Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
232 words
A winding method comprising 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; binding, after a predetermined quantity of the linear material has been wound, a terminal end of the winding of the linear material on said core bar to fix it thereon; rotating, after said binding and fixing, 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 the core bar while unwinding and rewinding the linear material around the outer peripheral surface of said winding drum; binding, after a predetermined quantity of the linear material has been wound, the terminal end of the winding of the linear material securely around said core bar; and repeating the winding and secure binding of the linear material around said core bar a predetermined times.

Dependent Claim

Claim 3
Dependent Claim
21 words
A method as set forth in claim 1, characterized in that said winding drum and said winding disk are formed integrally.
Claim 4
Dependent Claim
17 words
A method as set forth in claim 1, characterized in that said winding drum is supported fixedly.
Claim 5
Dependent Claim
22 words
A method as set forth in claim 1, characterized in that said winding drum and said winding disk are connected relatively rotatably.
Claim 6
Dependent Claim
156 words
A winding apparatus comprising: 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 said core bar, for securely binding the outer periphery of said core bar by other linear material with a predetermined period.
Claim 7
Dependent Claim
156 words
A winding apparatus comprising: 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 said core bar, for securely binding the outer periphery of said core bar by other linear material with a predetermined period.
Claim 8
Dependent Claim
21 words
An apparatus as set forth in claim 5, characterized in that said winding drum and said winding disk are formed integrally.
Claim 9
Dependent Claim
17 words
An apparatus as set forth in claim 5, characterized in that said winding drum is supported fixedly.
Claim 10
Dependent Claim
22 words
An apparatus as set forth in claim 5, characterized in that said winding drum and said winding disk are connected relatively rotatably.
Claim 11
Independent Claim
29 words
An apparatus as set forth in any of claims 5 to 8, characterized in that a roller is mounted rotatably on the outer peripheral surface of said winding drum.
