Abstract
A tape entrainment device especially for a magnetic recorder, comprising a roller (11) tangential to the periphery of each of the reels (9 and 10) and an endless belt (12) which passes between the roller and the reels and engages an arc of the periphery of each of the latter. The roller, which entrains the tape by friction by means of the belt on which it bears, is integral in rotation with an element (24 and/or 26) which is entrained on the one hand in rotation about its own axis and on the other hand is forced mechanically to move relative to the support along a circular path as close as possible to the path of the roller.
