The small diameter rolls are circumferentially spaced from each other a distance that is equal to the spacing between the leading edge and trailing edge of a plastic label carried on the surface of a transfer drum. The small gravure rolls are relatively rotatable with respect to the large roll and are supplied with solvent from behind within the large roll.

Abstract: A device for applying a protective coating to the weld or solder seam of a can body has an application roller (2) serving to apply a coating material inside a region covering the seam at the inside (15) of the can body. The roller periphery has a cross-sectional profile (5) comprising at least one depression (10) in a middle region (9) of a middle portion (6) having a region width of less than 60% of the width of the middle portion (6). The profile (5) further comprises at least one salient point and/or at least two points of inflection in this middle region (9).

Abstract: A horizontally moving belt has a waffle grid surface into the compartments of which dyes are injected in accordance with a desired color pattern to be printed. Carpeting is moved adjacent the waffle grid surface with the pile facing down toward the grid. A counter roller supports the waffle grid at the printing station, and an oppositely disposed protuberance-bearing pressure roller pushes the backing of the carpet so that the pile enters the compartments of the waffle grid and is immersed in the dye pattern. The protuberances ensure adequate immersion of the pile while permitting escape of air and avoiding squeezing of the dye from the pile, which would otherwise occur by engagement of the pressure roller with the grid walls in the absence of the protuberances. The angle of approach of the carpet to the printing station is slightly inclined from the horizontal to ensure a gradual depression of the pile and to avoid rolling the dye out away from the nip region of the printing station.
