ホースを効率良く製造出来る効果がある。Further, the present invention includes a vulcanizer that vulcanizes or semi-vulcanizes the hollow tube rubber continuously extruded from the extruder, and a pinch roller device that tightens the vulcanized tube rubber from both sides. A braider device that applies a reinforcing layer to tube rubber, an extruder that extrudes cover rubber onto tube rubber, and a resin extruder that coats heat-resistant resin on cover rubber.
a vulcanizing device that vulcanizes the hose in which the tube rubber is coated with a heat-resistant resin via a reinforcing layer at a constant temperature; a cutting device that cuts longitudinally in the heat-resistant resin; a cooling device; It is composed of a resin stripping device that strips heat-resistant resin from the cooled hose body, and an air pressure injection device that injects a certain amount of air pressure into the hose body, which is installed on the winding device side of the hose body, so it is easy to use compared to conventional devices. It can be configured by simply adding a pinch roller device and an air pressure injection device that injects constant air pressure. Therefore, it does not require a large amount of equipment cost, and it is possible to efficiently produce rubber hoses with stable dimensional accuracy and stable quality. It has the effect of being manufacturable.
