Each print head array has a plurality of print heads, each print head having a respective orientation axis. The plurality of print heads can have at least a first print head and a second print head, wherein the orientation axis of the first print head is angularly offset from the orientation axis of the second print head. The first print head can be offset from the second print head along the substrate movement axis.

MARKING SYSTEMS AND METHODS FOR FIBER-BASED PRODUCTS
20230131528 · 2023-04-27 ·

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.

Flat foil printing press having foil web and sheet guidance
20170361641 · 2017-12-21 ·

The flat foil printing press comprises an evacuable back-pressure plate (9), with suction regions (15k) which run in the sheet running direction (X) and which are next to embossing regions (16k), in which foil webs (6k) run. The suction regions are subdivided into several suction segments (10i) which are successive in the sheet running direction, and are each connected to a vacuum source (14) by way of a vacuum feed line (12i) via a vacuum switching element (13i). With the running-out of an embossed sheet (5), firstly all suction segments (10i) covered by the sheet are evacuated, and subsequently the suction segments which are no longer covered by the sheet are successively disconnected from the vacuum source. This results in an error-free separation of foil webs and sheets, for a greater picture quality and machine output.
