HM11-TB is an Automatic Hot-Melt Carton Sealer.

Automatic Hot Melt case sealer with side driven belts and manual dimensioning, suitable to seal the upper and lower parts of boxes of the same size coming from filling line. It doesn’t require the presence of an operator. The box coming from a filling station, with the bottom part sealed, is taken and driven through the driven belts inside the machine where injectors apply 4 strips of Hot Melt glue. The upper and lower flaps, after being folded, are kept in pressure by a suitable presser until the next box arrives. The Hot Melt sealer doesn’t require the presence of an operator except for the glue adjustments and feeding. It is equipped with an anti-accident guard with panels which prevents the operator from coming into contact with the moving parts or with high temperatures parts.
