Definitions

• the invention relates to a machine for winding tape on a package core, for example tapes comprised of carbon fibers.
• the primary objective of the invention is to provide a machine for accurately winding fragile tapes with little or no damage to the material.
• the machine 10_ for winding tape 11 on a package core 18_ generally com ⁇ prises: a supporting framework 14_ having a component at one end thereof supporting a fixed guide roll 12_ having its principal axis normal to the tape 11 at a distance above the supporting framework 14_; a steering frame 19. pivotally mounted on the supporting framework 14_, the pivot bearing 2! located such that the end of the steering frame 1 ⁇ is moveable in an arc parallel to the axis of the package core 1_8_; a first steering roll 1 mounted on the steering frame 19_ directly above the pivot bearing 20_, the relative positions of the fixed guide roll 12_, the first steering roll 16.
• a rotatable package core 18_ located proximate to the second steering roll 17.
• a winder cam machanism 21 ; a cam follower connection 22_; slide bars 23 or linear bearings mounted on the steering frame 19 communicating with the cam follower connection 2_; winder drive means 2 _ for rotating the package core 1 ; a roller bail 2j having its principal axis parallel to the principal axis of the package core 18_ and in contact with the outer surface of the core 1 or tape 3 being wound on the core 18.
• tape width restricting pins 2j are mounted on the steering frame 1J3. Between the first steering roll S and second steering roll 17 at a location more proximate to the second steering roll 17 at a position of at least 60% of the distance between the steering rolls 16 and 17. Preferably, the pins 6_ are mounted directly proximate to the second steering roll 17.
• An edge guide sensor 27_ may be mounted in front of and proximate to the fixed guide roll 12_ to assure that the tape JUL is maintained in a fixed position.
• a tape composed of carbon filaments LI having a nominal width of 0.75 in. (0.19 cm) was fed into the winder 10 under controlled speed, tension, and position with the speed of the winder being controlled in a conventional manner to match the speed of the tape LI.
• a position sensor 21_ was located close to a fixed guide roll 12_ so as to assure that the tape 11. was maintained in a fixed position with respect to the winder.
• the tape was threaded over the fixed guide roll L2, which is mounted on a frame ]L4_, under the first steering roll 16_, over a second steering roll L7 and on to the package core or tube 18.
• the steering rolls 16. and L7 are mounted on a steering frame 1 ⁇ which oscillates about a pivot bearing 2 located under the first steering roll 16_.
• a cam 21. of a conventional winder type was driven in a conventional manner from the winder drive mechanism 24 as used to rotate the package core 1_.
• a cam follower is connected through a cam follower connection 22_ to slide bars 23_.
• the frame was thereby made to oscillate about the pivot bearing 20. as the cam 21_ rotated.
• the second steering roll 17_ moved in a las -e radius arc in a plane parallel to the axis of the package core 18_.
• the second steering roll L7 is positioned close to the surface of the package core 18..
• the close separation between the second steering roll L7 and the package surface was main- tained by the conventional technique in which the pressure of a roller bail 25 against the surface of the package gradually increased the separation between the package core 18. and the second steering roll L7 as fiber collected on the core 18.
• This mechanism provides a means for moving a fragile tape in a side-to-side motion without damaging the tape.
• the only distorting motion imposed by this apparatus is a twisting action between the fix roll 1 and the first steering roll 16_.
• the degree of twist is not sufficient to damage the carbon fiber tape 11.
