With Material Transfer From Press To Press Patents (Class 100/207)
  • Patent number: 10919280
    Abstract: Precision and chip contamination-free placement of two-dimensional (2D) material and van der Waals (VDW) layered materials accelerates both the study of fundamental properties and novel device functionality. The system transfers 2D materials utilizing a combination of a narrow transfer-stamper and viscoelastic and optically transparent film. Precise placement of individual 2D materials results in vanishing cross-contamination to the substrate. The 2D printer results in an aerial cross-contamination improvement of two to three orders of magnitude relative to state-of-the-art transfer methods from a source of average area sub um{circumflex over (?)}2. The transfer-stamper does not physically harm any micro/nanostructures preexisting on the target substrates receiving the 2D material such as, nanoelectronics, waveguides or micro-ring resonators.

  • Patent number: 10884399
    Abstract: Control method for a press installation and installation, where the installation includes a servo press, a conveyor device for conveying pieces from a position of origin to the servo press, and a controller. The controller controls the movements of the conveyor device and of the servo press by means of one and the same master signal, causing a synchronized actuation of both. In the method, the pieces are conveyed to the position of origin and during the travel thereof until reaching the position of origin, the passage of the pieces through a predetermined position of reference before the position of origin is detected, and depending on the detection, the master signal is adjusted for adapting the actuation speed of the servo press.

  • Publication number: 20140352557
    Abstract: An apparatus allows various loose product, such as tire wire, cans, rubber, scrap metal, and the like, to be fed to provide a single, compacted disc output. The apparatus includes a shoot for feeding product where a first hydraulic cylinder can push the fed product into a main tube. A concave pushing surface can help shape the product into a cylinder. A second hydraulic ram can push product as it is gathered and intertwined within the main tube. The second hydraulic ram typically operates orthogonal to the first hydraulic cylinder. The resulting product is intertwined into a disc shape that is generally sufficiently meshed together to prevent the disc from falling apart, easing storage and transport of the product. This is especially useful for product that is difficult to mesh together, such as tire wire, for example.

  • Patent number: 7179349
    Abstract: A web (W) is passed from a preceding treatment stage to a finishing device in which the web (W) is finished in the finishing device and from which finishing device the web (W) is passed further to a subsequent treatment stage. The web (W) is brought to a roll (11; 14) of the finishing device as supported substantially before a nip area (N1; N2). The web (W) is passed from the circumference of a roIl (12; 15) of the finishing device as substantially supported afler the nip area (N1; N2). A device for passing a web in connection with a finishing device of a paper machine causes a web (W) to be brought by the device to the circumference of a roll (11; 14) of the finishing device substantially before a nip area (N1; N2) and/or the web (W) can be passed from the circumference of a roll (12; 15) of the finishing device substantially after the nip area (N1; N2).

    Abstract: To accommodate a press tooling carrier without interference, a control arm straight guide having at least one drive, e.g., having motor angular gears (worm gears), cardan shaft or the like is provided. A control arm straight guide permits a very shallow position of the joints in the completely assembled state. A hydraulic cylinder may be used to support startup of the motor, i.e., to move the control arm straight guide out of its bottom dead center position.

  • Patent number: 6843171
    Abstract: A hydraulic press utilizes a product feed mechanism including a product lifting linkage capable of raising and lowering a product-holding platen while maintaining same in a precise horizontal position during such movement. The hydraulic drive for the lifting and lowering mechanism is capable of moving the platen to any precise vertical position and maintaining same at that position before, during and after press operations. In connection with the lifting and lowering mechanism, a linear motor horizontal drive mechanism is coordinated with the lifting mechanism to enable the product feed system to precisely position the platen anywhere along the travel of the linear motor. The combination of the lifting and lowering mechanism with the linear motor horizontal drive mechanism provides, when operated by an open architecture PC control system, a new and improved product feed mechanism more precisely controllable than heretofore known.

  • Patent number: 6790300
    Abstract: Method and apparatus for registering and bonding upper and lower substrate plates together through a sealer material and in such a way as to form a gap of a predetermined width between the two substrate plates. Registered substrate plates are provisionally pressed to form a joined substrate assembly, which is then pressed under heated conditions at a hot press station, thereby compressing the sealer material into a flattened form and at the same time thermally hardening the sealer material to form a predetermined gap space between the two substrate plates. In order to correct positional deviations which occur to the upper and lower substrate plates in the course of the hot pressing, on the basis detected positional deviations of upper and lower substrate plates of a hot-pressed substrate assembly, upper and lower substrates are set in offset positions instead of aligned positions when registering them at the provisional press station to cancel predicted positional deviations at the hot press station.

  • Publication number: 20020038606
    Abstract: A transfer device combines an advance-return drive mechanism and a clamp-unclamp drive mechanism. The transfer device operates from only one side of a press to position both drive mechanisms above a pair of feed bars thereby greatly reducing spatial constraints and costs and enabling an increase in speed. The feed bars operate to process a work piece along a process direction. The feed bars are cantilevered from the transfer device for easy use with a press, raw materials feeder, and product gatherer.
