Core Gluing System

 

For over 3 years Spraymation has been promoting the use of a Slot Coater Applicator Head to extrude a thin film of cold adhesive onto the webs used for 2 ply spiral wound cores, eliminating typical “pot and roller” equipment. A number of users have now implemented this new technique. The Spraymation direct core glue application equipment, now in its third generation, is in operation 24/7, at numerous sites.

 

The Core Gluing System includes web supports which allow uniform coating at low web tension, and an active electronic servo controlled Web Guide System, providing +/-.005” (+/-.13mm) control. The Applicator Head mounting system has four independent adjustments to obtain the optimum adhesive coating. The included Metering Pump Module, delivering precise amounts of adhesive, is a gear pump driven by an electric motor that is`

 

Special equipment is available for applications requiring the dispensing of heated adhesive, or for use with central adhesive distribution systems. In some instances, standard Test Stand Equipment is available for “trial and evaluation” purposes.

 

 

 


The advantages of extruding a ribbon of adhesive onto the core stock are simple:

  1.  Often the roller that is presently used is the speed limiting component. Extrusion does not have this limitation.

  2. Amount of adhesive added on can be closely controlled and monitored. Typical pot and rollers have no method to control how much adhesive is used.

  3. The adhesive supply is not contaminated with paper fibers. Often extra adhesive is used with pot and rollers, resulting in added expense.

  4. The amount of maintenance and clean up is greatly reduced.
