Unidirectional Friction Shaft with Double Row of Expanding Balls

Particularly indicated for the rewinding of reels of materials with different thicknesses over the width of the web maintaining at the same time an equal tension as in the case of multiple slit reels.

Recommended for use on slitting and rewinding machines, this friction shaft ensures from the first runs an equal and uniform winding of each single reel, even the narrowest webs.

The friction force is regulated, when the machine is running, by a continuous air supply at a pressure ranging from 0 to 6 bar through a rotating joint connected to the axis of the shaft.

This pressure allows the special keys to expand against the friction elements positioned along the carrier shaft and therefore transmits the necessary torque to the individual reels suitable to ensure a uniform winding.

A simple turn of the cores on the friction element provides a firm radial and axial grip eliminating the need for any spacers.

Benefits

  • Fast and simple cores loading and positioning
  • Centered cores on friction rings and held firmly in place until each reel is fully wound
  • No spacers required
  • Slipping occurs inside the shaft so no core dust is created
  • Opportunity of interchanging friction rings for different diameter cores on the same shaft
  • Suitable for carton and PVC cores
  • Excellent friction sensitivity
  • Opportunity of rewinding multiple slit reels with variable widths on one shaft
  • Simple reel release and removal for rapid changeovers eliminating costly down-time
  • Easy substitution of expanding friction key rows on carrier shaft
  • Delivery time 4/6 weeks
Features

  • Hard chromium-plated ground steel carrier shaft
  • Dynamically balanced expanding carrier shaft
  • 3″ and 6″ friction rings using the same central shaft
  • Available for cores diameter from 50 mm up to 300 mm
  • Minimum reel width 7 mm for 3” cores
  • Exclusive interchangeable friction key rows that, in contact with friction rings, transmit the required torque to individual reels suitable to ensure an uniform winding
  • Axial or radial inflating
  • Opportunity of retrofitting on existing machines
  • Custom made steel journals to suit any machinery
  • Opportunity of radial inflating through special rotating joints of I.E.S. production (steel or aluminium execution)

Pneumatic shafts with Independent and Interchangeable Key Rows

They have five or more interchangeable key rows with independent air tubes each one with its own retention valve.

Because if one or more air tube should accidentally lose air, the others remain inflated and the job can be finished in any case.

Because the repair can be postponed to when the machine is stopped for other reasons. The faulty key row is easily identified being it the only one deflated. The repair does not take more than a few seconds by simply replacing the faulty key row with a spare new one.

Because they allow the cut of very narrow slits.

Because they don’t present the pumping effect common to shafts with one or more dependent air tubes. In fact the air cannot be pushed from one air tube to another by the weight of the reel while the shaft is rotating and even the heaviest reel remains perfectly centered even at very high speeds.

Because they grip the core along the entire width. The short keys rise uniformly providing continuous shaft to core contact even in the case of irregular cores.

Because they are extremely light. An aluminium shaft with body length 1,6 mt suitable for 6″ inside diameter cores weighs only 25 kg.
Despite this all the air tubes inflate and deflate at the same time with one simple operation like common pneumatic shafts.

Fitted with Nylon keys (black) suitable for cardboard cores or PVC keys (red) suitable for plastic or steel cores.

Suitable for entire rolls or very narrow slits.

Inflated to 6 bar, these shafts are able to transmit a torque of 190 daNm per linear meter of 3” cardboard core.

Minimum maintenance, spare key rows ready for replacement, steel end-blocks, air tube, protective steel and nylon strip, keys, springs and air valves are already included in a spare interchangeable key row. It can be changed easily in a few seconds, by unscrewing and rescrewing 2 cup screws, without stopping production.

Expanding air shafts with interchangeable key rows are also available in “hybrid” version, that is with expanding gripping keys for locking core and parallel mechanical system with precentering balls.

Pneumatic Expanding Shaft with Pre-Centring Core System

Pneumatic self-centring version takes advantage of tried and consolidated pre-centring IES system developed and improved over the years.

Mentioned system enables a truly concentric winding at any speed and under the heaviest loads and more demanding working conditions, so that pneumatic shafts equipped with such a system are particularly suitable for all those applications where low vibrations and high line speed are required.

Not to mention the consequent reduction in wear resulting from drastic shut down of vibrations, which are the main reason of wearing out of supports.

Pre-centring system which mentioned shafts are equipped with, is actually a combined system consisting of independent expansion element units.

First series of interchangeable steel key-rows expand before all the others, thus making the core well precentered and ready to be locked.

Only after that, second series of key-rows, fitted with PVC or Nylon gripping keys, expand and locking firmly the core.

Core has been properly centered by the first series of key-rows which actually prepare the core in perfectly concentric way compared to the body shaft.

About us

Company details

Since 1965 I.E.S. Srl is at the service of the printing, paper and converting industries with the in-house production and sale of technologically advanced expanding air shafts appreciated in Italy and all over the world for their high quality standard.

Their exclusive design and operational features, patented world-wide, distinguish them from all the others present on the market.

From the very beginning our primary objective has been to provide shafts that are extremely reliable though being very light.
 
Thanks to our constant research and development we are able to manufacture expanding air shafts at very competitive prices and satisfy varied customer requirements: from common standard shafts to the most complicated projects.

For the manufacture of our products our factory relies on the precision provided by modern high technology CNC machinery and the expertise of qualified technicians.
