Abstract:
A method of transferring a graphene sheet comprising one or more layers of graphene formed on a metal film, such as a copper film, coating a surface of a metal or alloy substrate onto a target substrate. The method includes fixedly contacting the graphene sheet with a contacting surface of the target substrate by applying substantially uniform pressure and heat on a layered assembly. The layered assembly comprises the metal or alloy substrate, the graphene sheet, and the target substrate. At least one layer of graphene of the graphene sheet formed on the copper film coating the surface of the metal or alloy substrate is transferred onto the contacting surface of the target substrate by the substantially uniform pressure and heat, and the at least one layer of graphene forms a graphene film on the contacting surface of the target substrate.

Abstract:
In accordance with some embodiments, a wafer taping device is provided. The wafer taping device includes a tape delivering along a first direction. The wafer taping device also includes a wafer mount unit disposed below the tape. The wafer mount unit has an upper surface for supporting a wafer and having a notch for allowing a cut mark of the wafer to align with it. The notch is staggered with a second direction in the upper surface, and the second direction is substantially perpendicular to the first direction. In addition, the wafer taping device includes a laminating roller disposed above the wafer mount unit and having a long axis elongated in the second direction. The laminating roller is configured to reciprocate along the first direction for pressing the tape to the wafer.
Abstract:
A labelling device includes a linearly displaceable piston operably connectable to a moving mechanism for moving the piston from a resting position to a labelling position. A label carrying mechanism is arranged at the distal end of the piston for carrying an adhesive label and affixing the adhesive label to an object via physical contact at the labelling position of the piston. A force-switching-state system is provided to maintain the piston in relation to the moving mechanism in an attracting force state and the piston moves with the moving mechanism. The physical contact creates an opposite repelling force from the object onto the label carrying mechanism causing separation of the displaceable piston from the moving mechanism. This separation causes a change of the force state of the displaceable piston from an attracting to a repelling force state, causing the linearly displaceable piston to move back to the resting position.
Abstract:
A foil transfer device includes an impression cylinder for transporting a printing substrate, a pressure cylinder for pressing a foil web against the printing substrate on the impression cylinder in a transfer nip jointly formed by the pressure cylinder and the impression cylinder, a blower device blowing into an exit region of the transfer nip, and a deflection element for deflecting the foil web. The deflection element is disposed in such a way that the foil web has a web section freely extending from the pressure cylinder to the deflection element. The blower device is disposed on the same side of the foil web as the impression cylinder.
Abstract:
A system for applying a tin-tie, from a supply of tin-ties releaseably adhered along the length of a liner, with the tin-tie length generally aligned along a length of packaging moving in a first direction includes a tamp applicator for extending and retracting along a second direction substantially transverse to the first direction. The tamp applicator includes a magnet for carrying the tin-tie after it is released from the liner by a peeler, an air assist for aid in releasing and positioning the tin-tie, and a recess and edge for positioning the tin-tie. Part of the tamp applicator carrying the released tin-tie is also moveable in the same first direction, allowing travel in the same first direction as the moving packaging material when putting the tin-tie on the moving packaging material. A spring biases the part to return in a third direction opposite the first direction.

An apparatus having independently rotating shafts for producing discontinuous and continuous side by side bonding using independently rotating bonding units.
Abstract:
A label applicator system provides for high speed, accurate label transfer from a web to items moving on an item transport along a path relative to the system. The items, such as bottles, have a contoured surface. The applicator includes a supply reel for supplying labels on a web and a take-up for taking up the web after transfer of the label. A drive roller moves the web through the applicator system. The system includes a web positioning assembly and a movable label applicator head. A contour sensor senses the bottle contour and develops a profile for the head to follow to apply the labels to the bottles. The supply, take-up and the drive are operably engaged with one another to maintain a relatively constant tension in the web. The web positioning assembly is configured to advance and retract the web to accommodate a pitch difference between the bottles in the bottle transport and the labels on the web and to accommodate movement of the decorating head toward and away from the bottles in the bottle transport.
