- 11. The device as defined in claim 1 including brake means to arrest rotational movement of said frame when rotational movement of said spindle is discontinued.
- 12. The device as defined in claim 11 wherein said brake means includes a plate secured to said spindle, adjacent to and beneath bottom ends of said first and second legs, for rotational movement with said spindle, and means extending upwardly from said plate to engage a flexible projection from said yarn guide frame to arrest rotational movement of said frame when rotational movement of said spindle is discontinued.
- 13. The device as defined in claim 12 wherein said flexible projection comprises a strip of a suitable flexible material, such as leather, secured to said frame, said strip extending into a path of movement of said upwardly extending means.
- 14. The device as defined in claim 13 wherein said upwardly extending means comprises a pair of diametrically opposed posts, secured to said plate.
- 15. The process of twisting and winding material to make a yarn package in a continuous operation comprising the steps of:
- (a) delivering the material to be twisted and wound on a package;
- (b) guiding the material which is delivered to a point on a predetermined straight path;
- (c) twisting the material about the straight path at a first fixed station, and,
- (d) simultaneously winding the material about the straight path on a bobbin to make a yarn package at a fixed second station at a predetermined location; and
- (e) axially distributing the twisted material onto the bobbin after the twisting step utilizing a substantially free spinning twisted yarn guide rotatable about the straight path.
- 16. The process as set forth in claim 15 including the step of maintaining a predetermined tension on the material between said point on a predetermined straight line and said first station.
- 17. A product comprising a yarn package manufactured in accordance with the process set forth in claim 16.
- 18. The process as set forth in claim 15 wherein said first station is fixed and said step of distributing the twisted material is performed between said first fixed station and said second fixed station.
- 19. The process as set forth in claim 15 wherein the step of distributing the twisted material comprises the step of feeding the material tangentially onto the bobbin on which the package is being formed and maintaining pressure on the exterior surface of the convulsions on the bobbin.
- 20. The process as set forth in claim 15 wherein the twisting and winding steps are performed at substantially the same revolutions per minute.
- 21. The process as set forth in claim 15 wherein the step of delivering material is performed at a fixed station.
- 22. A product comprising a yarn package manufactured in accordance with the process set forth in claim 15.
- 23. A twisting and winding machine as set forth in claim 1 comprising an artificial rotatable bobbin at said fixed twisting station comprising a rotatable tube having a radially facing opening.
- 24. A twisting and winding machine for making a package of twisted multi-strand material, the machine including driven roller means to deliver the strand material to be twisted and wound on a package, and said machine including a rotatable spindle at a station and upon which a package is to be formed and means to drive the spindle, a bobbin on the spindle,
- a yarn twisting guide frame between the means to deliver and the station, said frame having a portion in engagement with the surface of the package being formed at all times in operation,
- tensioning means between the means to deliver and the station for maintaining a predetermined and preselected tension on the material while it travels through the machine between the means to deliver and the station,
- means to support the yarn guide frame for substantially free spinning coaxial with the spindle and circumferentially around said spindle and including means to axially move the yarn guide frame relative to the spindle, said yarn guide frame comprising means to guide the material onto the surface of the package substantially tangentially of said surface, and
- arresting means to control relative rotation of the free spinning yarn guide frame in relation to the rotation of the spindle when the angular velocity of the spindle is changed so that the angular velocity of the yarn guide frame does not exceed the angular velocity of the bobbin.
- 25. The device as set forth in claim 24 wherein said bobbin has an upper end face of a size less than the size of the package to be formed to accommodate unwinding of the material from the package.
- 26. The device as set forth in claim 25 wherein the bobbin is cylindrical.
- 27. The machine as set forth in claim 25 wherein the bobbin is cone-shaped.
- 28. The machine as set forth in claim 24 wherein said tensioning means comprises a traveler means.
- 29. The process of making a yarn package from material on a machine to form the package in a continuous operation, said process comprising the steps of:
- (a) delivering the material to be twisted and wound to a point of the machine;
- (b) simultaneously (1) twisting, (2) winding, and (3) axially distributing the material onto a driven rotatable bobbin utilizing a substantially free spinning yarn guide, said bobbin being at a station spaced from said point,
- (c) said step of distributing including guiding the material onto the surface of the package being formed by a portion of the yarn guide which is at all times in operation in engagement with the surface of the package being formed,
- (d) applying a predetermined tension at all times to the material when it is between the point and the station and while the package is being formed,
- (e) limiting at all times in operation the relative rotation of the free spinning yarn guide in relation to the rotation of the driven spindle by an arresting means so that whenever the angular velocity of the spindle is reduced, the rotation of the yarn guide frame is also reduced.
- 30. A product comprising a yarn guide package manufactured in accordance with the process as set forth in claim 29.
