- said inking device comprising:
- an inking roller; support and moving means for moving said inking roller across said types as said printing head moves toward the label and while the label is not in contact with said types;
- inking roller guide means comprising a fixedly positioned and immovable guiding element supported on said frame and positioned and shaped to be in engagement with and to guide said inking roller to move over said types on a predetermined pathway with respect to said printing head; said guiding element being positioned and shaped so as to engage said inking roller at a side thereof away from the side contacted by said types and for pressing said inking roller against said types and against force exerted by said types against said inking roller as said inking roller rolls by said types such that the cooperative engagement between said guide means and said inking roller is the sole cause of the inking pressure of said inking roller on said types; said guiding element being shaped and positioned to remain in engagement with said inking roller over the entire said predetermined pathway of said inking roller and also to cause said inking roller to press on said types with a desired pressure over said predetermined pathway;
- said yoke end surface being spaced from said guide means such that at least part of said inking roller is normally positioned between them;
- said guide means comprising a fixedly positioned, immovable guiding element supported on said frame; said guide means having a first orientation for guiding said inking roller on a pathway that crosses the direction of relative motion of the labels toward and away from said types; said end surface having a second orientation that is oblique to said first orientation;
- a bearing plate connected with said inking roller and movable therewith; said bearing plate normally being in engagement with said yoke end surface, whereby upon relative motion of a label and said types toward each other, said end surface presses upon said bearing plate as said inking roller shifts in one direction along said guide means;
- said actuating lever being connected with said inking roller to cause said inking roller to move along said predetermined pathway as said actuating lever is operated.
- 42. The inking device for a labeling machine of claim 41, wherein said yoke end surface is part of said printing head.
- 43. The inking device for a labeling machine of claim 42, further comprising a pivot on said frame; said actuating lever being pivotally connected on said pivot, whereby said actuating lever pivotally moves with respect to said frame;
- an inking roller support between said inking roller and said actuating lever for translating the pivoting motion of said actuating lever into motion of said inking roller along its said predetermined pathway.
- 44. The inking device for a labeling machine of claim 43, wherein the size and placement of said bearing plate with respect to said inking roller determines the location of said inking roller with respect to said end surface and thus determines the pressure that said inking roller can exert upon said types under the influence of said guide means.
