Roll Coaters

All Pax Roller Coater models include the following features:

• Lubrication is fed through the center of each roll.
• Ability to Provide Different Amounts of Lubricant to Upper & Lower Rolls
• Slim Design
• Increased Roll Life
  • Polyethylene spacers, limit the amount of compression on the felt material, which minimizes the material compression.
• Rebuildable Rolls

Goal

The goal of in-die lubrication is to maximize both production and die life by consistently applying the exact amount of lubricant that is required, exactly where it is required. For many applications, this will result in:

• Extended die life, typically by reducing heat.
• Increased production rates
• Reduced quality issues
• Reduced lubricant use

Application Methods

The most typical method of applying in-die lubrication is via magnetic-based spray assemblies, (MBSA). The main advantage of these assemblies is their flexibility, they can be placed pretty much anywhere on the die and can be used on most dies. The main disadvantage of magnetic-based spray assemblies is that they are flexible, which means that they will be set up slightly differently each time they are installed on a specific die, which minimizes consistency.

To eliminate the lack of consistency that can result from using magnetic-based spray assemblies, many customers will utilize bracket mount spray assemblies, (BMSA). These nozzle assemblies are bolted directly onto each die. During the installation process, the position and rotation of both the bracket and the nozzle(s) attached to the bracket are adjusted until the lube is applied exactly where it is required. The assembly is then fastened in place to assure that this spray location is maintained.

When it is not feasible to spray lube to the required area via either MBSA or BMSA, it may be possible to either embed nozzles into the tooling or pump lubricant onto, around or through the die punches. This is typically more feasible if it is done when the tooling is initially designed but, in some instances, it is possible to embed nozzles into existing tooling.

Implementation Tips:

• If in-die lubrication methods are to be implemented, it is typically best to start with just one die and to start with either a die that is underperforming or a new die that has not yet been built.
• When feasible, it is typically more advantageous to apply the lubricant to the tooling as opposed to the material. This assures that the lube is applied exactly where required and it can also help to cool the tool.
• Spray nozzles should be positioned as close to the targeted area as possible. This allows the spray system to be run at lower pressure, which will allow the lubricant to better adhere to the targeted area.
• Keep lubrication line length as short as possible and minimize restrictions. This is especially critical for thicker lubricants.

Pre-Pressurized Spray Assemblies

Magnetic Base Spray Assembly for Pre-Pressurized Systems

The magnetic base provides flexibility for positioning the assembly as required and the rigid clamping and spraying assembly assure that the unit remains where it is positioned. The assembly includes a 250 lb. pull magnet with steel post, clamp assembly, stainless steel tube, female nozzle assembly with choice of spray tip, quick connect male plug, and 8′ of ¼ tubing.

Flextube Magnetic Base Spray Assembly for Pre-Pressurized Systems

The flextube assembly provides ultimate flexibility for the positioning of the spray nozzle, however, it can also be more easily moved out of position than either the magnetic base assembly or the bracket mount assembly. One flextube assembly includes a 250 lb. magnet w/ bracket and release lever, flextube segments, 8’ of ¼” tubing, tubing nozzle assembly, and male plug.

Spray Line Assemblies for Pre-Pressurized Systems

This 8’ long, ¼” spray line has a quick connect male plug on one end, (to connect to the Pax distribution pumps), and a spray nozzle (including nozzle body, check valve, tip retainer, and choice of spray tip) on the other end. The customer is responsible for determining the mounting arrangement.

Pax bracket assemblies are the ideal way of permanently mounting spray assemblies. The spray angle can be adjusted by simply rotating either the nozzle and/or the bracket and the vertical height of the nozzle can be adjusted by moving the nozzle within the bracket slot. Once the position of the assembly is finalized, it is locked in place by tightening the bracket screws.

Assemblies include stainless steel bracket, spray nozzle, choice of spray tip, tip retainer, check valve, 1/8″ male elbow, mounting screw, and stainless steel washer. (Requires ¼-20 tapped holes for mounting).

Multi-Nozzle Bracket Mount Assembly for Pre-Pressurized Systems

Includes stainless steel bracket, a mounting screw, a stainless-steel washer, and two of each of the following: spray nozzle, choice of spray tip retainer, check valve, and 1/8″ male elbow. (Requires ¼-20 tapped holes for mounting).

Spray Tips (contact Pax for additional tip options)

Note: A low viscosity (Tellus #10) lubricant was used to obtain the pattern sizes described. The tips were placed in the vertical position and held 6″ from the surface with an air pressure setting on the FRL of 35 psi. Pattern sizes may vary depending on lubricant viscosity and air pressure setting.

Pre-Pressurized Spray Assemblies

Magnetic Base Spray Assembly with Standard Nozzle (06-3112-31)

The magnetic base provides flexibility for positioning the assembly as required and the rigid clamping and spraying assembly assures that the unit remains where it is positioned. The assembly includes a 250 lb. pull magnet with steel post, clamp assembly, stainless steel tube, female nozzle assembly with choice of spray tip, quick connect male plug, and 8′ of ¼” hard, (nylon), tubing.

Flextube Magnetic Base Spray with Standard Nozzle (06-3016-30)

The flextube assembly provides ultimate flexibility for the positioning of the spray nozzle, however, it can also be more easily moved out of position than either the magnetic base assembly or the bracket mount assembly.
