Definitions
- the present invention relates to a method and a machine for wrapping rolls and more particularly newsprint paper rolls.
- Rolls of newsprint paper normally vary in length from 18" to 72 and in diameter from 28 to 40 and the weight of each roll of paper varies from 200 to approximately 1600 lbs. Production of various sizes of rolls varies in quantity or number of rolls per ton according to orders on hand at any one time. The production of newsprint paper is normally carried out throughout the full 24 hour period each day, generally in three 8 hour working shifts, not including Sundays. The actual number of rolls produced in one 24 hour day at any one mill may run from 100 or 200 up to possibly 1800 or 2000 rolls in the larger mills. Approximately ten-and one half million tons of newsprint paper is manufactured per year in the world at the present time.
- the present method of wrapping rolls of newsprint paper is by laying on the floor a pre cut length of wrapping paper which is then rolled onto the wrapping paper and rolled up and the overhanging ends of the wrapping paper are crimped into the ends of the roll by hand.
- Reinforcing bands or strips of wrapping paper are included in the above operation. These bands may be placed inside or outside of the main wrapping paper and may be located at each end of the roll and sometimes at the center also. Glue is applied to one side of the band paper.
- the wrappedrolls are then rolled between two heated steel discs which are brought together by means of air cylinders and the hand crimped ends are thereby compressed tightly up against the end of the roll of paper, an inside heavy paper disc having previously been inserted in the end of the roll before the hand crimping was done as stated above.
- the heated discs are then relieved from the ends of the Wrapped roll and an outside end disc of heavy paper on which glue has been applied, is inserted.
- the heated discs are then again pressed up against the ends of the wrapped roll of newsprint until the glue is dry, thus sealing the ends of the roll.
- the completely wrapped roll of newsprint paper is then rolled onto a platform scale where it is weighed and marked ready for shipment.
- the object of this invention is to reduce the cost of this operation per ton of paper manufactured and to provide a better wrapping job by reducing the amount of labour required, reducing the amount of floor space required, providing a more convenient method and centralization of operations.
- one roll could be wrapped every 2 minutes or 30 rolls per hour amounting to 720 rolls per 24 hour day.
- one roll could be wrapped every minute or 60 rolls per hour amounting to 1440 rolls per 24 hour day.

11 Claims. (Cl. 53-380) The present invention relates to a method and a machine for wrapping rolls and more particularly newsprint paper rolls.
Because of the very large quantities of newsprint paper manufactured and shipped throughout the world, the main use of this machine will be for wrapping rolls of newsprint paper.
Rolls of newsprint paper normally vary in length from 18" to 72 and in diameter from 28 to 40 and the weight of each roll of paper varies from 200 to approximately 1600 lbs. Production of various sizes of rolls varies in quantity or number of rolls per ton according to orders on hand at any one time. The production of newsprint paper is normally carried out throughout the full 24 hour period each day, generally in three 8 hour working shifts, not including Sundays. The actual number of rolls produced in one 24 hour day at any one mill may run from 100 or 200 up to possibly 1800 or 2000 rolls in the larger mills. Approximately ten-and one half million tons of newsprint paper is manufactured per year in the world at the present time.
The present method of wrapping rolls of newsprint paper is by laying on the floor a pre cut length of wrapping paper which is then rolled onto the wrapping paper and rolled up and the overhanging ends of the wrapping paper are crimped into the ends of the roll by hand. Reinforcing bands or strips of wrapping paper, generally to 12" wide, are included in the above operation. These bands may be placed inside or outside of the main wrapping paper and may be located at each end of the roll and sometimes at the center also. Glue is applied to one side of the band paper. The wrappedrolls are then rolled between two heated steel discs which are brought together by means of air cylinders and the hand crimped ends are thereby compressed tightly up against the end of the roll of paper, an inside heavy paper disc having previously been inserted in the end of the roll before the hand crimping was done as stated above. The heated discs are then relieved from the ends of the Wrapped roll and an outside end disc of heavy paper on which glue has been applied, is inserted. The heated discs are then again pressed up against the ends of the wrapped roll of newsprint until the glue is dry, thus sealing the ends of the roll. The completely wrapped roll of newsprint paper is then rolled onto a platform scale where it is weighed and marked ready for shipment.
The object of this invention is to reduce the cost of this operation per ton of paper manufactured and to provide a better wrapping job by reducing the amount of labour required, reducing the amount of floor space required, providing a more convenient method and centralization of operations.
With the machine according to the present invention two operators are required as a minimum for each 8 hour shift. Their work would include wrapping, crimping and heading the paper rolls complete for weighing and marking. Withtwo operators and presuming that 2,803,935 Patented Aug. 27, 1957 "ice they would bring the rolls of newsprint paper from the discharge end of the paper machine or machines, look after lining up various widths of rolls in an average size storage space in front of the roll wrapping machine, Wrap, crimp and apply head discs, prepare the head discs and apply glue to the same, load the machine with rolls of wrapping paper and band rolls, and in fact carry out all the above operations, it is estimated from present experience that two operators could handle an average of one roll every three minutes or 20 rolls per hour amounting to a total of 480 rolls per 24 hour day. With one extra helper one roll could be wrapped every 2 minutes or 30 rolls per hour amounting to 720 rolls per 24 hour day. With two extra helpers and assuming that all four could act as operators performing any or all operations, one roll could be wrapped every minute or 60 rolls per hour amounting to 1440 rolls per 24 hour day.
The above compares with the labour requirements of the conventional hand wrapping method according to which seven to eleven men per shift or twenty-one to thirty-three men per 24 hour day are required to hand wrap 1000 rolls per 24 hour day.
The present invention will be more clearly understood with reference to the attached drawings in which:
Figure 1 is a side elevation of an embodiment of the invention;
Figure 2 is a cross-section on line 22 of Figure 1;
Figure 3 is a top view of Figure 1;

Figure 8 is a perspective view as in Figure 7 showing the bands and the crimping operation;
Figures 9 and 10 are details of one header during the application of the paper disk;
Figure 11 is a diagrammatic side elevation of the machine in the heading operation;
Figure 12 is a perspective view of the completely wrapped roll;
Figures 13, 14 and 15 are perspective views and Figures 16 and 17 are planviews showing the crimper in detail;
Figure 18 is a diagrammatic perspective view of the chains and the points of attachment of these chains to the header frames;
Figure 19 is a perspective detail of one point of attachment of the chain to the header frame.
Referring now more particularly to the drawings in l which like reference characters indicate like elements throughout, the machine comprises two horizontal rollers 1, one or both motor driven, capable of rotating on their axis by means of shaft 2 projecting from the ends of said rollers and resting on a bearing (not shown); the rollers 1 are disposed within a rectangular opening F within the floor F slightly below floor level, and in the same horizontal plane at a short distance from each other. Plates 3, flush with the floor and slightly above the rollers, bridge the gaps between the edges of the floor and the rollers.
There are two header assemblies which comprise vertical disk shaped header plates 5 facing each other and disposed transversely with respect to the rollers 1, and, sheet metal frames 6 supporting the plates 5 in the above named position, each frame being movably, mounted on two wheels 7 positioned to run on tracks 8 disposed outwardly of the rollers. The plates 3 are provided with longitudinal cuts 4 to allow passage of the header frames.
. Each header plate 5 has a centrally recessed portion. 9
'1 a an opening 10, surrounded by rubber or other airtight material, and connected to a source of suction through pipe 11. The header assemblies are driven by fluid pressure cylinders 12 attached to the frame 6, the piston rods 13 of said cylinders 12 being connected to buttresses 14. The header assemblies are connected to each other by two endless chains 15, show-n diagrammatically in Fig ure 18 positioned one above the other and riding on sprocket wheels 16. Each chain is attached to each header on one side only, these sides being opposite to each other and to each side of-each header; only one chain isattached v(see Figure 19) by means'of angle brackets 17, while the other chain rides freely on a horizontal wooden shoe 18 rounded at its extremities 1 9 and supported by an angle bracket 20 which'is secured to the frame -6. This arrangement keeps the header assemblie at equal distances from the-centre of the machine, or centre of the rollers 1, at all-times, said assembly having been so positioned initially. Each-header assembly comprises a crimper 21 formed of an-integral piece of cast metal, movable through the header plate -5 'inthe direction of movement of the header assembly; Each :crirnper' 21 is driven by the piston rod 22 of cylinder "23 attached to the header frame '6. The left' hand-cr-imper isshown in detail in Figures 13 to '17; the other crimper has a similar shape but is a mirror image-of theil-lustrated crimper. The crimper comprises a twisted opera-ting surface 24 limited atits ends by mutually perpendicular straight edges 25 and 26 and at its sides by a curved edge 27 extending partially in a lip 28, and by a planar ogee curved edge 29. The rest of the crimper is formed by a cylindrical surface 30 adjacent-the cu-rvededge 27, plane surfaces 31 and 32 adjacent the ogee curved edge 29 and the edge 26, and a plane surface 33 as the remaining face. In the present preferred embodiment, the back of the crimper is cut out, ;as shown-at 34, for purposes of economy; a thin reinforcing plate-like portion or web 35 being left. During *operation,--the crimper is positioned with the edge 25 horizontal, the curved edge 27 adjacent the bottom portionLof the edge of the paperroll, the lip 28 under the roll and the edge 26 adjacentthe end faces of the roll. The outstanding margin '56 (see Figures '7 and 8) of the wrapping paper upon rotation of the roll is engaged by edge '25 and gradually folded against the end face of the roll by the operating surface 24 and the edge 26. The radius of curvatureof the curved edge 27 is of the same order :of 'magnitude'as the radius of the paper roll. The crimper 21 may be further provided with ,a roller '36 slightly projecting beyond the edge 26 and held bythe ears 37 of a plate '38 which is attached to the plane surface 32 of the crimper by means of screws .(not shown) adapted *to 'pass throughholes '39. Two tubular holes 40 and 41, are provided in the crimper 21;hole 40 accommodates the piston rod 22 of the cylinder 23 also fastened by the "last mentioned screws and the threaded hole 41 accommodates a supporting shaft (not shown) screwed into'said hole 41 and freely slidable in a'bearing (not shown) attached to the header frame 6.
As shown in Figures 1 to'3, a lifting device is positioned olf centre between the. rollers 1, said lifting device comprising a horizontal shaft 42 driven by vertically disposed cylinders .43.
The operation of the machine is as follows: a roll of paper 50 is rolledonto the rollers 1 without attempting to centre it (Figure .4). The headers 5 position the paper centrally with respect to the center line 51 whichflis also the centre line of the wrapping paper (Figure 5) The h a er S e h n d p a e ou ardly (Figure A shor por ion .52 of the p pe o thsrq i e rol d and the s i h ly w e r pp n p pe 5. s in e ted be en the roll and the unrolled portion 52 (Figure 7 The roll is then rotated by rollers 1 in thedirection of thearrows of Figure 7 until the cylindrical surface of the roll is completely covered by the wrapping paper 53. Two reinforcing side bands 54, which are disposed marginally flush with the wrapping paper and a .central band .55, all of said bands having previously been coated with adhesive on their inside face, are inserted on the same side of the wrapping paper 53 as the roll 50. The above mentioned rotation is continued and simultaneously the outstanding margins 56 of the wrapping paper 53 and bands 54 are crimped against the end faces of the roll by the crimpers 21 which have, in the meantime, been impelled from behind the header plates 5 by the cylinders 23. Adhesive is applied to the end margin 57 of the wrapping paper 53. On further rotation, the bands 54 and 55 become external with respect to said wrapping paper 53. When the bands 54 and 55 are completely rolled on the roll 50, the machine is stopped and the crimpers 21 are pulled back behind the plates 5. A paper disk 58 slightly smaller in radius than the roll 50 is brought in contact with the opening 10 and held there y su on (P gwo d k 58 s thu app ed on ea eade plats 5- .A ye o adh i is appl e on y to the margin of the disk 58 and the headers are again b ugh a a n h ends o t srs t pply s d sk q5 o id h ders a p ided w h he t n m an ot shown) t sp e h dryin o t adhes ve. and a substantial pressure is provided (Figure 11'). The heade s a he pu d ba and t ssomp ts y app roll is ejected by the lifting device 42, 43 on the side opposite to that from which said roll entered the machine. Figure 12 shows the completely wrapped roll.
It can be seen from the foregoing description that at no time is the wrapping paper, the bands or the disks directly glued to the paper of the roll itself. The wrapping paper and the bands are fed to the machine by means which are the subject of a co-pending application.
