3 Claims. (Cl; 206-47) This invention relates to a novel method of splicing tapes, particularly sound tapes, and to a kit embodying the necessary equipment to practice the method.

An object of this invention is to provide a method of splicing sound tape wherein the abutting ends of two tapes" are heldtogether with a minimum of continuity displacement therebetween.

Another object of'this invention is to provide a small portable kit embodying a combination of all the necessary equipment to'effect the splicing, the parts comprising simple but effective means for the proper splicingv of sound tape by those with little or no experience in this field.

And another object of this invention is to provide a. set ofcooperatiVe parts which may be set up at any con venient location, and the method practicedrtherewithwith a minimum of elfort and time.

Other objects. and advantages :of. this invention relating to the arrangement, operation and functions of the related elements of the structure, to various details of construction, to combination of parts and to economies of manufacture; will'beapparent to those skilled in the art upon consideration-of the following description and appended claims, reference being-had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

Referring to the drawings:

Fig. 1 is a side view of the kit disclosed herein;

2 provide the attaching element 18. The strip '18 has. a substantial thickness so that in holding the block mounted on the plate '10,, a pocket 20 is provided between the blockand the plate. This provides a convenient storage space fora cutting tool '22, herein shown as a single-edge safety razor blade. By inserting the cutting. edge of the Fig. 2 is a view of the opposite side of the kit of Fig. 1;

:Fig. 3 is an enlarged end view of the kit, the major parts thereof shown separated for purposes of illustration;

Fig. 4 is a plan view of the splicing block illustrating a step in the method disclosed herein;

Fig. 5 is a view on the line V-V, in Fig. 4; and

Fig. 6 is a view similar to Fig. 4 illustrating an additional step in the method.

The kit herein disclosed includes the combination of a pair of major items enclosed within an envelope, which is sold as a unit, and contains all the necessary equipment and material for the splicing of a number of sound tapes.

The kit includes a card-like sheet or paperboard plate 10 having one side 12 thereof coated to provide a glossy or enamelfinish thereon. The opposite side 14 may be untreated and provides space for carrying printed instructions for the use of the equipment mounted on the side 12. This equipment includes splicer block 16 which has a pressure sensitive strip 18 adhering to the rearward or back face thereof. This material 18 is a length of double-faced pressure sensitive tape so that one side thereof may adhere to the block 16 while its opposite face may have a limited adhesive attachment to the face 12 of the card or plate 10.

The glossy surface of the paperboard plate 10 resists Strong adhesion thereto by the tape of the type used to blade 22 into the pocket 20 between the plate. '10. and the strip 18 or between the strip 18. and the block 16, both the cutting-tool and the block are mounted onthe plate 10 with sufhcient adhesion to permit normal handling and maintain regular storage in the kit. as sembly.

The kit also includes a second paperboardplate or card-like sheet 24, likewise havinga glossy or enamel surface 26 on. one side thereof, and an untreated. surface 28 on its opposite side. The faces 14-and 28 are placed together in the kit, and being of ordinary paper stock have little or no tendency to stick together. The face 2'8 may also include additional instructions particularly' directed to the use of the materials mounted. on the opposite or glossyside 26. The plate 24 i's'preferably of rectangular form and has placed along. the surface 26 thereof a plurality of. tapes 30' sospaced as. to. provide exposed portions of the face 26. on each. side of each of ,the tapes 30, which tapes are herein shown asv three in number.

Thetapes 30' are of a material best sdescribedlasrayon fabric or acetate rayon. The tapes. 30 areQpreferably disposed longitudinally, alongthe surface of. the plate. 241 Transversi'ng the tapes 30'isa series ofpressure.sen'si tive lesser tapes, or ribbons, 34', which may be ofthe: type known as 3M-41. Several spaced stripsof this ribbon may extendlaterally across the card-ZIengagiDg. the outer surfaces of the tapes- 30 and the exposed portibns 32 ofthe. supporting surface. i

This particular combination. of the tape. and ribbon provides'a-unique result. The ribbons 34 beingpressure sensitive, have a limited'afiinity for the card surface and practically no adhesive aflinity for the tapes '30, and the adhesion to the glossy card surface is so limited that the ribbons 34 are easily peeled from the glossy surface of the card, and even more easily separated from the tapes 3!). The ribbons 34 have severed joints 36 in the reg'ions of the intermediate exposed areas 32. This cuts each lateral ribbon 34 into a series of patches 38, herein shown three to each ribbon. The result is that a comparatively large number of patches may be placed on a comparatively small card. The cards 10, 24 are placed back to back, and then inserted into an envelope 40, which may -be formed from a transparent plastic sheet and which serves as a carrier and protector for the kit parts and allows display therethrough.

The envelope 46 may be easily opened and the two I contained cards separated. The .splicer block is easily removed from the card and will carry the strip 18 therewith. This adhesive back on the splicer provides a convenient mounting for the block on any convenient working surface, simply by pressing the block firmly into place. Such block may even be easily mounted on a recorder without damage to the surface finish thereof.

The tape ends to be spliced are pressed into the groove 42 extending longitudinally and centrally across the block 16. This groove 42 is of a slightly less width than the width of the tapes to be spliced. Thus, by pressing the tape ends into the groove, edge friction will hold the tape therein in place without the use of any additional clamping means (Fig. 5). The ends of the tape are pressed into the splicer groove overlapping each other, as for example about one half inch with the oxide recording surface face down. The two tapes are thus held firmly together.

When the tapes are positioned within the block, the cutting edge of the blade 22 is drawn through one of the guide slots 44 extending across the face of the block 16. These guides 44 determine the angular extent of the out made through the tapes whereby an end to end abutting cut may be made or a diagonal cut, if so desired. Sufficient pressure is exerted against the cutting tool so that the cut 46 is made through both thicknesses of the tape. Following this cut, the tail end 48 of the tape may be removed from the jig. This leaves the entire upper faces of the tapes 50, 52 exposed without any overlap therebetween. The cutting tool may be conveniently. used to remove this tail piece by working one corner of the blade under the tail piece and lifting it free as the severed piece will tend to adhere to the blade. A patch 38 is then removed from the card 24 and pressed onto the tapes 50, 52 bridging the cut 46. This pressure sensitive piece has a strong adhesive attraction to the exposed surfaces of the tapes and will lock the abutting ends thereof and securely hold the same. When the patch 38 has been firmly pressed across the cut 46 and smoothed into continuous adherence throughout its length, the two tapes t 52 may be grasped and lifted free from the block 16 with the splice complete.

A splice thus produced With normal care holds the abutting ends so closely together that the juncture is hardly noticeable on the oxide side and the patch 33 is of such thinness that there is a negligible disturbance in the continuity of the joined sound tape.

' In the fabrication of the cutting blocks, a slab of plastic is out to the desired dimensions and the groove 42 is formed thereon by a suitable tool. In the cutting of this groove 42, the sides 54 thereof, which are substan t-i-ally perpendicular, are provided with a roughened or non-polished surface. This roughened surface further adds in gripping the tape therehetween for frictional holding without. an actual bind.

It is to be understood that the above description of the present invention is intended to disclose an embodiment thereof to those skilled in the art, 'but that the invention is not to be construed as limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of being practiced and carried out in various ways Without departing from the spirit of the invention. The language used in the specification relating to the operation and function of the elements of the invention is employed for purposes of description and not of limitation, and it is not intended to limit the scope of the following claims beyond the requirements of the prior art.
