Tape adhering method and tape adhering device

Abstract

A tape adhering device ( 10 ) comprises: a drawing roller ( 42 ) for drawing out a tape ( 3 ); a tape fixing means ( 47 ) for fixing one portion of the tape drawn out from the drawing roller; a tape drawing means ( 62 ) for drawing out a predetermined amount of tape, which is fixed by the tape fixing means, from the drawing roller between the tape fixing means and the drawing roller; and a tape adhering means ( 49, 31, 37 ) for adhering the tape, which is located in the downstream of the tape fixing means, onto an object to be adhered ( 20, 36 ) under the condition that fixing operation of the tape by the tape fixing means is released. It is preferable that the length of the tape drawn out by the tape drawing means is not less than the diameter of the object to be adhered. Due to the foregoing, it is possible to prevent wrinkles from being form on the tape at the time of adhering the tape.

1 . A tape adhering device comprising:
 a tape roller for drawing out a tape;   a braking means of a traveling tape for braking one portion of the tape drawn out from the tape roller;   a tape drawing means for drawing out a predetermined amount of tape, which has been braked by the braking means, from the tape roller between the braking means and the tape roller; and   a tape adhering means for adhering the tape, which is located in the downstream of the braking means, onto an object to be adhered under the condition that braking of the tape by the braking means is loosened or released.   
   
   
       2 . A tape adhering device according to  claim 1 , wherein the tape adhering means includes an adhering roller for pressing and adhering the tape to an edge portion of the object to be adhered and also includes a support table capable of moving in the horizontal direction, for supporting the object to be adhered. 
   
   
       3 . A tape adhering device according to  claim 2 , wherein the support table is raised when the tape is adhered to the object to be adhered. 
   
   
       4 . A tape adhering device according to  claim 1 , wherein the tape drawing means is a dancer roller. 
   
   
       5 . A tape adhering device according to  claim 1 , wherein a length of the tape drawn out by the tape drawing means between the braking means and the tape adhering means is not less than a diameter of the object to be adhered. 
   
   
       6 . A tape adhering device according to  claim 1 , further comprising a drive roller for rotating the tape roller in order to draw out the tape, wherein the drive roller stops the tape roller at the time of adhering the tape. 
   
   
       7 . A tape adhering device according to  claim 2 , wherein
 the tape has a shape substantially corresponding to a front surface of the object to be adhered and a plurality of the tape is adhered at predetermined intervals in the longitudinal direction of a base tape,   the tape adhering device further comprising a detection means for detecting a trailing end of the tape, wherein   the detection means is positioned in such a manner that the tape can be arranged being adjacent to the adhering roller when the trailing end of the tape is detected by the detection means.   
   
   
       8 . A tape adhering method comprising the steps of:
 drawing out a tape from a tape roller;   braking one portion of the tape, which has been drawn out from the tape roller, by a braking means of the traveling tape;   further drawing out the tape, which has been braked by the braking means, from the tape roller by a predetermined amount between the braking means and the tape roller;   loosening or releasing a braking action conducted on the tape by the braking means; and   adhering the tape, which is located downstream of the braking means, to an object to be adhered.   
   
   
       9 . A tape adhering method according to  claim 8 , wherein the object to be adhered is supported by a support table,
 when the tape is adhered to the object to be adhered, the tape is adhered to an edge portion of the object to be adhered by pressing the tape and then the support table is moved in the horizontal direction.   
   
   
       10 . A tape adhering method according to  claim 9 , wherein the support table is raised when the tape is adhered to the edge portion of the object to be adhered.
