Title: Production of heat fixing roll for copying machine
Inventor: NAGASAKA HIDEO
IPC: H05B3/00
Filed: 1987-10-29
Abstract: PURPOSE:To obtain a high-performance heat fixing roll of a low cost by forming a reinforcing insulation layer on the inside surface of the groove in the trace after a masking material is removed, then subjecting a yarn-like antistick material to painting in the stable of winding said material in the spiral recess formed on the surface at this time. CONSTITUTION:A thin film-like insulation layer 2 is formed by plasma thermal spraying of alumina, etc., on the surface of a hollow metallic pipe 1 and a metallic wire 3 is spirally wound thereon from the outside thereof. For example, nichrome, alumina-nickel mixture or the like is thermally sprayed on the form of a thin film by a thermal spraying torch 4a between the spiral pitches thereof to form a heating resistor layer 4. The metallic wire 3 is then removed to form the groove in the trace after the removal and the reinforcing insulation layer 6 is formed on the inside surface of the groove. The yarn-like antistick material 8 is wound in the spiral recess 7 formed at this time and is painted thereon with, for example, a PFA resin or the like, by a powder painting method to form an antistick layer 9. A slight projection 10 formed on the outside of the yarn-like antistick material 8 is polished and smoothed. The direct heat type fixing roll is thereby obtd. at a low cost.
