The invention concerns a device for a roller body of a rotation roller with an outer hollow body that has a cylindrical shape and is built with an internal cavity, an inner body that has a cylindrical shape and is arranged in an assembly with the outer hollow body in the internal cavity of the outer hollow body, and a centring device that is used during installation of the assembly to centrally position the inner body in the internal cavity; a relevant material bridge in the opposing end sections of the assembly, whereby the relevant material bridge is formed by a filler, which is applied and cured in a space at the end section of the assembly between an inner surface of the outer hollow body and an outer surface of the inner body, which is in contact with the inner surface of the outer hollow body and the outer surface of the inner body and is fully formed between this area and forms a dimensionally stable connection between the outer hollow body and the inner body in the assembly. Furthermore, a printing roller adapter, a printing roller and a process for the production of a device for a roller body of a rotation roller are also envisaged.

A system and method for feeding a ribbon of un-lined label stock to a printer includes first and second, abutting rollers that cooperatively remove label stock from a roll. An optical sensor is disposed in a ribbon path between the rollers and the printer. The optical sensor determines a slackness level of the ribbon between rollers and the printer. Speed of a drive roller drive motor is increased when the slackness level is below a prescribed threshold. Speed of the drive roller motor is decreased when the slackness level is above a prescribed threshold.

The method relates to tape connecting device (1) and a method for connecting a first tape to a second tape for providing a tape string. In the tape connecting device (1) when continuously conveying the first tape an end section of the first tape is connected to a start section of the second tape by an adhesive connection by a liquid (in particular water) arranged in a connecting section. Furthermore, the invention relates to a method for connecting two tapes, a processing system and a use of a method.

The inventive tape connecting device (1) and the method can in particular be used for a continuous provision of a security tape for a security document as a banknote.

According to an embodiment, a fan unit holding mechanism includes an installation bracket with a slot, a projection portion on the bracket, and an elastic member at a bottom of the slot. The installation bracket receives a fan unit within the slot. The projection portion is inserted into an attachment hole of the fan unit when the installation bracket receives the fan unit. The elastic member comes into contact with the fan unit and presses against the fan unit.

A roller features a circumferential trench into which a wire is deposited from a wire dispensing head having a wire dispensing tip. A moving web of material engages the roller as the roller rotates. The wire dispensing tip engages sidewalls of the trench so that the wire dispensing tip remains in the trench as the roller rotates. Wire from the trench is deposited onto the web of moving material and is secured thereto by fasteners or tape or adhesive or the like.
