The dies can be moved and slot depth adjusted easily. This machine is exclusively designed and manufactured for the pasting of corrugated sheets of different ply. Simple in design, strong in construction, easy to operate and is assured of faultless working during continuous operation. The rolls of the machine are smoothly finished to ensure even impression of the boards after lamination.
