In Antwerp, Arthur Bursens built several hundred relatively small roll and book-operated café orchestrions under the trade name "Ideal" and "Arburo" (Arthur Bursens and (Gustav) Roels). Roels was an early business partner, succeeded by Frans de Groof. The smaller cafes of the Antwerp area were Bursens' main customers, as these premises often did not have space or income to justify a larger (Mortier or Decap) dance organ. A coin was dropped into a wallbox that allowed one tune from a roll that usually had three or four tunes on it to be played. At the end, the roll would rewind ready to play from the beginning again. Multi-tune rolls were produced frequently to keep up with the demand to hear the latest popular hits.
