    摘要： A process is disclosed for producing a transfer member to be used in a transfer system by which a toner image formed on a first image-bearing member is transferred to a second image-bearing member. The process comprises the steps of melt-extruding an extrusion material from a circular die of an extrusion/forming apparatus into a cylindrical film; and measuring the circumference of the cylindrical film and sending the resultant information to the extrusion/forming apparatus to adjust the circumference of the cylindrical film. Also disclosed are a transfer member produced by such a process, and an image-forming apparatus having the transfer member. The transfer member can be produced as an intermediate transfer belt or a transfer belt which have a stable peripheral length.

    摘要： A method and apparatus for blown film extrusion is described. An annular die receives a molten material and extrudes a film tube. At least one cooling ring is positioned adjacent the annular die for passing an air stream along a particular surface of the film tube. A blower entrains and supplies air to the cooling ring. A flow sensor is positioned in an air flow path intermediate the at least one cooling ring and the blower. It provides a mass air flow signal which is a measure of air mass flow per unit time. An adjustable air flow attribute modifier is placed in communication with the air flow path and operates to selectively modify the air mass flow per time unit. A controller member is in communication with the flow sensor and the adjustable air flow attribute modifier, for receiving the mass air flow signal and for controlling the adjustable air flow attribute modifier to provide a preselected value of air flow in terms of air mass flow per unit time.

    摘要： To determine and/or automatically control the degree of orientation of tubular films which have been made in a film-blowing plant including an extruder having a film-blowing head and apparatus for internal cooling and also including flattening and take-off apparatus, the rate of exchange of the air for internal cooling, the speed of the extruder, the temperature of the plastic composition being extruded and/or the take-off velocity are controlled. To ensure that the degree of orientation can be determined and/or automatically controlled in a simple manner and without an occurrence of trouble, that shape of the flaring portion of the bubble which corresponds to the desired degree of orientation is determined and/or adjusted and is recorded as the desired shape of the bubble. The actual shape of the flaring portion of the bubble is detected and compared with and adapted to the desired shape.

    摘要： In a blow film extrusion system in which film is extruded as a tube from an annular die and then pulled along a predetermined path, an apparatus is provided for gauging and controlling the circumference of the extruded film tube. At least one transducer, preferably ultrasonic, is mounted adjacent the extruded film tube for transmitting and receiving interrogating pulses along paths normal to the extruded film tube, and for producing a current position signal corresponding to the circumference of the extruded film tube. The current position signal is continuously compared with at least one previous position signal, preferably with a computer program resident in a controller memory. If at least one preselected condition is violated, the current position signal is disregarded in favor of an estimated position signal. The quantity of air within the extruded film tube is varied in response to either the current position signal or the estimated position signal to maintain the extruded film tube at a preselected circumference. The transducer may be mounted to an adjustable sizing cage, and is thus moveable inward, outward, upward, and downward relative to the extruded film tube as changes are made in its circumference or frostline position.
