A tube marking device includes a delivery unit having operating rollers for delivering a tube. A thermal press printing unit includes a first heating device and a press printing roller which are actuated by a first lift cylinder to move vertically. A first transmission printing sheet is mounted to a first rotary disc, carries a plurality of marks thereon, and is moved by an operating unit. Two adjacent marks are continuous to each other or have a spacing therebetween smaller than 50 cm. A control unit is electrically connected to the delivery unit, the thermal press printing unit, the first rotary disc, and the operating unit. The delivery unit and the operating unit respectively move the tube and the first transmission printing sheet. The thermal press printing unit transmissions the plurality of marks of the first transmission printing sheet onto an outer periphery of the tube.

The object of this invention is to transfer, fix and polish images produced by: toner laser printers or inkjet printers, flexographic technology, silkscreen technology, offset technology, printed on reel support (A), on the plastic or metal surface of three-dimensional objects (16), thanks to which it is possible to detach images from the reel support (A) and subsequently transfer them to the surface of said plastic or metal objects (16) by a thermomechanical (1, 10) action.

A method and a device for clampingly holding against a substrate (8), for example a drinking cup, a heat transfer sheet (5) using a clamping sheet (2), comprising providing a device (1) with a substrate holder (10) for clampingly holding the substrate (8); providing a clamping sheet (2) with a width and a length, length being measured between longitudinal ends of the clamping sheet (2), and wherein at the longitudinal ends of the clamping sheet (2) coupling means (3) are provided; and positioning in catch means (4) of a positioning device the coupling means (3) for keeping the clamping sheet (2) in a first position.

Disclosed is a powder build material handling system for a three-dimensional printer. The system comprises a delivery system. The delivery system is to carry powder build material in a flow of gas from a powder build material supply. The delivery system is to filter the flow of gas to separate the powder build material from the flow of gas. The delivery system is to direct the filtered flow of gas to the powder build material supply to form a closed system.

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.

The invention relates to a method and a device for clampingly holding against a substrate (8), for example a drinking cup, a heat transfer sheet (5) using a clamping sheet (2), the method comprising the steps of:providing a device (1) with a substrate holder (10) for clampingly holding the substrate (8);providing a clamping sheet (2) with a width and a length, said length being measured between longitudinal ends of the clamping sheet (2), and wherein at the longitudinal ends of the clamping sheet (2) coupling means (3) are provided,positioning in catch means (4) of a positioning device the coupling means (3) for keeping the clamping sheet (2) in a first position; especially wherein the method further comprises the steps of:positioning on the clamping sheet (2) a heat transfer sheet (5) wherein a layer comprising a transferrable ink is to be directed towards the substrate (8);positioning against each other the substrate (8) and the heat transfer sheet (5);moving along the substrate the coupling means (3) and at least partially extending the clamping sheet (2); andmoving towards each other the coupling means (3) that are provided at respective ends of. the clamping sheet (2) for clamping the heat transfer sheet (5) in a second position against the substrate (8) wherein the clamping sheet (2) has a substantially maximum extension.
