An application roller (212) for a labelling device for applying self-adhesive labels comprises a cylindrical inner sleeve (211). It further comprises a cylindrical outer sleeve (212) whose internal diameter is greater than the external diameter of the inner sleeve (211). An intermediate sleeve (213) disposed between the inner sleeve (211) and the outer sleeve (212) with radial spacing between said two sleeves is connected with one end to the inner sleeve (211) and with the other end to the outer sleeve (212).

Application roller for a labelling device

A device for mounting an ink roller made up of a cylindrical ink carrier body and having on its ends, end-disks. The diameter of these end-disks is larger than the ink roller body. Such ink rollers are used in printing devices in order that the printing types characters are inked prior to the actual printing process. To simplify the handling of such ink rollers, especially when exchanging a used ink roller for a new ink roller while at the same time avoiding the smudging of fingers or clothing of service personnel, the device is provided with two U-shaped cups that are interconnected and whose widths--at the open ends--are equal to the width of the new ink roller. The depth of these cups is equal to the diameter of the end disks of the new ink roller, and the cups are provided on both their sides with areas which act as clamps for the end disks and whereby the width of one cup--in its entire dept--is constant; while the width of the other cup increases from the open end in the direction of the closed-off end.

Means for accommodating an ink roller

The present invention relates to a printing mechanism for printing bar codes on pressure-sensitive labels adhering to a carrier tape. The printing mechanism includes a print wheel on which a plurality of type rings rotatable about a common axis relatively to each other are mounted. The carrier tape with the pressure-sensitive labels adhering thereto is pressed with the aid of a pressure roller against the print wheel. To enable the bar codes to be printed to be read without error with electrooptical reading devices, high requirements are made of the printing quality of the bar codes as regards uniformity and contrast. To meet these requirements the type rings comprise a cylindrical peripheral surface on which bar code types of resilient material are formed with which an inking means is in contact; the pressure roller is rotatable about an axis extending parallel to the axis of the type rings and consists of non-resilient material.

Printing mechanism for printing bar codes on pressure-sensitive labels

A counting or printing mechanism for consecutive counting or numbering, in which a number or printing wheel is provided for each numerical place and the number or printing wheels are mounted on a common shaft. The number or printing wheels are turned by advancing elements which are connected loosely but so as to transmit force and designed to deflect one another. These advancing elements may, for example, be pawls disposed on an inner ring or coupling discs disposed on a side surface of the number or printing wheels.
