PATTERN-CYLINDER FOR USE IN THE MANUFACTURE OF PAPER LACE AND THE LIKE.
Specification of Letters Patent.
Patented Oct. 10, 1905.
Application filed February 29,1904. Serial No. 195,921.
[0 Il /Z whom it iii/(Ly cancer/2 Be it known that I, Moses IIEDIANX, a subject of the German Emperor, residing at Berlin, Germany, have invented certain new and useful Improvements in Pattern-Cylinders for Use in the Manufacture of Paper Lace and the Like, of which the following is a specification.
This invention relates to improvements in pattern-cylinders for use in the manufacture of paper lace.
Heretofore for the manufacture of paper lace an engraved untcmpered-steel patterncylinder is usually used, which works in conjunction with a lead cylinder, or an engraved tempered-steel pattern-cylinder is used working in conjunction with a similarly-ternpered smooth steel cylinder.
WVith a tempered engraved pattern-cylinder, which works against a similarly-ternpered smooth cylinder, which is of equal hardness, it is impossible to manufacture line paper lace, because with tempered steel the fineprojecting parts of the pattern easily break or do not sufficiently cut out the paper. The cylinders are also often distorted in the tempering, so that their meeting surfaces require to be polished by means of an emery-wheel. In the latter case it frequently occurs that the cylinders out very badly or that they become quite useless.
The untcmpered engraved cylinders working against lead cylinders also have the disadvantage that the efliciency of the apparatus is very small, and that the manufacture of paper lace is extremely expensive, owing to the wear of the metals, and, moreover, the frequent polishing and turning cause a great loss of time. Further, the lead-dust produced in the manufacture is very dangerous to health, and lead-poisoning of the workmen has frequently occurred. Another (:lisadvantage is the fact that it is very difficult to print the paper, as owing to the continual wear of the lead cylinder the printing-cylinder does not work in coincidence with the engraved steel cylinder and has to be continually adjusted.
The pattern-cylinders to which this invention relates remove all the above-mentioned disadvantages.
Figure 1 of the annexed drawings is aplan view, and Fig. 2 a section, of the improved cylinders.
\Vith these pattern-cylinders paper lace with large and line patterns can be manufactured, and the efliciency of the apparatus is much greater than hitherto.
The improvements in the pattern-cylinders consist in the employment in combination of a tempered-steel cylinder (1', on which the pattern (Z is engraved in relief with an untcmpered-steel cylinder 7), originally smooth, but having the pattern a impressed deep enough into its surface by the rolling action under pressure of the aforesaid tempered cylinder to insure a uniform cutting of the paper.
At the ends of the tempered cylinder are rings 0 of untcmpered steel. The aforesaid rings which serve for protecting the raised pattern when the cylinder is not in use are already used in paper-lace machines; but they have hitherto always been of the same degree of hardness as the pattern on the cylinder.
\Vith the improved cylinders the protecting steel rings are unternpered, since if tempered they would soon prevent or retard the edges of the pattern from cutting the paper, whereas the untcmpered rings are malleable enough to be compressed or spread under the pressure of rolling to allow the tempered pattern to engrave itself on the untcmpered cylinder.
\Vith the improved cylinders polishing or setting of the engravings 01' edges is not necessary, since the lower untempered cylinder fits exactly into the upper engraved cylinder, even if the latter should have become distorted in the tempering.
Contrary to the old systema separate lower cylinder is necessary for each engraved cylinder; but this is a trifling drawback compared with the great advantages obtained and the greater efliciency of the new cylinders.
The combination of a relief engraved tempered-steel cylinder having a softer untempered-steel ring at each end thereof, and an untcmpered softer steel cylinder in juxtaposition to said first-mentioned cylinder, on which softer steel cylinder the pattern has been impressed by rotation under pressure against the tempered cylinder for the purpose set forth.
.In witness whereof I have signed this specification in the presence of two witnesses.
MOSES HEIMANN.
