Require complete description of this product it's name used in paper corrugated board and box making machines

This product is a Pneumatic Diaphragm Actuator (often referred to as a Pneumatic Brake Unit or Brake Cylinder) specifically designed for tension control in the corrugated board industry.

It is a critical component used to manage the "web tension" of the paper as it is pulled through the corrugator.

Technical Name & Identification

Common Industry Name: Pneumatic Brake Actuator / Diaphragm Tension Brake.

Machine Application: Used on the Mill Roll Stand (the part of the machine that holds the large paper rolls) and the Single Facer or Double Backer units.

Detailed Product Description

The unit consists of several key parts visible in your image:

Threaded Adjustment Stem (Top): This allows for the manual adjustment of the initial tension or stroke length.

Locking Nuts: The two large hex nuts on the stem are used to secure the position once the tension is set, preventing it from loosening due to machine vibration.

Conical Housing: This cast metal dome houses a flexible rubber diaphragm and a heavy-duty internal return spring.

Flange & Bolts: The series of bolts around the perimeter hold the two halves of the housing together, sandwiching the diaphragm to create an airtight seal.

Air Port (Bottom/Side): While not fully visible, there is an inlet where compressed air enters to push the internal piston.

How it Works in Corrugated Box Making

In the corrugated industry, maintaining consistent tension is vital. If the paper is too loose, it wrinkles; if it's too tight, it snaps.

Tension Control: Compressed air is fed into this unit. The air pressure pushes the internal diaphragm, which in turn pushes a rod against a Brake Disc or Brake Pad assembly on the paper roll shaft.

Friction Management: By increasing or decreasing the air pressure to this actuator, the machine operator (or an automated system) can precisely control how much friction is applied to the rotating paper roll.

Constant Feed: As the paper roll gets smaller and lighter, the brake pressure is gradually reduced to keep the "pull" of the paper consistent.

This industrial brake pads / friction blocks with metal backing plates. These are commonly used in industrial braking systems – not vehicle disc brakes, but heavy-duty machinery brakes.
