Winding Shafts, Adapters, Clamping Chucks, Rollers

Winding Shafts

Air shafts and clamping chucks for winding and unwinding of web materials are available to suit various applications. Individual design for specific dimensions and application conditions ensures an optimal price/performance ratio. In conjunction with safety chucks, brakes/clutches and web tension controls, attractive complete solutions from one source are also available.

Aluminium Profile Shafts

This type of air shafts is based on high strength aluminium profile and includes a special flat hose system. The full-length expansion elements can clamp wide and also very narrow rolls perfectly. These shafts are characterised by simple construction and low own weight. Attractive purchase prices and minimum maintanance costs are other big advantages and optimize your payback period.

Depending on the individual application, these shafts can be fitted with different types of clamping elements:

  • Aluminum clamping elements with longitudinal profiling 
  • Solid polyurethane elements
  • Segmented elements

Air shaft with central rubber tube

This type of winding shafts is based on a tubular main body which is made of aluminium, steel or alloy steel. The robust central rubber tube activates the different types of expansion elements. Each shaft is individually designed and manufactured in order to suit the corresponding requirements. Heavy duty applications, high roll weights and torque transmission can easily be accomplished with this type of air shafts.

Further characteristics of these shafts are a durable construction and material quality, therefore a broad range of demanding applications can be covered. Attractive purchase prices and minimum maintanance costs are other big advantages and optimize your payback period.

Pneumatic Shaft Adapter

This type of winding adapters is based on high strength aluminium profile and includes a special flat hose system. The full-length expansion elements can clamp wide and also very narrow rolls perfectly. They can be used in combination with expanding and non expanding shafts and offer a simple and cost-effective solution for using different core diameters.

Torque Clamping Chucks

These mechanical clamping chucks are activated by the web tension and can be used at shaftless unwinders and rewinders.

Features and characteristics:

  • mechanical centric expansion by web tension
  • no air or hydraulics necessary
  • shaftless winding
  • constant expansion force over an expansion diameter of 10 mm
  • frictional clamping prevents damage to cores
  • core diameter from 70 mm
  • virtually all standard flange mountings available
  • simple design, low maintenance, minimal spare parts costs

We manufacture clamping chucks according to individual specifications.

Reduce downtimes with modular clamping chucks.

This system allows quick replacement of the expansion units. The expansion units consist of an main cage in which expansion elements are anchored. The outer diameter of the respective expansion unit corresponds to the required core inner diameter. When using different core inner diameters, the suitable expansion unit can be attached to the existing flange/journal unit.

Guide Rollers

Guide rollers or precision guide rollers are tailor-made to suit almost any area of application. Different materials, coatings and surfaces are available.

Options

  • Hard coating, hard chromium plating and hard anodising
  • Plasma coating
  • Ceramics and Teflon coating
  • All types of rubber coatings
  • Grooved and knurled roller surfaces
  • Polished surfaces
