发明名称 Flexible strip heater
摘要 A strip heater for wrapping around and applying heat to elongate generally cylindrical objects has a thin, flexible, elongate fiber reinforced base with a uniform width along the majority of its length, resistance wire insulated within the base across a uniform portion of the width of the base and a flexible insulating layer having a width equal to that of the portion of the base containing the resistance wire and overlying only a portion of one surface of the base. The heater is designed to be wrapped around a cylindrical object, such as a communications cable, with the thicker insulating portions overlying the portions not having the insulating layer and abutting itself in adjacent turns around the object to position the portions of the base containing the resistance wire adjacent each other in the spiral adjacent the object.
