Elmoprint produces Elmo-roll hot-ink rotor printers for date coding, batch numbering and more. Elmo-roll is a compact, uncomplicated coder for building into packing machines. Elmo-roll is a fast, reliable printer which is ideal if the print itself is not required to be of letter-printing quality.

The principle of hot-ink printing is to transfer hot ink from an ink roller to packing film by means of a heated rotating typeholder where the type is alternately in contact with the ink roller and the packing film. When the ink is deposited on the “cold” film, it solidifies immediately.

Elmo-roll is available in two models, designed to run clockwise and counter-clockwise respectively and with two different types of controls.

 

The R-35 M is a fully mechanised printer driven by the friction of a rubber wheel against the packing film. The typeholder is customised for customer preferences, with the option of printing all the way around the typeholder.

The R-35 EM is also friction-driven but has a built-in clutch which enables the position of the print to be determined by means of a photo code on the packing film, for instance.

A wide selection of accessories are also available for the Elmo-roll coders. There are ink rolls in several colours and types as well as typeholders and typefaces for every need. The ink for the Elmo-roll printers is supplied in rolls, which are composed of a foam core into which thermal ink has been pressed. The ink is permanent at room temperature and does not begin to rub off until around 90°C.

The ink rolls are available in trays of 25 in the following colours: black, white, blue, red, yellow, green and brown. In normal use, an ink roll prints around 100,000 dates.
