Push Up Pleating Machines

The push-up pleating machines are a special type of pleating machines. They are an improved version of general pleating machines, capable of creating controllable and non-repeating pleated patterns in all types of materials.

In Filter Manufacturing Industry
Push-up pleating machines play an important role in the production of filter machines and have become one of the primary machineries used in this industry.

Working of the Push-Up Pleating Machines
The push-up pleating machines usually have a drum, which has several distinct rows about the circumference of the drum. Each and every drum row contains a multitude of pins. The drum is displaced vertically, during operation of the machine. As the drum is displaced, the pins start acting on the push-up rods which displace the concurring blade pairs.

The vertical displacement of the drum does not result in the displacement of the concurring blade pairs if no pin in the drum coincides with a push-up rod. The shift of the blade pairs results into creating a "reverse pleat" in the materials being pleated. On the other hand if a blade pair is not translated or displaced, then a result of that a "forward pleat" is formed. Therefore the row patterns are created by including and excluding the pins in a drum row.

Push-up pleating machines are operated and controlled mechanically. The position of the drum shifts as it rotates to the next sequential position after each displacement and return of the drum. It happens so that as the next subsequent drum displacement occurs, the next adjacent row of pins may act on the push-up rods. Thus the distribution of the pin positions in each drum row is responsible for creating the pleated patterns in the material.

The typical push-up pleating machines are capable of producing only pleated material having a repeating pattern. However modifications in the pattern produced by the pleating machine requires removal of the drum and rearrangement of the individual pins at different locations. Since the replacement of the drum is a very arduous and expensive operation, therefore, it discourages variation of the patterns produced.
