Description
: ~OS~10~
This invention relates to apparatus for the delivery of sheet material from a roll thereof and is particularly but . not exclusively related to the packaging of coils of sheet metal.
One operation in the packaging of coils of sheet metal strip includes wrapping paper around the outer cylindrical surfaces of the coil. The paper wrap is usually made wider than the axial dimension of the coil so that axially over-hanging portions of paper at each end of the coil can be folded down on to the end faces of the coil and tucked into - the eye.
It is an object of the present invention to provide a new or improved apparatus for the delivery of sheet material which will obviate at least some of the disadvantages associated with known methods of sheet delivery. It is a more specific object of the invention to provide such apparatus for use in the packaging of coils of sheet metal.
In accordance with the above object and remarks, what is being broadly claimed herein is an apparatus for delivery of sheet material which comprises means for supporting two rolls of the said sheet material for delivery from the apparatus in parallel overlapping relation and opposed xoller sets pro-viding a nip between which the leading edge of the sheet mate-rial may be fed. At least one of the sets is a driven set while the or each roller in at least one of the sets has or have a flat along a portion of its circumference whereby, when the flats in the said one roller set are disposed in juxtaposition to the other roller set, a space is afforded between the two sets. There are also provided a third support roller, located on the delivery side of the proposed roller sets, and a moveable cutter blade for the sheet material located between the opposed roller sets and the third support ' -- ,. ~ .
` roller. 10541Q~
With such an arrangement the sheet material may be delivered intermittently, or "inched", from the apparatus upon ~- rotation of the roller sets. Also when the roller sets are stationary with the flat on the or each roller of the one set in juxtaposition to the other set the sheet material may be with-drawn freely from the apparatus through the space between the roller sets.
Such apparatus may conveniently be utilized for the delivery of wrapping paper from a roll thereof supported in the apparatus to the exterior of a coil of sheet metal being packaged by means of apparatus and method described in British patents 1,275,602; 1,434,014 or 1,492,934.
The apparatus preferably further includes means for guiding the leading edge of the sheet material from each roll in substantial alignment with the nip, whereby the sheet material does not pass over either of the roller sets, and the support roller has an upper edge lying in substantially the ` same plane as the nip.
An embodiment of the invention will now be described with reference to the appended drawings wherein:
Figure 1 is an end elevational view of sheet delivery r apparatus in accordance with the invention utilized, in this ~` embodiment, for the delivery of wrapping paper to a coil of sheet metal; a differing diameter of coil to be wrapped being shown in chain-dot outline;
Figure 2 is a more detailed end elevational view, to an enlarged scale, of the delivery apparatus of Figure 1, and Figure 3 is a cross-sectional view on the line III -III of Figure 2.
The specific embodiment of delivery apparatus 10 illustrated in the drawings is adapted to receive two rolls ~(~54~0Z

patent 1,434,014 The delivery apparatus 10 comprises a tandem pair of paper roll supports in the form of open-topped troughs 18-`~ 20 having respective gaps 22-24 at their lower forward faces permitting emergence of wrapping paper from the respective rolls 12-14. Forward of the troughs are provided two co-operating lower and upper roller sets 26-28 defining a nip therebetween for withdrawing the wrapping paper from their - respective rolls. The roller or rollers in each set are conveniently formed of, or covered by, a high friction material such as rubber, and as illustrated, the lower set 26 comprises a single cylindrical roller 26a extending substantially the full width of the troughs 18-20 whilst the upper set 28 comprises a plurality of axially spaced narrow width rollers 28a. Each roller 28a in the upper set is formed with a flat 30 on a portion of its circumference, all of the roller flats being in radial alignment whereby, when the flats 30 are disposed in juxtaposition to the lower ` roller 26a, a space is afforded between the roller sets
2() through which the wrapping paper may be deiive~ed.
One or both of the roller sets 26-28 are driven whereby paper from the rolls 12-14 is delivered intermittently from the apparatus 10; the paper being withdrawn when the cir-cular circumferential parts of the upper rolls 28a are ~5 gripping the paper against the lower roller 26a and with-drawal ceasing intermittently when the flats~30 on the .

upper rollers are in juxtaposition to the lower roller.
When the roller sets are stationary, with the flats 30 of the upper set in juxtaposition with the lower roller 26a~
paper may be withdrawn freely through the space.
~ithin each trough 18-20 which supports a respective roll of paper 12-14 there are positioned yokes 32 attached to pneumatic rams 34 actuated by control valves in such manner that either roll 12-14 may be bodily moved in an axial direction relative to the other roll for varying the degree of overlap of the two sheets of wrapping paper delivered from the apparatus. It will be appreciated that the paper lying between the roller sets 26-28 will also be moved laterally upon any actuation of the rams 34, but that such movement is only carried out when the upper roller flats 30 are juxtapositioned to the lower roller 26a.
In operation the degree of overlap of the two sheets of paper from the rolls 12-14 is adjusted upon a visual assessment by the operator of the desired overall width of the wrapping paper and the roller sets 26-28 are actuated for rotation whereby the paper is delivered intermittently from the apparatus. It will also be appreciated that any tendency for the wrapping paper to track off sideways is reduced with this apparatus because, as the paper is released once during every revolution of the flatted rollers 28a, the natural tendency for the paper to spring : ~0541~2 ~- back to its original central position ensures that th~
paper is delivered straight.
After passing between the roller sets 26-28 the paper passes adjacent a guillotine 36 and finally over a support roller 38 for delivery to the item to be wrapped. Thus, if a coil 16 of sheet metal is being packaged in accordance with the patents and applications hereinbefore referred t~
the wrapping paper will be delivered intermittently from the rolls 12-14 to the coil 16 and attached thereto by adhesive tape. The roller sets 26-28 are then stopped ; with the flats 30 on the upper rollers 28a juxtapositioned to the lower roller 26a and the coil 16 of sheet metal is rotated withdrawing wrapping paper freely from the delivery apparatus until sufficient is wrapped around the coil to envelope it. Rotation of the coil 16 is then ceased and the guillotine 36 is actuated to free the wrapping paper ` from the delivery apparatus. As illustrated herein the guillotine 36 comprises a rotary knife which traverses across the width of the paper by means of a motorised pulley arrangement 36a, but it will be appreciated that any suit-able design of guillotine could be utilised. The wrapped paper is then secured around the coil by further adhesive tape and the remainder of the coil packaging operation is completed.
