Corrugated Board Liner and Medium Preheater

Corrugated Board Liner and Medium Preheater

A corrugated cardboard producing machine has a preheater for heating a corrugated cardboard sheet of original paper or single face type corrugatd cardboard sheet in each of various processing stages for producing a corrugated cardboard by bonding a liner paper onto a corrugated central core paper. The preheater is provided with a lap amount adjusting tool whose insertion amount between a circumference of a roll of the preheater and the original paper or the single face type corrugated cardboard is adjustable. The lap amount adjusting tool is movable along the circumference of the roll of the preheater.The multiple corrugated cardboard preheater offers a drying and heating solution for liner paper and corrugated paperboard in order to control their temperature and humidity.

The Infusion Preheater is designed to increase productivity and provide a solution to many runnability problems resulting from insufficient heat transfer. The preheater package is compact and easily installed.
The heating element consists of a stationary 20” diameter shell which is heated by high pressure and low pressure superheated steam.
Liner passes over the heated shell surface in a frictionless manner and is heated by the hot steam film. The amount of heat tranferred is essentially independent of web tension and the maximum paper temperature achieved is around 212° F. even at low speeds. Further, the paper mositure remains essentially the same throughout this heating phase.
