A lid (10) for a thermal-transfer printing apparatus comprises a front plate (12) and a pair of primary supports (14), adapted to support respective reels of thermal transfer ribbon, said primary supports (14) being in turn non-rotatably supported by said front plate (12).
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.

Machine for printing images on articles by means of a thermal transfer roller
The printing machine (1) comprises: a supporting structure (11); a thermal transfer assembly (20) movable in a predetermined horizontal direction (21) and comprising a rotatable motorized transfer roller (30) and heating means (70, 71) associated to the transfer roller (30), wherein the transfer roller (30) and the associated heating means (70, 71) are movable vertically towards and away from a path of the articles (A) to be printed; and supply means (2; 12-16, 33-40) arranged to advance a printing ribbon (N) which on a side facing the articles (A) carries at predetermined intervals images formed of a thermally transferable ink. The thermal transfer assembly (20) further comprises first and second deviation rollers (35, 36) whose axes of rotation are horizontal and substantially parallel to one another and to the axis of rotation (x) of the transfer roller (30). The deviation rollers (35, 36) are arranged one upstream and the other downstream of the transfer roller (30) on the path of the printing ribbon (N) and are displaceable vertically towards and away from said path of the articles (A). The printing machine (1) further comprises first and second motor means (43, 44) associated each with a respective deviation roller (35, 36), said first and second motor means (43, 44) being controllable independently of one another, whereby each of the deviation rollers (35, 36) is selectively displaceable vertically independently of the other one.

B41J 2/005 - Typewriters or selective printing mechanisms characterised by the printing or marking process for which they are designed characterised by bringing liquid or particles selectively into contact with a printing material
The machine (1) comprises: a stationary frame structure (2), wherein support elements (8- 12) are provided for supporting an article (A) on which an image (I) is to be printed; a thermal transfer assembly (20) which is vertically movable relative to the frame structure (2), above the support elements (8-12), between a raised rest position and a lowered working position, and includes a transfer pad (21) having an active surface (21a) which is heated in operation; and supply and guide devices (23-36) arranged to advance, along a predetermined path extending in part between the active surface (21a) of the transfer pad (21) and the support elements (8-12), a flexible printing ribbon (N) which on a side thereof carries, at predetermined intervals, images (I) formed of a thermally transferable ink. The machine (1) further comprises a position sensor (80) arranged to provide electrical signals indicative of the vertical position of the transfer pad (21), and a control unit (14) arranged to carry out a learning phase wherein the control unit (14) causes a descent run of the thermal transfer assembly (20), until the transfer pad (21) is brought into engagement with an article (A) of a predetermined type positioned on the support elements (8-12), and through the position sensor (80) detects and then stores reference data characterizing such descent run, and a subsequent printing phase, wherein the control unit (14) causes a subsequent descent run of the thermal transfer assembly (20) towards and up to an article (A) of the same type positioned on the support elements (8-12), detecting and comparing with said reference data the corresponding data that characterize the current descent run, and stopping the printing phase when the comparison between these data is indicative of an anomaly in the current descent run.
