Headquartered in Varese, near Milan since 1947, Aletti was founded by machine tool mechanical designer Franco Aletti and his father Giovanni who was head of maintenance at the largest tannery in Varese. The first machine built by Aletti in 1947 was a 250 mm buffing machine, which, because of its performance and high quality, soon succeeded in establishing itself in Italy, making improvements to German imported machines. Fast forward 72 years and the unveiling of the first whole hide belt-buffing machine.

Downloadable PDF Extra complexity after Lear makes its move
Relationships in the automotive supply chain have always been interesting, not least for tanners, who usually sell to original equipment manufacturers (OEMs) but supply finished leather or cut parts to specialist tier-one suppliers of seats, steering wheels and other car interior components. In 2014, one of these specialist tier-ones, Lear Corporation, added extra complexity and extra tension to this panorama by acquiring a major, global automotive tanning group, Eagle Ottawa. This article examines Lear’s reasons for taking this step and offers a view of the likely reaction among other tanners and tier-ones, and among OEMs in the months and years following the deal.

Downloadable PDF Innovation in the beamhouse
The conventional sulfide/lime system for unhairing and as part of the fibre-opening process has been in its existing form for approximately 150 years. However, appropriate treatment is required to avoid considerable pollution, and this is at the expense of the tanner. Moreover, the presence of sulfide restricts the use of by-products, and limits the way that effluent treatment can be rationalised. A new process is very desirable, and a new technique has been investigated. This is outlined in this paper together with the potential advantages that might be gained by a sulfide-free unhairing system, and the route that must be followed if rationalised processing is to be achieved.

Management’s main concern is to make sure that stocks are ordered and delivered on time, but out in the backyard of the factory we are confronted with an aspect that is generally ignored — the “empties”.

Downloadable PDF Removing phospholipids from hides: Looking back on a “New perspective on wet processing”
The paper "New perspective on wet processing" was published in World Leather October/November 1993, in which the advantages offered by the removal of phospholipids were discussed. Given that the value of raw hides and leather selling prices - strongly influenced by area and quality - are so important to the tanner, perhaps it's time to re-evaluate this technology.

Downloadable PDF The milling drum – from blunt instrument to sophisticated process vessel
There are several areas in tannery machinery where the application of modern technology seems to have been an over-elaboration. The milling drum, however, is a real exception, where the application of modern sensors, control technology and automated handling has turned a blunt instrument into a sophisticated process vessel, capable of repeatedly reproducing subtle effects in the nature of the leather produced.

Downloadable PDF Automated handling in the finishing area
The finishing area has always seen the greatest requirement for labour in the tannery. The rising cost of labour in developed countries, and the increasing difficulty of finding workers prepared to do monotonous, repetitive manual work, have been the impetus for many years to seek automated handling solutions. Mechanical stackers have been around in primitive forms over twenty years, but how have they advanced?

Downloadable PDF The V-Fold belt filter press
The V-Fold filter was developed in Australia to dewater slurries and sludges generated during wastewater treatment so they can beremoved at lower cost, and in some cases used in compost. Its simple design and forgiving nature means little operator input is needed, even when the slurry composition varies.
