STRIP WINDING MEANS Filed Sept. 19, 1961 12y; Z8 5' 24 24 fl 3148f E94 INVENTOR.
M/TCHEZL PA R United. States Patent 3,084,884 STRIP WINDING MEANS Mitchell E. Panzer, 55 Oak Terrace, Merion, Pa. Filed Sept. 19, 1961, Ser. No. 139,093 1 Claim. (Cl. 242-74) This invention relates to a strip winding means, and more particularly to a means for removably securing strips of material such as film to a reel or the like.
Heretofore, it has been conventional to secure strips such as film to a reel by inserting an end of the strip into a slot in the hub portion of the reel. Such securement means has not been satisfactory. Quite often, the end of the strip is removed from the slot as the strip is wound around the reel. As a result thereof, the reel will 'be rotated without the strip being wound therearound or the strip will be improperly wound on the reel. Such events are every day occurrences with amateur photographers and the like.
Accordingly, there is a need for a strip winding means which enables strips of material-s such as film to be removably secured to a reel in a facile manner. The securement means should be of such a nature so as to readily permit separation of the strip of film when the reel is unwound. In addition, the securement means should be of such a nature so as to permit it to be utilized with new reels as well as those reels currently in use.
It is an object of the present invention to provide a novel strip winding means.
It is another object of the present invention to provide a novel strip winding means which may be utilized on new reels as well as those reels currently being used.
It is still another object of the present invention to provide a strip winding means to facilitate the winding of strip material such as film on a reel in a facile manner.
It is yet another object of the present invention to provide a strip winding means wherein a strip of material such as filrn may be frictionally retained on a reel and readily separated therefrom when desired.
Other objects will appear hereinafter.
For the purpose of illustrating the invention there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.
FIGURE 1 is a top plan view of a reel incorporating the strip winding means of the present invention which is partially unwound.
FIGURE 2 is an elevation view of the reel and strip winding means illustrated in FIGURE 1.
FIGURE 3 is a front view of the reel showing the strip winding means and film in perspective.
FIGURE 4 is a sectional view taken along lines 4-4 in FIGURE 3.
FIGURE 5 is a transverse sectional view taken along lines 5-5 in FIGURE 4.
FIGURE 6 is an enlarged top plan view of the strip winding means illustrating a manner in which it may be used.
Referring to the drawings in detail, wherein like numerals indicate like elements, there is shown in FIG- URE 1 apparatus designated generally as 10.
The apparatus 10 comprises a reel 12 having spaced parallel side disks 14 and )14'. As shown more clearly in FIGURE 2, the disks 14 and 14' may be of the type having a plurality of arcuately spaced slots therein. The side disks 14 and 14 are interconnected by a hub 16. The reel 12 may be made from metal, plastic, or the like. A strip of material such as film 18 having an end 18' is adapted to be wound around the hub 16 of the reel 12. In order to facilitate the securement of the strip 18 to the reel 12, a strip securing means 20 is provided.
"ice
The strip securing means 20 comprises a sleeve 22 made from a flexible material such as paper, fabric, etc. The sleeve 22 is provided with a plurality of spaced holes 24 extending therethrough at spaced points therealong. A limit stop 26 is provided to limit the extent to which the strip of film 18 may enter the sleeve 22. The limit stop 26 may be readily formed by folding over an integral tab and adhesively securing the same within the sleeve 22.
The sleeve 22 is provided with an integral extension tab 28. The extension tab has a length sutficient to extend around the hub 16 at least once. One surface of the tab 28 is provided with a coating of pressure sensitive adhesive 30. The tab 28 is intended to remain on the reel 12 when the film 18 is separated from the sleeve 22. Thus, other equivalent devices may be utilized to secure the tab 28 to the hub '16. When purchased as a discrete item, the strip securing means 20 will be provided with a removable protective strip on the coating of pressure sensitive adhesive 30.
The apparatus 10 of the present invention is utilized as follows:
The strip securing means 20 may be purchased as a discrete item. The protective strip (not shown) for the coating of pressure sensitive adhesive 38 will be removed therefrom. Thereafter, the extension tab 28 is secured to the reel 12 by wrapping the tab around the hub 16 and applying pressure thereto. The sleeve 22 is of sufii cient length so as to extend beyond the outer periphery of the reel 12 when the entire length of the coating of pressure sensitive adhesive 30 has been secured in position.
Thereafter, the end 18 of the strip of film 18 may be inserted into the sleeve 22. The holes 24 facilitate observation as to the extent to which the film 18 has been inserted into the sleeve 22. The relative dimensions of the strip of film !18 and the sleeve 22 are such so that the strip of film 18 is frictionally retained within the sleeve 22. The amount of frictional retention of the strip of film 18 with respect to the sleeve 22 may be varied by varying the extent to which the strip of film 18 enters the sleeve 22. Thereafter, the reel 12 may be readily wound in any conventional manner. When the reel 12 is unwound, the tension applied to the strip of filrn 18 during the unwinding process easily overcomes the frictional engagement between the strip of film 18 and the sleeve 22.
Thus, the strip of film 18 becomes separated from the strip securing means 20. However, the strip securing means 20 will remain wrapped around the hub 16 and secured thereto by the coating of pressure sensitive adhesive 30.
As illustrated more clearly in FIGURE 5, sleeve 22 is made from a flat layer of material folded over on itself with the edges secured to each other in overlapping relation. However, it will be appreciated that the sleeve 22 may be seamless in nature if desired. As illustrated, the extension tab 28 is integral with the sleeve 22. To facilitate the manufacture, it may be desirable to make the extension tab 28 separate from the sleeve 22. Such an alternative is Within the scope of the present invention. While the present invention has been described in connection with a strip of film 18, it will be appreciated that other strip material may be removably secured to a reel by the strip securing means 20.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claim, rather than to the foregoing specification as indicating the scope of the invention.
