Palamides Delta-Pro

Brian Sims unbundles the Delta-Pro series from Palamides. Automation is just one way to improve efficiencies with this particular range focusing on the bundling of post-press products

The Palamides Delta-Pro range boasts five models

Counted, bundled and firmly banded

In the environment we work in, manning and the utilization of manpower is one of the most difficult and time-consuming issues any production manager has to deal with. Labour costs are likely to be second from that of raw materials, so the deployment of staff needs to be effective and worthwhile.

Very often it is obvious where the savings in manpower can be made, but quite often where manual labour is taken for granted, the use of machinery can be overlooked. One such area is the stacking and bundling of post-press products.

Traditionally the output of a buckle folder or saddle stitcher is knocked up by hand and stacked accordingly in boxes or piles. The output aperture can also prove difficult for operators where back and manual handling concerns are becoming more and more relevant.

One company that has come up with a solution to this issue is Palamides and its range of automatic deliveries called delta. The smallest machine is the 502, there is a 703, 705, 705xs and the largest of all the machines, the 1005.

The delta automatic delivery can be moved into position on range of post-press equipment and can automate the process of bundling copy, blanks, magazines and a whole range of printed materials.

The automated delivery has an adjustable infeed tape system that can positioned be to the correct height for the delivery of say a saddle stitcher. The belts themselves can be positioned across the width of the delivery unit to correctly handle the product being processed. At this point, the unit can detect waste sheets and automatically eject them from the production line to avoid any waste going into the bundles and stack.

To maintain bundles of the most efficient height, there is a pressing unit that has a full width roller that will exert a load of up to 3,500kgs to ensure even the bulkiest product is pressed and processed to an optimum height. For cleaning and setting procedures, the pressing roller can be pneumatically opened so access to it is easy.

Once pressed, the product is passed through the automatic delivery unit and through the use of a series of tapes the product is dropped and set into a number of stacks. At this pre-determined point, the bundles are counted and are wrapped with a paper band to keep the bundle in shape.

The paper band is available in a number of widths but typically a band of 50mm is used to control the bundle. Once wrapped around the bundle the automatic delivery uses a system called electronic impulse welding (EIS) to join both ends. The use of EIS is to ensure the correct amount of pressure is maintained on the band to avoid breakage but to avoid damage to the product.

Once bundled and wrapped, the product is dropped down onto a delivery table and is pushed through to the buffer table where it is lifted onto a delivery platten that is at the optimal height for an operator.

The benefits of this unit are very obvious when you see it laid out next to a post-press machine but not so obvious as conventional practices overrides lateral thinking. You now have the product counted, bundled and firmly banded, making the final packaging of it simple and easy at a height that will not cause injury to an operator.

The other upside of using the delta automated delivery is the manpower needed for the bundling and counting process is now unnecessary and the stitcher or folder operator can easily complete all the tasks needed from feeder to boxing.

As for the layout of the equipment, there are four possibilities of layout giving both left and right-handed configurations.


Setting up of the equipment can be completed in a matter of minutes. No tools are needed, and the automated delivery jogging device can be set by the use of ergonomically designed lever type clamping mechanisms.

Setting up the equipment can take just a couple of minutes 

Dependent on the size of machine taken, a large number of configurations can be used on the delta automated delivery. One, two and up to five up production is possible over a range of sizes from widths of 60mm (when using the 705xs model) up to 1,100mm.

Banding is typically 50mm as previously discussed and materials for the banding can be either paper or plastic. It is also possible to use separation for multiple-up production by the use of different colour tapes.

The basic model is very well equipped and will cope with a wide scope of production, but should you need more options, the list for alternative additions to the delta automatic delivery is extensive.

Should you look to process small units, there is as specific version of the machine that can cope with the smaller width and length. Along with small size, packages with a smaller height down to three millimetres can also be accommodated with the optional extra.

Anti-static devices, air blast and a variable stacking device can be used for products that are more demanding than the normal run of the mill products.  Should cardboard be used as the base material, a cardboard package can be ordered which has all the pre-requisite equipment needed for feeding heavier materials.

Other clever options include bar code readers and a printer’s imprint reader which will allow for the reliable separation of individual book blocks for book on demand lines.

If production is at the higher end of the scope of the delta automatic delivery system, then an upgraded buffer table of up to 2.5m can be requested.

Any of the units available can be hooked up to a large number of manufacture’s equipment by the use of simple couplings. The automatic delivery can be easily moved from one device to another and set up ready for production in minutes.

These little pieces of equipment are very understated in the press room but can contribute significantly to efficient production
