Abstract
Przedmiotem zgłoszenia jest rolka prostująca prostownicy rolkowej przeznaczona do prostowania zwłaszcza szyn kolejowych lub tramwajowych, charakteryzująca się tym, że powierzchnia robocza rolki prostującej jest na całej swojej długości wklęsła przy czym wielkość wklęsłości jest zmienna począwszy od skrajnych punktów opisanych promieniami stanowiących jednocześnie maksymalną szerokość powierzchni roboczej rolki prostującej, aż do środka osi symetrii rolki prostującej, gdzie zbiegają się linie pochylone względem siebie pod kątem rozwartym w zakresie od 178° do 179,5° i zapewnione jest łagodne ich połączenie za pomocą promienia, w tym obszarze rolka osiąga maksymalną różnicę średnic położonych w punktach skrajnych, najbardziej wypukłych i w osi symetrii rolki prostującej.
