Embodiment Construction
[0034] figure 1 with figure 2 The illustrated intermediate transfer member support system 10 includes two transverse frames 12 and 14, one disposed on each side of an intermediate transfer member 18, and various supports extending transversely between the two frames 12 and 14. , drive and tension roller 16 to limit the intermediate transfer member to follow the closed loop and pass through various parts of the printing system. Further details of the remainder of the printing system and the intermediate transfer member support system are well documented in the prior art and therefore need not be repeated in this context. Basically, in the area indicated by 20, the intermediate transfer member passes under the image forming site, where ink is deposited on the intermediate transfer member to form an image. The intermediate transfer member rotates clockwise as shown to carry the ink image to the area indicated at 22 where the wet image is heated to evaporate the ink carrier and...

Described herein is a printing system having an intermediate transfer member in the form of a seamed endless belt for transferring an ink image from an image forming station where the ink image is deposited on the intermediate transfer member to an embossing station, in The ink image at the embossed site is transferred onto a printed substrate. The strip has a thicker structure along its edges than the strip. The structure is received in the channel to guide the belt and maintain the belt under transverse tension. There are two drive members, each located in a respective one of said channels. The two drive members are connected to move synchronously with each other, and each drive member has a corresponding laterally protruding holder shaped to form a gap with the intermediate transfer member in which the intermediate transfer member is to be formed. Locking engagement of structures on the front end of the strap. Rotation of the drive member during installation of a new intermediate transfer member is used to thread the web through the printing system by pulling the web from its front end.
Description
technical field [0001] The present disclosure relates to a printing system in which droplets of liquid ink are deposited onto a movable intermediate transfer member at an image forming site and transferred from the intermediate transfer member to a printing substrate at an impression site. Specifically, the present disclosure relates to an apparatus for threading an intermediate transfer member through various parts of a printing system. Background technique [0002] The applicant has previously disclosed a printing system and method in which images composed of ink with an aqueous carrier are jetted onto a recirculating intermediate transfer member which transports them to where they are transferred to Embossed site of the desired printed substrate (eg, paper, cardboard, plastic film, etc.). Such systems allow the distance between the surface of the intermediate transfer member and the inkjet printhead to remain constant and reduce wetting of the substrate, as opposed to in...
