Description

[Brief explanation of drawings]

Figure 1 is a perspective view showing the state of winding of a band-shaped rubber string, Figure 2 is a sectional view showing the deformation of the outer part of the wound rubber string when the tension is too large, and Figure 3 is a conventional rubber string. It is a sectional view showing an example of a string winding device. 4 to 6 are views showing one embodiment of the present invention, and FIG. 4 is a front view showing the overall configuration;

Claims (1)

[Scope of utility model registration request] A winding shaft driven by a constant torque electric motor, a length measuring roller driven by a variable speed electric motor that grips and feeds the rubber string, and a supply roller having an independent drive source placed before the length measuring roller. A control means that detects the amount of slack in the rubber string between the supply roller and the length measuring roller to control the rotation of the supply roller, and a control means that detects the amount of rotation of the winding shaft or the length measuring roller and controls a constant torque for driving the winding shaft. A control means for controlling the voltage supplied to the electric motor and the rotation speed of the variable speed electric motor for driving the length measuring roller, and a control means for stopping the winding shaft and the length measuring roller when the rotation amount of the length measuring roller reaches a predetermined value. A winding device for a band-shaped rubber string, comprising:
