Quelltext der Seite Translations:Die Geschichte der Marke Constructa/7/en

While the washing machines developed by Pfenningsberg were innovative, production still resembled a small factory. Ten appliances per day were being assembled some three years following the market launch. Reining therefore provided Pfennigsberg with a commercial advisor in the persona of Ernst Böcker. Annoyed by this, Pfenningsberg left the company. Washing machine production was modernized by Ernst Böcker. A larger production hall with simple assembly line production was established. The challenge now lay in stimulating demand for such a new and unknown product.<ref>See Constructa äußert sich zur Marktsituation, January 1960, Document collection folder (general) 1959-1965, Constructa company history, 60.11, page 2.</ref> The product was therefore actively advertised at [[Special:MyLanguage/Bildstrecke Constructa|exhibitions and washing machine demonstrations]] throughout the Federal Republic of Germany.<ref>See various material on organizing demonstrations in: Document collection folder (general) 1951-1958 Constructa, company history, BSH Corporate Archives and inform 82/4, page 15.</ref> And with great success – some 4,000 appliances per month were soon being sold. With a market share of 80 percent, Constructa was the undisputed leader in Germany on the washing machine market.<ref>45 Jahre Constructa. Anniversary Brochure.
