The present disclosure discloses a method for improving fatigue strength of a workpiece (100). The method comprises positioning the workpiece (100) in a punch and die assembly (102). Operating the punch and die assembly (102) one or more times to imprint surface features (2) on a portion of a surface of the workpiece (100), wherein the surface features (2) induces compressive residual stresses at a sub-surface level of the workpiece (100), and improves the fatigue strength of the workpiece (100).

A method of marking indicia on tab stock used to provide tabs for use with can ends. The method comprises providing the tab stock to a tab press comprising a punch and a die. The punch comprises a set of raised features and the die comprises a respective set of recessed features such that the features cooperate to deboss said indicia on regions of the tab stock within tab forming areas that face outwardly when the tabs are attached to a tab end. The features are such that, when the press is fully closed, the spacing between at least part of each of the raised features and at least part of each of the respective recessed features is less than the thickness of the tab stock in said regions within tab forming areas.

A transport device and a method for producing a coin with use of the transport device. The transport device is used to transport blanks to a minting station. A drivable first transport part having a plurality of first transport pockets is provided. A first clearance exists between the outer contour of the blank and the inner contour of the first transport pocket. The transport device has a second transport part having a plurality of second transport pockets. A second clearance is provided between the outer contour of the blank and the inner contour of the second transport pocket. The second clearance is larger than the first clearance. The blanks are transferred at a transfer location from a particular first transport pocket into a second transport pocket. The blanks are transported in the second transport pocket to the minting station, and a coin is minted there from the blank.

The present invention is directed to a method for the production of panels from a board. Said panels are produced from the board by dissecting the board along predefined lines. The board comprises a core material board and is laminated with a laminate material layer. At least one impressed region running linear over the complete surface is present in the surface where the laminate material layer is present. The dissecting of the board is accomplished along these impressed regions. After dissecting pairing mechanical locking means at opposite edges of the raw boards are milled out. According to the present invention, the impressed region has a well defined width in order to allow deviations from an ideal dissecting plane, when dissecting the board in order to produce panels. The present invention furthermore relates to a press plate, allowing for the production of boards having well defined impressed regions. Furthermore, the present invention discloses a method for the production of a board, having a specific defined impressed region. In addition, also a board for the production of panels is described.

An outer ring (29) is first transported to an insertion point (E) in the feed device (34). At the same time, a circular blank ring (30) is brought into a starting position (P) in the feed device. The circular blank ring (29) is first aligned coaxially with respect to an axis (A) using a centering body (61). The circular blank ring moves solely radially with respect to the axis (A). The circular blank ring (30) is then inserted into the hole of the outer ring (29). During this movement, the circular blank ring is aligned coaxially with respect to the axis (A) preferably using a centering channel (54). The circular blank ring (30) carries out a superimposed movement in the axial direction (V) and in the radial direction radially with respect to the axis (A).

A stamp device includes a main body. The main body includes a bottom plate on which a carrier and a stamp are placed, a pressing plate which cooperates with the bottom plate to press the carrier and the stamp, a limiting structure for limiting a lateral relative movement of the pressing plate and the bottom plate, and a connecting structure for folding and unfolding the main body. An upper surface of the bottom plate is provided with a working space for placing the carrier and the stamp. The present invention uses the pressing plate and the bottom plate to press the stamp and the carrier for stamping the pattern on the carrier. A movement space cooperates with a limiting member to limit the lateral movement of the pressing plate.

A textured release sheet includes a substrate, which has been electron beam treated, including a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an radiation curable material applied to the bottom side of the substrate. The coating is an UV curable acrylate mixture applied to the substrate, wherein the UV curable acrylate mixture is irradiated with UV-radiation via an excimer laser emitter to produce a UV-irradiated layer wherein the UV curable acrylate mixture is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

A method for embossing a nanostructure, formed on a nanostructure punch, into a punch surface of a curable material which has been applied to a substrate. The method includes the following steps, especially following sequence: alignment of the nanostructure relative to the punch surface, embossing of the punch surface by a) prestressing of the nanostructure punch by deformation of the nanostructure punch and/or prestressing of the substrate by deformation of the substrate, b) making contact of a partial area of the punch surface with the nanostructure punch and c) automatic contacting of the remaining surface at least partially, especially predominantly, by the prestressing of the nanostructure punch and/or the prestressing of the substrate.

A craftwork accessory may provide a portable and/or easy-to-use tool to help users accurately and repeatedly apply stamp impressions and the like to items such as cardstock. The accessory may include a base portion, one or more elevated side portions and cover portion. The side portions mays define a workspace for arranging the item. The cover portion may be movably attached to the base portion or a side portion, for example, by one or more hinges. In operation, the item and stamp may be aligned in the workspace and the cover portion may be pressed onto the stamp to stick the stamp to the cover portion. The cover may then be opened, the stamp may be inked, and the cover portion may be closed and pressed onto the item to stamp the item. The accessory may include alignment indicia on the base portion, side portions and/or cover portion to facilitate placement of the item and/or stamp. The accessory may also include fastening mechanisms, such as magnetic elements, to facilitate placement of the item and/or stamp.
