Abstract: An embossing device for tissue paper converting apparatus, includes a first roll and a second roll cooperating with each other to emboss a web of tissue paper in-between, first protrusions on the circumference of the first roll cooperating with the second roll to form a first nip with a first gap in-between, second protrusions on the circumference of the first or second roll cooperating with the other of the first and second roll as a counter roll to form a second nip with a second gap in-between. The embossing device further includes an adjusting means for selectively adjusting the second gap of the second nip of some or all second protrusions.

Abstract: The invention relates to an apparatus for image formation on cylindrical surfaces of printing machines. The object of the invention is to provide a compact image formation unit with a broad application rage regarding its usage, the sequence in time and variation in time of the process steps. The invention accomplishes this by processing units mounted on slides movable separately on a common cross bar. Each slide carries at least one processing unit. The cross bar is located in a gusset area between a plate cylinder and a blanket cylinder.
