Heating rolls that are generally used in the manufacturing process of synthetic fiber yarns or films are those that are heated by a heat source such as induction heating or electric heating wires, or those that are heated by a heated heating medium that is supplied to the roll as a heat source. There are some that are configured to be heated.

。Taking film manufacturing as an example, in recent years there has been an increasing need to increase production speed in order to improve productivity. that time,
In order to heat the rolls of existing equipment to a specified drawing or heat treatment temperature, it is necessary to heat the rolls to a considerably high temperature. adhesion of the film to the surface, dirt on the roll surface, and meandering of the film.
フィルムの巾変動が生じるため、これらに起因して結局
生産速度が制約されるという問題があった。Since the width of the film fluctuates, there is a problem in that the production speed is ultimately restricted due to these fluctuations.

術から加工性が保障される肉厚(下限)は1a1以上で
あり、厚みの精度も低く表面の温度斑も避は難い。Therefore, it has been proposed to use non-viscous rubber or resin as a coating material for the roll, which does not cause film adhesion, circle stain, film meandering, or width fluctuation even at such high temperatures. Rubbers or resins such as silicone resins, acrylic resins, chloroprene rubbers, and fluororesins are used as materials for coating the rolls. However, the wall thickness (lower limit) at which workability is guaranteed based on the current rubber coating technology and surface processing technology for rolls is 1a1 or more, and the accuracy of the thickness is low and temperature unevenness on the surface is unavoidable.

命を長くできるゴムあるいは樹脂波No−ルの加熱方法
を提供するものである。When such coated rolls are heated using conventional heating methods, steady and uniform heating is difficult due to the low thermal conductivity of the coated rubber.Moreover, when trying to obtain the required roll surface temperature, the metal surface of the inner layer of the roll is heated. The temperature must be even higher. Therefore, although the roll surface temperature is within the heat resistance range of the coating material, the coating material or the adhesive layer between the metal and coating material must be heated inside the coating material, that is, on the side that contacts the metal surface of the roll. As a result, the heat-resistant temperature may be exceeded, causing deterioration of the coating material and adhesive layer, resulting in a shortened service life of the roll. The present invention solves the above-mentioned problems and provides a method for heating rubber or resin corrugated nozzles that can perform uniform and steady heating and extend the service life.

熱媒体を熱源とするもの等従来からの方法による。(Means for Solving the Problems) That is, the present invention is a roll heating method that uses another heating roll in contact with a rubber or resin coated roll as a means for heating the roll. The material of the rubber/resin covering the roll is not particularly limited, but it is better to use a material that exhibits non-adhesion at high temperatures than hard chrome processing or ceramic processing, or a rubber or resin such as silicone, acrylic, chloroprene, or fluororesin. Further, although an internal heating device is not essential, from the viewpoint of stability of heating temperature, it is better to heat the inner layer of the covering rubber or resin to the same temperature as the required surface temperature. On the other hand, the surface material of the roll that heats the rubber or resin coated roll is preferably treated with hard chrome or ceramics in terms of heat resistance. The means for heating these rolls is a conventional method such as induction heating, a heat source such as a heating wire, or a method using a heated heat medium as a heat source.
