ADHESIVE TAPE Joshua H. Goldman, New Brunswick, N. 1., assignor to The Columbia Mills, Inc., New York, N. Y., a corporation of New York Application April 5, 1941, Serial No. 387,058

' 1 Claim. (CI. 28-80) This invention relates to adhesive tape, and has for its object to provide spaced incisions or perforations adjacent the longitudinal edges of the tape, thereby forming weakened points so the tape can be easily torn transversely.

Another objectis to provide incisions or perforations adjacent the longitudinal edges of the tape and in a manner whereby one or more inwardly spaced threads are provided with interruptions for facilitating transverse tearing'of the tape and at the same time allowing the outer continuous threads to conform to contents being bandaged or wrapped and without the disadvantages of ears which would be formed should the sides of the tape be slit.

A further object is to provide an adhesive tape having transverse and longitudinal threads and interruptions in the longitudinal thread adjacent the longitudinal edges of the tape, thereby weakening the edges so the tape can be easily torn transversely. I

A still further object is to provide a tape having a base of high tear resistance which can be easily and readily torn transversely to provide a bandage or strip of desired length leaving the torn edges straight, smooth, and clean.

With the above and other objects in view, the I invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Fig. 1 is a perspective view of a roll of tape showing the perforations adjacent the longitudinal edges thereof.

Fig. 2 is a plan view of the woven base of the adhesive tape, the weave being shown open for purposes of more clearly illustrating the invention.

Fig. 3 is a detail perspective view, partly in section, on an enlarged scale and showing the severed thread.

Fig. 4; is an end view of a toothed roller which may be used for providing the spaced perforations.

Fig. 5 is an enlarged top plan view of a portion of the tape, showing one of the perforations.

Referring now more particularly to the drawing, the numeral I designates the woven base material which comprises transverse threads 2 and longitudinal threads 3 respectively, one side of the woven base i being provided with an adhesive coating 4, of any material.

In practice it has been found practically impossible at times to tear transversely adhesive tape, such as'used for surgical dressings, du to the bunching of the longitudinal edge strands; consequently, this bunching or ganging resists tear. To overcome this difllculty slits or perforations 5 are placed adjacent the longitudinal edges of the tape as shown in-Fig. 1 of the drawing,

and it will be noted that these slits or perforations are spaced inwardly from the-edges, preferably not more than three warp threads removed, thereby leaving continuous strands 6 at the edges of the tape and interruptions l in one or more strands adjacent the strands B. It will be noted that continuous strands 6 will prevent the formation of cars at the edges of the tape and will cause the tape to conform to the contour of the member being dressed or wrapped, which would not be the case if notches were placed in the edges. At the same time, when it is desired to tear the strip transversely, the tearing operation will easily break the outer strands, as they will not bunch with the interrupted strands at the interruption 1, consequently the tape will easily tear. transversely, and it will be obvious that the tape may be applied directly from the roll and then severed by a shearing pull without the necessity of touching'the tape with the fingers. Two strands are shown with interruptions 1, however it is to be understood any number may be used. Where a paper or other base is used, not

woven, the perforations may-be placed adjacent the edges of the strip.

The tape may be perforated in any suitable manner, and for purposes of illustration, a toothed roll 8 is shown in Fig. 4, the teeth. 9 of which pierce the tape as the roll is rotated. The perforating operation may take place before or after the adhesive 4 is placed on the base, however, the perforations should be visible to the user so they can be easily located for the transverse tearing operation. I

While in the present instance I have shown and described the invention as applied to a surgical adhesive tape, it will be readily understood that the broad idea is also applicable to electricians tape and other formswhich require that strips be severed from time to time.

From the above it will be seen that a surgical tape is provided which may be easily and quickly severed at predetermined points by a tearing operation; that the predetermined points are visible to the operator at all times and the continuous strands at the longitudinal edges are easily parted permitting a smooth clean tear, which would not be the case if the interruptions I were in the outer strands.

The invention having been set forth what is claimed as new and useful is:

As an article of manufacture, a long length of adhesive tape having a woven base, said base comprising longitudinally extending strands; transverse strands interwoven with said longitudinal strands, transversely alined thread interruptions spaced inwardly from opposite sides 01' the tape at substantially equally spaced intervals throughout the length or the tape, said interruptions being adjacent the opposite sides of the tape and forming transverse slits in the longitudinal strands and weakened at spaced places transversely of the tape at spaced longitudinal positions for facilitating the transverse tearing of the tape.
