Fast Precise Hot Melt Turf Gluing System

Labor is one of the highest costs facing turf/sports field assembly companies. To minimize the amount of time need to assemble the seams of a sports field the hot melt machinery must be taken into account.

The standard hot melt systems used for on-site turf seam gluing applications are typically small 120 VAC systems with small gear pumps. These systems have insufficient melt rate and pump capacity for most applications and can dramatically increase the field assembly time.

Turf assembly companies require that high volumes of bituminous asphalic black hot melt are quickly applied to four inch tape or seams with coating thicknesses of .005″. This equates to approximately 10 lbs. of hot melt for every 100 feet of gluing.

For this application a 240 VAC 50 lb. hot melt tank (3500 watt, 240 VAC single phase) is needed with 1-2 lb per minute pump, 16′ abrasion resistant hose, High Flow handgun with .055 nozzle tip. Dual orifice nozzles can be added to the gun for single stroke gluing or a 2′ wand can be attached to the gun with a heated holster for the wand mounted on the cart.

For additional gluing convenience the system should be mounted on a wide footprint cart with a boom, hose cradle and tool balancer.

Winery Box Gluing with Hot Melt

Most small to midsized wineries do their own packaging. They erect and glue wine box bottoms, insert the filled bottles of wine and glue the tops of these boxes.

The most time consuming portion of the packaging process is the erecting of the wine box and the sealing of the box bottom. When gluing the bottom both liquid adhesives and hot melt adhesives are used. Typically the box is opened, the minor flaps folded in, the adhesive applied, the major flaps folded over the minor flaps and the box flipped over and compressed from the inside.

This process is very time consuming and tedious especially when using white or water based glue. Because this is so labor intensive it is not considered ergonomically correct package assembly. Fortunately, this problem can be easily addressed.

We recommend wineries purchase or build the correct box erector. This consists in its most basic form of a high volume hot melt system, box mandrel and tool balancer to hold the hot melt handgun. With a properly sized mandrel and box stop on the mandrel post, the box can be squared and the flaps glued in two quick steps. Slide the box over the box mandrel, fold the flaps, apply the hot melt, compress the flaps, pull the box off the mandrel and repeat. The hot melt gun should be properly “tool balanced” for easy use.

This system and will allow operators to easily make quality packaging at a much higher rate with less fatigue. The typical hot melt cost per box bottom is one cent.

Gluing the top of the case with hot melt is much easier and it requires half the adhesive quantity.

The Nordson Mini-Squirt is a quality hot melt gun with internal melt reservoir and high volume piston pump. The Nordson Mini Squirt melts hot melt adhesive in chip form and applies the hot melt to substrates in bead form through a check valve nozzle tip. The use of a Nordson Mini Squirt is a quality upgrade from hot melt stick guns as it will process a much wider range of low cost hot melts and allow for much faster application of this hot melt.

Please note that the Nordson specification sheet regarding this tool is incorrect as the gun holds approximately three ounces or 80 grams of molten hot melt and not the 7 ounces or 198 grams that Nordson claims. Also, users should be made aware that 15 minutes is an insufficient amount of time for the gun to heat prior to use. Operators should wait a full 20 minutes for this gun to properly heat the hot melt.

Finally, because the gun has very good output capability, hot melt can be used far faster than the gun can melt the adhesive. Consider a premelt tank from Glue Machinery Corporation to supply the Nordson Mini Squirt hot melt handgun with molten adhesive.

POP Display Hot Melt Gluers

There are many methods to apply hot melt adhesive for Point of Purchase (POP) display assembly.

The most common hot melt application methods in POP display assembly are the hot melt stick gun and the bulk hot melt tank with flexible hose and heated handgun. Hot melt stick guns are inexpensive and lightweight. Most hot melt stick guns have a very limited output rate which can slow production and affect product quality because of incomplete bonds on larger displays. Hot melt in stick form is typically considered very expensive starting at approximately twice the price of bulk hot melt. Finally, stick guns tend to fail quickly in industrial applications and are very difficult to rebuild.

The hot melt tanks, with flexible heated hose and guns, offer high melt rate and output rates and are needed primarily for the production of high quantities of large displays. They can melt a wide range of bulk hot melt quickly and allow for the fast application of this hot melt. These systems can be very expensive - typically starting at about $3000 for one tank, hose and gun. This system set up for smaller applications can limit the range and speed of motion and slow production. Support booms with tool balancers are very good components to employ with these systems.

Other systems successfully used for POP display gluing that offer distinct advantages over the stick guns and bulk tank systems are as follows:

Self contained bulk hot melt handguns with melt tank in the gun that process low cost chip hot melt and allow for similar simplicity and ergonomics of the stick gun. While being heavier than the stick guns - these guns can offer much faster instantaneous output than stick guns. The melt rate of these guns can be supplemented with gravity melt tanks
and melt tanks with manual piston pumps.

Roll Coaters with small reservoirs that process low cost chip hot melt can offer total simplicity in hot melt application. Operators simply manipulate a substrate over the wheel quickly for overall hot melt coverage and attach the component into a display.

Bench mounted systems with reservoirs that process low cost chip hot melt can also apply to substrates that are moved under the nozzle. These components are then attached to the display.

Finally, bulk systems with automatic applicators can cycle precise patterns on stationary or moving substrates with total accuracy and speed. Companies should consider these systems for very large jobs where quality product must be manufactured very quickly.

Glue Trap Adhesive Machinery

One of the most effective methods of pest control is the use of glue traps. Glue traps are available as Glue trays or Glue Boards.

Glue trays are filled with pressure sensitive adhesive that forms a thick pool of adhesive up to an 1/8″ thick. Glue boards are coated with .020 to .050″ thick hot melt adhesive and a polyisobutylene adhesive.

Typically Glue trays are used for rats and mice- while glue boards are used for mice, insects, snakes and scorpions.

Very often the hot melt applicators/guns used to apply high temperature polyamides for splices in roofing plants are completely insufficient.

They offer minimal melt rate in the heated pressure tube. They offer minimal output rates as they are only pressurized with air to a maximum of 60 psi. The temperatures are set too high to compensate for their limited melt capacity and they degrade the adhesive.

This affects the bond strength of the adhesive. This type of applicator is also breaking down constantly. Finally, it requires regular filling - exposing operators to high temperature adhesive.

Hot Melt Drum Unloaders- Why use this equipment?

The use of a drum unloader can offer the following benefits:

1. Reduces the operator handling of the adhesive -For 100 lb per hour consumption operators will spend a total of 10 minutes every five hours removing and inserting a drum versus 5 minutes every hour for the manual filling of 100 lbs from four 25lb. boxes or 2 50 lb. boxes.

2. Reduces operator liability -Potential contact with molten adhesive will be minimized

3. Reduces fuming of adhesive -This improves the plant air quality.

4. Cleaner manufacturing plant -Residuals from adhesive fuming do not build up on all surfaces.
