A yarn tensioning device is illustrated employing longitudinally spaced stacks of transverse cylindrical rollers, the lowermost of which open upon a yarn passageway for exerting tension upon the yarn at spaced points along the yarn path which extends longitudinally beneath the rollers, wherein an upwardly extending passageway opens laterally and is defined by an upwardly extending member and an overhanging flange so that the yarn may be conveniently fed under the ends of the lowermost rollers which project into the passageway and then into the yarn passageway and retained therein during tensioning.
