ABSTRACT:
An apparatus for twisting and winding strand onto a rotating bobbin comprises a spindle and an open top pot both mounted for coincident rotation about a common axis. A lower portion of the spindle extends outside the pot and is journalled in a set of low friction bearings. The bobbin is provided with a pair of sleeve bearings so that the bobbin is rotatable about the spindle. On the inner wall of the pot, a strand hook is provided to guide strand material onto the rotating bobbin. During operation, a strand is continually supplied to the apparatus at a constant lineal rate as the spindle and pot are rotated by a first motor thereby imparting twist to the incoming strand. The strand hook is axially reciprocated to traverse the strand along the length of the bobbin so as to distribute the strand in successive layers thereon. A second motor, mounted inside the pot, rotates the bobbin relative to the pot for winding the strand. A sensing device, inserted into the incoming strand and above the pot, continuously monitors the actual operating tension in the strand. This information is transmitted in the form of a voltage signal to an electronic control circuit. The circuit compares the signal with a fixed voltage reference signal corresponding to a preselected, fixed tension level. The control circuit immediately corrects any deviation between actual tension and desired tension in the strand by adjusting the speed of the second motor so as to cause the bobbin to wind the strand at a different rate.
