1961. rlihis application Apr. 25, 1966, Ser. No. 549,768 9 Claims. (Cl. 118-409) This is a continuation application of application S.N. 99,756, now abandoned, filed by Frank D. Karkoska on Mar. 31, 1961.

This invention relates to a device for imparting both a rotational and a translational movement, that is, a helical movement, to a cylinder or rod. The invention is particularly useful in winding strip foil material onto a cylinder. It is specifically adapted to winding a strip of material onto a slender cylinder to form simulated needles on an artificial Christmas tree. The cylinder which is advanced through the device is imparted with a rotational as well as a translational movement, and as the helically advancing cylinder leaves the device a strip material is wound around it. It is apparent that the invention greatly facilitates the helical winding of a strip material around a cylinder.

The ratio of the rotational movement with respect to the translational movement can be varied by varying the angle at which the cylinder engages a roller, and consequently the pitch at which the strip material is wound around the cylinder can be varied.

The invention also comprehends the application of glue to the cylinder before the strip material is helically wound thereon.

In the diagrammatic drawings:

FIGURE 1 is a plan view of the entire device of the invention;

FIGURE 2 is an elevation view of the device showing the vertical relation of the various components thereof to each other;

FIGURE 3 is an end elevation view showing the relation of the holder and the feeding roller with respect to the various other components of the device;

FIGURE 4 is a cross-sectional View taken along line 4 4 of FIGURE 1; and

FIGURES 5, 6 and 7 are plan views of a portion of the device each showing the holder in dierent oblique positions with respect to the feeding roller.

Referring to the illustrative embodiment in FIGURES 1, 2 and 3 of the drawings, there is shown a frame 10 having an upper plate 11 and a lower plate 12. A spacer 13 located near one end of the frame 18 is attached by

screws

14 and 15 tothe upper and lower plates, respectively. Near the other end of the frame there is provided a block 16 which is attached to the lower plate by a screw 17. An adjusting screw 18 passes through an aperture in the upper plate 11 and is threadably received by the block 16 whereby, upon actuation of screw 1S, relative movement occurs between the feeding roller 28 and the guide 34 such that the roller moves toward and away from the U-shaped cut-out portion '33 as seen in FIG- URES 2 and 3.

An electric motor 19 is mounted on the frame by means of a bracket 20. A conventional foot pedal operated switch 21 which includes a rheostat is employed to vary the speed of the motor 19. An electric current passes through leads in cord 21a, through the switch 21 and through the leads in cord 2lb to the motor 19. The output shaft 22 of the motor 19 has iixedly mounted thereon a pulley 23 which drives an endless belt 24 which in turn drives a pulley 25. A drive shaft 26 mounted for rotation in

bearings

27 and 27a is xedly attached to the pulley 25. The end of the drive shaft 26 which is oppo- 3,354,866 Patented Nov. 28, 1967 site the pulley 25 has a feeding roller 28 xedly attached thereto by a nut 29 and a cotter pin 30. The feeding roller is preferably composed of a resilient material, such as rubber, but it can also be composed of a hard material and be knurled to afford a more positive gripping action. Moreover, a knurled feeding roller will cause the cylinder or rod 31 to be embossed which is advantageous in some types of winding operations. FIGURES 3 and 4, particularly show a holder 32 or guide block mounted on the lower plate 12 of the frame adjacent and below the feeding roller 28. The roller is disposed partially between a U-shaped cut out portion 33 in the holder or guide block 32. A guide 34 is fitted and retained in an opening 35 in the holder by means of set

screws

36 and 37. A screw 38 about which the holder 32 can be pivoted secures it to the lower plate 12 of the frame. A washer 39 through which Iscrew 38 passes is disposed between the holder and the lower plate. The holder 32 can be pivoted about the screw 38 into various positions as illustrated in FIGURES 5, 6 and 7. The angle at which the holder is positioned with respect to the plane of rotation of the feeding roller 28 determines the amount of rotatoional and the amount of translational movement which is imparted to the cylinder 31. For example, the amount of rotational movement of the cylinder is greater when the holder is in the position of FIGURE 6 than that in the position of FIGURE 5, but the translational movement of the cylinder when the holder is in the position in FIGURE 5 is greater than that in the position of FIGURE 6. Similarly, when the holder is in the position of FIGURE 7 the rotational movement of the cylinder is greater than that in the position of either FIGURES 5 or 6 whereas the translational movement is less than in either FIGURES 5 or 6. In other words, the rotational movement of the cylinder is inversely proportional to its translational movement.

The workpiece or cylinder enters guide 34 at the entrance end and upon engagement with feeding roller 28 a helical movement is imparted thereto providing the holder makes an oblique angle with respect to the plane` of rotation of the feeding roller. The term oblique is used herein to designate all positions of the holder other than that in which the holder is positioned either exactly perpendicular or exactly parallel to the plane of rotation of the roller. Before the cylinder or workpiece leaves the holder aquantity of glue can be applied to the cylinder. A gluereservoir 40 is supplied to the exit end of the holder through an inlet 41. A valve 42 in inlet 41 determines the amount of glue, if any, which is applied to the cylinder. A trough 43 is provided in the lower side of the -guide 34 which, when it fills up with glue, aids in the coating of the cylinder. An outlet 44 leads from the bottom of the trough 43 and permits the excess glue to drip into a nearby container (not shown). A valve 45 in outlet 44, similar to valve 42, can be adjusted so that the trough is always filled with glue and the excess drips into the container.

It is apparent that the force which roller 28 exerts upon the cylinder 31 upon engagement therewith can be adjusted by means of the adjusting screw 18 which causes roller 28 to move relative to the U-shaped cut out portion 33 in holder 32.

While the preferred embodiment includes a motor and other components to drive the roller 28, the motor components can be omitted or simply disconnected from the roller by removing pulley 24. The roller is then freely rotatable. The cylinder can then be fed or pushed through the holder by hand or by other means (not shown). It will be noted that in this case the roller will impart the same movement to the cylinder as in the case wherein the roller is driven and is employed in feeding or advancing the cylinder.

In a specific example of the invention a thin foil (not shown) having a longitudinal strip portion and a plurality of shreaded transverse strip portions which extend from one marginal edge of the longitudinal strip portion is used in forming the simulated needles of an artificial Christmas tree. The longitudinal strip portion is wound around the thin cylinder 31 and is glued thereto, while the transverse strip portions form the simulated needles which extend in all directions when the longitudinal strip portion is helically wound around the cylinder 31. The cylinder is from about 1/16 to 1/s of an inch in diameter, while the roller 28 is about one inch in diameter. The motor 19 is of a sewing machine motor type which is operable by the foot pedal through the rheostat.
