Abstract:
1. A folding device comprising: a first partial cylinder having first radial segments and a first partial cylinder circumference; a second partial cylinder having second radial segments and a second partial cylinder circumference, said first and second partial cylinders together constituting a body of a cylinder having a cylinder axis of rotation; means supporting said first partial cylinder and said second partial cylinders coaxially and each for rotation circumferentially about said cylinder axis of rotation and relative to each other; a first group of function elements on said first partial cylinder circumference; a second group of function elements on said second partial cylinder circumference; a separate electric motor for each of said first and second partial cylinders, each of said separate electric motors being mechanically independent of other cylinders and being adapted to coaxially rotatably drive its associated partial cylinder circumferentially about said cylinder axis of rotation; and a drive circuit adapted to drive said electric motors for said first and second partial cylinders at identical speeds to rotate each of said first and second partial cylinders circumferentially about said cylinder axis of rotation and with an adjustable relative phase position between said first and second partial cylinders.
