Claims
- 1. A winder for directly drawing glass fiber from an orifice plate to form a precision wound package, said winder comprising: a traverse mounted in a fixed position, said traverse having a guide disposed for back and forth movement thereacross in a generally rectilinear path; a spindle disposed in parallel relationship to the rectilinear path of the guide; means mounting the spindle for rectilinear movement toward and away from the traverse while maintaining the relative parallel relationship of the spindle with the rectilinear path of the guide, a sensor to sense the distance between the traverse and the peripheral surface of a package of windings on the spindle; motion imparting means coupled to the spindle to move the spindle away from the traverse, said motion imparting means being operatively associated with the sensor to maintain a substantially constant distance between the traverse and the peripheral surface of windings on the spindle; a D.C. motor coupled in driving engagement with the spindle; a D.C. speed control electrically coupled to the D.C. motor to selectively vary the speed of the motor; a linear response speed command potentiometer, wherein the resistance change for each equal increment of potentiometer adjustment is the same, electrically coupled to the D.C. speed control; a cam carried by the means mounting the spindle for rectilinear movement, said cam being disposed for movement with said means and having an operating surface configured so as to provide an unequal increment of movement of the potentiometer for each equal increment of package diameter growth to maintain drawing speed constant as the package grows; a follower engaged with the operating surface of the cam for movement responsive thereto as the mounting means for the spindle moves rectilinearly in response to package growth; and means coupling the follower to the potentiometer to adjust the potentiometer in response to the movement of the follower.
- 2. A winder for directly drawing glass fiber from an orifice plate to form a precision wound package, said winder comprising: a spindle disposed to draw fiber from the orifice plate; a traverse disposed to guide the fiber back and forth across the spindle to form a package thereon; means mounting the spindle and traverse for movement relative to one another to maintain a substantially constant spaced relationship between the traverse and a package on the spindle; a D.C. motor coupled in driving engagement with the spindle; a D.C. speed control electrically coupled to the motor to selectively vary the speed of the motor; a linear response speed command potentiometer for the speed control, wherein the resistance change for each equal increment of potentiometer adjustment is the same; a cam and follower disposed for movement relative to one another in response to relative movement of the spindle and traverse as a package grows, said cam having a follower operating surface configured so as to provide an unequal increment of movement of the potentiometer for each equal increment as package diameter growth to maintain drawing speed constant as the package grows; and means coupling the follower to the potentiometer to adjust the potentiometer in response to growth of the package whereby relative movement of the cam and follower in response to package growth maintains drawing speed constant.
- 3. A winder for forming a wound package from an elongate strand, said winder comprising; a spindle disposed to draw the strand into a wound package; a traverse disposed to guide the strand back and forth across the spindle; means mounting the spindle and traverse for movement relative to one another to maintain a substantially constant spaced relationship between the traverse and a package on the spindle; a D.C. motor coupled in driving engagement with the spindle; a D.C. speed control electrically coupled to the motor to selectively vary the speed of the motor; a linear response speed command potentiometer for the speed control, wherein the resistance change for each equal increment of potentiometer adjustment is the same; a cam and follower disposed for movement relative to one another in response to relative movement of the spindle and traverse as a package grows, said cam having a follower operating surface configured so as to provide an unequal increment of movement of potentiometer for each equal increment of package diameter growth to maintain drawing speed constant as the package grows; and means coupling the follower to the potentiometer to adjust the potentiometer in response to growth of the package whereby relative movement of the cam and the follower in response to package growth maintains drawing speed constant.
