20200384715 · 2020-12-10 ·

A heat press includes a clutch and a linkage that moves the upper platen relative to the lower platen from a first position to a second position. The distance between the upper and lower platen is less in the second position than in the first position. The clutch is coupled to the linkage and mounted to the upper platen. The clutch is configured to adjust the distance between the upper and lower platens in the second position in response to movement of the upper platen from the first position to the second position being impeded by a work piece positioned between the lower platen and the upper platen.

Thermal transfer printing machine for printing images on articles by means of a heated pad, particularly for printing images in cavities or recesses
10857782 · 2020-12-08 · ·

A thermal transfer printing machine with stationary support elements for supporting an article and a thermal transfer assembly vertically movable above the support elements, between a raised rest position and a lowered working position is disclosed. The machine has a surface heated transfer pad, supply and guide devices, a flexible printing ribbon which carries thermally transferable ink images, a position sensor providing electrical signals indicative of the vertical position of the transfer pad and a control unit with a learning phase, said control unit causes a descent run of the thermal transfer assembly, until the transfer pad engages with an article of a predetermined type. The position sensor detects and stores reference data characterizing descent run and the control unit initiates a subsequent descent run towards an article of the same type, comparing the reference data to the current descent run data, and stopping printing when an anomaly is discovered.

Multi-layer tethers for micro-transfer printing

A micro-device structure comprises a source substrate comprising sacrificial portions laterally spaced apart by anchors. Each sacrificial portion is exposed through an opening. A micro-device is disposed on each sacrificial portion and laterally attached to an anchor by a multi-layer tether. In certain embodiments, a micro-device structure is constructed by providing the source substrate, disposing micro-devices on each sacrificial portion, depositing a first tether layer over at least a portion of the source substrate and the micro-device, depositing a second tether layer over the first tether layer, and patterning the first tether layer and the second tether layer to form (i) a multi-layer tether for each of the micro-devices such that the multi-layer tether laterally attaches the micro-device to one of the anchors, and (ii) an opening exposing each of the sacrificial portions.

Rounded image canvas corners
10828885 · 2020-11-10 · ·

A printing process that reduces the amount of flash that occurs when printing to a surface of a plastic card. The printing can occur by a retransfer printing process. The printing process includes generating an image canvas that has rounded corners instead of the conventional right angle corners. The use of rounded corners on the image canvas reduces the amount of printing in the image canvas at the corners compared to an image canvas that has right angle corners, thereby reducing the amount of printing that is present that could form flash at the corners of the card surface.

FLEXIBLE HEAT TRANSFER DIE COMPRISING A THERMAL INTERFACE MATERIAL

Methods, apparatus and system for decorating plastic articles having an uneven surface or hollow structure are disclosed. An assembly comprising a transfer pad and a flexible heat transfer die comprising a thermal interface material (TIM) replace the hard rubber die in a hot-stamping process to fuse indicia into the surface. The assembly modifies ordinary pad printing into a hot-stamping process that transfers indicia onto uneven surfaces. A pad printing machine or other robotics is used to move the assembly from a position of heating to a position of compressing the ink transfer to the surface of the article.

Method and apparatus for cold-stamping onto three-dimensional objects

A method and an apparatus for cold-stamping onto a three dimensional object. In a first step, an adhesive is applied to the object at a first workstation. In a second step, a transfer film is pressed onto the object by a pressing device at a second workstation. At the same time, the adhesive is cured at the second workstation. As a result, the decorative material of the transfer film adheres to the object at the positions on the object which are provided with adhesive. If, following this, the transfer film is removed from the three-dimensional object after being pressed on, the decorative material remains on the object at the desired positions. At the positions at which in the first step no adhesive has been applied to the object, the decorative material does not adhere to the object but rather remains on the carrier film of the transfer film.
