FOLDING MACHINE Filed May 25, 1945 2 Sheets-Sheet 2 Patented May 14, 1946 UNITED STATES PATENT OFFICE FOLDING MACHINE Christian Christiansen, Swamps eott, Mass, as-
signor to Rotary Machine Company,'Inc'., Lynn,
Mass, a corporation of Massachusetts Application May 25, 1945, Serial No. 595,815 4'Claims. (01. 12 17 The present invention relates to rotary folding and pressing machines for folding a cemented binding or galloon around the edge of a piece of material such as an insole to which it has been previously stitched and then pressing the binding firmly against the opposite side of the materialto, cause the binding to adhere to the material. In describing the invention it is convenient to refer to the piece of material to which the binding is to be applied as an insole since the machine isparticularly intended for binding insoles. It will be understood that cement is applied first to one face or to a porticnof one face of the binding'and allowed to dry, before the binding is stitched around the edge of the insole. The insole with the binding attached is then passed throughthe machine which progressively folds and stretches the binding around the edgeof the insole bringing it into contactwith the opposite side of the insole and pressing it firmly into position. r r
The machine embodying the present invention Fig. 6' isan elevation, partly in section, showing the driving means for the feeding and folding mechanism of the rotary head.
The working elementsof the machine consist essentially of a rotary head 38 on which is mounted a series of notched or somewhat crescent sleeve. 43. which is fixed in abearing head and bushing 44 secured to the overhanging arm 45. The shafts arealternately longer and shorter so. asto permit. a nesting of the pinions 4| in step formation as shown in Fig. 5. The mechanism and operation are more fully described in is an improvement on the rotary folding machine shown in the patent to Ridderstrom No. 1,743,286, January 14, 1930. The Ridderstrom machine was intended primarily to operate on relatively thin soft stock, such as binding stitched to the edges of the vamps of womens shoes, while the machine embodying the present invention is particularly adapted; to bind the edges of relativelythick, sti
pieces ofstock, such as innersoles.
The general construction is the same as that shown in the Ridderstrom patent to which reference may be had for detailed information. The improvement forming the subject matter of the present application has to do with feeding mechanism which will not only "turn the binding around the relatively thick edge of an innersole but willalso stretch it tight and press it against the edge of the innersole as Well as against the top and bottom surfaces.
In the drawings:
Fig. 1 is a side elevation of the machine, certain parts being shown in section.
Fig. 2 is a section on line 22 of Fig. 1.
Fig. 3 shows side elevations of the feed wheel and the wiper wheel.
Fig. 4 is a fragmentary side elevation partly in section illustrating the work supporting and guiding mechanism, the folding mechanism, the edge turning device, and the feeding and wiper rolls.
Fig. 5 is a fragmentary sectional plan view taken on a curve corresponding to the circumference of the rotary head.
: inner end of said shaft is engagedby a cam I06 which-is actuated by the treadle 54 against the tension of a spring 55. A spring I08 surrounding the shaft 89 is adapted to return said, shaft to its normal inoperative position. The presser point is heated by an electrical heating unit l3. The feed wheel, wiper wheel and edge turning member are mounted on a bracket I!) carried by a sleeve 41 which is Partially rotated by downward motion of the treadle 54. The spring 55, previously referred to, tends normally to urge the bracket IS, the feed wheel 14, wiper wheel I I and edge turning member 19 towards the presser point l2 and the pressing disks 40. For insertion of the work the bracket I9 and the parts carried thereby may be depressed by means of treadle 54, which at the same time shifts the presser point I! away from the edge turning member 19. The function of the heating and pressing point 12 is to soften the cement slightly and to hold the work firmly down on the feed wheel 14.
' The rotary head38 secured to a shaft 46 is driven by the shaft 21 acting through the spiral gears 26 and 25. Below the main shaft 21 is a shaft 66 which is driven from the main shaft by the worm 63 which meshes with a worm gear 62 (see Fig. 2) on a cross shaft 6|. On this cross shaft BI is a spiral gear 64 meshing with a spiral gear 65 on the shaft 66. At the front end of the shaft 66 is a member I4 at a slight angle to the shaft 66 which acts as a universal joint between the shaft 66 and the hub of a spur gear I6 which is driven thereby. This spur gear I6 meshes with a bevelled gear II on a shaft I8 journalled in the supporting bracket I9. Fast on the shaft I8 is a gear 20 which meshes with a smaller gear 2I rotatably mounted on a fixed shaft 22 also in the bracket I9. Another gear 23 of larger diameter than the gear 2| is secured to the gear 2I and itself meshes with the gear 24 forming the hub of the wiper wheel I I which is rotatably mounted on the shaft I8. The arrangement of the gearing is such that the rotation of the shaft I8 turns the wiper wheel II in the same direction as that of the feed wheel I4 but at a speed two and onefourth times that of the feed wheel I4. The feed wheel I4 (see Fig. 3) is grooved to provide inclined teeth or ribs (1 which, as viewed in Fig. 3, slant downwardly toward the wiper wheel. The wiper wheel has a bevelled face which is also grooved to provide ribs b as shown in Fig. 3. These ribs also slant as is shown in Fig. 3. It will be seen that the feed wheel has a working surface formed by ribs which slope so that the trailing ends of the ribs are towards the edge of the work, i. e., towards the wiper wheel, while the wiper wheel has a bevelled working surface at an angle to the working surface of the feed wheel and that the ribs which form the surface of the wiper wheel slope so that the leading ends are at the smaller diameter of the bevelled surface and the trailing ends are at the larger diameter.
The operation of my machine is as follows: The binding or galloon 30 having been provided with a cemented area 33 along the edge of the face which is to be folded into contact with the upper side of the insole S is stitched as shown at 3| to the edge of the insole, The insole is placed in the machine after the bracket I9, carrying the feed Wheel I4 and wiper wheel II, has been swung downwardly and the presser point l2 has been shifted away from the edge turning member I9 by depressing the treadle 54. The operator inserts the insole by ushing it sidewise, i. e., to the right in Fig. 1, to bring the edge of the binding firmly against the edge turning member I9. The presser point I2 and the bracket I9 are then released so that they come into working position. The presser point then presses down on the upper surface of the insole while the feed wheel I4 and wiper wheel II press the insole strongly in the direction of the rotary head which is unyieldingly supported. The machine is then started by depressing the treadle 32 and the feed wheel I4 and wiper wheel II combined with the action of the disks 40 feed the insole forwardly past the edge turning member 19. The ribs or teeth a on the feed wheel I4 tend to crowd the insole toward the wiper wheel I I. The wiper wheel I I, which has a greater surface speed than that of the feed wheel I4 tends to stretch the binding tightly around the edge of the insole and. press it firmly against it. As the binding passes the heated presser point I2 the cement is softened slightly so that when the edge of the binding passes under the notched presser disks 46 it is soft and adheres readily to the s'urface'of the insole. The action of the rotary notched presser disks is exactly the same as is described in the Ridderstrom patent already referred to and, therefore, need not be decribed in detail here.
In actual operation the binding will be found to be stretched tightly around the edge of the insole and secured firmly and smoothly to the upper surface of the insole.
I claim:
1.
