A planetary inker for an offset printing press which uses only a single ink form roller but is substantially ghost free. A unique arrangement of distributor rollers operably associated with the form roller are present in sufficient number and of relative diameters with respect to each other and to the form roller to assure complete smoothing out of ink supplied to the form roller in conjunction with total elimination of all plate-derived latent images on the surface of the form roller before recontacting the plate on the plate cylinder. Especially efficient transfer of ink from the supply fountain to a drum roller in rolling contact with the form roller ahead of the distributor rollers is obtained in a preferred embodiment by the use of a pair of ink transfer ductors which are alternately intermittently shifted into engagement with the fountain ink ball and then the form roller vibrator. The relative time of engagement of the ductors with the ball and the vibrator may be selectively varied by the operator.

Planetary inker for offset printing press

A highly efficient, shear-cutting, multiple die apparatus and method for interlocking elongated, multiple-sheet glued webs such as business forms or computer print out paper during fabrication thereof is provided which positively locks the web sheets against relative shifting as can occur when the web is zigzag folded, in order to prevent 'tenting', or permanent, glue-set misalignment between respective web plies at the fold lines thereof. The preferred apparatus includes individual, mated pairs of rotatably mounted, transversely oriented, multiple-blade, pointed, web-shearing and deforming dies which are rotated to cooperatively engage, shear-penetrate and deform a moving web to produce a series of transversely extending, side-by-side, marginal, alternately displaced interlocking strips which effectively prevent significant relative longitudinal shifting between the web plies. The blade tips of the cooperating dies interfit during the web-shearing and displacing operation and serve to provide equal support and driving force for the web on opposite sides thereof, so that the web experiences minimum disturbance and no initiating causes for web skewing. The blade tips are contoured such that the opposed ends of the shear-cut strips remain connected to the web, to thus provide the most desirable positive web interlock, even at high or varying web speeds. In preferred forms, press-ironing rings are rotated with the interlocking dies for ironing the glued portion of the web in conjunction with formation of the interlocking strips.
