ABSTRACT:
Braking apparatus for a web transport system to move a web between rotary members wherein at least one motor is provided for moving the rotary members to drive the web. One of the rotary members is coupled to and drives a first mechanism; and another movable member is coupled to and drives a second mechanism which mechanisms exert retarding forces on the respective rotary members such that when the driving force from the motor is removed and the rotary members are no longer driven, the retarding forces exerted thereon act to brake the rotary members.
In an embodiment wherein the shoeless braking apparatus is used in a tape recording and/or playback device, one motor drives a take-up reel rotary member. In addition, a second motor may be provided to selectively drive the take-up reel rotary member in a "fast-forward" direction and to selectively drive the supply reel rotary member in a "rewind" direction. When the driving forces exerted by the respective motors are removed from the supply and take-up rotary members, the drag from the driven mechanisms coupled thereto is sufficient to brake the rotary members without the assistance of brake shoes. In one example, such driven mechanisms are indicators for providing indications of the amount of tape which has been transported and the relative position of the tape then being moved with respect to the total length of tape.
