Abstract: The dynamic torque and the loss of stretching force for coilers have been considered by designer to satisfy coiling by constant-stretching force. It must be calculated exactly especially by the use of Computer Control. In this paper, formula of calculation of dynamic torque and loss of stretching force for coilers is established by using two examples.
