Corrugating Machine

Corrugation machines are used to manufacture corrugated cardboards, which are used for corrugated packaging. They are economic, light, robust, recyclable, and do versatile form of packaging. Corrugating machines are used for manufacturing corrugated cardboards of various types and usages.

Corrugating machines are vastly used in the filter machine manufacturing. They allow the filter manufacturers to achieve optimum media performance.

What is Corrugation?
Corrugation is a technique, which is used to apply wave shapes, or ridges in particular sheets and cardboards. The sheet of material is softened by steam, then this material is sandwiched between flat sheets of material to form corrugated fiberboard. These corrugated cardboards are used for manufacturing boxes or various packaging. After the various layers of the corrugated cardboard have been glued to each other, the cardboard is sent through a heated plate heating zone and then through a cooling zone.


Formation of Corrugated Cardboards
The simple cardboard is put into the corrugating machine by looped corrugating belts. The friction between the cardboard and the outer surface of the closed loop corrugating belt ensures the fed of the cardboard in the corrugating machine. All corrugating machines require a high friction coefficient between the corrugating belts and the cardboard. The different versions of corrugating machines have different modes of feeding the cardboard through the heating zones. Some of the modes are described below:

• First type of corrugating machines: Pressing rollers presses the corrugating belt, on which the cardboard rests, against the heating plates. It exerts a pressure sufficient enough to ensure the feeding of the cardboard, in addition to the contact with the heated plates.
  
  
• Second type of machines: Instead of pressing rollers, air cushions are used to press the corrugating belt which feeds the cardboard in the heating zone.
  
  
• Third type of machines: To fed the cardboards, no corrugating belt is required in the heating zone. The cardboard is inserted through the heating zone by a pair of belts arranged in the cooling zone.

Use of Corrugating Machines
Corrugating machines are mainly used for corrugating varieties of materials. They are used for corrugating materials like:

• Papers
• Pipes
• Plastic Extrusions
• Cardboards

Industries
They are used in different types of industries, like

• Filter Machine Industry
• Agriculture Industry
• Automotive Industry
• Construction Industry

Paper Corrugating Machine: The paper corrugating machine is used to corrugate papers. Various types and qualities of papers for different purposes are corrugated with the help of this machine. The machine is highly efficient in production and easy in maintenance. The machine has minutely finished flute rolls, which are fixed on roller bearings. The flute roll is set from one side only. A motor is used to keep the gum rolls rotating for agitation of the gum, and the gum unit is disengaged from the flute rolls. A steam shower is used to provide the perfect formation of the flutes. The paper corrugating machine is available in four different models.

• Single Face: One medium is glued to one flat sheet of liner-board.
• Single Wall: It is also known as Double Face. The medium is between two sheets of liner-board.
• Double Wall: Three sheets of liner-board with two mediums in between.
• Triple Wall: Four sheets of liner-board with three mediums in between.
