TAPE SUPPLIER Description of the Invention This invention relates to tape dispensers of the kind in which a coating composition when being laid on a substrate surface is supplied carried on a tape and the use of the spout the coating composition is transfers onto the surface of the substrate as a continuous strip, while the carrier tape is retained by the spout Such tape spouts are known and are used for example to apply a correction composition to cover a typing or typing error and to allow A Correction Is Made In these known correction tape dispensers, separate tape supply reels and winding reels are generally provided inside the dispenser box and the two reels are linked by a drive mechanism in such a way that As the tape is removed for use of the supply reel, the reel of The winding is rotated to wind the used carrier tape. Also, since the rotational speeds of the reels are not the same, some form of clutch mechanism is usually needed. The need for a clutch increases manufacturing costs which is a disadvantage, especially since many jets are designed to be discarded after the initial supply of tape has been used Because, when it is manufactured and used for the first time, essentially all the tape is carried by the supply spool, while in the final use the supply spool is empty and all the The carrier tape is wound on the winding reel, the respective spools require considerable space inside the spout body, which also serves as a REF: 27064 handle to retain the spout during use Consequently, the length of tape that can be supplied in a dispenser is limited if the body does not become too large and as a result makes the assortment Annoying and inconvenient to use This disadvantage is especially acute where it is desired to provide a spout with a thin elongate body or handle, to allow it to be retained in a manner similar to the manner in which a pen or marker is held in the hand To alleviate the above disadvantages, the present invention provides a tape dispenser comprising a body that accommodates a supply of tape consisting of a carrier tape that carries a coating of a composition to be transferred onto a substrate surface and arranged to store the used carrier tape from which the composition has been separated, wherein the supply of tape is retained in the form of an elongated spool wound around a pair of spool elements spaced apart and rotatable independently More advantageously, the ends of the carrier tape are joined jointly and the used carrier tape is stored on a common reel with the rest of the tape not used By retaining the supply of tape on an elongated reel, for example an oval reel where the reel elements have the same diameter, substantially more tape can be accommodated in an elongated spout housing than is possible with the storage arrangements of conventional tape In addition, by storing the used carrier tape in a common reel with the unused tape, it is not necessary to provide additional separate space within the housing to accommodate the used tape, as is the case with the prior art jets With a continuous oval reel from which the tape is withdrawn from the inner winding for supply to an applicator head and the used carrier tape is returned to the external winding, the slippage occurs naturally between the wound layers of the spool The frictional effects of this slippage can depend on the control of the tension in the tape in the section extending to and from the head of the designer, whereby the need for drive and clutch mechanisms between the reels can be eliminated. An alternative method to control the tension of the tape is to mount the reels in such a way that they can move towards each other and provide spring means to separate the reels In order to facilitate a clear understanding of the invention, a specific embodiment is described in more detail below, reference is made to the accompanying drawings, in which Figure 1 is a schematic illustration showing the oval winding of the ribbon, and Figure 2 is an exploded perspective view of a correction tape dispenser according to the invention. Referring initially to Figure 1, a reel of correction tape retained within a correction tape dispenser is shown. is of a known type consisting of a length of carrier tape, for example of plastic or paper, on which it is transported the correction composition which will be disposed on a surface by the spout In accordance with this invention, the ends of the carrier tape are spliced together in such a way that the tape is a continuous circuit and the tape is wound in vain layers superimposed around each other. a pair of spool elements of equal diameter spaced apart, 2, 3 to thereby form an oval spool of tape As can be seen in figure 2 the oval spool is accommodated in an elongated box 4 of generally thin configuration and as described In more detail below, a section of tape between the inner and outer windings of the reels is arranged to extend out of the box and onto an applicator head which is used to press the tape against the substrate surface in use of the tape. As illustrated in Figure 2, the box 4 is assembled from two parts which support between them a pair of spindles spaced 6, 7 on the The two reel elements 2, 3 are respectively carried for their independent rotation about respective axes. The head 5 of the applicator projects from the front end of the box and at its free end carries a point 8 with an edge 9 around it. from which the tape passes. The tape is guided to and from the tip by pairs of guide pins or rollers. The box can be rotatably adjustable in relation to the head of the applicator, as described in the co-pending patent application No when the tape is pressed against a substrate surface by means of the edge 9 of the tip and the tip is brought back on the surface in a direction substantially perpendicular to the edge, the correction coating is transferred to the surface from the carrier tape and disposed as a continuous strip. new tape is removed from the supply reel In the illustrated arrangement, the new tape is drawn from the innermost winding of the reel on the rear reel 3 To assist in this separation from the reel tape, this reel 3 preferably has a profile of such way that it acts to move the innermost winding of the spool plane The separated tape passes over the front spool 2 and to the guide pins / rollers 10 before traveling to tip 8 of the applicator The carrier tape that has passed around the edge 9 of the tip and whose correction composition has been separated therefrom, is similarly guided by a pair of guide pins / rollers 10 before being supplied to the tape reel in the outermost winding near the front spool 2. As the supply of correction tape is used, the oval reel of the tape is gradually replaced by the used tape, in such a way that no additional space is needed inside the box to accommodate the tape. As the tape is supplied from the inner winding of the oval reel, the outer layers move inward and some slippage between adjacent layers. The friction between the slip layers can be used to ensure that the necessary tension is obtained in the belt to control the portion extending to and around the head of the applicator. It will be readily recognized that the amount of tape held in the oval reel of Figure 1 is substantially greater than that which would be stored in the same number of layers around a single cylindrical spool. It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention is the conventional one for the manufacture of the objects to which it refers. Having described the invention as above, property is claimed as contained in the following
