Air shaft Description

What is an Air Shaft?
  Air Shafts, also commonly known as Air Bars or Air Mandrels, are used in the manufacturing processes for fitting into a core onto which materials such as paper, card and plastic film are wound. An Air Shaft is designed so that, on fitting into a core, it can be readily expanded, thereby achieving a quick and firm attachment. It may also be easily deflated to facilitate easy withdrawal of the shaft after winding of product is complete. Their efficient design makes them ideal for mounting onto bearing housings to enable the winding or unwinding of rolls of stock material with the minimum of equipment down time. The advantage of using an Air Shaft is its ability to grip the core, without damage, whilst providing a positive interface to control the web via motors and brakes. Air Shafts are available as either Lug Type (with bladder down the centre) or Strip Type (bladders on the periphery of the shaft).

Lug Type Air Shaft

  Lug type Air isthe most popular and versatile of the types of Air Shafts. They are available in sizes ranging from 25 mm to over 300mm, manufactured in Aluminium, Steel and Carbon Fibre where applicable. Shafts are bespoke and manufactured to the customer’s requirements to suit new or existing machinery. They are economical to repair and maintain, with a wide range of spares held on-site for immediate despatch.

Leaf Type Air Shaft

 A leaf Air shaft is recommended when thin wall cores requiring sensitive but positive gripping are to be used. The design ensures a high level of concentricity is maintained and core distortion kept to a minimum, achieved by 360° gripping of the core, with the leaves being machined to suit the core diameter when expanded. Rimor Converting can supply these shafts with Aluminium or Steel leaves, depending on the application. This Leaf shaft can also be used for coreless applications, where there is a requirement to wind the material directly on to the shaft. The standard leaf shaft design is modified to incorporate a bar along the length of the shaft to trap the web.

Strip Type Air Shaft

 

   Our high quality Extruded Aluminium Air Shafts have a high strength-to-weight ratio, therefore substantial weight savings are achievable when compared to conventional Aluminium or Steel Air Shafts. This, in many cases, replaces the need for high cost Carbon Fibre shafts. The multi-bladder design offers many features including the benefit of low air volume for quick inflation and deflation. Continuous gripping lugs make the shafts ideal for both multi-slit and continuous core applications, whilst providing quick and easy maintenance, without the need for special tools.
