In the process of producing felt, blanket pressing is a very important process, which will use the equipment of blanket pressing machine. Let's take a look at it in detail.

Felt is also known as blank shaping. According to different uses and specifications of felt, according to process design, the loose wool mesh under the influence of rubbing force, friction force, moisture and steam exerted on the upper and lower pressing plates makes the blank preliminary felting, and produces a certain thickness, specific gravity, a certain size of blank, creating good conditions for further shrinkage in the next process. Some tapestry press lifting devices are mounted on the gantry of the tapestry press. When the blank is pressed, the upper pressing plate can be pulled up and down parallel to the lower pressing plate. In order to prevent accidents, the upper pressure plate will not slide automatically after lifting.

The self-locking of worm and worm must be considered in the design of traction worm wheel and worm, that is, the angle of worm lift is larger than the friction angle between worm and worm, and for finishing worm and worm, the self-locking of rolling bearing can be used.
