spral hose line

Spiral hose is a product that achieves high strength and durability by weaving thread into the hose.
This product is widely used in fields such as watering hoses and automobile wear harnesses.
We handle in-line spiral machines for spiral hose production lines that meet the needs for high-speed rotation and large bobbins.This allows the cooling water tank to be consolidated in one location, making it possible to make the line more compact.

Product Features

Rubber extruder

Abundant Product Composition met applications and needs you have!! The rubber extruder, which is one of our signboard products of Mitsuba Manufacturing Co., Ltd. has been adopted by many users both in Japan and overseas, with nearly 100 extruders annually since its establishment.
addition to its achievements and experience, we design screws and flow paths in-house based on material data that makes full use of measuring instruments such as Brabender viscometers and Capillary rheometers, and we also assemble in-house major parts with our own high-performance processing machines and skilled technicians.
Having small extruders like screw size φ20 mm to larger large extruders like φ200 mm, our extruders are used in various fields such as automobile hoses and tyres, building sealing parts, medical tubes, electric cables, and printing rolls and so forth. If advising us the application and specifications, we are glad to propose the most suitable equipment including front and rear equipment.

spral machine

  • A spiral machine that can handle a maximum rotation of 1200rpm and can also be equipped with a large-capacity bobbin.
  • Torque roller type or spring type can be selected.
    The torque roller type can set a wider range of tension than the spring type.
    In addition, tension adjustment time can be shortened because tension can be controlled by setting the torque roller.
  • A large volume of yarn is discarded to prevent hose failure due to reinforcing yarn breakage.
    The reinforcing yarn remaining volume management system developed by Mitsuba can manage the volume of yarn to be discarded to the minimum, and can greatly improve the cost.
