Abstract
A magnetic tape is wound up in a roll on a pate reel without irregular windings in the roll. A rotary shaft with the tape reel coupled thereto is shifted in one direction of tape width is shifted by a predetermined distance until the magnetic tape at its edge is contiguous or subcontiguous to a reel flange to additionally form a predetermined number of turns of the magnetic tape on a magnetic tape roll so as thereby to form an annular peripheral lip portion laterally extending at one side of the magnetic tape roll when the magnetic tape roll grows as large in size as predetermined.
Claims12
A magnetic tape winding apparatus for winding a magnetic tape onto a tape reel having flanges, said magnetic tape winding apparatus comprising:
- a rotary shaft movable in opposite axial directions thereof to which said tape reel is detachably coupled;
- driving means for driving said rotary shaft in a home position to wind said magnetic tape onto said tape reel;
- roll length detection means for detecting a roll length of magnetic tape roll growing on said tape reel;
- and
- shifting means for shifting an axial position of said rotary shaft in either said axial direction from said home position;
- wherein said shifting means shifts said rotary shaft in at least one of said opposite axial directions from said home position by a predetermined distance to additionally form a predetermined number of turns of said magnetic tape on a predetermined roll length of magnetic tape roll before termination of said winding of said magnetic tape onto said tape reel so as thereby to form an annular peripheral lip portion on at least one of opposite sides of said tape roll when said roll length detection means detects a predetermined roll length of magnetic tape roll, and said driving means is stopped when said predetermined number of turns of said magnetic tape are formed.
A method of winding a magnetic tape onto a tape reel having flanges, said magnetic tape winding method comprising the steps of:
- driving a rotary shaft in home position to wind said magnetic tape onto a tape reel coupled to said rotary shaft;
- shifting an axial position of said rotary shaft in either axial direction of a rotational axis of said rotary shaft from said home position by a predetermined distance to additionally form a predetermined number of turns of said magnetic tape on a predetermined roll length of magnetic tape roll while winding the magnetic tape onto the tape reel so as thereby to form an annular peripheral lip portion on at least one of opposite sides of said predetermined roll length of magnetic tape roll when detecting a predetermined roll length of magnetic tape roll growing on said tape reel;
- and
- stopping said rotary shaft when said predetermined number of turns of said magnetic tape are formed.
A method of winding a magnetic tape onto a tape reel having flanges, comprising the steps of:
- driving a rotary shaft to wind the magnetic tape onto the tape reel coupled to the rotary shaft;
- shifting an axial position of the rotary shaft in a first axial direction of a rotational axis of the rotary shaft so that a first edge of the magnetic tape is directly adjacent a first one of the flanges of the tape reel;
- first winding the magnetic tape onto the tape reel a first plurality of turns, wherein the first edge of the first plurality of turns of the magnetic tape is directly adjacent the first one of the flanges;
- shifting an axial position of the rotary shaft in a second axial direction of the rotational axis of the rotary shaft opposite the first axial direction so that a second edge of the magnetic tape opposite the first edge is directly adjacent a second one of the flanges of the tape reel opposite the first flange;
- second winding the magnetic tape onto the tape reel a second plurality of turns, wherein the second edge of the second plurality of turns of the magnetic tape is directly adjacent the second one of the flanges;
- and
- stopping the rotary shaft after the second winding step.
