    摘要： A method and device for unwrapping self-adhering films at reduced noise levels are disclosed. The method and device include means to maintain a sufficiently high unwrapping take-off angle during the unwrapping and dispensing or unwinding of film rollstock. Suitable means provide for substantial acceleration and adjustment of the rollstock rotational speed relative to the speed of the first power driven member of an unwrapping apparatus, or the use of one or more carefully positioned deflector members. The method and device is particularly useful in unwrapping and dispensing operations of high cling stretch wrap films involving the use of turntable-style power driven equipment as well as in unwrapping and unwinding operations of pressure-sensitive adhesive tapes.
