Claims

[Scope of utility model registration request]

A detection bar is provided in parallel with the original fabric that moves up and down in response to the amount of drooping of the fabric released from the original fabric, and a variable resistor whose resistance value changes depending on the vertical displacement of the detection bar is provided. A speed control board having a circuit that gives a speed change signal to the variable speed motor by a change in the resistance value of the resistor is provided, the variable resistor and the speed control board are connected, and the speed control board and the variable speed motor are connected. A fabric spreading machine having a fabric unraveling speed adjustment device.
