Compared with an existing rolling hot stamping machine, the hot stamping machine does not require manual involvement in feeding and discharging, shortens the time for hot stamping one license plate by two-thirds, and has a high hot stamping efficiency.

A position fine tuning device for a unit-type die cutting & hot stamping machine includes at least two imprinting elements, wherein paper of the imprinting elements is delivered by the gripper installed on the chain. The present invention is characterized in that a positioning element is disposed on an input end of a first unit imprinting element and a positioning element is disposed on an output end of each imprinting element. Two neighboring positioning elements accomplish the positioning between the two positioning elements together. By providing the fine tuning elements, the accuracy in the art of die cutting & hot stamping can be assured when the machine is performing a multiple-working-position procedure; whereas, by setting up the reference positioning, it assures that the standards of the front and rear positioning are consistent.

A hot foil stamping press (10) comprises a platen press (16), with a supporting plate (22) comprising a base plate (26) and a compensating plate (28) being rotatably attached to the base plate (26) for switching between an operating position and a makeready position and a hook element (38) comprising a base part and a top part being arranged at an angle relative to the base part. The hook element (38) is rotatably attached to a door (30) of the platen press (16) by a fixation axle for switching between a releasing position and a securing position of the hook element, wherein the top part retains the compensating plate (28) in its makeready position when the hook element (38) is in its securing position.

A device for storing a sheet pile in a converting machine (10) comprises a transfer mechanism (28) for delivering sheets (22) into a piling area (26) of the device (22), and a sampling plate (44) which is adjustable between a sampling position and an access position, wherein the top of the piling area (26) is covered by the sampling plate (44) when the sampling plate (44) is in the sampling position and the top of the piling area (26) is free when the sampling plate (44) is in the access position.

A method of marking a fiber-based product includes providing a heat stamp apparatus including a heating element thermally coupled to a stamping block and a temperature sensor thermally coupled to the stamping block. The system further includes a platen bearing an embossed pattern. Marking is accomplished by heating the stamping element to a predetermined temperature via the heating element and information acquired from the temperature sensor, then bringing the embossed pattern in relation to the surface of the fiber-based product (e.g., via direct contact and compression or simply very close to the surface) to form at least one of a corresponding three-dimensional contour and charred surface region.

A hot foil stamping press with a pressing table (10) on which a sheet can be advanced, a pressing system (20) for pressing a foil (14) onto the sheet, a guiding system (18) for guiding the foil (14) over the sheet, the guiding system (18) defining a foil transportation path which extends across the path along which the sheet is being advanced, a holder (11) for receiving a supply (12) of foil, and a discarding system (22) for the used foil, the holder being arranged at an operator side of the press.

The present invention relates to a blowing means unit and a hot foil stamping and die-cutting device. The blowing means unit fora hot foil stamping device, comprising: a blowing means having a blowing part configured to inject a gas stream to a location of foil material to separate foil and a supporting part for supporting the blowing part; supporting means supporting the blowing means; and lifting means connected to the supporting means for moving the blowing means between a first position and a second position, in the first position, the blowing part of the blowing means is at a working level, and in the second position, the blowing means is at a non-working level to give access to an operation area.

A device for driving a stamping foil over a path through a stamping machine is disclosed herein. The driving device comprises two foil-introduction chain-like elements and a drive member coupled to the foil-introduction chain-like elements for driving the foil-introduction chain-like elements notably through a platen press of a stamping machine. The driving device further comprises at least one first load-measurement device comprising a first detector configured to measure a parameter indicative of the load applied by the drive member for driving the foil-introduction chain-like elements in a first direction, the at least one first load-measurement device being connected to a stamping-machine control unit configured to stop the driving by the drive member when the parameter indicative of the load applied by the drive member and measured by the first detector crosses a threshold.

Hot foil stamping machine stamping a foil onto a substrate, which improves stamping quality under changing conditions, includes a control unit for controlling the temperature of the stamping interface surface to a predefined desired temperature. The control unit receives at least an actual temperature of the heating plate from the at least one temperature sensor and provides a manipulated variable to the at least one heating device. Further, the stamping machine includes a state observer for estimating an actual temperature of the stamping interface surface of the at least one stamping plate based on a physics-based analytical model of the heat transfer between the heating plate and the stamping plate.
