Hot Melt Coating Linerless Labels

Hot melt coating is now widely used to produce pressure sensitive labels. The traditional method of printing pre-manufactured label stock is now being attacked by printers who want to produce their own label stock in-line on the printing press. This can be achieved by adding a hot melt coating station onto the print press. The coating unit applies pressure sensitive hot melt adhesive or other types of hot melt adhesive only to the areas requiring adhesive. This means that the adhesive can be applied in stripes or patches. This can increase efficiency and also allow special products to be manufactured with, for example, print underneath the adhesive.

In the last five years there has been a growing trend to reducing packaging waste. As a result, there has been a growth in the use of linerless labels - when the labels are applied there is no liner to throw away. Universal Converting Equipment has worked with Universal Adhesive Systems and ITW Dynatec to develop a solution for this market. Special coating technology is used to apply up to 16 narrow stripes of adhesive onto materials up to 600mm wide. Fast change die design allows the coating pattern to be change in a matter of minutes whilst still achieving precise coat weights.

The Universal hot melt coating system can be built into existing equipment or supplied as a complete coating line with in-line silicone coating, slitting and turret rewinding. For the label printer, more of the product added value is in their hands and once the technology is installed it opens up the possibility of other new product areas. Hot melt coated linerless labels are now a significant part of the printed label market.

Computacore Laser Core Alignment Order

Since we started putting video of some of our products on YouTube we have started to recieve more enquiries. We had a potential customer find our Computacore laser core alignment system video. After the exchange of a few comments and then some emails, his boss has just place an order with us for a Computacore system to go onto a Titan SR6 slitter rewinder. The system should be installed at the end of next week. The wonders of new technology.

More details on this system can be found in earlier blogs or on our web site. We have a range of upgrade systems for converting machinery including slitting machines, slitter rewinders, winders, coating and laminating machines.

Converting Machinery Upgrades

Universal Converting Equipment has been involved in the design and manufacture of converting machinery for many years. Initially, Universal built drive and control panels for converting machinery. These control systems were sold to manufacturers of converting machinery and to end users to upgrade their existing machines. The typical converting machines were centre wind slitting machines, center surface slitter rewinders, surface driven slitters and winders, two drum winders, coating machines and laminating machines.

More recently, Universal moved into the manufacture of slitting machines, producing a high performance machine and a low cost machine, rewinding machines, hot melt coating machines and hot melt laminating machines.

The interest from our customers in upgrading machines has increased considerably in the last few months as budgets for new machines have been cut back. As a company, we have the expertise to take on a wide range of projects from small projects like adding a new guider or tension control systems, to new drive and control systems and then to a complete mechanical and electrical upgrade.

In recent weeks we have taken orders for drive and control upgrades for Titan slitting machines, Kampf slitting machines and a Dusenbery slitter rewinder. We have also fitted several core alignment systems in conjunction with new differential rewind shafts. As the cost is low compared to new converting machines, the payback is very fast - just what is needed when the economy has slowed down.

Two Drum Winder Upgrade

We have just installed a new drive and control system on a Cameron two drum winder. The base machine was over 30 years old but was very solidly built and the customer didn't want to scrap the machine. Installing the new drive and control system has made a huge difference to the performance and the safety of the machine. The machine will run at 1500m/min using closed loop control of tensions and rider roll pressure to ensure rolls of the correct density are produced every time.

A recipe system has improved consistency of product and a record of setting used for every set of rolls is saved within the system. At the same time the safety systems on the machine were upgraded to conform to the latest standards.

We have completed similar upgrades to two drum winders from Cameron, Jagenberg and Masson Scott machines. This is part of a range of drive and control upgrades we have for slitting machines used for slitting and rewinding paper, plastic films and other materials. The upgrades to machines from companies such as Titan, Atlas, Dusenbery, Cameron and several others complement to new slitter rewinders that we produce.

TS350 Turret Slitting Machine

We have a fully refurbished TS350 Turret slitting machine available for sale. It has been mechanically refurbished including new bearings and new roller coverings. A new drive system has been added with SSD drives. A new Siemens PLC controls the machine with a touch screen operator interface. A ConverterGuide 4 Digital guider has been fitted. This machine will outperform a lot of new machines. It has our latest ball lock differential shafts and our Computacore laser core alignment system making set up and changes very quick and easy.

The machine is 1300mm wide with a shafted unwind. Access to the knives is easy from the walkway between the unwind and the rewind. The machine has rotary shear knives and also razor slitting.

Computacore with razor and core positioning

Another video showing the core positioning system in action has been added to YouTube. This time it shows the system on one of our slitting machines. As well as indicating the correct position for the cores, it also shows the correct position for the razor blades. Setting up is so simple.

Budget Price Slitting Machine

Universal has launched a range of budget priced slitting machines under the name Universal X7. These machines are built to a budget price but they are not built cheaply. Prices start at £60,000 for a 1300mm wide machine with 610mm rewind diameter and a running speed of 300m/min. There are a range of options to add to the machine.
