paper products, such as paper towels or toilet tissue, in which the tensile strength extending in the machine direction is modified such that after embossing, the tensile strength in the machine direction is more nearly equal to the tensile strength in the cross-machine direction. During embossing, selected portions of the embossed pattern are embossed more deeply to fracture fibers extending in the machine direction, thereby modifying the tensile strength in the machine direction. An improved paper product is thereby formed having a machine direction:cross-machine direction tensile strength ratio which is more closer to 1:1.

  • Patent number: 5489364
    Abstract: A creping system includes a Yankee dryer rotatable about its axis, a blade support mechanism which includes (a) a pair of guide rails, (b) a fixed attitude linear bearing engaging and translatable along each of the guide rails, each fixed attitude linear bearing being mounted on a block and (c) a combination linear-rotary bearing being carried by each block, the axis of each combination linear-rotary bearing being parallel to the generators of the surface of the Yankee dryer and collinear with the axis of the other combination linear-rotary bearing. A stub shaft engages each combination linear-rotary bearing, each stub shaft being translatable along, and rotatable about, the axis of its respective combination linear-rotary bearing. A blade holder is mounted between the stub shafts, and a blade mounted on the blade holder for engagement with the surface of the Yankee dryer.

  • Patent number: 5481171
    Abstract: A motor starter minimizes transient asymmetrical current to an A.C. induction motor during start-up. Desired timing of closing each phase is calculated using the reactance/resistance ratio (X/R) of the motor and calculated capacitive (X.sub.C) and inductive (X.sub.L) reactances and resistances (R) of the motor circuit cable. A target closing angle of the first phase that crosses zero potential of the voltage cycle is determined based on the system X/R ratio, and that phase of the starter is closed individually. After the first phase is closed, the power frequency is used to determine closing of the other phases at 60 degrees intervals corresponding to the X/R-based target timing.

  • Patent number: 5480693
    Abstract: A composite integral sheet of wrap material which includes a first layer of absorbent material containing fibers bearing foraminous hydrophobic water-vapor-permeable pellicles, a second layer of printable material and an impermeable pigmented polymer layer interposed between the first and second layers. Additionally, the absorbent layer will include highly absorbent material formed by in-situ crosslinking of a partially pre-neutralized polyacrylic acid. The composite wrap material has a plurality of air pockets formed between at least one of the first or second layers and the polymer layer, by discontinuously bonding the first or second layers to the polymer material. A method of making the composite integral sheet.

  • Patent number: 5472402
    Abstract: Containers and a method for forming such containers having larger brims with reduced brim curl defects is disclosed including providing a plurality of container blanks for forming containers, forming a plurality of container shells from the plurality of blanks, accumulating the plurality of container shells at an accumulation station, subjecting at least an upper periphery of the shells to a humid atmosphere to precondition the shells with the atmosphere preferably including steam, successively removing the shells from the accumulator and subsequently forming a brim curl about an upper periphery of the shell with the shells being subject to the humid atmosphere for a predetermined time period sufficient to form defect-free brim curls by extending the forming strain limits of the paperboard material. This method being carried out by using an accumulator for accumulating the container shells for further processing.

  • Patent number: 5463843
    Abstract: A system of wrapping and securing together the components of a bulk package including a bottom tray element and a top cap element with an integral web of plastic material. The plastic material, while in a rope-like configuration, is looped about only a single pair of diagonally opposed corners of each of the top cap element and bottom tray element. The tail or terminal end of the web is secured in place by being positioned between a wrap convolution and the bulk package.

  • Patent number: 5460286
    Abstract: A beverage cup lid is disclosed that comprises a circular closure panel, circumscribed by a side wall that terminates in a resilient, restricted diameter edge for capturing a brim of a beverage cup, and a frustro-conical skirt connected around the restricted diameter edge for increasing the hoop strength of the edge, and an extended diameter flange circumscribing the free edge of the skirt for further increasing the hoop strength of the restricted diameter edge such that the edge retains the brim with a force of at least 1 pound. The invention is particularly applicable to beverage cup lids formed by a plastic web machine that applies heat to only those areas that are deformed into structural components on the lid (such as the side wall, restricted diameter edge, and skirt), and which consequently results in some amount of wall thinning in the skirt, and hence some reduction in the hoop strength that the skirt gives to the restricted diameter edge that retains the cup brim.

  • Patent number: 5436057
    Abstract: This invention relates to the discovery that the perceived softness of embossed tissue can be increased greatly while avoiding prior art nesting problems if a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike debossments with deeper more sharply defined signature debossments. The stitchlike debossments are rounded and arranged in wavy flowing intersecting lines. The signature debossments are arranged in regions framed by the intersecting wavy flowing lines.
