March 6, 1962 W. R. SCOTT COILED STRIP RIBBING Filed Sept. 25, 1958 INVENTOR. fw @im BY /Z y @gf/4.
United States Patent Office 3,023,888 Patented Mar. 6, 1962 3,023,888 COILED STRIP RIBBING Wayne R. Scott, Salem, Mass., assignor to Prime Manufacturing Company, Lynn, Mass., a corporation of Massachusetts Filed Sept. 25, 1958, Ser. No. 763,349 2 Claims, (Cl. 206-59) This invention comprises a new and improved coil of composite strip ribbing for welt insoles.
The ribbing to which this invention relates comprises a tough, relatively thick core combined with tape adhesively secured to the sides of the core, or a part thereof, and having portions extending free of the core and presenting ever-tacky or pressure-sensitive adhesive surfaces that may be conveniently attached to the face of a flat insole in the form of a flange or flanges holding thelcore erect and preferably at a slight inward inclination in convenient position to receive the needle of a welt sewing machine.
Ribbing of this general character has been supplied to the shoemaking industry heretofore in coils such as shown, for example, in United States Letters Patent No. 2,343,226, Feb. 29, 1944, Ridderstrom, with the adhesive surfaces of the tape facing inwardly toward the axis of the coil. While such coils have been successfully used, difficulty is encountered from time to time in blocking of the ribbing in the coil so that it does not run freely to the rib applying machine. The coils heretofore known must also be mounted at an appreciable horizontal distance from the rib applying machine in order to enter freely and pass properly through the various introductory gauges of the rib applying machine and this involves inconvenience to the operator.
In laying preformed strip ribbing it has been found that the ribbing sometimes reaches the stripping guide on the rib laying machine with the iianges stuck together beneath the core portion so that the stripping will not properly pass through the guide.
It is not yet wholly certain what causes the iianges to become joined in this way, but investigation shows that the adhesion when it has occurred has at least for the most part occurred in regions of the stripping wound in end convolutions of the supply coil. It is a possibility that during the coiling of the stripping, as one layer of convolutions is completed and another is commenced in superimposed position on the previous layer, involving a change in the direction in which the stripping is tensioned in relation to the axis of the coil, the opposite anges of the stripping in the last applied end convolutions (which flanges lie one underneath and one above the rib portion), are pulled in opposite directions in their own planes so that the flange which is folded back against the rib portion may at one or more points along the stripping be drawn below the bottom edge of the core portion so that its adhesive face there makes contact with the adhesive face of the other ange.
I have discovered that by reversely Winding the ribbing informing the coil all these disadvantages are unexpectedly obviated. The ribbing runs free from the coil without blocking and wherever the coil is located the ribbing reaches the applying machine smoothly, without kinking or twisting, and this permits locating the coil in an overhead position where it is entirely out of the operators way and where it has been impractical to locate the coils previously available to the industry.
These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings in which:
FIG. 1 is a diagrammatic plan view suggesting the reverse winding process,
FIGS. 2 and 3 are sectional views on au enlarged scale showing the disposition of the ribbing in its layers in the coil, and
FIGS. 4 and 5 are similar views of a somewhat diiferent type of ribbing.
The ribbing shown in FIGS. 2 and 3 comprises a rectangular core 10 made of cardboard or similar tough fibrous material forming the inner element of the ribbing. To the opposite sides and one edge of the core 10 is adhesively secured a tape 11 having an ever-tacky or pressure-sensitive adhesive face 11. As shown in FIGS. 2 and 3 the right hand face of the core 10 is completely covered by the tape and this is Shown Ias extended in unfolded condition substantially beyond the exposed edge of the core. The tape is folded continuously around the other edge of the core and adhesively attached to its other side face over perhaps tive-sixths of its area. It is then folded upon itself so as to expose an uncovered long-itudinal zone of the core 1U and extends downwardly substantially beyond the cove-red edge of the core. It will be seen that the adhesively coated surfaces of both the unfolded and folded portions of the tape face in the same direction, that is, toward the left in FIGS. 2 and 3.
The ribbing shown in FIGS. 2 and 3 is reversely wound by apparatus such as that illustrated in FIG. 1. Parallel shafts 13 and 14 carry oppositely rotating feed rolls between which the tape is introduced with its uncoated surfaces upwardly directed. The tape may be led to the feed rolls of the shafts 13 and 14 from the assembling machine where the core and tape `are assembled, or may be led from a coil in which the ribbing is wound with its uncoated surfaces upwardly directed. From these feed rolls the tape passes over a lead screw 15 to a pair of upstanding rolls 18 projecting upwardly from a carriage 16 mounted to slide freely on a transverse shaft 17. The carriage 16 has a leader which runs in the thread of the lead screw 15 and imparts uniform transverse movement to the carriage 16 for determining the pitch and distribution of the turns of the ribbing in the coil.
The carriage 16 has an arm 20 which extends transversely above the coil and carries at its outer end a shouldered feed roll 21 which insures laying the ribbing progressively in a spiral with a pitch determined by the lead screw.
The ribbing is wound on a bobbin 23 carried by a driven shaft 24. In passing from the feed rolls on the shafts 13 and 14 through the upright rolls 18 and the guide roll 21, the ribbing is reversed in its position so that its adhesivecoated faces 11 and 12 are directed outwardl or away from the axis of the coil. When the carriage 16 is moving from right to left or downwardly, as seen in FIG. 1, the projecting portion of the folded tape 12 is at every turn covered by the uncoated and non-tacky projecting portion of the unfolded tape as clearly shown in FIG. 2.
When the carriage 16 is moving from left to right or upwardly, as seen in FIG. l, the adhesivv-coated projecting extension of the unfolded tape engages the uncoated surface of the tape of the adjacent turn. The projecting extension of the folded tape 12 overlies the fold of the tape in the next adjacent turn thus forming a substantially rectangular space 22 between the exposed end of the core in one turn and the covered end of the core in the next adjacent turn. In this layer as before the adhesive-coated surfaces of the tape are directed outwardly and away from the axis of the coil.
In FIGS. 4 and 5 is shown a somewhat different form of ribbing in which the core 30 is triangular in shape and the tape 31 is adhesively secured to one face only of the triangular core. The other two faces of the core are entirely exposed and the tape extends a substantial distance below the base of the core. In winding this ribbing into a coil the adhesive-coated surfaces of the tape 31 underlies the back of the tape which is secured to the core in the abbassa next adjacent turn while the ribbing is being laid in one direction in the coil. In laying this form of ribbing in the other direction on the coil, the adhesive-coated face 31' overlies the long uncoated face of the triangular core 30. In FIGS. 2-5 the direction of laying of the ribbing in forming the core is indicated by arrows.
It will be understood that the uncoated surfaces of the tape 11-12 and 31 are sized or otherwise treated to impart release characteristics to them. Accordingly, when overlapped by the adhesive-coated surfaces in the coil little or no adhesion is developed.
Having thus disclosed my invention and described in detail illustrative embodiments thereof, I claim as new and desire to secure by Letters Patent:
l. As an article of commerce a coil of compo-site ribbing for welt insoles, comprising a at core and tape coated on one surface only with adhesive and secured thereby to opposite sides of the core, one portion of tape covering one side of the core and extending in flat condition so as to expose its adhesive surface beyond the core, and another 20 portion of tape covering a part of the other side of the core and being folded to expose the margin of the core and to direct its adhesive surface in the same direction as that of its unfolded tape, the ribbing being coiled with the said adhesivesurfaces of the tape directed outwardly and away from the axis of the coil, whereby the ribbing 4 will run freely and without sticking when drawn from the coil.
2. As an article of commerce, a coil of strip ribbing comprising a fibrous core and a tape coated on one surface only with a pressure-sensitive adhesive, secured to both sides of the core,having` a atwise extension beyond one edge of the core and a folded extension beyond the other edge of the core, the ribbing being wound in one layer of the coil with the uncoated side of its flatwise extension in contact with the adhesive-coated side of the folded extension of the tape of the next adjacent core and wound in alternate layers of the coil with the atwise extension of the tape in contact with the uncoated back of the tape upon the next adjacent core, and in both layers with the coated pressure sensitive adhesive surfaces of the tape outwardly directed with respect to the axis of the coil.
