Abstract
Title of the Invention Automatic Transferring Device for Double-Coated Adhesive Tape Abstract of the Disclosure The present invention relates to an improvement in the structure of an automatic transferring device for the double-coated pressure sensitive adhesive tape, capable to transfer the adhesive substance of the tape roll to the desired position in simple and positive manner. The tape roll comprises a double-coated adhesive transferring tape coated with the pressure sensitive adhesive substance on one face of the double-sided released paper.
Description
~ 399~ 3 Back~round o~ the Invention This type of the double-coated adhesive tape has been increasingly and widely used in recent years, because it is capable, unlike the con~entional double-coated adhesive tape, to have the adhesive effect only by the adhesive substance with no core material and because ideal adhesive results can be obtained by the property of adhesive substance only.
In a known transferring device, a tape roll support shaft is mounted in a casing, on which a tape roll is rotatably supported. The tape roll takes up a double-coated adhesive transferring tape, wherein pressure sensitive adhesive substance is coated on one face of the double-sided released paper. The tape is rolled on the tape roll support shaft in such manner that the surface coated with the adhesive substance faces outward. Further, a pressure plate similar to a plate spring is mounted inside the casing in the direction opposite to the rotating direction of said tape roll, applying the braking -force in such degree as to block free rotation of said tape roll. An outlet is provided for the double-coated released paper from which the adhesive substance has been released and transferred.
The au~omatic transferring device for the double-coated adhesive transferring tape with the construc-tion as explained above causes no particular problem so far as the user applies an even force on tape surface and presses it positively on the article to be transferred unless the double-sided released paper is slackened and ycc/sp 1 ~
~ 3')q~''3 caught in the space under the outlet of said released paper. However, if tape is run with its surface inclined, the adhesive substance is forced to remain on the double-sided released paper, blocking the smooth contact rotation thereof with the pressure plate or obstructing the discharge of the released paper from the outlet. For this reason, it is necessary to acquire a sort of skill until the user becomes able to use it without trouble. Because the pressure plate is disposed to the direction opposite to the rotating direction of the double-sided released paper, the tape roll ycc/sp 2 1 3'`9693 receives relatively big resistance during rotation. This is often likely to cause the slackening of the tape even when the adhesive substance re~aining on the double-sided released paper does not s-tick. The slackening further causes the tapa to sag and hinders the rotation of the tape a-t the position, where it contacts with the pressure plate, which faces opposite to the rotating direction of the tape roll, making it impossible to transfer the ad-hesive substance in the smooth and constant conditions.
In addition, it is extremely difficult to have the casing straightly faced toward the surface to be transferredu When it is run in inclined position, the adhesive sub-stance is not uniformly transferred to -the desired surface, and the adhesive effects are not obtained as desired.
There have been the following proble~s in the double-coated adhesive transferring tape itself, used in the automatic transferring device for this type of adhesive tape:
In recent years, the double-coa-ted adhesive transfer-ring tape is extensively used, wherein a shee-t of double-sided released paper is coated with adhesive film and is rolled up in the shape of a tape roll. Compared with -the conventional type of double-coated adhesive transferring tape, using a core material, this new type of double-coated adhesive transferring tape is a simple but ideal type o-f tape, ~hile the following problems still remain unsolved:
1 :~ ') 9 ~'. ',' 3 Because adhesive substance film is coated all over the upper surface of the double-sided released paper9 the adhesive substance tends to protrude to bo-th sides when the paper is rolled up into the shape of tape. For instance, when this tape roll is used within the casing of the au-toma-tic transferring device, the protruding adhesive substance sticks to -the inner surface of the casing and hinders the smooth and perfect rotation and feeding of the double-coated adhesive transferring tapeO
At the same time, the adhesive substance stuck on inner surface of the casing is often separated, resulting in the pressure sensitive transfer of the double-coated adhesive transferring tape, which now partically lacks the adhesive substance. In the course of transition and adhesion to the desired position of this type of double-coated adhesive transferring tape, the adhesive tape is cut off by stron~ly pressing the automatic transferring device and by raising it to the desired position. This requires, however, a considerable degree of skill and force, and fa-tal defects are often caused such as the defect, wherein the tape is not properly cut o~f at the desired position, resulting in the rais-ing of the tape together with the automatic transferring device and in the separa-tion of the stuck portion of the tape, or the defect, wherein the desired end portion is not disposed in ~ood order. In order to eliminate such defects, it was proposed to arrange -the pieces (pa-tches) 1 3',~kq3 of adhesive substance consisting of adhesive film on the double-coated released paper - lengthwise in the conkin-UOU5 manner each wi-th a certain intermediate space - where the double-coated released paper was sometimes exposed in the longitudinal direction. According to -the present improvement, the adhesive taPe is incorPorated in the automatic transferring device as a tape roll and is used as a direct pressure sensitive roller. Because adhesive substance is not coa-ted in the intermediate space be-tween the patches of the adhesive substance, the disad-vantageous condition of the -tape is now eliminated, where the tape could not be cut off even when it is strongly pressed and then pulled up. The desired ~idth o~ the double-coated adhesive transferring tape can now be transferred and adhered in simple manner. At the same time, -the adhesive substance can be transferred and adhered to the desired end portion, and there is no possibility that the adhesive substance is turned to liquid state or it becomes uneven in thickness as often experienced in the prior method of pressing and cutting.
Even in this type, however, -there remains -the pos-sibility that the adhesive substance may protrude from the sides when the tape roll is placed in the automatic transferring device and that it sticks to the inner sur-face of the automatic transferring device, hindering the perfect rotation and feeding of the -tape because the adhesive substance is coated on upper side and lower ~;' 1 309~q3 side of the patches of adhesive substance in longitudinal direction~
Summary of the InYention The present invention brings an improvement to the double-coated adhesive transferring tape itself. At the same time, it ~ims to offer an automatic transferring device for the double-coated adhesive transferrin~ tape, enabling even the unskillful and inexperienced users to perform -the proper transferring operation and suitable to store in adequate manner when it is not in use. ~or this purpose, various ideas and means have been added for the automatic transferring device for the double-coated adhesive transferring tape~ where the double-sided re-leased paper coated ~ith the transferred adhesive sub-stance is smoothly guided toward the outlet and discharged in order to prevent the slackening of the double-sided released paper within the casing. Even when the adhesive substance may remain on the double-sided released paper, the double-sided released paper is discharged witbout any trouble. Because the tape roll is rotated properly and the transferring operation is performed in the ade-quate direction, there is no possibility that the adhesive substance is not transferred in good order to the desired position even whsn the tape is run in inclined position.
Thus, the feeding of the released paper as well as the transfer of the adhesive substance to the desired surface are conducted positively and properly.
1 3 ,q~!193 Accordingly, there is provided a device for automatically transferring a double-coated adhesive transfer tape of the type having adhesive substance to be transferred coated on a release material in a discontinuous manner such that portions of the adhesive substance are separated by small intermediate spaces in the longitudinal direction, and longitudinal edge portions of the release material are not coated with the adhesive substance, leaving portions of the release material exposed on upper and lower sides of the release material. The device comprises a substantially hollow casing and means for rotatably supporting a roll of double-coated adhesive transfer tape loca-ted inside the casing. A resilient pressure plate contacts the roll of tape for hindering the free rotation thereof. The pressure plate has a first end attached to the casing and a second end having means for contacting only the longitudinal edge portions of the release material not coated with the adhesive substance. An opening is provided in a lower part of the casing for exposing at least the patches of adhesive substance on the roll of tape rotatably supported on the support means outwardly of the casing for transferring the adhesive substance to a substrate. An outlet in the casing is provided for discharging the release material from which the adhesive substance has been transferred to a substrate. A guide piece is provided on the casing having a groove or slot directed toward the tape roll and a free contact piece is slidably received in the groove or slot of the guide ycc/ 6a , ~
i 1 3 ~ ~'' 9 3 piece. The free con-tact piece contacts the tape roll for preventing slack in the release material of the transfer tape from which the adhesive substance has been transferred.

Detailed Description of the Embodiments In the following, an embodiment of the present invention is described with reference to the accompanying drawings.
In Figs. 1 through 7, (1) shows a transferring device. In this transferring device, a tape roll support shaft (3) is mounted in a casing (2) provided with a cover (2a). As shown in Fig. 4, the pieces (patches) of pressure .f~ ycc/sp 7a 1 3"''~93 sensitive adhesive substance (5) are coated on one face (4a) of the double-sided released paper~ A tape roll (6) is ro-tatably supported on the support sha~t by rolling up the double-coated adhesive transferring tape in such manner that the dry edge portion (4b) is formed with no adhesive substance on upper and lower sides of the double-sided released paper (4) in the longitudinal direction.
As shown in Fig. 5, a pressure plate (7) similar to a plate spring, having a notch (7b) to avoid the contact of the contact piece (7a) with the adhesive substance (5), is prov.ided inside said casing ~2)o The pressure plate is in contact only with the dry edge por-tion (4b) of said double-sided released paper (4) in order to block the free rotation o~ said tape roll (6). The pressure plate controls the discharging direction of the released paper and, at the same time, applies the braking ~orse in such degree as to prevent the free rotation of said tape roll (6). In the drawingsg (8) shows an exposed portion of the tape, and (9) is an outlet for the double-sided re-leased paper t having a notch (9a) to avoid the contact with the remaining adhesive substance. It is provided on the surface (4a) coated with adhesive substance (5) of said double-sided released paper (4) in the same manner as said pressing plate (7) to discharge the double-sided releasaed paper (4) already coated with the adhesive substance (5). (10~ is a guide piece, having the shape of a groove or a slot, as provided inside the pro-truding I ;'~".q6')3 por-tion (11) located at the po~ition more advanced toward the rotating direction of the -tape roll than said outlet (9) of the casing (2)o This guide piece (10) accommodates a free contact piece (12)~ made of relatively heavy material such as iron to enable free falling towaed said tape roll by its own weight. It is furnished with a notch (12a) to avoid the contact with the adhesive substance in the same manner as said pressin~ plate (7). Accordingly, it not only gets in touch with the patches of the adhesive substance, as produced by the rotation, but also plays the role as a stopper. This eliminates the possibility that the released paper is slackened and caught in the space inside the casing as the tape roll is rotated.
(13) is an index finger placing plate and consists of the lower part of the protruding portion (11) and a plate adjacent to it, inclined uPward to~ard the upper surface of the casing. Said index finger placing plate (13) is provided with protuberances or indentations (13a) -to catch the finger.
(14) and (15) are the protuberances or indentations, provided on both sides o-f the lower portion of the casin~
in the direction of transfer and are used to catch the thumb or middle fin~er. By holding the casing with thumb, index and middle finger at these positions, the transfer operation can be performed perfectly because tape surface is straigh-tly faced toward the surface to be transferred and the tape is run in the inclined 1 ) ,`/~!9 3 position, and there is no possibility tha-t adhesive substance is not transferred to the desired position in good order. When necessary, the guide piece may have th~ structure as shown in Fig. 7. In Fig~ 7, (16) is and a protuberance as formed on the side of the guide piece, ~hich has the shape of a groove or a slot. The protuberance is positioned in the notched groove (17), which is formed at the end of the free-falling -free contact piece, hindering it from dropping off -toward la-teral direction when the cover is removed to replace the tape.
(18) is an opening on the casing for hanging purpose to use when the automatic transferring device for double-coated adhesive tape is stored or left unused.
The automatic transferring device for double-coated adhesive trans-ferring tape based on the above-mentioned structure can offer perfect rotation effect for the tape rolln It is so designed that the tape itself is provided with the dry edge portion ~i-thout adhesive substance on upper and lo~er sides in longitudinal direction of the double-sided released paper, making the width of the coated adhesive substance on the double sided released paper smaller than the width of said double-sided re-leased paper. A guide piece having the shape of a groove or a slot is provided within the protubernce on upper and inner side of the casing at the position more advanced toward the rotating direction of the l ,~, ",q~'j93 tape than the outlet. A free contact piece made of the material ~ith relatively heavy weiKh-t such as iron is furnished inside the guide piece so that it falls do~n freely toward the direction of said tape roll by its own weight. This ~ree contact piece is provided with a notch so that it gets in touch only with -the dry edge por-tion and not with the adhesive substance of the rotating tape roll. Thus, the automatic trans-fer device can perform per-fect rotation effect for the tape roll. At the same time, the double-sided released paper coated with the adhesive substance can also be guided and discharged in proper manner toward and through the outlet by the stopper ac-tion and the guide action of said free contact piece~ which rolls up the released paper into the casing. On the pressure plate similar to a spring9 hindering the free rotation of the tape roll, a notch is provided to press only the dry edge portion and not the adhesive substance. In the same way, a notch is furnished on the surface of the outlst.
The notch makes it possible to dischar~e the double-sided released paper without trouble even when adhesive subs-tance remains on the double-sided released paper.
In case the pressure plate similar to a spring, hinder-ing the free rota-tion of said tape roll, is mounted to the same direction as the rotating direction of said tape roll, almost no resistanca occurs against the forced rotation of the tape roll. Thus, tape is not q ~ 9 3 slackened and tape roll is rotated very smoothly, result-ing in perfect transfer operation of the adhesive substance in stabili~ed and assured manner.
Another advantageous feature o~ the present inven-tion is the positioning of middle finger, thumb and index finger, facilitating to hold the casing straightly toward the surface to be transferred. This makes it possible to prevent the tape from running in the in-clined position and to transfer the adhesive substance to the desired position in good order.
This eliminates the possibility that -the tape may be run in the inclined position, that the adhesive substance may not be transferred to the desired position in good order and that the adhesive effect may not be conducted as desired.
More convenience is provided in the replacement of tape roll, because the dropping-of-f of the free contact piece toward lateral direction is preven-ted. An opening is furnished to hang the casing when not in use, and the device can be hung or suspended on the hook or by other means mounted on the side of the desk or on wall when it is not used.
In a known transferring device, a tape roll support shaft is mounted in a casing, on which a tape roll is rotatably supported. The tape roll takes up a double-coated adhesive transferring tape, wherein pressure sensitive adhesive substance is coated on one face of the double-sided released paper. The tape is rolled on the tape roll support shaft in such manner that the surface coated with the adhesive substance faces outward. Further, a pressure plate similar to a plate spring is mounted inside the casing in the direction opposite to the rotating direction of said tape roll, applying the braking -force in such degree as to block free rotation of said tape roll. An outlet is provided for the double-coated released paper from which the adhesive substance has been released and transferred.

The slackening further causes the tapa to sag and hinders the rotation of the tape a-t the position, where it contacts with the pressure plate, which faces opposite to the rotating direction of the tape roll, making it impossible to transfer the ad-hesive substance in the smooth and constant conditions.

This makes it possible to prevent the tape from running in the in-clined position and to transfer the adhesive substance to the desired position in good order.
This eliminates the possibility that -the tape may be run in the inclined position, that the adhesive substance may not be transferred to the desired position in good order and that the adhesive effect may not be conducted as desired.
More convenience is provided in the replacement of tape roll, because the dropping-of-f of the free contact piece toward lateral direction is preven-ted. An opening is furnished to hang the casing when not in use, and the device can be hung or suspended on the hook or by other means mounted on the side of the desk or on wall when it is not used.
