a 1 in vunii'i on all of loops, each loop-crossing the head oil the cylinder suhstanially on a. long diameter and lying on the curred side surface of the cylinder parallel to the aids. The angle of each loop varied from the plane oi the preceding loop to distrilnitc the material over the sides of the package. the material being preferably so placed that the lonn itudinal edges of the portions oi? the strip covering the sides are slightly overhniiped. While the machine disclosed heat illustrates Wrapping lay means of a sinjrle strip such av limitation is obviously not essential to the invention.

In the preferred form of the invention each loop is spaced slightly away from the center of the cylinder. le ving a hole in the Wrapping at each end for the admission of a pole or shaft which may he used to support the iaclizage, which is ndinarily a. bolt or roll of sheet material, as fabric. the wrap ping being; left in position until. the material is used.

In the accompanying drawings I have shown a machine for Wrapping a. cylindrical. package by means of strip material, thesaine embodying the tli'eatures of the invention in.

the preferred forum in the drawings:

Figure 1 is a side elevation.

Figure 2 is a. section oi? the machine on the line 2-2 of Figure 1.

Referring: to the drawings hv numerals, each of which is used to indicate the some or similar parts in the different figures, the machine. as shown. comprises a frame 1 pro-- vidcd with a hearing 2 .tor a vertical shaft is provided with our arms 53 supportino the roller sha'lts 9, each oi which has a liiearinnj 10 at each end, one said hearing being located in each oi? the four arms 8. The rotary carriage 5 is secured at its centerto the upper end of the sh aft 8 and the carriage and shaft "e in the form of the liy e heve. gnarl" l4:

con i he held secured to the shaxlft ii and meshing with a second hovel rear 15' mounted on a horizontal shaft 16 which turns in suital'ile bearings 17 in the 'lramc, the h'llltl sl'iaii't liieinp, driven in any suitz'ihlc manner, as by means oi. a pol icy 1.8 thereon engan eifl lay a drive belt 19 from any suitable sou Lie of power.

The hearing; 52 carries secured thereto a statiifznary toothed near 52],, Which stationary {rear 2i i'iiesl'ies with a planetary gear 252! which rotates on a stud 24E monntedin suitahle hearings 27 carried hythe rotary carriage 5. The bevel c e'ar is carried by and secured to the pla netar gear 22 onthe top thereoi and coanially placed in relatii'in thereto. The stationary gear 9.1, planetary near i the hei' 'cl gcar 28 are all in horif planes, their area lacing vertical.

The bevel near E28 meshes with a second hovel Q9111 on a horizontal shaft 30 mounted in suitahle hearings in. the carriage 5 and carrying]; thereon a toothed sprocket 31 which drives a chain 353 meshing with a second sprocket secured to the shaft 10 of the roller 7, the same lacing knurled or rongrheiied to engage the package which is thus slowly rotated about its axis to provide for variation of the angles of the respective successive loops of the paper strip as it is wound on the cylinder.

' The cylindrical body being Wrapped may in position on the carriage 5 lo; gravitv or in any suitable manner, but in the IFOI'H'I illuriitrated a Weight or presscr foot 35 is shown. the same heing pivotally mounted to rotate in a horizontalplane on a vertical shaft 36 in an upright hearing 37 carried on a horizontal arm 38 intcrmediiately supported on journals andfjournal hearings 3% the latter being carried lin an upright 4:0

forming part oi the frame of the machine.

The upright hearing 37 la in the Form oi the inveijition shown;provided with horizontal ournala ll engragrirureuitalile hearings 42 onsaid arm 38 so that the prcsscr foot or Weight 35 which, in the form shown, enpages the cylindrical paclmge from above by means of four rollers lihmay not only he rotated about a vertical axis in a horizontal, plane, but rocked about the arm 38 to per mit the rollers to conform to the position of the package. The rollers 42 as shown. are mounted one on each end of two shafts 44 mounted in fore and aft arms 45 of the preeser foot 35 and the preseer fliotmlh is shown as counter balanced by means of a weight 46 mounted for adJust-ment along the .arm 38 on the opposite end thereof from the presser foot and on the opposite side of the bearing 39.

The presser foot may be raised at the will of the operator in any suitable manner as by means of a flexible tension member 47 having at its end a suitable grip 48, the tension member being passed over pulleys 49 and 50 suspended from the ceiling, or any suitable support.

The strip wrapping material 55 is fed to the cylindrical package 4 from a spool 56 mounted on the frame of the machine on a suitable stud 57 seated in a bracket 58 and controlled by any suitable tension member, as the plate spring 59. If itis desired to wrapby means of two strips fed simulta' neously this may be done by feeding a second strip of wrapping material from a second spool 66, the same being on a stud 67.

In the operation of the machine the body 4 to be wrapped, which is ordinarily a cylindrical bolt or roll of fabric or other sheet material, is first placed on the rollers 6, 7 of the rotary carriage 5 and the strip material 55, which is preferably in the form of a single strip, though this is not essential to the invention, is led from the spool 56 to the package 4 and the end 65 of the material is fastened to the package or connected to the package in any suitable manner. The drivin mechanism, which is preferably at rest W en the package is placed, is then started causing the package or cylindrical article to rotate about a vertical axis which is at right angles to the axis of the cylinder and preferably'intersects it intermediately or substantially at the center.

The rotation of the cylindrical body or "bolt being wrapped, in this direction causes the strip material to be rolled about the cylinder on the line of the intersection of a plane parallel to and near or at the axis with the curved sides and flat ends of the cylinder.

The rotation of the carriage 5 also causes a planetary motion of the gear 22 about the stationary gear 21 with which it meshes, rotating the gear 22, also the bevel gear 28cmried thereby, which in turn meshes with the bevel gear 29 carrying the sprocket 31 which drives a chain 32 which in turn meshes with sprocket 33 driving the friction roller or knurled roller 7 which is in engagement with the bolt of cloth or body 42. This causes the bodybeing Wrapped to rotate about its central axis 60 with a motion which is very slow in comparison with the rotation about thevertical axis 61 already described. This rotation, which may be referred to as the secondary motion, causes the angle at which the loops of material are laid on the cylinder, as described, to be varied at each turn preferably by an angle which, at the cylindrical surface, encloses an are substantially equal to the width of the strip or st rips so that the strip material forming each turn overlaps as to one longitudinal edge. the adjacent longitudinal edge of the next preceding strip, gi v ing a continuous layer of material covering the curved sides 62 of the cylinder. The ends of each package are covered by the end portions of the loops of material described,

which overlap to a much greater extent near the centers of the ends than at the sides.

In the operation of the machine. as shown, the spool 56 is so placed. that the plane of the side edge 63 of the paper strip 55 forming each loop is spaced slightly away from the center leaving a central opening (34- which is coaxial with the cylinder 4. This makes it possible to mount the bolt of cloth on a pole or shaft passed through the center to support the cloth without first unwrapping. By this arrangement the paper wrapping may he left on the sheet material or cloth until it is used. By use of the machine most satis factory, quick and cheap wrapping of this type of package is accomplished.

I have thus described specifically and in detail a machine embodying my invention in the preferred form in order that the nature and operation of the same may be clearly understood, however, the specific terms hcrcin are used descriptivcly rather than in a limiting sense, the scope of the invention being defined in the claims.
