principle
The principle of operation of the folding devices is based on the transformation of the rotational movement of the drive shaft into a linear movement of the folding carriage on a smooth shaft in two directions using the interaction of friction forces between the drive shaft and the collars of the ball bearing mechanism for switching the stroke of the folding carriage.
By changing the angle of the on-clone of ball-clip holders, the speed of movement of the folding carriage on the smooth shaft is regulated.
