hot melt adhesive, the temperature of base material, the temperature of edge sealing material and the temperature of working environment (the workshop where the edge sealing machine is located) pur hot melt glue are very important edge sealing parameters. In the automatic edge sealing machine due to hot melt granule adhesive coated on the base material, the temperature is too low base material will make hot melt adhesive curing in advance, resulting in glue can stick on the base material, but not stick edge sealing material, the temperature of the base material is best kept above 20°C. The working temperature of edge packer will affect the curing speed of adhesive. The factory often appears the edge sealing problem in the low temperature season, the reason is that the curing speed of hot melt adhesive is accelerated at low temperature, and the effective bonding time is shortened. If the feed speed of the edge sealer cannot be changed (in most cases)
