Abstract: An over-printer comprises a label web support reel, an inking roller and a type drum. The type drum co-operates with a rotary platen which is freely rotatable on a shaft. The type drum and the platen have concentric cams which serve to index a web of labels through the printing station, the cam of the type drum being secured for rotation therewith.The inking roller is built up from a multiplicity of absorbent paper discs and the type drum has one arcuate recess to receive type rails and at least one cylindrical recess to receive an adjustable facet printing mechanism.Can be used for printing label and other webs.

Abstract: A label web overprinting machine in which the label web is indexed through the apparatus by two opposed rollers, one of which has a recess in its periphery defining a step and the other of which is movable through a small distance to form a nip for drawing the web forwardly through a printing station of the machine.A solenoid controls the movement of the movable roller and by a machine cycle operated switch the solenoid is energized to bring the one roller into substantial contact with the other at an instant when the recess of the one roller is directed towards the other roller. Immediately the step of the roller contacts the other roller, the web is indexed forward and the solenoid is subsequently deenergized by a photo-electric cell arrangement arranged to detect a particular indicia on a label or the downstream edge of a given label.

Abstract: A label applicator and registration device for such an applicator are disclosed.The applicator includes along the path of a web including both a backing strip and a series of contact-adhesive coated labels, a web reel mounting, a brake for preventing overrun of the web from its mounting and to provide tension in the web, a registration device of generally triangular section, a dispense edge for detaching the labels from the backing strip, a take-up mounting for spent backing strip, and an elongate slide operable by a "stamp" action to actuate the various parts enumerated.The registration device may co-operate with projections which engage transverse edges of the device.The applicator can be used wherever price and similar labels are to be applied to goods. The registration device is applicable to label applicators whether powered or manual and is disposed upstream of any dispense edge of such applicators.
