Service Bulletin: SB 050.1
Subject: Glue Seal — 1st Bottom Heat Seal Accessories
All combination heat and glue seal machines have been supplied with a heat ring assembly used with heat tooling on the first bottom station. It has been found advantageous to use the tooling heated ring design for glue sealed cups as well as heat seal. The use of heat around the outside bottom seam area aids adhesive bonding, just as heated seam clamps are used for this purpose.
It is recommended that all glue seal toolin be used with the first bottom heat seal accessory assembly. A tooling heated ring insert should be reodered specifying the cup drawing number and size. Reference this Service Bulletin number.
