These press­es are of Ger­man descent — made by Rock­stroh-Werke AG of Hei­de­nau — but were made in the UK by Frank F Per­shke.

Rock­stroh-Werke AG made three mod­els of machine -

  • Vic­to­ria (Mod­el ‘B’)
  • Auto-Vic­to­ria (Mod­el ‘C’)
  • Kobold

The three UK-made mod­els were -

  • Vicobold
  • Autovi­cobold
  • Autovic

General Principles

The key fea­ture of these machines is that they employ a ‘par­al­lel plat­en’ approach. The platens are not hinged (like most oth­er press­es), but runs on rails in the ver­ti­cal posi­tion. This ensures that impres­sion is even over the face of the forme.

Ink­ing is by a rotat­ing cylin­der at the head of the machine — rather than an ink­ing disk. The machines are based on the Vic­to­ria Heavy Art Plat­en.

This machine is hand-fed and fol­lows the same prin­ci­ples as the oth­ers in the series. Ink is sup­plied to the ink­ing drum through a screw con­trolled duct, and trans­ferred to the forme with two rollers. Impres­sion strength can be changed with a sin­gle nut at the back of the plat­en: the par­al­lel approach takes care of all of the forme with that one change.

There were at least two mod­els — the Mod­el ‘C’ which was motorised; and a Mod­el ‘T’ run with a trea­dle.

This machine is essen­tial­ly the Vicobold with an auto­mat­ic feed and deliv­ery sys­tem. A sell­ing fea­ture was that the feed and deliv­ery sys­tem could be wheeled away when need­ed: allow­ing the machine to be used as a hand-fed machine, and also to allow open access to the work­ing area dur­ing set-up.

This machine is a larg­er size than the oth­er two mod­els, and occu­pies a sub­stan­tial­ly larg­er space. It was sup­plied with an option­al feed sys­tem. Ink­ing is by means of three rollers: two are in con­tact with then forme on the way ‘down’, and the third roller is engaged with the form only on the way ‘up’. There are two addi­tion­al rollers in the ink­ing mech­a­nism for ink dis­tri­b­u­tion. An auto­mat­ic wash-up sys­tem is also includ­ed.
