Abstract

Reel 30 for strip record 50 of either magnetic tape or photographic film or the like is driven by roller 72 frictionally engaging the rims of reel flanges 36 and 37. Leader 60 of record 50 is stripped from sealing grooves 52 and 53 of reel 30 by stripping spur 91. Any tendency for leader 60 to slip within grooves 52 and 53 is overcome by leader flexing roller 80. The latter is of such dimensioning that leader 60 is flexed inwardly as long as it is in grooves 52 and 53 and reel 30 is in the machine with which it is associated. Preferably roller 80 is made of rubber or other material having a high coefficient of friction on the leader 60 material.
