FEED ROLL Andre Tempe, West Orange, N. J. Application June 3, 1946, Serial N 0. 674,148

2 Claims. (01. 271 -2.3)

The present invention relates to improvements in adhesive or sticky tape dispensers and more "particularly to a feed roll employed as part of the mechanism thereof.

One of the objects thereof is to provide a sim ple, efficient and inexpensive feed roll, the function of which in the complete dispenser unit is to have wound up upon itself a determinate length of the adhesive or sticky tape coming from an unwinding reel of the machine, which represents that portion of the reel wound tape which it is desired to sever automatically from the rest of the tape. The length of the arc of the periphery ofthe feed roll or drum covered by the adhesive or sticky tape represents the portion of the entire reel of tape which it is desired to cut off.

Another object of this invention is to devise a form'of feed roll for adhesive or sticky tape, for "use upon a machine dispensing same progressively in severed lengths, which has provision for prodding the gummed surface of the tape clinging to its periphery upon rotation of the roll, so that teats will provide the setting for the tape instead of flat surfaces. As a result of this arrangement A and disposition and bearing of the tape which it is desired to sever from oif the roll will more easily be stripped off from the roll and more rapidly than would be the case otherwise.

A'still further object thereof is to provide a form of feed roll for adhesive or sticky tape, which is fed in adhesive contact with the periphcry thereof, which is provided with a continuous- 1y broken periphery transversely thereof and circumferentially thereof at the same time for the purpose of providing a series of rows of separate lugs as those parts of the roll which receive the sticking tape. This has the important office of facilitating the removal, or stripping of the tape from the feed roll because voids'are provided in V the shape of grooves and slots between the various groups of tape holding lugs over which no part of the tape can adhere.

A still further object thereof is to provide a "feed roll, of the kind described, in which is provided a chamber on one side receiving the intermittent feed device aswell as the severing and stripping means with which the complete adhesive or sticky tape dispenser is provided. These parts of the machine have show up in or through the grooves and slots in projecting elements which the course of performing their allotted functions.

Another object thereof is to provide, in a device of the kind described, improved means adapted to present a peripheral surface to the training of a portion of adhesive or sticky tape for winding purpose therearound, which is knurled so as to roughen this face of the feed roll and exhibit a multitude of tiny depressions against the sticky surface of the tape, and which is also interrupted at uniform distances apart circumferentially of the roll to provide metering openings or slots to which the tape will not adhere at all. About onefourth of the total periphery of the feed roll of my invention presents non-adhering intervals thereon.

With the above and other objects in view, my invention consists in the combination, arrangement and details of construction disclosed in the drawings andspecification and then more particularly pointed out in the appended claims.

Figure 9 is a detailed section taken on the line 9--9 of Figure 7 and Figure 10 is a fragmentary section taken on the line ill--19 of Figure 9.

Referring to the drawings,- which are merely illustrative of my invention, the various details of construction are disclosed. V The 1" eed roll may be cast or made from sheet metal, both forms of this roll. being herein shown and described. The cast type is shown in Figures 1 to 5 inclusive. A cylindrical metal body or disk I0 is shown formed with a central bearing opening ll.

' I of lugs extending crosswise of the body. The

annular grooves i9 areseen intersected by the circular series of transverse slots i The arcuate outer faces of all of the lugs are knurled as at Ha. The transverse slots formed in the central flanges are designated lfia. The end walls of each pair of successive lugs which confront each other are designated il, E3. The slots it intervene between these walls.

The base lines of the slots 59 are denoted at .20, and the base lines of the slots iii are desig-' hated it. It will readily be seen that the base lines of slots it are in a higher plane than the base lines of the slots 59, from Figure 1.

Figure 2 shows that the base linefit of slots iii forms'the periphery, in each case, of the grooves extending between the parallel rows of lugs, of a drum. Figure 3 shows clearly how the slots l9 project inwardly of this periphery ll of the feed rollp Hence they slots It are formed between the confronting end walls ll, 13 of the lugs, while the deeper slots iii are formed between their side walls 11b, lii b as shown in Figure 2.

Formed in the feed roll, in one of the sides thereof, is a central cylindrical chamber the back wall of which is designated 22, and the inner circumference ofwhich is designated 23. The outer circumference of this chamber theperiphery 2! of the drum. This chamber, therefore, communicates with all of the radially disposed slots I5 thereadiacent. Th chamber extends only part way inwardly of the widthof the lugs I3 which intervene between these slots IS. The chamber also registers with the bearing opening ll, formed in the feed roll.

Another modified form of my invention is disclosed in Figures 6 to 10 inclusive.

In this form of my invention the feed roll is made from sheet metal. A hollow drum-like body is intended to be produced. The sheetmetal blank is upset and bent irregularly to produce two parts; one part forming the drum proper, and the other part producing the hub section.

The manner in which the sheet metal blank is shaped is such that one flat side wall 24 of the drum is produced. The material is then upset and bent back upon wall .24 to provide a right angular narrow annular band 25- upon side wall 24. The annular band 25 is. upset and bent or stamped to provide the first of a parallel series of adjacent intermediate walls. The first of these walls is designated 26 and extends as a right angular inturned flange formed upon the band 25. The flanged intermediate wall 26 is formed integrally with an annular band 21 at its base, the crest of this flange being formed integrally with the band25.

In stamping out this drum, there will be three bands 21 formed between intermediate flange walls 26, 28, 28a and Y28, and 28a and29a. The

flange walls 28, 28a, Z8, 28a and 29a are formed integrally so as to extend upwardly from the band 21. Flange walls 28, mm are joined by a narrow band 29, in each case. It will be seen that narrow band 29 are in peripheral alignment with band 25, and that the inset bands flare all in peripheral alignment with each other. The-flange operation.

wall 29a is formed with a right angular band 28b to the right thereof, which is as wide as band 25, and in peripheralalignment with the bands 25, 29, and 2812. Finally, band 2% is formed with a depending annular flange 29 disposed parallel with side 24 of the hollow sheet metal drum. It is seen that wall 24 forms one disk-shaped side of the drum, while flange 29 forms the periphery the other sidethereof. 3 There has thus been produced'four cylindrical hollow flanges, of which the two endmost are widest. However, these parts of the drum would be flanges only if no further upsetting thereof took place for the purpose of producing the hollow lugs. For this purpose Figure 8 shows that, circumferentially of the drum, interrupted slots are provided at 32 in parallel rows extending transversely of the feed roll.

The side walls 3|, 26, 28, 28a in both instances, and side walls 29a, 29, form however, side walls of, polygonal lugs which are hollow inside as at 4 l The end walls thereof are designated 38, 39, in Figure 8. The end wall 39 of one lug confronts in spaced relation the end wall 33 of the next adjacent. hollow lug to'provide the intervening slot 32. A circumferentially spaced apart series of arcuate transverse base ledges 40 join integrally each succeeding pair of end walls 38. 39 of confronting lugs. The end walls 38, $9 of the several lugs are disposed radiallyof the roll and converge inwardly of the outer periphery=..-

A sheet metal cap shaped body 3'! hasa right angular :band 36 which in turn is formed with a right angular flange 35 which is disposed parallel to the part 3'! of this body. The flange 35 of the body 3'! overlies the inner face of flange 29 of the drum and is operatively secured thereto. This disposes the band 36 in peripheral alignment with the arcuate, base portions 4i! forming the bottoms of the slots 32 of the drum as shownin Figure 7, and disposes body 31 vertically in the drum parallel with side wall 24. This body 31 isformed with a central right angularly disposed outturned hub 42 the outer edge. of which is flush with the outer face of flange 29. It willbeseen from Figures 9 and 10, that tangs.33

which are pointed, are upset from openings 34 stamped. in the bands 25, 29 and 281), so as to project outwardly thereof and form a roughened surface thereupon. Y The feed rolls illustrated in connection with the cast type and the sheet metal stamped-outtype both have the same characteristics in use and When assembled on the complete machine for dispensing adhesive or sticky tape, either type-0f feed roll willbe located in the forward end of the machine, as my copending application will disclose.

In this mounting of the feed roll, upon its proper bearings, there is located inside ofchamber 22-23 of Figure 3, or'chamber 36, 3101' Figure '7, the intermittent feed mechanism of the machine. This intermittentfeed mechanism includes a detent that extends out of the chamber and projects movably and retractingly into the transverse slots It or 32 of the feed roll. Also projecting from outside of the feed roll into the channel is a tappet. It extends into :oneof. the transverse slots thereof. Into any of the slots |6,or 32 of the feed roll, according to thetype concerned, project a row of needles (not shown) which perform the function of stripping or severving the adhesive or sticky tape which adheres onto the roll as itis wound up thereupon. These needles are also retracted out of these slots immediately upon completion of the tape severing operation.

From the foregoing, it is seen that the feed roll is of special construction shaped with the object in view of fitting same to receive internally certain parts of the operating mechanism for dispensing the adhesive or sticky tape, and adapting same to be associated with externally arranged tape severing means as well. I do not confine myself to the exact details of construction herein described but claim all variations falling within the purview of the appended claims.

What I desire to claim by Letters Patent is:

1. As a new article of manufacture, a cylindrical metal body out transversely at uniformly spaced apart intervals to provide linear grooves and also cut circumferentially in a place at right angles to said grooves to provide annular grooves of greater depth than the transverse grooves and communicating with the latter, whereby there is produced over the effective external area of the body a series of rows of spaced apart lugs having knurled outer faces, said body having on one side thereof a cylindrical chamber of a diameter equal to the peripheral base edges of the transverse slots and communicating with those of the latter slots located at the same side of the body as the chamber is located.

2. A combined sticky tape feed roll and ratchet wheel comprising a circular body formed with a central bore and provided with circumferen- REFERENCES CITED The following references are of record in the file of this patent:
