Abstract: A method for embossing products with a rotary embossing device includes controlling the rotation of at least one embossing roller as a function of marks that are present on the products and are detected by sensors. A folder gluer having a rotary embossing device is also provided.

Abstract: A rotary embossing device, in particular for making Braille embossments, includes a drive shaft and at least one embossing tool disposed thereon. The embossing tool includes a roller body, a mounting system and a tool sleeve. The tool sleeve is mounted to the roller body by the mounting system. The mounting system includes at least one mounting ring disposed between the roller body and the tool sleeve. The at least one mounting ring is advantageously engaged with an adjustment device for rotating the at least one mounting ring to adjust the angular position of the tool sleeve. The mounting ring includes at least one elastomeric ring and the mounting system further includes an axially displaceable mounting cover for compressing the at least one elastomeric ring. Tool sleeves can therefore be easily and quickly mounted and adjusted.

Abstract: A printing device for producing finished product by one-pass sheet-feed may include a sheet-conveying unit, stamping-control units, a die-cutting unit, a waste edges removing unit, a blanking unit, a waste removing unit, and a conveying mechanism. The operation method of the device may include transferring a single sheet to the stamping-control units by the sheet-conveying unit, gripping and transferring the sheet to the stamping-control units by a gripper bar, to stamp or indent; transferring the sheet to the die-cutting unit to complete the die-cutting work; transferring the sheet to the waste edges removing unit to remove part of the waste edges; transferring the sheet to the blanking unit to collect all finished product; and transferring the last remaining waste edges to the waste removing unit.
