Title: Cutting device with slide and two knife blades - designed esp. for cutting dictating machine tapes
Inventor: STOWASSER KURT
IPC: G11B27/06
Filed: 1973-08-24
Abstract: The tape cutting arrangement comprises a slide which holds a knife holder and a controlling linkage with a longitudinal slit into which fits a cam arranged on the holder. Two knives held by the holder have blades with cutting edges which face outwards in opposite directions. One of the cutting edges serves to cut the cutting side of the tape, while the cutting edge of the other blade is used to cut through the tape. The cutting device is operable in both moving directions of the tape. Due to the groove effect the cutting knife meets a smaller cutting resistance and even a slow driving force will suffice to give a perfectly clean cut.
