BRIEF SUMMARY
DESCRIPTION
TECHNICAL FIELD
The present invention relates to a method and an apparatus for winding a linear material.
BACKGROUND ART
The term "linear material" as used herein and in the appended claims is to be understood to mean any such materials as vegetable fiber, animal fiber, mineral fiber, synthetic fiber, metal wire, and the like. In the manufacture of composite pipe material, bar material, and plate material, it has often been the practice heretofore to wind a linear material around a core bar, to impregnate the winding of the linear material with such material as synthetic resin, cement, molten metal, or the like, and to allow such material to harden.
In the heretofore employed winding process, the linear material was wound around the core bar either by rotating the core bar while fixing a reel on which the linear material was wound or by moving the reel about the fixed core bar. However, the conventional winding process described above had serious disadvantages such that:
(1) It was difficult to enlarge the equipment because either the reel or the core bar had to be rotated or moved about;
(2) A continuous operation over a long time was difficult because exchange of the reel and extension of the core bar were necessary;
(3) It was difficult to wind a number of linear materials simultaneously; and
(4) Since the rotating and moving means was relatively complicated in construction and large in size, it was difficult to add thereto apparatuses to perform other working processes simultaneously.
DISCLOSURE OF THE INVENTION
An object of the present invention is to remove the disadvantages of the conventional winding process and to provide a winding method and an apparatus therefor, which are economical and efficient.
The winding method according to the present invention comprises the steps of inserting a core bar through a winding drum and a winding disk for a coaxial and relative movement therewith; disposing a reel with a linear material wound therearound at a predetermined position; fixing a leading end of the linear material payed out from said reel at an arbitrary position on said core bar through a guide hole of said winding disk; rotating said winding disk in a first direction while moving said core bar in a predetermined direction, thereby winding the linear material around said core bar while winding the linear material around said winding drum; after a predetermined quantity of the linear material has been wound, binding a terminal end of the winding of the linear material on said core bar to fix it thereon; after said binding and fixing, rotating said winding disk in a second direction which is opposite to said first direction while moving said core bar in a predetermined direction, thereby winding the linear material around said core bar while unwinding the winding around the outer peripheral surface of said winding drum and rewinding it; after a predetermined quantity of the linear material has been wound, binding securely the terminal end of the winding of the linear material around said core bar; and repeating the winding and the secure binding of the linear material around said core bar at predetermined times.
The winding apparatus according to the present invention comprises a reel disposed at a predetermined position and wound therearound with a linear material; an elongated core bar of a predetermined sectional shape; a driving mechanism for moving said core bar in the longitudinal direction thereof at a predetermined speed; a winding disk supported coaxially and relatively movably with said core bar and having at least one guide hole; a driving mechanism for rotating said winding disk alternately in opposite directions with a predetermined period and at a predetermined speed; a winding drum disposed upstream of and adjacent to said winding disk with respect to the direction of movement of said core bar and supported coaxially and relatively movably with said core bar; and a binder disposed downstream of and adjacent to said winding disk with respect to the direction of mov
