Brakuje mi pomysłu na określenie, który wałek powodował odkształcenie blachy w "kołyskę".
Obejrzałem parę filmów o walcowaniu metalu, na jednym balach z walcarki wychodziła wygięta do góry, a na następnym wyginała się do dołu. Jestem bardzo ciekawy, od czego to zależy..., od materiału, szybkości walcowania, ilości walców (2,3 itd.) ?
Czy trojaki malborskie wycinano wycinakiem, czy nożycami? Mam 4 sztuki i jak oglądałem ranty, to wyglądają jakby wycięto je wycinakiem.Czy w literaturze jest gdzieś zdjęcie XVI wiecznego wycinaka?
Ciekawy przykład przesunięcia obu stron monety. Trojak ryski 159?

According to Taxation document of 1618, the mint was equiped with different kinds of machines: 3 rollings mills (ZehWerck) which created smooth strips of metal (1,000 thalers each), 4 presses (Prege Werck) (90 thalers each), which pressed the image of the dies onto the blank strips and some less expensive instruments: 2 hammers, 2 awnings, several pliers, shuffles, boxes, weighs, etc. The total value of 26,243 marks 27 schillings or more than 4,000 thalers. In addition, 16 horses were kept at the mint stables, but it is not certain in which minting processes they were used
According to the 15 May 1646 calculations drawn by H. Wulff, less than 40 people were employed at the mint: 26 workers, journeyman, supervisor and bookkeeper. Variety of craftsmen were also employed: 3(?) blacksmiths, 3 die cutters, silver dealer, stablemen, etc. H. Wulff drew up the list only of the hired staff under his command. Mint master andwarden were not included, because they were hired by town council
In search of a new mint master the town council decided to employ Gerhard Philips from Riga, who was reputedly a relative of the mint master of the Swedish crown mint in Riga Marsilius Philipson – a man who came from the Low Countries and who had worked in the mint of Elbing (Elblag) from 1628-1634. (dopisek) In spring 1648 the Tallinn mint was rented out to Philips, and in September he gave his oath of office.
