  • Patent number: 11284626
    Abstract: A crimping and cutting assembly includes a first roller engaged with a second roller including a honeycomb pattern of polygonal crimping and cutting members. Various transversely spaced, internally filled dough ropes are fed between the first and second rollers, causing each rope to be continuously crimped and cut at longitudinally spaced locations to create multi-sided food products, specifically polygonal food products having two to six crimped and cut sides. The ropes can permissibly shift or wander laterally during production, resulting in slightly different size or shape food products, while the honeycomb pattern acts to re-align the ropes so as to be tolerant to the ropes wandering while still preventing puncturing of the ropes which could lead to loss of filling and extended production downtime.

  • Patent number: 9579835
    Abstract: A mold tool has a first mold part with a first side forming a first surface, a nozzle exposed on the first side of the first mold part, and a locating ring mounted to the first mold part. The ring has a body of a metal material and a guard of a material softer than the metal material. The body has a ring shape, a perimeter surface facing radially outward, a central opening concentric with a center axis, a mounting face, and a locating face opposite the mounting face. The guard is connected to the body radially within the perimeter surface and projects axially beyond the locating face. The locating ring surrounds and exposes the nozzle. The locating ring can be mounted to the first mold part. A second mold part can be arranged in proximity to the first mold part and have a locating hole in a second surface. The mold parts can be moved toward one another until the guard contacts the second surface or enters the locating hole.

    Abstract: A calendering roller used to manufacture textured nonwoven fabric including papermaking fibers is disclosed. The calendering roller includes a positive pattern that includes a basic element having a ring shape and a repetition of said basic element along multiple rows and columns substantially overall a peripheral surface of the calendaring roller. The ring defines an apex relatively to a center portion of the ring defining a cavity and a grinded surrounding zone. The ring includes at least one radial channel putting in communication the cavity and the grinded surrounding zone so as to define a discontinuous calendering surface. The repetition is regular except for multiple substantially longitudinally and transversally oriented regions. The regions are of limited size with respect to a calendering roller size and randomly distributed so as to define multiple random longitudinal and transverse lines in the textured nonwoven fabric including papermaking fibers, generating a cloth-like visual texture.

    Abstract: This invention provides a mandrel used to produce belts where materials are cured onto a belt. Specific examples for illustration purposes are directed to a mandrel used to produce fuser belts for use in electrophotographic marking systems. The mandrel provides for reduced heating temperature during the curing heating step because the only mass required to be heated during curing is the belt and not the prior art solid mandrel. This provides significant advantages, such as faster cycle time, less energy, and less degrading of layer materials. The present mandrel comprises two terminal caps connected by threaded rods around which the belt is positioned for coating and curing.

  • Patent number: 8157558
    Abstract: An apparatus and method for forming a clay slab includes a frame, a front panel supported on the frame and a rear panel supported on the frame. An outer cable is attached to the rear panel at one end and to the rear panel and to the front panel at another end. A rotatable drive axle is configured to simultaneously wind and unwind the outer cable and thereby move the front panel and the rear panel from an initial position to an intermediate position to draw a block of prepared clay into a gap defined by the front panel and the rear panel. The drive axle is further configured to simultaneously wind and unwind the outer cable in the opposite direction and thereby move the front panel and the rear panel from the intermediate position back to the initial position to remove the clay slab from the slab roller.

  • Publication number: 20120064188
    Abstract: Durable seamless replication tools are disclosed for replication of seamless relief patterns in desired media, for example in optical recording or data storage media. Methods of making such durable replication tools are disclosed, including preparing a recording substrate on the inner surface of a support cylinder, recording and developing a relief pattern in the substrate, creating a durable negative relief replica of the pattern, extracting the resulting durable tool sleeve from a processing cell, and mounting the tool sleeve on a mounting fixture. Apparatus are disclosed for fabricating such seamless replication tools, including systems for recording a desired relief pattern on a photosensitive layer on an inner surface of a support cylinder. Also disclosed are electrodeposition cells for forming a durable tool sleeve having a desired relief pattern. The replication tool relief features may have critical dimensions down to the micron and nanometer regime.

  • Patent number: 8070468
    Abstract: A sheet film forming roll includes a center rotary shaft. Fixed end plates are disposed in two locations which are away from each other in an axial direction of the center rotary shaft, respectively. An external cylinder is made of a metal thin film. Two ends of the external cylinder are rotatably supported by the fixed end plates, respectively. Multiple rolling rubber rolls have ends which are rotatably supported by the respective fixed end plates. The rolling rubber rolls are in sliding contact with an outer peripheral surface of the center rotary shaft, and in sliding contact with an inner peripheral surface of the external cylinder. The rolling rubber rolls divide an annular space between the external cylinder and the center rotary shaft into multiple heating medium chambers arranged in a circumferential direction of the sheet film forming roll. A heating medium is configured to be filled in each of the multiple heating medium chambers.

  • Publication number: 20100263315
    Abstract: A molded siding member having a plurality of longitudinal support portions extending substantially the entire length of the member contained therein, each support portion presenting a cross-section generally shaped like that of an I-beam. The support portions, which are parallel and adjacent to each other, are integrally formed with the siding member from cementitious slurry, including gypsum cement and a latex/water mixture, or hydraulic cement. An amount of the slurry is added to a mold in which longitudinally-oriented core elements are provided that displace cementitious slurry between and define adjacent support portions. After sufficient curing, the siding member is removed from the mold and is ready for immediate use and/or further processing. Alternatively, a continuous method is also provided for producing relatively long lengths of the siding that can be cut to an appropriate size, without the need to produce individual siding members of limited size.
