MEANS FOR ROLLING UP LEAF METAL.
v SPECIFICATION forming part of Letters Patent No. 795,023, dated July 18, 1905.
Application filed February 27, 1905. Serial No. 247,635.
To It 'IU/I/UTI'I/ fl; may concern.-
Be it known that I, O'r'ro BLANKMEISTER, a subject of the German Emperor, residing at Dresden, Germany, have invented certain new and useful Improvements in Means for Rolling Up Leaf Metal, of which the following is a specification.
The present invention relates to improvements in methods or means employed in rolling up leaf metal for storing or transit.
Hitherto it has been the practice to wind up the band of leaf metal simultaneously with a web of paper of the same width, which serves as, backing. The metallic band may lie loosely on the web or may be attached thereto by means of an adhesive agent. The disadvantage of pasting the metal to the paper is that on subsequent unwinding of the roll the leaf does not strip off readily, so that it is impossible to feed the leaf to the stamping or other press with the requisite rapidity, and there is great liability of the material being damaged. To overcome this defect, it has been customary to apply powder or bolus to the paper for the purpose of rendering more ready detachment of the metal possible. Such methods, however, have not been attended with much success.
According to my invention the above-mentioned inconvenience is entirely overcome by applying between the paper backing and the marginal portions of the metal ribbons or strips of paper, fabric, or like suitable material, which may or may not be coated with an adhesive medium to cause marginal adherence between the leaf metal and the paper backing.
In the event of the leaf metal being wound (as is a frequent practice) in a roll of considerable width, destined to be subsequently slit into a number of narrower rolls of the breadth required for the industrial purpose to which the leaf is to be applied, 1 not only apply paper strips at the edges of the metallic band, but also along the lines on which the roll is to be cut, so that after the severance of the wide roll of leaf metal the edges of each resulting narrower roll present intermediate strips.
My invention is illustrated in the accompa- 5 nying drawings, in which Figure 1 is an end elevation of a roll of leaf metal which has been wound up spirally together with a paper web and intermediate carrying strips. Fig. 2 is a vertical section through Fig. 1. Fig. 3 is a plan of Fig. 1. Fig. 4 is a section through one coil of the roll. Fig. 5 is a plan of a roll of treble width destined to be slit transversely to form three-narrow rolls.
Referring more particularly to Figs. 1 to 4, a is a paper web which forms the backing for the metallic band 0. Between the web and the metal leaf I inter-pose marginal strips 7), of paper, fabric, or any other suitable mate- 5 rial. These strips 5 may, if desired, be coated with an adhesive medium, so as to cause the metallic band 0 to be held to the paper web a, without the latter, however, coming directlyin intimate contact all over its sur- 7 face with the leaf metal.
To provide for absolutely certain detachment of the band 0 from the web a under all conditions, the latter may previous to winding be treated with powder, bolus, or the like in well-known manner, or a band of foil may in winding be interposed between the web a and the band 0. It is, however, by no means necessary to take such precautionary meas ures.
Referring to Fig. 5, the leaf metal 0 is of treble width and wound up with a web of paper a of corresponding dimensions. At the edges strips Z) are interposed in the manner above described, and on the lines {0 00 along which 5 the roll is to be subsequently out, like strips 6 of double the width of the strips 7) are inserted. After slitting the roll on the lines w there thus result three rolls of the normal width desired each provided with narrow mar- 9 ginal strips 5 b or 6 Z). These latter strips may, like the strips 6, be provided with an adhesive agent, if desired.
WVith rolls wound in the above-described manner the leaf-metal band being carried by the strips I), can be very easily detached from the paper web (with which it does not come in intimate contact) without risk of injury. It
can thus be more quickly fed to the stampingpress or other machine than is ordinarily the case now.
The fact that when the strips Z) are pasted to the metal bands narrow marginal portions of the latter are converted into waste is a point of little consequence in practice, since the loss is more than made up for by the increased speed, and therefore saving of labor, at which the stamping of the leaf metal can be carried on, and since the paper'web in general practice does not require to be powdered or otherwise treated economy is effected in this respect also.
In winding rolls according to the present invention the ordinary winding machinery for such purposes may be used, special devices being fitted for guiding the strips 5.
What I claim, and desire to secure by Letters Patent of the United States, is
1. In combination, a band of leaf metal, a paper-Web backing for the same, and marginal strips of suitable material interposed between the said leaf metal and said paper backing, substantially as and for the purpose set forth.
2. In combination, a band of leaf metal, a
paper-web backing for the same,,and adhesive marginal strips of suitable material interposed between the leaf metal and the paper, substantially as and for the purpose set forth.
3. In combination, a band of leaf metal, a backing for the same and strips of suitable material longitudinally interposed between the leaf metal and the backing, substantially as and for the purpose set forth.
4:. In combination, a band of leaf metal, a backing for the same, and adhesive strips longitudinally interposed between the leaf metal and the backing, substantially as and for the purpose set forth.
5. A roll of leaf metal wound with a paperweb backing, having longitudinal strips of suitable material, interposed between the leaf metal and the paper web, substantially as and for the purpose set forth.
In testimony whereof I afliX my signature in presence of two witnesses.
OTTO BLANKMEISTER.
